cell ; the transverse veins slightly reticulate ; humeral angles not much 

 produced ; hind tibia with three spines ; the basilar one small ; female 

 genitalia with last and penultimate segments deeply almost squarely 

 excavated; pygofers large, broadly curved on the inner margins; 

 marginal teeth very fine and numerous ; anal segment broad, tri- 

 angular, barely exceeding the pygofers ; last ventral segment of the 

 male broader than long, roundly excavated apically; pygofers nar- 

 row, about two and one-half times as long as broad, longer than the 

 last ventral segment, broadly separated at the base, approximate sub- 

 apically, their apices bluntly rounded. 



Color : General color in the female pale ochraceous buff, heavily 

 flecked with blackish fuscous; in the male the general color is more 

 olive ; head unmarked except for two blackish dashes in front of the 

 eyes, and three black spots on the second joint of the antennae. Pro- 

 notum with two impressed points near the anterior border and a 

 blackish cloud behind the eye. Mesonotum with three blackish spots 

 along each posterior border, the central one very large and a pair of 

 spots medianly near the anterior border ; wings heavily marked with 

 irregular blackish fuscous spots. There is usually a row of very 

 irregular spots along the costal border which become small triangular 

 spots around the apical margin. The corium is marked with numer- 

 ous large and small spots and the last sub apical line is irregularly 

 bordered with fuscous externally ; the clavus has a large spot near the 

 base and a row of short dashes along the sutural margin. 



Length, female, apex of head to apex of abdomen 7.50 mm. ; to 

 apex of wing 10.40 mm. ; male, apex of head to apex of abdomen 6.30 

 mm. ; to apex of wing 9.20 mm. 



This species might be confused with pale specimen of Flatoidci 

 pimctatus Walker but they are much more heavily sjiotted and their 

 genitalia are entirely different.
