Scape about as long as funicle. Frotliorax moderately trans- 

 verse, subcorneal, apex about one-third the width of base; 

 with rather dense but irregular punctures ; with a conspicuous 

 median carina, continued to apex but not to base ; with four- 

 small tubercles across middle, but the lateral one very feeble, 

 and two small ones on each side of apex. Elytra subcordate, 

 not twice as long as greatest width, sides strongly dilated from 

 base to basal third, and then narrowed to apex ; with irregular 

 rows of fairly large punctures ; before middle with an irregu- 

 larly transverse (or oblique) row of feeble tubercles, beyond 

 same (except the suture) glabrous and with a few small 

 tubercles. Punctures of under-surface concealed. Femora 

 with dense punctures, the tibiae with distinct ridges. Length, 

 5 mm.

The antennae and tarsi are almost as black as the other 

 parts. At the base of each of the four hind tibiae there is a 

 conspicuous ridge of stout scales that, becoming suddenly ter- 

 minated, causes the tibia itself to appear angularly dentate 

 at its outer base, but the derm is but feebly dilated there. The 

 clothing of the side pieces of the mesosternum cause these to 

 appear like three triangles, of which the median one is darker 

 than the others. The elj'-tra appear to be divided into two 

 parts, the basal and smaller portion partly clothed (near the 

 base part of it is irregularly glabrous) and the apical portion 

 glabrous, but this portion extends irregularly along the sides 

 to the base. The tubercles are small but distinct on the hinder 

 parts, and confined to the third, fifth, and seventh interstices, 

 elsewhere they are less distinct (small granules only), but not 

 confined to those interstices. 



PSEUDOPOROPTERUS. 



Several additional species of this genus having been dis- 

 covered, the original diagnosis needs amendment as follows : — 

 Eyes with facets of variable size. Scape shorter than funicle, 

 its insertion variable. Abdomen with second segment exca- 

 vated or not, its suture with first usually indistinct across 

 middle. Legs short or moderately long, hind femora extend- 

 ing to or just passing apex of elytra. 



PSEUDOPOROPTERUS SULCIFRONS, n. Sp. 



cS . Black ; antennae and tarsi almost black. Densely 

 clothed with scales of varying shades of brown ; with some 

 stout ones scattered about. 



Head with a conspicuous median groove extending almost 

 to base; punctures concealed. Rostrum stout, rather lightly
