have disappeared except the two at the base. The var. B. olivieri, 

 Est., is the form in whicli tliere is no trace of the discal row 

 of spots. 



Abraded specimens are very hke B. herthus, Hbst., but the 

 latter species is sHghtly narrower and the greatest depth of the 

 elytra is at the middle, the posterior declivity being at first much 

 more gradual and becoming more abrupt and slightly sinuate 

 near the apex ; the central furrow on the forehead narrows 

 posteriorly and disappears behind the eyes. In B. oniscus the 

 greatest depth of the elytra is behind the middle and the posterior 

 declivity is eqvially steep throughout ; the central furrow is 

 ■continued evenly on to the vertex.

 Bloxifrus chinensis, Bohemaii, Res. Eug-en. 1859, p. 120. 



Colour black, with fairly dense, uniform, grey scaling, the 

 scales sometimes having a coppery reflexion. 



Head, rostrum, antennce and irrothorax as in B. oniscus, Oliv. 

 Elytra more narrowly ovate, the basal margin subtruncate and 

 broader than the base of the prothorax, but with the external 

 angles scarcely projecting, shoulders obliquely rounded, the 5 

 very rarely with a small humeral tubercle ; upper surface with 

 regular sulci, containing rather smaller and less distinct punc- 

 tures than in B. oniscus, the intervals narrow, evenly raised and 

 with fairly regular rows of shiny black granules; the 5th interval 

 without the posterior tubercles, except very rarely in the $ . 



The apical ventral segment is not impressed in the $ , and the 

 impression in the d is much shallower than in either sex of 

 B. oniscus. 



Length, 5^-8^ mm.; breadth, 2|-4| mm.

Type lost ; type of B. chinensis not traced. 



I agree with Jekel that the Chinese specimens (B. chinensis. Boh.) 

 cannot be distinguished specifically ; they seem to differ from Bur- 

 mese examples only in having the eyebrows slightly jnore elevated.
