a broad band (7-8 joints) shortly beyond the middle, clear 

 white. Face, clypeus, mandibles and palpi, yellowish- 

 white ; the front and vertex black, except for a yellow line 

 along the orbits ; and the outer orbits, except above, 

 yellow. The face is strongly punctured, broadly rounded 

 in the middle, thickly covered with white hair ; the 

 clypeus roundly projecting, smooth. Thorax black ; the 

 scutellum broadly at the base, the post-scutellum, the 

 sides of the median segment on the oblique apical part,, 

 the base of the pronotum, the tubercles, a mark on the 

 apex of the mesopleura.-, obliquely truncated behind a 

 a large curved mark, obliquely truncated at the apex on 

 the base of the metapleura;, and a mark immediately 

 under the hinder wings, yellow ; the middle lobe of the 

 mesonotum raised, clearly separated from the lateral at 

 the apex and sides, the depression at its apex being large. 

 Scutellum and post-scutellum smooth. The median seg- 

 ment behind the transverse keel is smooth ; the rest of it 

 to the apex strongly transversely striated ; the striae finer 

 and closer on the basal region. The pronotum raised, 

 tuberculated at the base on the yellow part ; the upper 

 part has some scattered shallow punctures ; the middle 

 longitudinally striolated, the base not quite so strongly 

 perpendicularly striated, the rest smooth. On the meso- 

 pleurai, the tubercles, and the middle and the lower part 

 behind are smooth, the rest striated ; there is a curved 

 furrow on the lower part next the sternum. The 

 metapleurie are rugosely punctured, thickly covered with 

 long pale fulvous hair ; at the apex before the hinder 

 coxaj is a yellow tubercle-like mark. The mesosternum 

 is obliquely truncated at the base and apex where it is 

 smooth ; the central part punctured, with a crenulated 

 furrow ; the base keeled. Legs fulvous, the coxa^ and 

 trochanters white, the hinder coxai white, broadly black
