For the past 15 years the stems of currant bushes in widely sepa- 

 rated localities have been injured more or less by an insect boring in the 

 tender tips, causing them to wilt or lop over and eventually die. It was 

 not till 1891, however, that the author of the mischief was reared and 

 identified as Janus fla%<iventris Fitch, which has since been referred by 

 Mr A. D. MacGilIivray to Janus integer Norton {see Bull. 126 Cornell 

 agricultural experiment station. 1897. p. 41). Up to the present year 

 there has been no reason for su->pecting that there was more than one 

 insect injuring the currant stems in this particular manner. 



New currant pest. The currant twigs of Mr Thomas Tupper of 

 Corning, N. Y., have suffered more or less from the currant stem girdler, 

 Janus integer, for the jiast 10 years, although the insect was not identified 

 till 189 1. In 1895 Mr Tupper informed me of his finding several 

 black saw-flies associated with the currant stem borer, which he thought 

 might be the male of that species. Specimens of this black insect were 

 finally obtained, both by captures in the field and by rearing from 

 infested twigs. They were submitted to the division of entomology, 

 U. S. department of agriculture, where they were identified by Mr Mar- 

 latt as Tenthredo rufopectus Norton.
