THE GENUS CALOSOMA. 

 EARLY RECORDS OF THE SPECIES. 



1 1 5 



The original description of this species was published by Kirby in 

 1818, 1 its habitat being given as China. In 1831 Dejean 2 rede- 

 scribed it as coming from the same country. The latter author- 

 compared it with auropunctatum Payk. in general markings and says 

 it should be placed near senegdlense Dej. The literature concerning 

 this species is rather limited. The writers were able to secure only 

 the two references above cited. 



OCCURRENCE AND IMPORTATIONS. 



Three hundred and fifty-three adults were collected and shipped to 

 the gipsy moth parasite laboratory in two years. Along with the 

 second shipment in 1910 were received specimens of Carabus 'proce- 

 rulus Chaud., C. tuberculatus Fisch., and Damaster blaptoides Kollar. 

 A specimen received January 5, 1910, was collected and mailed by 

 Rev. H. Loomis, 53 Main Street, Yokohama, Japan, while the two 

 large shipments were made from the Imperial Agricultural Experi- 

 ment Station, Tokyo, by Prof. S. I. Kuwana. The beetles were 

 packed singly in wooden boxes with damp sphagnum moss. About 

 40 of these small boxes were inclosed in a large wooden box. Arrange- 

 ments were made with the steamship company whereby the boxes 

 were kept hi cold storage as far as Vancouver, British Columbia, and 

 were then shipped by express, in larger boxes containing ice. The moss 

 in many of the small boxes was still damp on arrival, and the beetles 

 on the whole were in very fine condition, 83 per cent being alive on 

 receipt. They were en route 18 days. 



HABITS OF ADULTS. 



The adults of this species are able to fly to some extent. They 

 also climb trees, which was demonstrated in 1911. Experiments 

 conducted indicate that the adults are able to attack either ground 

 or tree inhabiting caterpillars. 



FOOD CONSUMED BY ADULTS. 



Daily feeding records were kept of four pairs of beetles received 

 from Japan, July 22, 1910.
