308 Report of the Entomologists of the 



low birds and English sparrows feeding upon the moths. TJn- 

 donbtedly many more of our smaller birds feed upon the young 

 caterpillars. 



Predaccous insects. — The predaceous insect enemies herein 

 recorded may be divided into two groups: The coleopterous 

 (beetles) and the hemipterous (bugs). The caterpillars fall an 

 easy prey to these enemies when crawling about upon or near the 

 ground. The following are included in the first group : Calosoma 

 scrutator Fab., and Calosoma calidum Eab., two of our largest 

 species of predaceous ground-beetles, which have frequently been 

 observed attacking caterpillars of various species. Dr. C. V. 

 Riley^^ and Mr. Wm. Saunders^ were probably the first to record 

 them feeding upon the caterpillars of this species. 



According to Eelt,^^ Burgess states that Calosoma wilcoxi LeC. 

 fed readily in confinement upon the caterpillars. Included in the 

 second group are the two predaceous bugs, Podisus placidus Uhler 

 and Podisus seriventris Uhler, which Kirkland^^ has recorded 

 feeding upon the caterpillars. Saunders records^^ a species of 

 Tromhidium feeding upon the eggs. 



Parasitic insects. — The parasitic insect enemies may also be 

 divided into two groups : The dipterous parasites and the hymenop- 

 terous parasites. Of the former group Coquillett^ records the 

 following as parasites of the caterpillars : Ewphoracera claripennis 

 Macq., bred by C. H. Fernald, Amherst, Mass., Frontinia frenchii 

 Will., previously recorded by Harvey^ and Tacliina mella Walk, 

 also previously recorded by Harvey. During the past season 

 the writer has also bred the last named species together with 

 Calliphora erythrocephala Meigen, which Coquillett states is
