1 One female was dead on receipt. 



Mr. H. P. Loding, Mobile, Ala., under date of April 8, 1910, wrote 

 the senior author the following concerning this species : 



Our most common Calosoma is C. sayi Dej., which occurs here in some numbers 

 dining the latter part of July. This insect is found frequently around electric lights 

 in the city and I have also found it preying upon caterpillars of various species on 

 low shrubbery and herbage. 



This gives an idea of the occurrence and habits of the species in 

 that section. 



FOOD CONSUMED BY ADULTS. 



Only a few feeding records were attempted and these are incom- 

 plete because many of the beetles died. A male received from Wash- 

 ington, D. C, May 26, and a female from Oklahoma, June 19, 1910, 

 were fed in a jar from June 20 until July 21 and 23, when both died. 

 One hundred and twenty- three full-grown caterpillars of Malacosoma 

 americana and Porthetria dispar were consumed by the pair during 

 the month they lived. 



One female received from Washington, D. C, May 28, 1912, was 

 fed in a jar until it sought hibernation August 30. Seventy- two 

 caterpillars of Malacosoma americanaj M. disstria, Porthetria dispar, 

 and Estigmene acraea, ranging from fourth to sixth stage, were con- 

 sumed. No eggs were deposited by this female and no male was 

 available for a mate. 



REARING AND HIBERNATION RECORDS, 1910-1912. 



All the beetles received in 1910 were paired in jars, but neither 

 copulation nor deposition of eggs followed, and all died at the end of 

 that season. Only one female was received in 1912. x\s no males 

 of this species were available, three males of C. calidum were placed 

 in the jar with the female between June 8 and 13, but neither copula- 

 tion nor reproduction ensued. The female was put into a hibernation 

 cage August 30 and died late in the fall.
