strongly and densely punctate, the punctures a little larger than those of the 

 head and quite distinctly separated ; basal fovese almost obsolete. Elytra 

 nearly four times as long as the prothorax and scarcely wider than the latter, 

 acutely ogival in apical third ; sides subparallel ; disk finely but strongly, 

 quite sparsely punctate, without impressed lines or series, the two sutural 

 however becoming very strong near the apex. Abdomen finely, rather sparsely 

 punctate. Legs slender, the basal joint of the hind tarsi three-fourths as long 

 as the remainder. 



Male. — Unknown. 



Length 7.0 mm. ; width 2.9 mm. 



California (Lake Tahoe). 



This species is distinct in faeies, resembling only oblongula in this 

 respect. It differs however from oblongula in many characters 

 besides those mentioned in the table, as may be inferred from the 

 description. The single specimen appears to be a female, although 

 it is impossible to state this definitely without dissection. From 

 quadristriata it differs in its more elongate form, larger prothorax, 

 which is much more nearly equal in width to the elytra, and in the 

 shorter third joint of the antennae. 



I. oblongula n. sp. — Oblong, rather elongate and subparallel, convex, 

 blackish piceous throughout, the legs and antennae concolorous ; tarsi slightly 

 paler ; suture feebly, narrowly rufescent ; pubescence very short, dense, pale 

 and conspicuous. Head feebly convex, finely, densely punctate, the punctures 

 distinctly separated ; eyes large ; antennae very slender, filiform, rather more 

 than one-half as long as the body. Prothorax fully three-fourths wider than 

 long, the apex subtruncate, scarcely two-thirds as wide as the base, the latter 

 transverse, the lateral sinuations broad and almost obsolete ; basal angles 

 very slightly obtuse, not rounded ; sides broadly arcuate throughout, more 

 strongly so and convergent anteriorly ; disk slightly wider at basal third than 

 at base ; convex, finely, extremely densely punctate, very feebly impressed in 

 the middle near the base, the basal fovese widely, feebly impressed and incon- 

 spicuous. Elytra fully four times as long as the prothorax, and, at the middle, 

 about one-third wider, ogival at apex ; humeri slightly and arcuately oblique 

 externally, not at all exposed at base ; sides very feebly arcuate ; disk with 

 rather distinct but very feebly impressed lines throughout the width, finely, 

 densely punctate, without punctured series. Abdomen minutely, somewhat 

 densely punctate, polished ; propleurae very sparsely so externally. Legs long 

 and slender, normal. 



Male. — Unknown . 



Length 6.8 mm. ; width 2.7 mm. 



New York (Buffalo). 



The single specimen is a female, and has the third joint of the 

 antennae twice as long as the second and three-fourths as long as
