ClCINDELID/E AND CARABID^ 



Much smaller than femiginea, with which this is probably most 

 closely allied and with feebler, less definite elytral costse, relatively 

 smaller prothorax and somewhat shorter elytra; the antennse are 

 of nearly the same type; the depressed lines of the elytra are more 

 sparsely, less strongly and more bilinearly punctate, the punctures 

 being less broadly confused throughout than in ferrnginea. The 

 head is much more distinctly narrower than the prothorax in 

 ferruginea than it is in languida. 



Lebia Latr. 



The species furcata of LeConte, belonging to the group Aphelo- 

 genia Chd., is composite in most collections, comprising a number of 

 distinct forms having mutually a very close superficial resemblance. 

 The body is pale yellow throughout above and beneath, the elytra 

 with three black vittse, not attaining the apex, the one op the suture 

 bifurcating basally. G. H. Horn discovered one of these allied 

 species, having entirely black legs, and named it depicta. Those in 

 my collection may be known as follows : 



Head much narrower than the prothorax in both sexes 2 



Head subequal in width to the prothorax, relatively much larger than 

 in the preceding group 5 



2 Legs black throughout, the femora sometimes pale at the extreme base, 

 the tibiae always black; antennae and palpi black, the former with the 

 basal joint pale; elytral striae wholly impunctate. Length 6.0-6.3 

 mm.; width 2.75 mm. New Mexico (Las Vegas) and Colorado 

 (Boulder Co.). Montana Horn depicta Horn 



Legs not entirely black, the femora pale basally, the tibiae pale externally 

 except in debiliceps, the tarsi always black 3 



3 Sutural black vitta, at the middle of the length, much narrower than 

 the adjoining pale vitta. Body larger, distinctly broader in outline; 

 head, prothorax and antennae nearly as in furcata; elytra decidedly 

 broader, more oblong, less inflated posteriorly, the sutural vitta 

 bifurcating from just before the middle, the striae impunctate; legs 

 as in furcata, only moderately slender. Length 7.3 mm.; width 3.2- 

 3.3 mm. California (Mendocino Co.) sonomae n. sp. 



Sutural black vitta never decidedly narrower than the pale vitta 4 



4 The sutural vitta at the middle about equal in width to the adjoining 

 pale vitta. Head well developed, with very prominent eyes; pro- 

 thorax fully twice as wide as long; elytra about a third longer than 

 wide, the striae not distinctly punctate externally, the sutural black 

 vitta bifurcating from just before the middle. Length 6.8-7.2 mm.; 

 width 2.9 mm. Wisconsin (Bayfield) to Louisiana (Alexandria). 

 Lake Superior and Platte River LeConte furcata Lee. 



The sutural vitta very much broader, the portion on each elytron equal
