Phijtophaga Malayana. 105 



body in length, basal joints slender, five upper joints broadly 

 dilated, the seventh to the ninth gradually increasing in width. 

 Thorax rather broader than long ; sides rounded and converging 

 from base to apex, posterior angles armed with an obtuse tooth, 

 the anterior tliickened ; upper surface transversely convex, sides 

 very strongly and obliquely deflexed in front, causing the anterior 

 half of the thorax to appear subconic ; disk impressed with irregu- 

 lar punctures. Elytra broadly oblong, convex, transversely ex- 

 cavated below the basilar space, the depression extending from 

 just within the suture to the outer border, humeral callus slightly 

 prominent ; surface finely but not very closely punctured, the 

 punctures arranged indistinctly in longitudinal rows ; intermediate 

 tibiffi strongly flexuose. 



I only possess two specimens of this insect, both $ and do not 

 know the $ ; the robust form, and broadly dilated antennae, will 

 separate it from any of its congeners with a similar form of face.

Head very coarsely and deeply punctured, front swollen, im- 

 pressed with the usual longitudinal groove, which becomes deeper 

 near its end, anterior margin separated from the encarpae and 

 epistome by a deep sutural groove, obtuse, the lateral angles 

 rounded, the middle produced into an angular lobe ; epistome 

 not longer than broad, subcampanulate^ surface rugose-punctate ; 

 encarpae cultriform, their upper portion thickened ; antennae 

 scarcely more than half the length of the body, fusco-aeneous, five 

 upper joints narrowly dilated, purplish-black, apex of last joint 

 obtuse. Thorax scarcely broader than long, sides nearly straight 

 and parallel at the base, rounded and converging from behind 

 the middle to ihe apex, hinder angles armed with a sliort acute 

 tooth ; above convex, subconic in front, the sides anteriorly being
