the 1st subgroup, and the elytra much wider than the prothorax 

 (so that viewed from the side they descend much below the level 

 of that segment) connecting it with the 5th subgroup; but its 

 prothorax entirely devoid of fovere and with well defined hind 

 angles prevents its confusion with either of those aggregates.

Another somewhat isolated species owing to the exceptional 

 sculpture of its prothorax (which bears on the lateral portion, on 

 either side, two subparallel elongate furrows with the space 

 between them somewhat elevated — this sculpture, however, feebly 

 marked in some examples) as well as the strong (less strong in 

 some examples) convexity near its apex of the interstice between 

 the 2nd and 3rd elytral series. The insect is entirely testaceous or 

 testaceous-brown, except that in some examples some of the inter- 

 stices on the elytra are interruptedly whitish. It is very nitid, 

 strongly convex and somewhat elongate-oval in form, the outline of 

 the elytra (viewed from the side) strongly sinuous. The elytra are 

 -scarcely striate, their seriate punctures somewhat strong and not 

 very closely placed in the series, the interstices finely and sparsely 

 punctured. The antenna3 are robust and somewhat short, with 

 the external joints considerably compressed and not very much 

 longer than wide, the basal joint somewhat elongate and reaching 

 well on to the eye. In the male the basal joint of the four 

 anterior tarsi is somewhat strongly dilated, with its sides con- 

 siderably rounded. I may say that the whitish colour of some 

 of the elytral interstices in some dried examples of this insect 

 are suggestive of the probability that when alive its elytra are 

 striped with metallic colours, but I cannot speak positively on 

 the point, as I have not seen living specimens. Its habitat is 

 N.S. AVales. I have an example named by Dr. Chapuis.
