the surface divided into three almost equal parts l)v a longi- 

 tudinal sulca on each aide. Median segment broad, sub- 

 quadrate, ojily slightly narrowed posterior!}', abruptly truncate, 

 the an<;les above the truncation produced on each side into a 

 minute sj)ine, the dorsal surface of the seo^nient coarsely 

 rugose, the surface of the truncation irregularly obliquely 

 striate. Abdomen shining ; the three basal segments large, 

 the second slightly constiictcd at the base; sparsely punc- 

 tured, the sides of the segments (especially of the third) very 

 finely and closely punctured; the apical segments small and 

 withdrawn. 'J'he tibia? are smooth, not serrate. The inter- 

 mediate tibia; have two apical spines. 



Black* ; a spot beneath the scajie of the antenna3 at the 

 apex pale yellow ; abdomen dark fuscous. "Wings hyaline, 

 slightly tinted with yellow, the radial and second and third 

 cubital cells clouded with pale fuscous. Tegula? and nervures 

 testaceous. 



The first recurrent nervure is received close to the apex 

 of the first cubital cell, the second just at the base of the 

 third cubital cell, almost interstitial with the second trans- 

 verse cubital nervure. The second cubital cell is veiy 

 narrow on the radial nervure; the first transverse cubital 

 nervure is bent sharply outwards near the base.

 punctured ; head opaque, the front strongly sculptured 

 irregularly longitudinally punctured striate, vertex reticulate. 

 Pronotum suLquadrate, about half the width of the nieso- 

 notum, very coarsely rugose, with an obscure indication of a 

 median sulca; a small tubercle on each side before the 

 posterior angle, behind the tubercles the pronotum is obliquely 

 depressed to the posterior margin. Mesonotum and scute Hum 

 very coarsely lugose, the mesonotum reaching to the hind 

 margin of the tegular, the scutellum broadly rounded at the 

 apex. Median segment at the base as broad as long, flat 

 above, truncate posteriorly, the lateral margins raised, the 

 dorsal surface strongly longitudinally striate, the striie about
