EEIOPTERA. 159 



genitals reddish-yellow ; halteres yellow ; feet pale yellow ; the 

 femora of some specimens are pale yellow, with a brown band 

 before the tip ; in other specimens they are dark brown, with a 

 pale band ; wings yellowish ; a narrow brown band runs along 

 the central cross-veins, and generally does not go beyond the 

 great cross-vein ; sometimes, however, it is connected with a 

 cloud at the end of the anal cell ; small brown clouds at the tip 

 of all the veins (except the third), on the subcostal and the discal 

 cross-veins, at the origin of the prsefurca, and the inner end of 

 the third posterior cell ; the middle portion of the fifth longi- 

 tudinal vein infuscated and surrounded by a more or less extended 

 cloud, which sometimes expands so as to coalesce with the spots 

 at the origin of the prjefurca and at the tip of the seventh vein, 

 and forms a band not unlike the inner band of E. venusta.

This species is in all respects similar to E. venusta, only the 

 brown picture of the wings is less extended. If we imagine some 

 of the spots more expanded, two bands, perfectly similar in shape 

 to those of E. venusta will be formed. Still, although I have 

 seen numerous specimens of E. venusta, I found its picture rather 

 constant, and I have not observed any specimens with brown 

 femora, as they occur in E. armillaris. The following species — 

 E. graphica — shows also the most striking analogy to E. armil- 

 laris in the distribution of the spots on the wings ; only the body 

 as well as the wings is a shade darker brown. If E. graphica 

 did not exist, I would feel less hesitation about uniting E. armil- 

 laris and venusta; but E. graphica is, to all appearances, nothing 

 but a dark colored E. armillaris, and anybody w^ould hesitate to 

 consider graphica and venusta as the same species. I invite the 

 attention of collectors to these three species.

 along the posterior margin. Long. corp. 0.25 — 0.27.
