hyaline; sides of sternum maculated with flavescent; legs yellow, hind tibiæ without any spur.

Length of body 20 mm., of fore wings expanded 44 mm. of hind wings 35 mm.

SUB-FAMILY NEMOPTERIDES.

GEN. NEMOPTERA, Latr.

NEMOPTERA PURCELLI, n. sp.
Plate IX., fig. 13.

3. Head, thorax, and abdomen bright drab colour, sides of thorax and legs pale yellow; antennæ moderately long, sub-infuscate; head trituberculate on the vertex and with two small, not very distinct tubercles close to the base of antennæ; pronotum very strongly constricted with the anterior margin highly reflexed and fringed with upright fairly long bristles; mesonotum plurigibbose and bearing a few setose hairs laterally; abdomen short; anterior wings sub-obtuse at tip, hyaline with a slightly fuscous venation; the radial and sub-costal nervures and the space between them pale flavescent, the hind border and also the nervures are fimbriate; hind wings very long, very narrow, broadly dilated at apex in a very broad ovate paddle-like expansion half twisted in the centre, light fulvous like the stalk itself, which is lacteous, however, above the dilatation, and acuminate and distinctly lacteous at apex.

In the figure the white tapering lacteous part of the hind wing has not come out well; the right wing, however, shows the half twist of the paddle.

Length of body 10 mm. ; expansion of anterior wings 35 mm.; length of posterior wing, 29 mm.

This remarkable species was discovered some twenty-six years ago at Constantia, near Cape Town by my colleague, Dr. W. F. Purcell. It has not been met anew,

NEMOPTERA PULCHELLA.
Plate IX., fig. 14.

?. Body and antennæ light fulvous, legs pale flavescent; vertex of head plainly trituberculate, thorax concolorous, pronotum constricted, and with the anterior margin and the sides densely setose;

sutures of the mesonotum very deep, the latter almost bigibbose; abdomen short; anterior wing long, slightly acuminate at apex, hyaline with a very slight pinkish tinge, the sub-costal costules greenish yellow for the whole of the length, no pterostigmatic macule, the reticulation nearly translucent; hind wings very long, pale greenish yellow, and ending at apex in a long, broad oar-like pinkish dilatation having a half twist.

In the figure this dilatation had to be shown flat.

Twice only did I meet with this pretty, delicate-looking insect, and I was not fortunate in the second occasion to capture the specimen.

Length of body 9 mm.; expansion of fore wings 42 mm.; length of hind wing 37 mm.

NEMOPTERA DUMBRODIANA, n. sp.

3. Flavescent, but with the upper part of the head, of the thorax, and the whole abdomen very light buff; basal joint of antennæ also buff-the other joints are missing; vertex of head with a conspicuous median tubercle; no traces of a neck; mesonotum constricted, short, sparsely setulose laterally, gibbosities of the mesonotum greatly developed; abdomen twice the length of the head and thorax taken together, the segments plainly pubescent; anterior wings moderately acuminate rounded towards the median part of the apex, hyaline but with the venation, especially the subradial nervures, which are set very closely to each other and become united slightly past the middle, somewhat flavescent; no pterostigma; the hind wings are very narrow, very long, and ampliated at about two-thirds of their length into a narrow, oar-blade like process, making half a twist, very little acuminate at apex; for two-thirds of the length the hind wing is flavescent fuscous, turns thence to whitish for one-sixth of the length, the dilated reniform part is plainly fuscous for two-thirds of its length, but has an elongated lacteous patch along the upper edge, the third hind part is lacteous, but the very apex is lightly infuscate.

Length 15 mm.; expansion of fore wings 48 mm.; length of hind wing 54 mm.

Not unlike in general appearance, and especially in the shape of the hind wings, N. africana, but the fore wings are more rounded in the anterior apical part and less distinctly acuminate on this account, the two sub-radial nervures become united slightly past the middle instead of at about four-fifths of the length as in the N.

africana, and lastly the colouration of the narrowly expanded reniform part of the hind wings is different.

GEN. CROCE, McLachl.

CROCE LIGHTFOOTI, n. sp.

Body very light drab; no yellow markings anywhere. Rostral part of head very long, antennæ wanting in my three examples, but from memory I can state that they are not long; pronotum longer than broad, attenuate in front but not constricted there and with only a few, very small setæ laterally; mesonotum distinctly plurigibbose; abdomen twice as long as the thorax (3), concolorous; anterior wings hyaline and strongly iridescent, narrow at base, moderately acuminate at apex, plainly fimbriate all round, and with all the nervules distinctly hairy, and light drab in colour; pterostigma very long, partly white partly brown but not very conspicuous, costal space narrow, divided by not numerous nervules; hind wings very long, thread-like, slightly more than three times the length of the body, greatly diverging, slightly tapering towards the apex, clothed with a dense short pubescence, and having at about one-third of their length an elongated bunch of silky lanuginose white hairs, occasionally mixed with a few drab ones; the colour of these hind wings is light drab from the base to about the median part, and thence white.

The lanuginose bunch varies in size; it is never very large, but it is quite distinct. This character distinguishes it from C. damara, McLach., which I know, however, from description only, but in which the pubescence of the nervules of the wings is not mentioned.

Length of body 91-93 mm. ; expansion of wings 24-25 mm. ; length of hind wing 35-41 mm.
