Three males, Cuernavaca, Mexico, June and July, 1906 (W. Schaus). 



Type.— Cat. No. 10338, U.S.N.M. 



Allied to diversa Druce and laranda Schaus, but both of these have 

 rounded discal marks, and the shape of the silvery lines is different. 



VIPSANIA ANTICLEA Druce. 



2T(de. — Agrees entirely in coloration with the female figured in the 

 Biologia Centrali-Americana, except that the hind wings are pale 

 instead of blackish. There is a marked difference in palpal structure 

 betw^een the sexes. In the female they are nearly porrect, the second 

 joint being long and only very slightly curved; the end joint is stout 

 and thick, square on the tip, thickened by the vestiture. In the single 

 male before me the palpi have the second joint strongly curved, so 

 that they stand upright, the third joint long but with a sharply tapered 

 tip. The palpi are not over twice as long as the head, reaching not 

 far above the vertex, whereas in the female they are three times as 

 long as the head. The hind tibia^ have two pairs of spurs. The 

 antennae are simple. 



This genus was placed by me between Mlresa and E'pidea^'- on the 

 supposition that the male antennee were pectinated to the tip. This 

 proves to have been an erroneous assumption, the genus properly 

 falling between Vipsophohetron and Pseudovipsania. It differs gener- 

 ically from the latter in having the middle spurs of the hind tibias 

 present, and falls in the table with L'dhacodes., from which it \naj be 

 separated by the wing shape, sunken head, and palpal structure. 



There is a possibility that this is not the male of V/psania anticlea 

 Druce, in which case it is a new species, but the markings and colora- 

 tion are so exactly alike that 1 think the association is warranted, in 

 spite of the different palpal structure in the two sexes. The single 

 specimen is from Oiernavaca, Mexico. 



EUPROSTERNA COCHLIDIONIS, new species. 



Brownish ocherous, the fore wings sprinkled with brownish atoms; 

 basal half darker brownish; a narrow dusky blackish line starts on 

 costa at apical fourth, runs obliquely inward to submedian vein, runs 

 along that vein halfway to base, and is then continued straight to inner 

 margin at basal third; another line starts from the costa at the same, 

 or nearly the same, point and runs obliquely to the outer margin above 

 tornus. Hind wings pale brownish straw color. Expanse, 17 to 

 19 mm. 



Two males, Cuernavaca, Mexico and Iguala, Guerrero, Mexico, 

 June, 1906 (W. Schaus).
