 broader than long, arcuately narrowing from about the middle, feebly constricted in front, bisinuate at

 rounded humeri, obtuse at the apex, the disc with one or two faint transverse depressions towards 

 the sides; very finely punctate-striate, the seventh and eighth striae obsolete for some distance below 

 the shoulder, the interstices broad, flat, alutaceous, each with one or two rows of minute punctures

2. Sphenophorus mundus, sp. n. 



Subfusiform, rather broad, black, opaque and somewhat flattened above, faintly pruinose. Head coarsely, 

 sparsely, irregularly punctate in front, foveate and transversely grooved between the eyes ; rostrum 

 barely as long as the prothorax, abruptly bowed from the short, broad, irregularly punctate basal portion, 

 the apical portion subcylindrical, rather slender, almost smooth. Prothorax about as long as broad, 

 obliquely narrowing from a little beyond the middle, feebly constricted in front ; punctured along the 

 sides, base, and apex, the disc arcuately depressed posteriorly and almost impunctate. Scutellum 

 triangular, flattened. Elytra moderately long, considerably wider than the prothorax ; finely striate, 

 the striae with closely placed rather coarse oval punctures, which become rounded towards the sides, the 

 interstices flat and almost smooth. Pygidium coarsely, closely punctate. Beneath sparsely punctured, 

 the punctures becoming coarse towards the sides. Femora sparsely ciliate beneath, the tibiae fringed with 

 extremely short hairs, the latter almost straight on their outer edge. Tarsi with the third joint broad, 

 spongy-pubescent beneath.
