II. Nonacris Walk. Ins. Saund. 7 (N. transequa, S. Ainerica) is 

 reprcsented in the Brit. Mus. by a single male, which, to all appearances, 

 is a male Chiromyza; I could not discover any difference. 



III. Inopus Walk. Ins. Saund. 2, Tab. 1, f. 7 (I. despectus, sine 

 patria). The type in the Brit. Mus. (a single male, very much darnaged) 

 has no machrochaetae, nor spurs on the bind libiac, bolli characters 

 applicable to Chiromyza; the venation is like that of Chiromyza; bat 

 the body is uiore slender, and the antcnnae, as represented in the figure 

 are not those of Chiromyza (they are broken in the type-specimen). 

 The question therefore about this genus remains in suspense until more 

 specimens, and in better preservation, are produced for examination. 



IV. Lampromyia Macq. and JLeptynonia Westw. Trans. Ent. 

 Soc. 1876, p. 517, Tab. VI, f. 7. T owe to the kindness of Prof. 

 Westwood the opportunity to examine the typical specimens of Lepty- 

 noma sericea (South Africa) in the Oxford Museum. It has two pulviili, 

 the third being rudimentary; the supernumerary crossvein in the marginal 

 cell, which the figure shows, proved upon close examination to be 

 merely a darkcr shade in the brown spot upon which it is placed in 

 the figure; these are the two principal difFerences which prevented the 

 Identification of this genus with Lampromyia Macq. A few remarks 

 about the latter genus may not be amiss here. 



Lampromyia has no macrochaetae: the legs are smooth, except 

 some very minute, almost microscopic bristles ou the tibiae; front tibiae 

 with a Single spur, the others with two; two pulviili. Face and front 

 show very little difference in breadth in both sexes, the eyes not being 

 contiguous in the male, as they are in most Leptidae. The abdomen 

 is not tapering in the female, as other Leptidae have it; it is only a 

 little broader on the proximal half than that of the male and ends 

 obtusely. The male genitals show a singular horny armature, consisting 

 of a subglobular body, with a kind of concave lid over it, in the shape 

 of an inverted half-cylinder; within the hoUow of the latter, when seen 

 from below, a pair of palpi-like organs are visible, which probably 

 represented the forceps. Altogether, with its long proboscis, Lampromyia 

 is a very singular insect. 



Macquart, who at first (Hist. Nat. Dip. II, 660) referred Lampromyia 

 to the Bombylidae, corrected himself afterwards, (D. E. II, 1, 29) and 

 poiuted out its relationship to Verniileo. The same view was taken 

 by Schiner and is no doubt the true one. Four species are described 

 now: cylindrica Fab. (Syn. funebris Duf.), pallida Macq., canariensis 

 Macq. and sericea Westw. (Leptynoma). About canariensis Macquavt
