150 CHARLES W. LENG. 



Habitat— Col, Nev., N. Mex., Mont., Cal., Or., Wash., Vane; 

 probably from the Rocky Mts. westwards. 



Bronze brown, varying to dull cupreous in Colorado and to nie 

 tallic green in California, the color always more evident on head 

 and thorax, beneath bluish green and in part cupreous ; elytral 

 markings consist of humeral and post humeral dots, middle band, 

 and apical and anteapical dots; the middle band enters perpendicu- 

 larly, is bent obliquely and is quite unequal in width, its extremity 

 being heavy and often disconnected. The elytral markings in 

 oregona are often conspicuously broad. Head bald, finely striate 

 between and in front of the eyes ; labrum obsoletely three-toothed ; 

 thorax slightly narrower behind, flat, impressions deep, usually green 

 at base, not hairy at the sides ; elytra subparallel S , evidently 

 broader 9 , but gradually so, not suddenly dilated as in repanda, 

 granulate punctate, serrulate at tip. Beneath, the flanks of thorax, 

 coxae, pleurse and legs are thinly clothed with white hair, the sides 

 of abdomen very thinly clothed also. The greener specimens ap 

 proach in appearance the peculiar form found at Phoenix, Arizona, 

 which is called in many collections (juttifera Lee, but the descrip- 

 tion of LeConte and the types in his collection do not support the 

 practice, and guttifera must be regarded as a synonym.

Length 12-13.5 mm.— .48-. 54 inch. 



Habitat. — Phoenix, Arizona. 



Similar to the preceding, except that the head and thorax are 

 brilliant metallic green, while the elytra are dark violet, margins 

 shining violet; beneath violet, metallic, shining. The elytral mark- 

 ings are similar to those of oregona and very heavy. 



This is a geographical race of oregona, which has for a long time 

 been separated in collections under the name guttifera, which was 

 applied by Dr. LeConte to an insect corresponding with oregona.

Green, head and prothorax in part with a coppery reflection ; 

 beneath green ; the elytral markings consist of post-humeral dot, 

 often lacking, middle band, apical and anteapical dots ; the middle 

 band is short, does not attain the margin, obliquely bent, narrow
