slightly wider than prothorax, shoulders rounded, apex entire, 

 suture nowhere raised; each with ten rows of rather large regular 

 punctures, scarcely larger and more regular at sides than near 

 suture, but becoming smaller and more elongate towards apex, 

 each carrying a scale; interstices not raised, tuberculate or granu- 

 late, wider than punctures and feebly punctate; on each side of 

 and close to suture at base a small but very distinct shining 

 tubercle suddenly elevated, and (in some specimens) rather 

 irregular at apex. Under surface with rather dense, regular, 

 moderately large and circular punctures, entirely absent on inter- 

 coxal process, and scarcer on metasternum and basal segment of 

 abdomen than elsewhere. Abdomen uniformly feebly convex, all 

 tlie sutures distinct, basal segment about once and one-half the 

 length of 2nd ; intermediates conjointly shorter than 2nd, and 

 longer than apical. Legs moderate; posterior femora in ^ just 

 passing intermediates, in ^ not quite passing ; tibite straight, 

 compressed, thicker in ^ than 9; 3rd tarsal joint rather widely 

 bilobed, reddish, claw-joint setose, no longer than 1st. Length 7, 

 rostrum 2 (vix); width 3J mm.

A very distinct species belonging to the varicosus-%\:o\y^, from 

 any of which it may be distinguished by its very regular punctures 

 and the two basal tubercles of elytra. I have one specimen 

 resembling P. (uifiquiis in miniature. In some specimens the 

 punctures appear to be larger than in others, and as each puncture 

 carries a large scale, those on the abdomen, base of rostrum and 

 beneath fascicles cannot be seen unless the scales be removed.
