tions on sandy roads, on the railroad tracks, in sandy fields, etc., 

 while 12-guttaki is confined to paths through the cranberry bogs, 

 blackened by vegetation and always damp, and to a few places 

 where the wood paths, running across a stream, make gently sloping 

 banks of blackened sand. The two species do not intermingle at 

 this locality. 



Dr. LeConte mentions " perfectly marked specimens, as well as 

 those of a coppery and greenish color " from Lake Superior, and a 

 specimen of a fine blue color, with very complete marks from Fort 

 Gratiot, Mich.

Dark brown, the elytra feebly, the head and thorax more evidently 

 bronzed, and in part with green and coppery reflections; beneath 

 blue green. Elytral markings consist of humeral and post-humeral 

 dots, middle band not extending along the margin, narrow, obliquely 

 bent and of nearly uniform width throughout, being but slightly 

 dilated at its inner extremity, and apical and ante apical dots. 

 Head striate between the eyes and in front of then) nearly to the 

 labrum, not hairy; labrum obsoletely three toothed; thorax nearly 

 quadrate, granulate, impressions deep, metallic at base, scarcely 

 hairy at sides above ; elytra n(»t suddenly dilated in $ , punctate 

 granulate, serrulate at apex, but only feebly so. Beneath, the 

 hairs are arranged as usual in this group, but they are unusually 

 sparse. 



I am inclined to unite with this species the form occurring in 

 Washington, which is entirely green. It has exactly the same 

 marks as eureka and differs mainly in color and the absence of the 

 serrulation of elytral apex. 



I mention this form so that the description, which is taken from 

 specimens kindly given me by Dr. Van Dyke, may not mislead in 

 respect of color. This is, perhaps, the form of which LeConte had 

 fragments (1. c, p. 41, No. 22).
