cavernous. Metasternum short; episterna narrow but trace- 

 able throughout. Abdomen with straight sutures; first seg- 

 ment as long -as second and third combined, intercoxal process 

 rather narrow, third and fourth combined slightly longer than 

 second and fifth. Legs moderately long ; posterior coxae almost 

 touching elytra ; femora not stout, grooved, edentate, posterior 

 terminated before apex of abdomen; tibiae rather long and 

 almost straight; tarsi moderately long, third joint wide and 

 deeply bilobed, fourth elongate. Elongate-ovate, strongly 

 convex, striate, squamose, winged. 



Evidently belongs to the Poropterus group, but I know of 

 no closely related genus. 



POROPTERCULUS SUBNITIDUS, n. Sp. 



Piceous-brown and somewhat shining, antennae and tarsi 

 paler. Not densely clothed with depressed and suberect sooty 

 scales, intermingled with a few white ones, and which are 

 more numerous on the under-surface than elsewhere. 



Head convex; indistinctly punctate. Rostrum the length 

 of prothorax, sides very feebly incurved to middle; basal half 

 with coarse, partially-concealed punctures; apical half shining 

 and moderately punctate, an impunctate line along middle. 

 First joint of funicle obconical, the length of second and third 

 combined and much wider, third to seventh transverse. Pro- 

 thorax lightly transverse, base not much wider than apex; 

 with dense, round, deep, clearly cut, non-confluent punctures, 

 suddenly becoming much smaller on apical fourth. Elytra 

 not much wider than, about once and two-thirds the length 

 of, and outline subcontinuous with, that of prothorax ; 

 punctate-striate, punctures indistinct, although rather large; 

 interstices regular, convex, shining, slightly narrower than 

 striae. Abdomen with dense, round, deep, clearly-cut, scarcely- 

 concealed punctures. Femora with dense but rather small 

 punctures, posterior extending to apical segment. Length, 

 2 1 mm. ; rostrum, § mm. ; width, 1 mm.

The elytral punctures are indistinct, except towards the 

 sides, but are not concealed by the clothing, which is almost 

 absent, except posteriorly. 



Pteropoeopterus, n. g. 



Head convex, partially concealed. Eyes ovate, very finely 

 faceted. Rostrum not very long and rather wide, lightly 

 curved, a shallow groove on each side above scrobe. Antennae 

 moderately stout ; scape shorter than funicle, inserted nearer
