Genus VIII.— SCHIZOCERUS, Latreille. 



AntenncE 3-jointed, 2 basal joints short, 3rd elongate, furcate, with numerous 

 series of rigid hairs on each branch ; in the female simple, filiform and 

 naked : mandibles unidentate : head transverse, with a frontal tubercle : 

 ocelli 3 : wings ample, anterior with 1 perfect marginal areolet, and 3 im- 

 perfect nearly equal submarginal ones, the former with its nervure carried 

 to the apex : abdomen rather short : legs simple ; tibia with spines only at 

 the apex. 



Both sexes of the insects of this genus may be known from 

 Hylotoma by having the marginal areolet of the anterior wings 

 complete, and not partially divided by a nervure, in addition to their 

 having the 4 hinder tibiae not armed with a spur towards the middle 

 of the inner margin, and other differences in the trophi : the males 

 have a peculiarity in their antennae, which are singularly furcate, the 

 loxig terminal joint being divided into two long branches of equal 

 length, which are strongly ciliated on both sides : in the females this 

 joint is simple and filiform. 



Sp. 1. furcatus. Niger, abdomine Jlavo, segmento V-mo nigricante, pedibus 

 palpisque luteis. (Long. corp.2|— 3^ lin. ; Exp. Alar. 6 — 7^ lin.)
