lobed at tip, the last dorsal very short, broadly rounded and with 

 a feeble apical sinuation. 



R. turgidicornis. — Strongly convex and ventricose, shining, subim- 

 punctate, the pronotum minutely, feebly and remotely punctulate ; body black, 

 the elytra pale rufous ; legs piceous-black, paler distally ; antennae black, the 

 first four joints paler ; pubescence short, strongly and closely recurved and 

 moderately dense. Head much narrovrer than the prothorax and about equally 

 long, the vertexal fovese moderate in size and about equidistant from base and 

 apex ; eyes prominent, moderately large, at much less than their own length 

 from the base. Antennas stout and very irregular, distinctly longer than the 

 head and prothorax, the club normal and very gradually formed ; basal joint 

 not unusually large; second but little narrower, nearly globular, the next two 

 still narrower, small and transverse ; fifth large, dilated, much wider than 

 long, gradually pointed within ; sixth shorter but very nearly as wide ; seventh 

 as wide and long as the fifth, less pointed within ; eighth abruptly very much 

 smaller, transverse, pointed internally, the next two obtrapezoidal ; under 

 surface of the fifth joint convex and scarcely modified, the sixth with a narrow 

 vertical ligula projecting from the basal margin, the seventh not excavated 

 but with the surface gradually and acutely elevated toward the middle of the 

 basal margin. Prothorax ^5 wider than long, widest near apical third, the 

 sides there rather strongly but not prominently rounded, thence moderately 

 convergent and feebly arcuate to the base ; apex wide, % the maximum width 

 and % as wide as the base ; fovese normal but only moderately developed. 

 Elytra short, at least }4 wider than long, more than twice as wide as the pro- 

 thorax, the humeri widely exposed at base and rounded, with distinct plica ; 

 sides moderately divergent and broadly arcuate ; striae and fovese normal. 

 Abdomen a little narrower and much shorter than the elytra, the first segment 

 less than ^ as long and rather more than three times as wide as long ; carinse 

 rather feeble, nearly straight, strongly divergent, not extending to basal third 

 and separated at base by a' little more than }'^ the total width. Legs moderate 

 in length, slender, the femora unusually slender, the posterior not notably 

 modified ; hind tibise strongly arcuate throughout, feebly thickened toward 

 tip. Length 1.25 mm. ; width 0.68 mm. 



California (Sta. Monica, Los Angeles Co.). Mr. H. C. Fall. 



Allied in the structure of the front and in other features to the 

 preceding species, but differing profoundly in the sexual modifica- 

 tions of the median joints of the antennal funicle and of the hind 

 femora. The male modification of the ventral apex is virtually 

 the same in both. 



Sagax Lee, was also taken by Mr. Fall at Sta. Monica ; a draw- 

 ing of the male antenna is given for comparison. The under 

 surface of th enlarge fourth joint is flattened and coarsely asperate ; 

 the club is rather roughly though not densely sculptured and 

 with unusually long and bristling pubescence.
