wide as the apex ; each with four even series of sliort stiff setse. Abdomen 

 as wide as the elytra and about three-fourths as long, the border of the first 

 segment one-fourth of the disoal width, the latter one-third greater than its 

 median length. Legs moderate, the femora thick and subclavate, the tibiae 

 strongly thickened toward apex ; second posterior tarsal joint compressed, 

 much thicker than the third and equal to it in length. Length l.G mm. ; 

 width 0.7 mm. 



New York. 



The single specimen is of undetermined sex. The fourth palpal 

 joint is rather thick, about as long as the prothorax and has the 

 clavate part thickly covered with long erect pale ashy hairs. 



P. bellax n. sp. — Rather slender and depressed, polished, suhimpunc- 

 tate, nearly glabrous and dark rufo-testaceous throughout. Head rather 

 longer than the prothorax and fully as wide, the upper surface sparsely 

 setose, polished, not at all reticulate anteriorly, sparsely punctulate behind, 

 esspecially at the posterior margins of the pale spots, these punctures bearing 

 longer stiff setae recumbent over and beyond the spots ; frontal channel and 

 occipital groove well developed ; antennse nearly two-thirds as long as the body, 

 somewhat scabro-reticulate throughout, the cylindrical basal joint nearly as 

 long as the next three, second almost as thick as the first, ninth longer and 

 narrower than the tenth, eleventh stout, obliquely oval, as long as the pre- 

 ceding two joints combined, less scabrous but with sparse asperate punctures. 

 Prothorax suhcylindrical, widest at the middle ; sides broadly arcuate ; base 

 and apex truncate and equal; surface very convex, impunctate. Elytra as 

 long as wide, three-fourths longer than the prothorax and two and one-half 

 times as wide ; humeri very oblique and obtuse; base one-third as wide as 

 the apex ; each with four even series of erect distant setse. Abdomen as wide 

 as the elytra and three fourths as long, of the usual structure ; border wide. 

 Letjs moderate, more slender throughout than in fuatifer, the second posterior 

 tarsal joint but slightly thicker and decidedly longer than the third. Length 

 1.4 mm. ; width 0.55 mm. 



Massachusetts ; Michigan. 



This species is very closely allied to the European heisei, but 

 differs in its rather smaller size, and especially, narrower form, in 

 the somewhat stouter and more abruptly formed palpal club, and 

 in the longer antennal club, the three last joints of the antennie 

 being together much shorter than the seven preceding in heisei, 

 while in bellax the club is fully as long as the funicle. I obtained 

 two specimens at Taunton in damp moss; the three specimens be- 

 fore me are equal in size and almost similar in structure, the sexual 

 characters being apparently very feeble.
