EARLY RECORDS OF THE SPECIES. 



The original description of this species was pubhshed by Kirby in 

 1818/ its habitat bemg given as Chma. In 1831 Dejean^ rede- 

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

 compared it with auropunctatum Payk. in general marldngs and says 

 it should be placed near senegalense Dej. The literature concernmg 

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

 the two references above cited. 



OCCURRENCE AND IMPORTATIONS. 



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

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

 second shipment m 1910 were received specimens of Carahus proce- 

 rulus Chaud., C. tuherculatus Fisch., and Damaster Uaptoides Kollar. 

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

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

 large sliipments were made from the Imperial Agricultural Experi- 

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

 packed smgly in wooden boxes with damp sphagnum moss. About 

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

 ments were made with the steamship company whereby the boxes 

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

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

 m many of the smaU boxes was still damp on arrival, and the beetles 

 on the whole were m very fine condition, 83 per cent being aUve 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, whicli 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 feedmg records were kept of four pairs of beetles received 

 from Japan, July 22, 1910.
