SPONGILLA-FLIES — PARFIN AND GURNET 509 



It is one of two species studied thus far possessing the transverse 

 radioniedial streak. It can be separated from carpenteri from Para- 

 guay, the other species, by the radioniedial streak, which is obhquely 

 du'ected distad and of ahnost even length to MP, and the heavy setal 

 spotting. The lateroventral halves of the ninth tergite in the female 

 appear to resemble those of basalis and carpenteri most closely, but 

 those of bimaculata are longer in comparison with the width. How- 

 ever, the hindwings are almost alike, with the holotype of bimaculata 

 showing no radial cross-vein between R2 + 3 and R4-f5 in either 

 hindwing (possibly variable).

Female (holotype) : Head with vertex medium brown ; face yellow- 

 ish; palpi yellow; basal two antennal segments light brown, following 

 segments dark brown for approximately two-thirds of length, inter- 

 grading into brownish yellow for slightly more than one-half of 

 remaining third, the apical segments light brown; legs yellow with 

 faint brownish shading on mesothoracic and metathoracic coxae; 

 pronotum yellowish dorsally with reddish and blackish brown streak- 

 ing, mesonotum and metanotum brownish yellow, mesothoracic and

 yellowish except for dark brown streaking along inner margin basally 

 in the space from slightly posterior to 1st A to slightly anterior of 2d A

 from Cul branches to base dark brown, broadest at base; slight indica- 

 tion of faint bro\imLish intervenational streaking between longitudinal 

 medial veins distally from outer gradates to margin; pterostigma 

 yellowish; longitudinal veins yellow basally, light brown distally, both 

 inner and outer gradates dark brown with outer gradates except for 

 3d r and 3d m-cu bordered, 2d r of inner gradates also faintly bordered,
