EANTIS. 



Eantis, Boisduval, Sp. G<5n. Atlas, t. 13. f. 6 (1836) ; Wats. P. Z. S. 1893, p. 57. 



We use this genus in a rather more restricted sense than Mr. Watson, who placed 

 in it Mr. Butlers Achlyodes rosina, A. gorgophone, and Felder's Helios meoricana, a 

 distinct form, as will be seen under the next genus. This leaves us E. busirus, 

 E. thraso, and E. pallida of our region, which agree in some points, but differ in others, 

 so that even now Eantis is a heterogenous group. 



The type E. husirus has the primaries slightly falcate, the outer margin very convex 

 in the middle and concave towards the apex. The cell is long and narrow, the third 

 median segment about half the length of the second segment ; the lower and middle 

 1 discocellulars are feeble, oblique, and subequal, the latter bent in the middle; the 

 secondaries have very feeble discocellulars, the radial hardly visible, the third median 

 segment is short but distinct, rather shorter than the second subcostal segment ; the 

 secondaries in the male have a tuft of black hairs near the base of the costa on the 

 upperside, and a black scaly patch adjoining, on the underside of the primaries at the 

 base of the inner margin is a corresponding tuft and scaly patch. The palpi have a 

 ' very short terminal joint just appearing beyond the clothing of the second joint ; the 

 hind tibiee of the male have two pairs of spurs and a well-developed tuft. 



In E. thraso the margin of the secondaries is more regularly rounded, and there 

 are no tufts on the wings at their bases ; the radial of the secondaries is stronger, 

 and the lower discocellular rather the longer of the two, the third median segment 

 being very short. In E. pallida the outer edge of the primaries is evenly convex 

 throughout from the apex to the anal angle, the palpi are more prominently porrect, 

 the secondaries being much as in E. thraso. 



E. busirus and E. thraso have a very wide range in tropical America, the range of 

 E. pallida being more restricted to the western portion of the continent, Central 

 America, and Mexico.
