Testaceous, densely punctured ; median carina nearly obsolete ; a 

 broad, diagonal stripe on each side behind humeral sinus, lateral bord- 

 ers from sinus posteriorly, and a spot on each tegmen in front of 

 middle, yellow; sides of chest, and sometimes spots on posterior pro- 

 cess of prothorax, tarsi, costa, two longitudinal veins, and veins- sur- 

 rounding fourth apical area, ferruginous ; basal half of costal and 

 interior basal areas, and large part of apex of tegmina, fuliginous. 



Long. /, lat. inter hum. ang. 3 mm. 



Described from four females ; types in Uruguayan Na- 

 tional collection and in collection F. W. G. 



Hob. Uruguay. 



The fourth and fifth apical areas united equal width of the 

 broad interior basal area ; whereas, in maura Fab., the only 

 other member of the genus, the same space is occupied by the 

 fifth area alone; also the third apical area is not small, as in 

 maura, but is of the usual size and rather long and narrow. 



The examples in the Uruguayan National collection are la- 

 beled "Darnis amargosi Berg," which doubtless is a manu- 

 script name as no description seems to have been published. 

 It feeds on Syringium sp. in February. 



Pupa. There is in the Uruguayan collection one example of 

 the pupa of this species, badly mutilated, the body missing; 

 but, as descriptions of pupae of this family are rarely pub- 

 lished, the following has been prepared. 



Testaceous, mottled with ferruginous, pubescent ; head similar to 

 the mature insect, but more rugose ; prothorax dome-like, deeply ex- 

 cavated at base in the middle, on each disc of which it has several black 

 spots ; dorsum highly elevated and rugose, with a deep impression on 

 each side in front ; posterior edge extending towards the summit, on 

 each side, suddenly extending backward in a triangular shape, on the 

 top with three large longitudinal fuscous marks ; the apex of the tri- 

 angle nearly reaches the base of abdomen ; at the summit is a crest- 

 like foliation resembling a cock's comb, red, extending forward ; the 

 metathorax is exposed behind the posterior border of the prothorax. 

 The wing pads are strong, flat, and joined together, over the abdomen, 

 by a broad flat membrane. Abdomen is exposed, along its median
