THE PAINTED HICKORY BORER 181 



of golden yellow lunules along the abdomen, caused by yellow pile; but 

 the anal segment of pictus showed one median, dorsal, narrow and oblong 

 spot of gold, while the corresponding spot in robiniae was obtusely tri- 

 angular. 



Another somewhat extensive discussion of this insect was set forth by 

 Webb (1911). A list of the trees attacked was given and also, the range 

 of the insect. Brief notes were furnished concerning the life history of 

 the species and recommendations were made for preventing the injury 

 which it causes. 



The synonymy of this species is as follows:

DISTRIBUTION 



The distribution of the hickory borer is in all pfobability coextensive 

 with that of its food plants, the hickories. Kirkpatrick (1856) recorded 

 it from northern Ohio as breeding in hickory. Walsh (1864) stated that 

 about six years previously he had split this insect from hickory at Rock 

 Island, Illinois, while Professor Sheldon, of Davenport, Iowa, informed 

 him that he had found it in hickory at that place for many years back. 

 Walsh (1866) reported the insect rare in Illinois, having taken only three 

 specimens during a seven-years collection. He stated, however, that it 

 was common near Philadelphia, Pennsylvania, in walnut and hickory. 

 Larvae of this species were sent to Walsh from Kansas in 1867, for identi- 

 fication. Rogers (1880) reported that it was one of the common species 

 in Ontario. Smith (1890) reported the insect as being generally dis 

 tributed, tho rare in New Jersey. In 1892, C. C. Black sent several 

 specimens from Connecticut to Riley, stating that they had emerged from 

 hickory firewood. Bruner (1893) mentioned it as being very destructive
