impression between the eyes ; clypeus emarginate, feebly bidentate ; occiput 

 smooth, impunctate. Thorax slightly longer than wide, widest a little behind 

 the middle ; sides in front nearly straight and slightly convergent, posteriorly 

 rather strongly convergent and slightly arcuate. Elytra at base very slightly 

 wider than the thorax, widest at the middle, twice as long as wide, two and 

 one half times as long as the thorax ; sides evenly and feebly arcuate from base 

 to the semicircularly rounded apex; base not margined; stria strong, entire, 

 rather finely and distantly punctured on basal half, indistinct and evanescent 

 posteriorly; the third stria bipunctate, anterior puncture a little before the 

 middle, posterior at apical one third. Length, 4-4.25 mm.; width, 1-1.25 

 mm. 2 (^. 



In LeConte's table of the genus, this species would be placed with 

 spliccricoUis, from which it is distinguished by its smaller size, slightly 

 elongate thorax with the sides in front nearly parallel. D. edcntnlus 

 Putz. also placed with sphocricoUis, is a large species, "mm. in length, 

 with impunctate third elytral interval and the striae obliterated 

 posteriorly. 



Hydnobius laticeps new species. 



Form oblong oval, strongly convex. Color uniform rufo-testaceous. Head 

 broad, finely and sparsely punctate, labrum bilobed. Thorax twice as wide as 

 long, scarcely narrower at apex than at base, widest at middle, sides evenly 

 but not strongly arcuate ; distinctly and rather sparsely punctate. Elytra oval, 

 rather oblong; sides gradually narrowed and arcuate from base to apex; 

 sutural stria obsolete at base, gradually more strongly impressed to the apex 

 where it approaches the margin ; surface with rows of rather coarse and closely 

 placed punctures, very feebly impressed ; intervals with more or less irregu- 

 larly placed punctures of equal size. Body beneath not distinctly punctured. 

 Length, 2 mm.; width, 1 mm. i ^. 



Male. — Anterior and middle tarsi not distinctly dilated, posterior femora 

 with a rather broad tooth, obliquely truncate at apex; posterior tibiae, straight, 

 rather strongly dilated at apex. 



Female. — Unknown. 



This species may be distinguished from substriatiis and latidcns 

 by its large head and thorax not distinctly narrowed in front and 

 by the shorter tooth of the posterior femora and the more strongly 

 dilated tibiae. 



Actobius fulvicomis new species. 



Form slender, elongate, parallel, subdepressed. Color black, elytra piceous 

 brown, indefinitely darker on the suture and basal third ; antcnnx. mouth pans
