mentioned), it seems to differ widely in color and markings, also 

 in having (so far as the example before me is concerned) the 

 elytra not distinctly spined at the apex, and strite 4-6 of the elytra 

 not differing from the rest.

An extremely convex species ; viewed from the side the elytra 

 appear considerably more than halt as high (i.e., from the level of 

 the lateral margin to that of the suture) as long. The blotches 

 on each elytron are as follows : one on the shoulder, two down the 

 suture almost touching it, and one near the lateral margin, but in 

 some examples they are ill-defined, and in some examples some of 

 them are wanting ; the striae and punctures on the elytra are 

 l>lackish Compared with the European B. luridns, Linn., this 

 species is even more convex (especially about the hinder part of 

 the elytra), its head and prothorax are more coarsely punctured, 

 its scutellum is more elongate, and the elytral interstices are a 

 little mo e convex. It differs from B. luridus also in the absence 

 of any raised line on the prothorax, and in the presence on that 

 segment of a system of very distinct (though small) punctm-ps 

 interspersed among the larger ones The puncturation of the 

 underside is close and fine, but rugose. The sternal keel is trace- 

 able only on the mesosternura (which is more declivous than in 

 B. luridas), where, however, it is extremely sharply elevated, its 

 hinder e Ige being truncated and standing out between the inter- 

 mediate legs much above the level of their coxre (a similar
