Head evidently wider than the thorax, eyes moderately prominent. 

 Thorax quite strongly transverse, sides straight and parallel, rather 

 strongly margined. Length (head deflexed) 23^ mm. to tips of elytra. 



Abdominal sexual characters. Male: sixth ventral very deeply, 

 broadly emarginate, the emargination truncate at bottom, seventh 

 narrow, very elongate, polished, yellow, very sparsely pubescent, 

 gradually narrowed for two-thirds its length, then widened and deeply 

 forked; as viewed in profile, horizontal in rather more than basal half, 

 then rather abruptly sinuately ascending; last dorsal not produced. 



California. Tulare Co., June 25, 2d', 1 9. Type d^. 



Malthodes visceratus sp. nov. 



Fuscous or fuscotestaceous, thorax yellow with side margins more or 

 less infuscate. Antennas entirely fuscous, as long as the body in the

 longer, intermediate joints fully four times as long as wide. Head (cf ) 

 not much wider than the thorax, narrower than the thorax in the female. 

 Thorax strongly transverse in both sexes, sides nearly straight and 

 parallel, strongly margined, the margin thickened at front angles. 

 Length 2 to 2J^ mm. 



Abdominal sexual characters. Male: sixth ventral broadly, deeply 

 emarginate, the emargination truncate at bottom; seventh elongate, 

 deeply, broadly divided at apex, the forks slender, strongly up-curved 

 basally in profile, then bent suddenly in horizontal direction; sixth (?) 

 dorsal acutely projecting downward at sides to enclose the last ventral.

EXPLANATION OF PLATE IIL 



All figures show the outline of the sixth and seventh ventral segments of the 

 male, and beneath them in each case, except Fig. 1, the seventh ventral as viewed 

 in profile. In cortiplicatus, Fig. 11, is shown also one of the downward projecting 

 dorsal appendages, between which the seventh ventral lies.
