gination widely transverse; cavernous. Metasternum short; 

 episterna not traceable. Abdomen with distinct sutures; two 

 basal segments large, first as long as second and third com- 

 bined, apex rather strongly incurved, intercoxal process widely 

 truncate; third and fourth narrow, with deep sutures, their 

 combined length equal to that of fifth and slightly shorter 

 than that of second. Legs rather long; posterior coxae touch- 

 ing elytra; femora linear, feebly grooved, edentate, posterior 

 passing elytra ; tibiae compressed and (except at base) straight, 

 tarsi moderately long, third joint wide and deeply bilobed, 

 fourth elongate. Ovate, strongly convex, feebly squamose, 

 non-tuberculate, apterous. 



Placed amongst the allies of Poropterus, although per- 

 haps not very close to any of them. The small size and shining 

 body of the only known species is suggestive of affinity with 

 Idotasia, but the abdomen and femora are utterly different 

 to those of that genus. It is perhaps a connecting-link between 

 the two groups. 



Gymnoporopterus pictipes, n. sp. 



Black, shining, antennae and tarsi red. Upper-surface 

 glabrous except for a few indistinct scales contained in punc- 

 tures ; sides of rostrum, under-surface and legs, with white, 

 stout, round scales, usually in feeble clusters. 



Head with rather large punctures, base impunctate and 

 slightly iridiscent. Rostrum not much longer than head, 

 about twice as long as wide, sides incurved to middle ; with 

 large, round punctures. Prothorax moderately transverse ; 

 with moderately large but irregularly, and not very thickly, 

 distributed punctures. Elytra not twice the length of and 

 at base no wider than prothorax, widest at basal third, 

 nowhere parallel-sided ; with series of rather small and dis- 

 tant, but round and deep punctures, with series of much 

 smaller punctures intervening ; interstices between the punc- 

 tures not separately convex. Two basal segments of abdomen 

 with large, round, sparse punctures; apical segment rather 

 densely punctate. Femora densely punctate. Length, 3 

 mm.; rostrum, § mm.; width, 1J mm.

The elytra are absolutely without striae. The patches of 

 white scales are very distinct on the legs and sides of rostrum. 



MlCROCRYPTORHYNCHUS ECHINATUS, n. Sp. 



Brownish-red, antennae and tarsi paler. Very densely 

 clothed with muddy-grey scales, which entirely conceal the
