CALOSOMA FRIGIDUM Kirby. 



ORIGINAL DESCRIPTION. 



Frigid Calosoma, black underneath with greenish sides; elytra furrowed with the 

 furrows punctured; interstices of the furrows elevated with transverse lines impressed, 

 and a triple series of bilobed obscurely gilded punctiform impressions; margin green- 

 ish; posterior angles of the pro thorax depressed. Length of the body 9 J lines. Taken 

 in Drummond's Island, Canada, by Dr. Bigsby. 



Not unlike C. calidum, but longer in proportion and more depressed. Body black, 

 not glossy above. Head not confluently punctured and wrinkled; mandibles ob- 

 liquely but less densely wrinkled, and frontal impressions longer than in C. calidum; 

 pro thorax scarcely wider than the head, posterior angles bent downward; elytra 

 scarcely at all bronzed, lateral margin obscurely green, with the same number of 

 elevated lines as in C. calidum but in the furrows formed by them is a series of punc- 

 tures, and the transverse lines are less conspicuous; there is a triple series of puncti- 

 form impressions, but they are bilobed, smaller, and the gilding is greenish and less 

 conspicuous; they are also less numerous, there being only seven or eight in the series 

 next the suture, eight or nine in the intermediate one, and three only towards the 

 apex in the external one; at the base there is also a pair on each side; the sides of the 

 body underneath are greenish, punctured and wrinkled. 



EARLY RECORDS OF THE SPECIES. 



The species was first described by Kirby in 1837. Very little 

 further attention was given it until 1848 and 1863, when LeConte 

 included it in his "Descriptive Catalogue and Notes on the Species 

 of Calosoma Inhabiting the United States." This species, like many 

 others of its congeners, often attracts the attention of collectors and 

 is present in most general collections. The senior writer, in 1896, was 

 the first investigator to rear the species successfully through all its 

 stages in confuiement, and a continuation of tlie same work was 

 attempted by himself and the junior writer in 1909 with a fair 

 measure of success. 



DISTRIBUTION. 



This species occurs in Connecticut, Georgia, Illinois, Indiana, Iowa, 

 Maryland, Massachusetts, Michigan, Minnesota, Nebraska, New 

 Hampshire, New York, Pemisylvania, Texas, and Wisconsin. It 

 also occurs in Ontario and Quebec, Canada. Undoubtedly this 

 species has a greater range than that above mentioned but it is more 

 common in the northern part of the United States and in Canada. 



COLLECTIONS AND SHIPMENTS. 



From 1909 to 1912 adults and larv» of this species were collected 

 in the field and brought to the laboratory alive lor biologic study.
