160 DIPTEEA. 



I have seen specimens in the Museum in Cambridge, Mass., and in Prof. Bellardi's 

 collection.

Specimens are contained in the Oxford Museum, in Cambridge, Mass., and in Prof. 

 Bellardi's collection. 



LEPIDOPHORA. 



Lepidophora, Westwood, London and Edinb. Phil. Mag. 1835. 



The known species, to one of which I provisionally refer the Central-American 

 representative before me, of this New- World genus may (from the descriptions) be 

 grouped as follows : — 



Wings uniformly brown. 



Abdomen with spots of yellow scales ; second submarginal cell 



without stump of a vein lepidocera,Wiedem. (N. Amer.). 



(Synon. eegeriiformis, Westw.) 

 Abdomen with spots of white scales ; second submarginal cell 



with a stump of a vein appendiculata, Macq. (Texas) . 



Wings hyaline or subhyaline at the apex vetusta, Walk. (Amazon E.) . 



secutor, Walk. (Amazon R.) . 

 Wings brown along the anterior margin only culiciformis, Walk. (Para). 



l. Lepidophora vetusta? 



Lepidophora vetusta, Walker, Trans. Ent. Soc. Lond. 1857, p. 145 1 . 



Eab. Mexico (SalU), Ventanas (Forrer) ; Guatemala, El Keposo 800 feet (Champion). 

 — Amazons 1 . 



I doubtfully refer to this species the very much abraded specimens from Ventanas 

 and El Reposo. They differ from Walker's description in having the curved veins 

 in the apical portion of the wings more or less clouded with brown, and for this reason 

 I took them at first for a different species. The specimens in Prof. Bellardi's collection, 

 however, have the wings as Walker describes them : the apex hyaline, including the 

 expanded end of the marginal cell ; the posterior cells (2, 3, 4) and the anal cells also 

 hyaline. This coloration is not, however, constant: in one of the specimens in 

 Bellardi's collection the expanded end of the marginal cell is filled out with brown ; the 

 same is the case with the specimens from Ventanas, &c, and there is no reason for not 

 regarding them as the same species. Walker's "femora partly ferruginous" might 

 apply to the sometimes reddish-brown femora, especially in old specimens. The type 

 in the British Museum is a single, very much abraded example.
