Mr. Bowditch, and on the banks of Cazenovia Creek, eight miles 

 from Buffalo, N. Y., by Mr. Ottomar Reinecke. In the last locality 

 the season is May and June and again in August. The date on 

 my N. H. specimens is also June.

Thorax convex, not margined, narrower behind; palpi % bale at base; elytra 

 convex, markings narrow, not connected at margin, humeral lunule 

 much longer than usual, obliquely prolonged ; front granulate, hairy ; 

 labrum three toothed ; elytra granulate jninctate, not serrulate at apex.

Varies exceedingly and exhibits a tendency to develop into a 

 large number of local races. Tho.se which are more widely separa- 

 ted are as follows : 



Black, humeral lunule entire vulgaris. 



Bright bronze, thorax cupreous, lunule entire var. Iioricoiieiisis. 



Dull bronze, markings verv broad var. obliquata. 



Bright green, humeral lunule broken var. vibex. 



Brilliant blue-green, humeral lunule lacking. var. sierra. 



Dull green, humeral lunule broken var. rogiiensis. 



In addition to these there are other departures from the typical 

 form. The humeral lunule is prolonged at a more or less obtuse 

 angle, or is broken, or (in specimens from North Carolina) it nearly 

 disappears; the middle band enters transversely in some specimens 

 and quite obliquely in others ; its extremity closely approaches the 

 apical lunule in some, while it is widely separated in others; the 

 apical lunule is rarely interrupted, but even this occurs in some 

 specimens of roguensis and sierra. Some specimens are very hairy, 

 while in others the hairs are far from conspicuous. The extraordi- 

 nary variation in size is shown above. 



C vulgaris (typical).— Black above, dark green beneath ; elytral markings, 

 moderately wide, consist of humeral lunule obliquely prolonged, middle band
