basal punctures more advanced towards the middle, and tlie- 

 antenna inserted a trifle closer to the apex of rostrum. 



Rh^bocnemocis, n.g. 



liexLcl of moderate size and evenly convex. Eyes large, 

 coarsely faceted. Rostrum long, thin, and curved. Antennae 

 thin: scape inserted rather close to apex of rostrum, and con- 

 siderably passing same; two basal joints of funicle moderately 

 long ; club elongate-elliptic, sutures oblique. Prothorax trans- 

 verse, sides rounded, base almost truncate. Scufellum distinct.. 

 Elytra much wider than prothorax, sides parallel to beyond the 

 middle. Pectoral canal narrow, deep, terminated between 

 middle coxae. Mesosternal receptacle U-shaped, walls thin; 

 slightly cavernous. Metasternum slightly shorter than the fol- 

 lowing segment. Abdomen large, suture between two basal 

 segments indistinct in middle, third and fourth comparatively 

 large, their combined length distinctly more than that of second 

 or fifth. Legs long ; femora stout, strongly dentate, hind pair 

 passing apex of elytra; tibiae compressed, falcate; tarsi thin, 

 first and fourth joints elongate. Squamose, fasciculate, 

 winged. 



Some of the characters, especially of the under-surface, 

 appear to denote an approach to Pezichus, but the legs are very 

 different and the elytra are without the small fascicles of 

 whitish scales (10) just beyond the middle that are almost in- 

 variably present in the allies of Protofalus. It appears to be 

 allied to Oniclustus, and may be placed after Cratomerocis, 

 from, which it differs in its unidentate hind femora, abdominal, 

 sutures, and base of head. 



RniEBOCNEMOCIS POSTERUS, n. sp. 



d" . Black; rostrum, antennas, and tarsi more or less red- 

 dish. Rather densely clothed with brownish scales, variegated 

 in places with paler and darker ones; with fairly numerous, 

 suberect scales interspersed. 



Head with punctures concealed. Eyes separated less than 

 width at base of rostrum. Rostrum slightly longer than pro- 

 thorax, somewhat dilated towards but notched on each side of 

 base ; basal third with rather coarse, concealed punctures, else- 

 where with sparse and small ones. Scape inserted about one-- 

 fifth from apex of rostrum. Prothorax moderately transverse, 

 sides strongly rounded, apex more than half the width of 

 middle ; punctures dense, but normally concealed. Elytra sub- 

 cordate, base distinctly trisinuate ; with rows of rather large, 



(10) There are several spots of whitish scales on the elytra, but 

 not elevated into fascicles.
