 FIOUBB 8 



Description. — Winged adult: Head dark castaneous-brown, with 

 fairly dense short hairs and longer bristles. Eyes black, nearly 



round, separated from lateral 

 margin of head by a distance 

 less than their diameter. 

 Ocelli white, fairly large, oval, 

 separated from eyes by a dis- 

 tance less than the long di- 

 ameter of an ocellus. Fon- 

 tanelle not visible, or a raised 

 white spot at the convergence 

 of two lines from the ocelli to 

 apex of head, or the outlines 

 of the epicranial suture. Post- 

 clypeus lighter colored than 

 head, raised up, with a me- 

 dian line, about twice as broad 

 as long — broader than in heinii

 segments, third segment 

 smaller than fourth, second as 

 long as third and fourth.

 straight. Mesonotum and 

 metanotum slightly emargi- 

 nateposteriorly, Wingssmoky 

 gray, margins white, tissue 

 densely punctate, and with 

 fairly dense hairs. In fore wing, median vein closer to cubitus than 

 to subcosta, branched to apex ; cubitus with 10 branches to lower mar- 

 gin, 8 of which are thickened. Tibiae yellow-brown. Abdomen 

 lighter colored than head, with dense hairs and a row of longer 

 bristles at the base of each tergite.
