1911] Champlain — Carabidce in Connecticut 35 



SOME CARABIDiE TAKEN IN CONNECTICUT. 



By Alfred B. Champlain. 

 Agricultural Experiment Station, New Haven, Conn. 



Among the Carabidse taken in Connecticut during the past 

 year, 1^10, a few, mostly from the vicinity of New Haven and 

 Lyme, seem worth recording. 



A series of arc lights near the Experiment Station yielded a 

 number of interesting species to which the "at arc" records refer. 



Omophron tessellatum Say. New Haven, 22 June, one specimen at arcs. 



Cychrus lecontei Dej. appeared to be quite plentiful; at Lyme, Oct. 9, 

 I captured three pairs and a number of single specimens. 



Cychrus elevatus Fabr. Lyme, 25 Sept., 9 Oct.; this species has been taken 

 in almost every section of the state, and the preceding species is undoubtedly 

 as well distributed. 



Cychrus viduus Dej. is represented in the Station collection by one speci- 

 men taken July 7, 1905, at Torrington, Ct., by Dr. W. E. Britton. 



Calosoma externum Say, New Haven, 19 May, 1903, one specimen, 

 collected by B. H. Walden. 



Calosoma scrutator Fabr., Conspicuous by its absence. But one specimen 

 taken at arc lights. 



f 1 G. willcoxi Lee. Plentiful at arc lights and under stones in May and June. 

 Observed upon trees feeding upon canker worms. 



It G. frigidum Fabr. New Haven, May and June. Also collected by the 

 men employed in turning bands in gypsy moth work at Wallingford. 



C. callidum Fabr. Several at arc lights. One specimen observed feeding 

 upon Serica sp. directly under arc. 



Carabus nemoralis Mull., Hartford, Ct., 1 Sept., 1909, R. W. Curtis; 

 New Haven, Ct., 2 April, 1906, Miss E. B. Whittlesey; Oct. 3, Nov. 3, 1910, 

 D. J. Caffrey. 



Carabus sylvosus Say. Lyme, May, July, October; this is the narrow form. 



Trechus chalybeus Mann. New Haven, 19 Nov.; two specimens taken 

 in swamp, under fallen leaves. 



Myas cyanescens Dej. Lyme. A few specimens were taken in July and 

 Sept. from under fallen branches and logs, and one specimen was dug from the 

 stem of a toadstool. Mr. C. A. Frost of South Framingham, Mass., writes 

 me that he has taken this species under fungi while digging for Geotrupes. 

 The specimens all measured about 17 mm. in length, and in size nearly 

 approach my Pennsylvania specimens of M. coracinus Say. 



Pterostichus adoxus Say, very common in and under dead logs. P.
