7.—Seventh Contribution to the South African Coleopterous Fauna.— By L. PERINGUEY, Director.*

DESCRIPTION OF NEW SPECIES OF COLEOPTERA IN THE COLLECTION OF THE SOUTH AFRICAN MUSEUM. (Plates V. and VI.)

FAMILY CICINDELIDEÆ.

GEN. DROMICA (COSMEMA), Dej.

DROMICA (COSMEMA) CONVEXICOLLIS, n. sp.

Supra æneo-nigra lateribus prothoracis, elytrorum subtusque æneo-cæruleis; femoribus viridibus, tibiis antennarumque articulis basalibus quatuor sub-rufescentibus, labro flavescente, late nigro marginato, palpis flavis, articulo ultimo apice anguste infuscato; capite lato, inter oculos valde longitudinaliter plicato; prothorace latitudine longiore, antice haud sensim postice magis strangulato, disco præsertim in partem posticam valde elevato convexo, fere subgibboso, transversim strigillato; elytris elongatis, pone humeros ad medium inflexis, deinde parum incrassatis, ad apicem acuminatis ibidem spina valida acuta valde divergente utrinque munitis, supra convexis sutura acuta, punctis profundis ad latera obliteratis a basi usque ad apicem æqualibus, interstitio angusto separatis obsitis, in callo humerali macula parva rotunda, pone medium altera ovata supra marginali et prope apicem vitta maculiformi flavo albidis utrinque ornatis.

This species is very closely allied to D. cordicollis, Chaud., which I erroneously stated to be synonymous with D. gruti, Chd.,† and

† Descriptive Catal. S. Afr. Coleoptera, Cicindelidæ, p. 86, Trans. S. Afr. Phil. Soc., vol vii., 1892.

the differences between the two can be detected only by comparing these two species. In D. cordicollis the labrum is only very slightly edged with black, whereas in D. convexicollis it is broadly marginate; the shape and plication of the head are nearly alike in both species, but while the discoidal part of the prothorax of D. cordicollis is highly raised, it falls abruptly behind above the posterior strangulation; in D. convexicollis it is regularly convex and more gibbose, and the prothorax itself is a little narrower; the shape and sculpture of the elytra are the same in both species, but they are narrower in D. convexicollis.

Length 10 mm.; width 2 mm.

Hab. Transvaal (Zoutpansberg). ? Rev. H. Junod.

DROMICA (COSMEMA) zuluana, n. sp.

Fusco-cuprea, sub-nitida, lateribus prothoracis elytrorumque sub-æneis, antennarum articulis quatuor basalibus, tibiis, femorumque basi rufo-flavescentibus; labro flavo, haud fuscomarginato; capite lato, inter oculos valde plicato, collo transversim plicato-scabroso; prothorace breve, latitudine longiore, basi apice angustiore, ad basim haud sensim strangulato, areis dorsalibus duabus modice convexis, transversim undulato plicatis prædito; elytris elongatis, ad medium modice ampliatis, convexis, apice haud singulatim emarginatis, spina suturali brevi acuta munitis, punctis profundis confertis, ad latera obliteratis, in partem anticam remotius positis obsitis, macula supra-marginali sub-elongata flava, vittaque marginali breve apicis spinam attingente utrinque notatis. This species is allied to D. elegantula and also to D. cordicollis, but it is easily distinguished from both these species by the entirely flavous labrum, the sub-cylindrical prothorax, which is slightly attenuated in the posterior part and very little constricted there, and the much more closely set punctures which are also less wide, and which, instead of being of a uniform size as in the two species mentioned above, are slightly broader in the anterior than in the posterior part; in my examples of D. elegantula and D. cordicollis, the sides of the elytra are punctured as far as the outer margin, whereas they are broadly impunctate in D. zuluana.

Length 11 mm.; width 34 mm.

Hab. Natal (Eshowe).

FAMILY CARABIDÆ.

TRIBE ODOCANTHINI.

GEN. CASNONIA, Latr.

CASNONIA LÆTA, n. sp.

Rufo vel pallide rufo testacea, capite nigro, elytris fascia media communi lata, ad latera postice ducta læte cærulea, antennis fuscis articulis quatuor basalibus rufo testaceis, pedibus etiam fuscis femorum basi rufescentibus; abdomine nigro; palpis infuscatis; caput impunctatum; prothorax tenui, valde elongatus, post medium leviter ampliatus, ad basim strangulatus, convexiusculus, tenuissime longitudinaliter in medio canaliculatus, haud distincte transversim plicatulus, setis longis flavescentibus obsitus; elytra a basi apice punctis setam rigidam ferentibus seriatis prædita.

This species is evidently closely allied to C. senegalensis in shape and colouring, but it differs by the series of rigid setæ which are found on the prothorax and on the elytra, and which are wanting in the former, in which all the joints of antennæ are red; the prothorax is transversely plicate.

Length 7-8 mm.; width 1-2 mm.

Hab. Natal (Malvern), C. N. Barker. Southern Rhodesia (Sebakwe), Delancey Dods.

TRIBE LEBIINI.

GEN. LEBIA, Latr.

LEBIA PROMONTORII, n. sp.

Flavo testacea, elytris pedibusque pallidioribus, illis plaga suturali communi nigra, pone medium quadrata striam 4 utroque attingente, antice valde acuminata, ad scutelli apicem ducta, postice angustata, truncata, longe ante apicem desinente notata; antennarum articulis longe pubescentibus; capite impunctato; prothorace brevi, longitudine tertio latiore, medio sulcato, lateraliter antice ampliato rotundato, postice fere recto angulis acutis reflexis, disco levi; elytris basi prothorace tertio latioribus, pone medium ampliatis,

supra vix convexis, punctulato striatis, interstitiis planis, vage aciculatis; abdomine sub-infuscato.

This species differs from all the other South African species by its impunctate upper side and the great ampliation of the posterior part of the elytra; the shape of the black patch on the elytra is not unlike that of L. imitator, but it reaches the scutellum in L. promontorii, which it does not in the former which has also the head black.

Length 5 mm.; width 23 mm.
Hab. Cape Town. A. Raffray.

LEBIA SEBAKUANA, n. sp.

Pallide testacea, glabra, capite nigro, antennis prothoraceque rufo-testaceis; elytris fascia communi nigra basi quadrata ibidem striam attingente, deinde angustata, pone medium modice dilatata, plaga laterali utrinque a fascia communi late interrupta notatis ; capite crebre aciculato, lateribus strigillatis; prothorace ampliato, longitudine tertio latiore, antice lateraliter ampliato rotundato, postice distincte sinuato angulis acutis, reflexis, medio canaliculato, disco distincte aciculato; elytris a medio ad apicem perparum ampliatis, nonnihil convexis, punctato striatis, interstitiis convexis, creberrime aciculatis.

The South African species to which this species might be compared owing to the head being black, and also to the shape of the dorsal markings, is L. vaciva, Pér., which is, however, densely pubescent, quite differently sculptured, and much larger.

Length 4 mm.; width 13 mm.

Hab. Southern Rhodesia (Sebakwe). Delancey Dods.

LEBIA TENELLA, n. spec.

Glabra, capite prothoraceque rufo-flavis; elytris subtusque stramineis, illis fascia communi nigra basi-quadrata striam 4 attingente, deinde angustata, pone medium ad marginem lateralem utrinque extensa, longe ante apicem desinente ornatis; abdominis segmentis duobus ultimis infuscatis; capite antice aciculato, lateraliter conspicue plicato; prothorace antice ampliato rotundato, deinde fere recto, angulis posticis acutis, reflexis, medio canaliculato, disco crebre aciculato; elytris a medio ad apicem perparum ampliatis, haud convexis, punctulato striatis, interstitiis planis, tenuissime creberrimeque aciculatis.

One of the smallest of the South African species; the livery resembles that of L. fortuita and of L. natalensis, but the lateral
