38 ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 



Hymenitis andreas A. G. Weeks, Jr. * 



(Plate VI, Figure 4.} 

 Habitat: Bolivia. Expanse: 1.90 inches. 



Head black, with four white specks on collar. Also a white speck at 

 each eye and two others at junction of each antennae. Thorax and abdomen 

 above nearly black; below nearly white. Antennae black. Legs black, grey- 

 ish underneath. 



Fore wing transparent with a greenish blue lustre, as is prevalent in species 

 of this genus. The inner marginal area is black. The costa is black, 

 and at end of discoidal space the black extends downwards to a point at 

 lower end of discoidal space, this black triangle being nearly a quarter 

 inch wide on its costal edge. Outside of this is a band of white scales 

 running from costa downwards across end of discoidal space and termin- 

 ating next to the lowest submedian nervule. The black of the costa 

 broadens to a sixteenth inch in width outside the white band, turning at apex 

 and continuing downwards along hind margin and joining the black of the 

 inner marginal area at lower angle. At the lower angle, in interspace above 

 the lowest submedian nervule, there is a mere suggestion of a dash of white 

 scales. The nervules are all black. 



Upper side of hind wing transparent, with lustre as above noted. Costal 

 area black. Hind margin with a black border one-sixteenth inch wide, les- 

 sening and dwindling to a thread towards submedian nervure. At apical angle 

 there is a very slight light brownish dot. 



The under side of fore wing is identical with upper surface except that the 

 black portions are reddish brown bordered by a darkish thread. The inner 

 marginal area, however, is black. There is also a suggestion of three inter- 

 spacial white dots at apex. 



Under side of hind wing is the same as upper surface, except that the 

 black portions are reddish brown bordered on the basal side by a black 

 thread. The hind margin, also, has a black thread at its edge. The brown 

 spot at upper angle on fore wing is white on the under surface. 



Described from seventeen specimens taken September 12, 

 1899. A duplicate has been found in a European collection, 

 taken also in Bolivia, but unnamed.
