264 THE CANADIAN ENTOMOLOGIST. 



Cavicorjiis is taken in some abundance by Mr. Dury near Cincinnati, 

 and globosus is also common there ; the latter is apparently the most 

 abundant and one of the most widely-diffused species of the genus. 

 Frontalis^ Lee, is the largest and finest species known to me, and is also 

 widely diffused, though less common; all my examples are males, and 

 were taken in Pennsylvania, Missouri and Wisconsin. 



Pyaioplectus^ Csy. 

 The species of Eupledus^ as regarded by Raffray, were divided by 

 the writer (i\.nn. N. Y. Acad., 1893, p. 454) into three groups, then held 

 to be subgeneric. Subsequently (1. c, 1897, p. 552) cogent reasons were 

 given for regarding the first of these groups as of full generic value, and I 

 am even more convinced of the correctness of this course now than then. 

 It may be added that the third group, there composed of pertenuis alone, 

 is also a distinct genus to be described subsequently. 



Pycnopledns Floridce^ n. sp. — Moderately stout, bright testaceous 

 throughout, polished, impunctate, moderately and somewhat sparsely 

 pubescent ; head wider than long, the eyes well developed, convex, at 

 rather less than their own length from the base, the tempora moderately 

 converging and rounded ; two pubescent fovece separated by fully half the 

 total width, the ambient sulcus very coarse and deep, triangular in course, 

 with the apex narrowly truncate behind the thick and medially depressed 

 frontal margin ; antennae a little longer than the head and prothorax, the 

 last three joints very gradually wider ; occiput feebly and narrowly 

 impressed at the middle ; prothorax wider than long-, as wide as the head, 

 the three subbasal and single discal fovene well developed ; elytra about 

 as long as the head and prothorax and much wider, rather longer 

 than wide^ the basal impression obsolete at basal fourth, the intermediate 

 basal fovea small but distinct ; abdomen not quite as wide as the elytra, 

 and evidently longer, the first two dorsals impressed and bicarinate 

 medially at base. Length, 1.3 mm.; width, 0.3 mm. Florida. 



Resembles Hudsonicus somewhat, but much more completely impunc- 

 tate, and having more elongate antennae and relatively longer elytra. 



Pycnopledns longipennis^ n. sp. — Form somewhat as in Floridce^ 

 slender, similarly impunctate, polished and moderately convex, dark 

 testaceous, finely, not conspicuously pubescent, the hairs decumbent; head 

 but little wider than long, nearly as in FloridcE ; prothorax much less 

 transverse and decidedly narrower than the head, but little wider than
