clypeal grooves evident; antennae with second segment about one 

 and one-half times as long as first segment, both segments somewhat 

 flattened. Pronotum broad, short, nearly four times as broad as long. 

 Mesonotum strongly produced anteriorly; costal margins of the wing 

 faintly crenulate; costal membrane about twice as broad as the 

 costal 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, 

 triangular, barely exceeding the pygofers; last ventral segment of 

 the male broader than long, roundly excavated apically; pygofers 

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

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

 subapically, 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 numerous large and small spots and the last subapical 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 Flatoides 

 punctatus Walker but they are much more heavily spotted and their 

 genitalia are entirely different.

The original description is here quoted. 

 This species may be recognized by its small size, pale 

 color and short transverse vertex. 



Head broad, nearly as broad as the disk of the pronotum; vertex 

 short, about one and one-half times as broad as long; anterior margin
