Var. ro^uensis Harris, 1901, Canadian Entomologist, xxxiii, p. 226. 

 Length 12-15 mni=.48-60 inch. 



Habitat— Go\d Hill, Oregon ; Kalispell, Mont. 



Dark green, almost black in some specimens, thorax often shaded 

 with cupreous; beneath green, pleurae cupreous. Humeral and 

 apical lunulas usually interrupted. In the Montana specimens the 

 remnant of the humeral lunule closely approaches the middle band 

 as in var. obliquata. 



Var. sierra n. var. 



Length 12-13 mm.=.48-.52 inch. 



Habitat. — Sierra Co., Cal. 



Brilliant green above, and beneath with bluish reflections. Ely- 

 tral markings very narrow and inconspicuous, consisting of humeral 

 dot, very small, confined to the declivity and sometimes lacking, 

 sometimes a short oblique line to represent the extremity of the 

 humeral lunule, sometimes no trace of the lunule remains; middle 

 band normal, usually very slender, sometimes reduced to a marginal 

 dot; apical lunule usually interrupted. 



Five specimens loaned by Mr. Charles Fuchs, of San Francisco, 

 indicate that a race has developed in the Sierra Nevada, in which 

 the tendency is towards a disappearance of the elytral markings. I 

 cannot discover any diflerences beyond those named above, except 

 that beneath the hairs are very sparse. 



Repanda group. 



Tliorax less convex, even evidently flattened in some specimens, not margined, 

 subquadrate or quadrate; palpi % pale at base; elytra less convex, 

 serrulate at tip, except in depressula, granulate-punctate, markings 

 usually narrow, never entirely connected at margin, often reduced to 

 dots; last veutral segment % asymetrically emarginate. 

 Elytra 9 suddenly dilated in front of the middle, elytra 'J, not dilated ; humeral 

 lunule upturned at lower extremity. 

 Elytra serrulate at tip. 



Front hairy, or granulate punctate before the eyes. 



Markings complete, not connected at margin repanda. 



Markings partially connected, heavy var. uiiijiiiicta. 



Elytra 9 gradually dilated ; apex serrulate. 

 Front hairy or granulate-punctate. 



Markings broken, form broader and flatter IS-gutlata. 



Front not or scarcely hairy, striate in front of the eyes as well as between 

 them. 



Brown with complete uniform middle band eureka. 



Markings usually broader, broken more or less into dots.
