male antennae and legs, and in its strongly marked abdominal 

 sexual characters. 



R. taplirocera. — Eather strongly ventricose, convex, shining, black, 

 the elytra rufous; legs red-brown, the antennee dark red-brown; head toward 

 base, pronotum except along the middle and toward base, elytra and abdomen 

 toward tip, finely, feebly and sparsely punctulate; pubescence fine, short, 

 moderately dense and closely recurved. Head only very slightly narrower 

 than the prothorax, somewhat wider than long, the vertexal fovese widely 

 separated, deep and equidistant from base and apex; eyes moderately promin- 

 ent, situated at about }4 their length from the base. Antennx slightly longer 

 than the head and prothorax, the club gradually formed but large and stout; 

 portion beyond the second joint arcuate in repose; second joint large, excavated 

 beneath; third obtriangular, wider than long; fourth still wider, twice as wide 

 as Ions; fifth moderately dilated, suboval, slightly transverse; sixth equally 

 wdde but shorter, parallel, % wider than long; seventh and eighth equal in 

 width and very slightly narrower, the former slightly wider than long and 

 longer than the sixth, the latter shorter, more pointed within, % wider than 

 long; ninth a little wider, evenly obtrapezoidal, % wider than long; tenth 

 evenly obtrapezoidal and about as long as wide; eleventh normal, obliquely 

 pointed, stout, about as long as the four preceding; the sixth and seventh joints 

 are irregular beneath, the latter with a deep irregular pit. Prothorax % wider 

 than long, widest but not very prominently rounded before the middle; sur- 

 face very convex, serially punctured along the basal margin for a short dis- 

 tance, the median fovea rather small but deep. Elytra well developed, slightly 

 shorter than wide, the suture % longer than the humeral width; sides rather 

 feebly divergent, broadly and distinctly arcuate throughout ; humeral swelling 

 very moderate; strise and fovese normal. Abdomen nearly as wide as the elytra 

 and ^ as long, the caringe of the first segment fine, strongly divergent, straight, 

 extending not quite to basal third and separated at base by }^ the entire 

 width. Legs rather slender, the hind tibiae broadly arcuate throughout, 

 gradually clavate with circular cross-section toward tip. Length 1.2 mm.; 

 width 0.6 mm.

This species was briefly referred to by me (Bull. Cal. Acad. 

 Sci., II, p. 195) as deforvfiata Lee, and the antenna was figured 

 on the accompanying plate under the same name ; it is a smaller 

 species than deformata, the latter diflfering besides in having the 

 second antennal joint larger and unexcavated beneath, the sixth 

 joint oblique and subtriangular, sixth and seventh slightly nar- 

 rower, equal in size and transverse and the eighth still smaller 

 but equally transverse, the elytra, also, broader at base with more 

 developed humeri. The male of this species has the last ventral 

 moderately large, flattened but not impressed, and with a rounded
