Under " Var y" Walker has perhaps included specimens of Enyo 

 dannm. 



This species differs from the following by the stronger, posteriorly 

 better-defined, blackish terminal shade : by the absence of a darker 

 shade on the second basal segment above, by the non-excavation of the 

 apical interspace on external margin, and by its generally larger and 

 stouter size. Two specimens S and $ . Exp. % and § 2.50 inch. Length 

 of body S , 1.40, 9 1.30 inch.

The specimens correspond, as well as usually the case, with Cra- 

 mer's figure. Since I do not see any difference in the squammation of 

 the " legs" between this and the foregoing species, I do not quote Dr. 

 Clemens' description here. The color is generally more brownish than 

 that of E. lugubris^ the apical interspace is excavated, the semi-luni- 

 form paler shade which extends from apex to second median nervuk- 

 is larger ; the oblique median even line is followed by a broad darker 

 diffuse shade continued very nearly to internal margin, beyond this the 

 first of the tremulous transverse lines is somewhat more projected su- 

 periorly ; the external margin is less abruptly excavate below the sub- 

 costo post-apical nervule. The coloration is generally paler, less black- 

 ish, and the insect is smaller; anal angle of posterior wings less pro-
