subapical one is larger than the submedian one ; hind tibiae 

 also bidentate externally, each with the subapical tooth larger 

 and stouter than the other, which is at about the basal third ; 

 front tibiae bidentate at apex. Length, 6-6J mm.

Allied to latirostris, but smaller and less cylindrical, and 

 eyes, antennae, legs, and prothoracic punctures somewhat 

 different. On the prothorax the dark scales occupy the major 

 portion of the surface, leaving the paler ones in feeble lines 

 and patches. On the elytra they occupy most of the basal 

 fifth, but elsewhere they form but small spots (rather numerous 

 across the middle, however). 



PSEPHOLASOMA, U. g. 



Head fairly large. Eyes rather large, round, coarsely 

 faceted. Rostrum rather short and wide, dilated to apex; 

 scrobes rather deep and wide, posteriorly suddenly opened, 

 owing to the lower portion of the rostrum being suddenly trun- 

 cated. Antennas short and stout ; scape distinctly shorter than 

 funicle : funicle with two basal joints subtriangular, second 

 longer than first, all the others strongly transverse ; club ovate. 

 P?'othora.x transverse, apex subtubular. Scvtellum small. 

 Elytra subparallel-sided. Pectoral canal wide and rather 

 shallow, walls strongly rounded, but in front rather acutely 

 margined. Mesosternal plate transverse, sides slightly pro- 

 duced in front. Metasternum rather long ; episterna distinct. 

 Ahdomen with two basal segments large. Legs moderately 

 long ; femora stout ; tibiae with subapical tooth and apical 

 spur. 



In my table of the genera allied to Fsepholax (^6) could 

 hardly be placed, as the walls of the basal half of the pectoral 

 canal are widely rounded and the apical half acutely mar- 

 gined ; in several species of P scpliolax there is an approach to 

 this structure, but the species described below has the middle 

 tibiae without a median tooth. But from all the genera there 

 noted it may be distinguished by the sides and under-surface 

 of rostrum. Seen from below the basal half of the rostrum 

 appears to be only about half the width of the apical half, 

 owing to the sudden cutting away of its sides to make room for 

 the antennae : from the sides the rostrum appears to be notched 

 at its base. With the antennae at rest, however, these appear- 

 ances are obscured. The genus is perhaps nearest to Pseudo- 

 tlierehus, but in that genus the rostrum is longer and other- 

 wise different. In Zeneudes, Oreda, and in the male of Pseudo- 

 therehus cylindricus the scrobes are open at their hinder end,
