coarser near the base. Eli/tra distinctly shorter than wide, broadly, evenly 

 inflated and rounded at the sides toward base, distinctly wider than the pro- 

 tliorax but scarcely one-half longer ; oblique basal strise very short but deeply 

 eroded ; suture acutely elevated ; indexed flanks not striate ; punctures coarse, 

 circular, deep, perforate, separated by rather less than their own widths. 

 Pygidia somewhat coarsely and closely punctate throughout. Under surface 

 very coarsely, rather closely but not confluently punctate; hypomera coarsely, 

 deeply concave ; posterior lobe of the prosternum vt^ry small, rather feeble, 

 tuberculiform, bearing a few rather long setiform hairs. Legs short; anterior 

 tibiae somewhat abruptly dilated, externally rounded and with seven or eight 

 short erect acuminate spicules in apical two-fifths. Length 1.2-1.3 mm. ; 

 width 0.7-0.75 mm. 



California (Lake Tahoe). 



The dense cribrate sculpture and minute posterior lobe of the 

 prosternum will enable one to separate this species at once from 

 fraternuK, which occurs abundantly in the same region, and, from 

 cribrafus, it may be readily known by its smaller size, shorter 

 elytra — more rounded at the sides and more rapidly narrowed be- 

 hind, — more narrowly margined and more unevenly sculptured pro- 

 notum, pale coloration and several other characters. 



PARNIDiE. 



The Parnida; are closely related to the Ileterooeridae, and those 

 genera allied to Dryops display, in addition, an unmistakable affinity 

 with the Elateridae. Their life habits are so obscure that probably 

 only a somewhat small proportion of the species are known at 

 present, and the number of genera is very large in proportion to 

 the species. 



PSEPnEXUS Hald. 

 The species known to me may be arranged as follows: — 



Impression of the head not longitudinally divided ; elytra uniform in colora- 

 tion. 

 Sides of the prothorax strongly convergent, the apex not more than one-half 

 as wide as the base ; antennae longer {trentonensis Zimm.). 



lecontei Lee. 



Sides of the prothorax feebly convergent, the apex much wider, two-thirds 



to three-fourths as wide as the base. 



Sides of the prothorax broadly rounded and subparallel toward base, 



more convergent and nearly straight anteriorly falli n. sp.
