148 MEMOIRS ON THE COLEOPTERA 



might possibly be included within its limits, all of its various ele- 

 ments differ in the form and size of the prothorax, giving a notably 

 different habitus. The species of Pseudota are extremely numerous 

 and only a moderate proportion of them were described in my 

 previous paper. The following species have come to light from time 

 to time amongst the unstudied material of my collection: 



Pseudota puricula n. sp. Feebly convex, rather shining, finely, closely, 

 asperately punctate, more densely on the elytra, finely and very remotely 

 on the polished abdomen, except basally, the micro-reticulation there 

 rather large but feeble and irregular; color rufo-piceous, the head and a 

 very large subapical abdominal cloud black, the elytra pale brownish- 

 flavate, feebly infumate at the scutellum and postero-externally, the 

 legs very pale; pubescence very short, not conspicuous; head wider than 

 long, nearly three-fourths as wide as the prothorax, the eyes large, at 

 barely two-thirds their length from the base, the tempora slightly less 

 prominent, at first straight and parallel, then strongly oblique to the 

 base, the carinae very fine, entire; antennae pale piceous, still paler 

 basally, rather short, gradually and distinctly incrassate, the second and 

 third joints moderately long, subequal, the third much the more strongly 

 narrowed basally, fourth slightly wider than long, fifth to ninth equal in 

 length, gradually more transverse, the ninth nearly one-half wider than 

 long, just visibly shorter than the tenth, the last pointed, as long as the 

 two preceding; prothorax moderate, three-fifths wider than long, parallel, 

 with evidently and subevenly rounded sides, the median line feebly, not 

 finely impressed, ending in a small feeble impression at base; elytra at 

 base fully a fifth wider, the suture two-fifths longer, than the prothorax; 

 abdomen narrower than the elytra, parallel, the sixth tergite (cf ) truncate, 

 feebly sinuate in about median half and with a distinct and strongly 

 concave, rounded but not posteriorly prominent auricle at each side. 

 Length 2.4 mm.; width 0.53 mm. New York (Catskill Mts.). 



Distinguishable by its pallid coloration, large eyes and antennal 

 structure. From true Athetae of the nympha class, which have 

 almost similar antennae and coloration, it may be known at once 

 by the smaller and shorter prothorax, impressed along the median 

 line, as well as by the wholly different type of male sexual characters, 

 and, from those of the gnoma type, having almost similar coloration 

 and somewhat similar male sexual characters, it departs very 

 radically in the smaller impressed prothorax, giving a different 

 facies. 



Pseudota fascinans n. sp. More slender and still more depressed, 

 dull in lustre, the punctures fine, strongly asperate and dense throughout, 

 fine and very close-set on all the tergites except the fifth, where they be- 

 come sparse, with the surface shining, the latter gradually more opaque
