 obscure yellow. Mandibles with a yellowish tinge at the base, the

 the scutellums. Median segment closely, rugosely punctured, the 

 punctures running into striae on the apex and on the spiracular 

 arese. Propleuraj shagreened, the meso- and metapleurte closely 

 punctured. Prosternum stoutly keeled in the middle ; its apex and

Enchisiades, gen. nov. 



Mandibles curved, ending in one tooth ; the apex gradually 

 narrowed, rounded. Face flat. Labrum projecting. Clypeus not 

 separated from the face, its apex transverse. Scutellum roundly 

 convex, not much raised, its sides distinctly keeled. Post-scutellum 

 bifoveate at the base ; its sides not keeled. Median segment with a 

 gradually rounded slope, completely areolated, its areola longer than 

 broad, rounded behind, its apex bulging backwards, and with the 

 keel thin. Areolet 5-angled, narrowed above, the nervures almost 

 touching there. Post-petiole broadly dilated, distinctly separated 

 from the petiole. Legs stout; the tarsi long, spinose. Antennae 

 long, slender, slightly but distinctly, dilated towards the apex.

 the pronotum narrowly, the line not extending to the apex, the 

 lower edge of the propleuraj slightly more broadly, the scutellar 

 keels, the sides of the scutellum, post-scutellum, the lateral region 

 of the apical slope of the metanotum, the tubercles, a line on the 

 inner- side of the mesopleura3, commencing above the middle at the 

 base, where it is narrowed along the basal half and more broadly 

 on the lower half, where it is obliquely turned upwards ; two marks 

 under the hind-wings and a small mark al)ove the middle of the 

 hinder coxse, lemon-yellow. Legs rufous ; the four front coxa3 and
