Ariz. (Wickham) ; Montana (Blanchard). The western localities 

 cited by Scliaupp are possibly doubtful, as the next species is the 

 one usually found in Cal. and Wash. 



Brown, green, blue or black, beneath green or black ; elytral 

 markings consist of white line on the subniargin, separated from the 

 margin by a narrow black stripe, dilated towards the apex, with 

 uarrow humeral and middle branch both descending obliquely, the 

 latter sinuate; or they consist of oblique humule luuule, oblique 

 middle band connected with a submarginal line and apical lunule ; 

 and rarely the markings are reduced to an oblique abbreviated 

 humeral lunule, triangular submarginal spot and apical lunule; but 

 always the narrow separation of the submarginal line from the mar- 

 gin is preserved. (It might be possible, with more material than I 

 have, to separate these forms as geographical races, but at present I 

 cannot do so.) Head striate to the labrum, not hairy; thorax with 

 the sides slightly rounded, a little narrower behind, with a fringe of 

 hair on either side; elytra subparallel, punctulate, sericeous, not 

 serrulate at apex ; beneath, the palpi, coxae, pleurae, flanks of thorax 

 and sides of abdomen are sparsely hairy. Prof. Schaupp followed 

 Dr. LeConte in describing the elytra as "stnmgly punctate," which 

 is incorrect.

 Length 9-12 mm.=.36-.48 inch. 



Habitat— ^acrameuto, Cal. (LeConte) ; Or., Wash. (Blanchard) ; 

 Cal., Or., Nev. (Schaupp); Idaho, Or., Wash. (Wickham). Prof. 

 Wickham took this species abundantly early in June, along the 

 banks of a small creek near The Dalles, Oregon, and again at 

 Wenatchee, Wash., July 5th. 



Diflers from the preceding in -the type of its markings and in 

 geographical distribution. The middle band is always at a consid- 

 erable di.stance from the margin. In one form the humeral lunule 

 is long and oblique and connects with the middle band, which is 

 also long and oblique, but does not touch the normal apical lunule. 

 In the other form the markings are more slender and are all di.«con- 

 nected, long oblique humeral lunule, long oblique middle band not 

 reaching the margin and normal apical lunule. Otherwise this 

 species is identical with cinctipennis.
