touching the well-defined clypeal suture. Eyes of moderate 

 size, prominent, and widely separated. Prothorax about twice 

 as wide as the median length, front angles unarmed ; with 

 coarse punctures, not very dense on middle, but crowded on 

 sides. Elytra parallel-sided to beyond the middle, very little 

 wider than prothorax at its widest ; with rows of large punc- 

 tures, rapidly becoming smaller, and almost disappearing 

 before apex. Flanks of 2)rosfernu77i rather strongly striated 

 about base, and moderately about middle, but not elsewhere. 

 Femora minutely dentate : claws bifid. Length, 3| mm.

The lateral punctures of the prothorax are coarser than on 

 any other species in the Museum. On the type the elytral 

 punctures appear to be very large, even to the apex, but this 

 is due to watery rings : at the base they are really large, but 

 posteriorly (as impressions) they almost disappear. There is 

 a small black spot on each side of prothorax, on each 

 elytron there is a pcstmedian one on the third interstice, one 

 on each shoulder, and some irregular ones on the sides behind 

 same, on each femur there is a small spot, the sterna (except 

 part of prosternum) and base of abdomen are blackish.

Black and flavous. 



Head more convex than usual ; with fairly dense, well- 

 defined punctures, becoming slightly denser and larger on 

 clypeus; medio-frontal impression feeble or absent, clypeal 

 suture feeble. Eyes comparatively small, prominent, and 

 widely separated. Protlwrax not much wider than long, sides 

 subangulate at basal third, front angles unarmed ; with dense 

 and large punctures, smaller in middle than elsewhere. EJyfra 

 briefly suboblong, much wider than prothorax ; with rows of 

 large punctures almost, or quite, disappearing posteriorly. 

 Flanks of prostermim with dense and large punctures. Femora 

 minutely dentate; notches of hind tibiae rather feeble; claws 

 each with a large basal appendix. Length, 2-2^ mm.

The conspicuous punctures on the prosternum, although 

 not unique in the genus, together with the small size, should 

 render the species easy of recognition. There are two speci- 

 mens in the Museum, differing strikingly in the colours of 

 elytra, but quite evidently belonging to but one species. They 

 have the head and prothorax black, with a brassy or brassy- 

 green gloss, under-surface black, antennae flavous at base, but 

 infuscated outwardly, and leg's entirely flavous. On one the'
