Head rather small : with dense and coarse punctures. 

 Rostrum rather long and thin, lightly curved; basal two-fifths 

 with coarse punctures and feeble ridges, elsewhere shining and 

 with small punctures. Scape inserted one-third from apex of 

 rostrum; second joint of funicle longer than first. Profhorax 

 and elytra with sculpture as described in preceding species. 

 Under-siirface with dense and rather coarse punctures. Basal 

 segment of ahdomen gently convex. Femora strongly dentate; 

 tibiae strongly compressed, each with a thin outer flange, ex- 

 tending almost its entire length ; with rows of punctures, 

 separated by ridges. Length, 1\ mm.

Readily distinguished from all previously described species 

 by the wide and strongly compressed tibise. In general appear- 

 ance it is like the preceding species, but the front tibise are 

 without a median tooth. On the elytra the ochreous-red scales 

 are more noticeable about the summit of the posterior declivity 

 than elsewhere on the upper-surface ; before and after same 

 there are a few sooty scales, but they are indistinct, owing to 

 their close resemblance to the derm. On the flank of each 

 elytron there is a small conspicuous spot as on the preceding. 

 and on several other, species. The type is probably a female. 



Omydaus sculptilis, n. sp. 



Black; antennae and tarsi obscurely diluted with red. 

 Irregularly clothed with scales, varying from almost white to 

 rusty-brown. 



Head with some small, clearly-defined punctures; a deep 

 narrow impression behind each eye. Rostrum moderately 

 long, lightly curved, sides gently dilated towards base ; about 

 base opaque and with not very large punctures, elsewhere 

 shining and with small ones. Scape inserted about two-fifths 

 from apex of rostrum, very little shorter than funicle; two 

 basal joints of the latter subequal in length. Protliorax 

 distinctly transverse, sides strongly rounded, and near apex 

 deeply and narrowly impressed; with some large irregular 

 punctures on sides and some smaller ones about apex ; across 

 median two-thirds with two deep and very conspicuous curved 

 impressions, the median one interrupted in middle, the other 

 not interrupted. Elytra distinctly wider than prothorax, 

 scarcely twice as wide as long, base trisinuate, sides sub- 

 parallel to beyond the middle ; with rows of large, distant 

 punctures, becoming smaller towards sides and almost absent 

 posteriorly. Under-surface with small and sparse punctures. 

 Metasternum with a curved impression across middle. 

 Abdomen with a strongly-curved impression towards base of
