AMERICAN COLEOPTERA. 129 



Mr. Harris collected assiduously about Stamford, N. Y., during the 

 past summer, and in a large series of specimens there was practically 

 no variation from the peculiar color of the specimens first noticed 

 in Litchfield County, Conn. Further investigation of mountain 

 forms collected by Mr. Beutenmiiller in North Carolina, showed 

 that the expected character was again developed. 



Var. violacea Fab., Syst. El. i, p. 232; Schaupp, I.e., p. 89, pi. ii, fig. 33 (not 

 fig. 34, which is intended to represent the eight spotted form oi sexguttata). 

 Length 12-14 mra.=.48.-.56 inch. 



Habitat. — Onaga, Kansas ; Mr. F. F. Crevecoeur. 



DiflTers from sexguttata by its rich violaceous color and by its 

 tendency to be immaculate, though it occurs two, four and six 

 spotted. Mr. Crevecoeur takes the true violacea along dry creek 

 beds in company with the immaculate form of .sexguttata. In many 

 collections immaculate specimens of sexguttata, either with or with- 

 out the bluish reflection that is not uncommon, stand under the 

 name violacea, but I believe, incorrectly. The true violacea is one 

 of the most beautiful of our species. 



My friend, Mr. George Coverdale, has sent me a series of sexgut 

 tata from Vowell's Mill, La., in which every degree of maculation 

 is represented in specimens taken at one time and place. C. varians 

 Ljungh, identified by Dr. Walther Horn, of Berlin, as a form of our 

 sexguttata in which the markings are reduced to a marginal dot, is 

 represented in the series sent me by Mr. Coverdale and, if correctly 

 placed as an American insect, is to be regarded as a synonym.

 Length 12-14.5 mm.=.48 .58 inch. 



Habitat— Wis. ; Pa. ; Md. ; N. Y. ; N. C. ; in shady paths on hills. 



Differs from .sexguttata in being usually larger; in having a com 

 plete middle band and a humeral lunule, rarely complete, usi'allv 

 represented by humeral and posthumeral dots; in the color which is 

 usually darker; in the pilosity beneath, the metathorax being well 

 covered and the density of the hairs on the mesothorax, coxre and 

 femora being much greater than in C sexguttata; and in being con- 

 fined to comparatively few stations. 



Recent captures are by Mr. Nathan Reist and Mr. Ezra J. Nolt 

 on Chickies Rock, which is a high, rocky and wooded mound on
