new Species of Histerida3. 253 



join in front ; the thorax has a fine lateral marginal stria, 

 with a fovea at the base on either side well within the angle, 

 and behind the anterior angles there is a rather wide area with 

 rather large shallow punctures, but on the scutellar and discal 

 regions the punctures are sparse and almost wanting; the 

 elytra, striee, outer humeral somewhat well-marked, basal 

 and dimidiate, inner humeral almost complete, also the first 

 dorsal stria, 2-3 less marked and shortened apically ; the 

 propygidium is very clearly, evenly, not coarsely, but rather 

 densely punctured ; the pygidium is less densely and less 

 distinctly punctured ; the prosternum, the keel is truncate 

 anteriorly at the suture, surface flat and less punctured at the 

 base than on the fore part, base lightly impressed on either 

 side of the mesosternal projection, and it is margined laterally 

 with a fine widely sinuous stria, the anterior lobe is on a lower 

 plane than the keel and widens out anteriorly and is closely 

 covered with large shallow punctures ; the mesosternum is 

 bisinuous anteriorly ; the metasternum is bistriate on either 

 side ; the anterior tibia? are dilated and rounded off on the 

 outer edge, the median and posterior tibiae are more dilated 

 and angular in the middle of the outer edge. 



This is the only species of the genus described which is 

 oval in outline.

L. 4 mill. 



Oblong-oval, convex, black and shining, with the thorax 

 obscurely coppery and the elytra rich violet-blue. The fore- 

 head and clypeus are somewhat coarsely punctured, stria ante- 

 riorly is bisinuous and somewhat indistinct, but it is carinate 

 over the eyes ; tlie thorax, marginal stria complete, with a 

 broad lateral margin of coarse punctures which are continued 

 along the basal edge and less strongly behind the neck, disk 

 impunctate; the elytra, strige, external humeral complete, 

 inner shortened apically and scarcely reaching the base, 1 

 dorsal touches the base and posteriorly it is a little shorter 

 than the inner humeral, 2 is a little shorter than the first, 

 3 is as long as the inner humeral, 1-2 are markedly incurved
