from San Bernardino, Paraguay (Fiebrig), and one male from 

 Yahuarmayo, Peru (Townsend). In the male the two abdominal 

 bands extend down the sides to the margins of the tergites. 

 I add a third species with key to all three. 



KBY TO SPECIES OF EiUANTHA 



1. Fourth vein with long appendage at bend ; pollinose bands of second and 



third abdominal segments not interrupted in middle 2 



Fourth vein without appendage at bend or with a mere trace of one ; abdomi- 

 nal pollinose bands interrupted in middle interrupta, new species. 



2. Wing blackish without yellow region ; male with black femora and abdomen. 



Female with abdominal bands not extending down the sides. 



aucta Wiedemann. 

 Wing blackish apieally, broadly yellow in middle; male with yellow femora 

 and most of second and third abdominal segments reddish; female with 

 abdominal bands extending down the sides {dives Wiedemann).

 EUANTHA INTERRUPTA, new species 



The male is similar in appearance to the two known species, but 

 the yellow blotch in the wing is more squarely cut off just beyond 

 the small cross vein, and the abdomen does not show the red ground 

 color which is prominent in liturata. The abdominal bands are nar- 

 rowly but distinctly interrupted in the middle line. 



The female has quite black wings, with the discal cell nearly to its 

 tip whitish, strongly contrasting. The abdominal bands are narrow 

 and widely interrupted. It is much easier to pick the females as a 

 distinct species than the males. The front of the female is indis- 

 tinctly shining or very thinly pollinose along the middle stripe. 



Legs black in both sexes. 



Length of male, 11.2 to 13.6 mm. ; of females, 9.2 to 11.8 mm. 



Described from four males and three females. Collected at 

 Higuito, San Mateo, Costa Kico, by Pablo Schild. One specimen is 

 dated August 6, 1914.

Dexia eques Wiedemann, Auss. Zweifl., vol. 2, 1830, p. 378. 

 Pseudodexla eques Beauee and Bergenstamm, Denk. Wien. Akad. Wiss., 

 vol. 58, 1891, pp. 372, 378 ; vol. 60, 1893, p. 131. 



One male, labeled "Bahia" "eques Wd. Coll. Winthem." Un- 

 doubtedly type of the species eques, which is the genotype of Pseudo- 

 dexla. Agrees exactly with Wiedemann's description; the specimen 

 is characterized by a very peculiar wing, reproduced in Figure 3, 

 which has been carefully drawn by C. T. Greene. The apical half of 

 the wing is remarkably elongated, and there is a marked although
