and almost iinjmnetate, between the ridge and clypens with sparse and minute 

 pnnctnres, the sides with rather dense ones. Clypeus semicirenlar, sides feebly 

 and evenly elevated ; with dense punctures, transversely confluent or vermiculate, 

 except at l)ase, where they are sparsely and separately impressed; suture 

 trisinuate and carinated throughout, median siniis slightly arched forwards, and 

 about three-fifths of the total. Eyes moderately narrow, facets distinct. Pro- 

 thorax large, sides strongly rounded and wider than elytra, front angles strongly 

 produced and subacute, almost vertical and impunctate in front ; the declivity 

 crowned by four tubercles, the outer of these subconical and separated from the 

 median ones by a shallow excavation, the median ones connected by a narrow 

 ridge; median line wide and shallow, basal gutter shallower than lateral, and 

 margin less elevated ; Avith moderately large and dense, l)ut not very deep punc- 

 tures; sublateral foveae fairly deep. Elytra with narrow, geminate striae, con- 

 taining transverse distant punctures; interstices shagreened and opaque, Avith 

 small shallow punctures. Metasternum Avith dense, asperate punctures on sides, 

 becoming larger and sparser about coxae, and small in middle. Apical segment 

 of abdomen strongly narroAved to middle ; pygidium shagreened and Avith fairly 

 dense punctures. Length, 12-13 mm.

 connecting ridge ; from base to clj'peus Avith sparse and minute punctures, but 

 becoming fairly large and dense on sides. Clypeus almost semicircular, sides 

 slightly elevated, apex rather higher than sides; Avith fairly dense punctures at 

 sides, but smaller and sparser in middle ; suture trisinuate, and carinated through- 

 out, median sinus slightly arched forAvards, and about' three-fifths of the total. 

 Eyes large, facets inconspicuous. Prothorax Avide, sides strongly rounded, front 

 angles strongly produced, lateral margins and gutters conspicuous, front ones 

 feeble, basal absent; apical half obliquely sloping, and Avith sparse and minute 

 punctures, elscAvhere Avith slightly larger ones; sublateral foveae rather shallow.
