TWENTIETH ANNUAL MEETING. 



109 



joined margins of the wing covers, are all a bright, lively brown. The 

 scutellum and two spots on each wing cover are white. These spots divide 

 each wing cover into three nearly equal j^arts. The anterior spots are 

 small and occasionally double; the others are larger and crescent-shaxjed. 

 Beneath, the insect is bright brown, and it is deeply punctured throughout, 

 especially over the entire upper surface. 



The same remedy that avails in ridding our currant stalks of the ajgerian 

 caterpillar will also banish this cerambycid grub. It only remains to urge 

 that the vines be pruned early and so thoroughly that all the miners shall 

 suffer cremation. 



THE NEW CUEEANT BOEEE. 



The past season a new cerambycid borer, Hyperplatys maculatus Hald., 

 whose place and style of work differs in no essential respect from the other 



two currant borers, was discovered depre- 

 dating upon this important plant. The 

 beetle was first discovered as a currant 

 borer by a post-graduate student of my 

 laboratory, Mr. G. C. Davis. The follow- 

 ing is in substance taken from Mr. 

 Davis' thesis on borers: Like the other 

 borers, so this species works in the upper 

 portion of the stems. Riley speaks of 

 this as a borer in apple twigs and Schwarz 

 found it in twigs of poplar. The beetles, 

 which come forth in June, are one fourth 

 of an inch in length and one tenth of an 

 inch in width. The aritennse are long 

 and slender, about twice as long as the 

 body. The color is gray, dotted with 

 black. The head is smoky brown, with a 

 longitudinal groove over the vertix and 

 front. The eyes are transverse, rather 

 finely granulated, and nearly divided by 

 the antennae. The first joint of the antennse is large, the second short and 

 small, and both nearly black. The remaining joints are light brown, 

 except at the tips, which are black. The thorax is not margined, and is 

 broadest near its hind extremity, where a spine extends out and back on 

 each side. Four black' dots form a curved transverse row, convex 

 anteriorly across the thorax. Each wing cover has from twenty to thirty- 

 five black dots in four indistinct rows. These spots vary much in form 

 and size. The hinder margins of the elytra are concave, with sharp angles. 

 The elytra shows distinct lateral carinse. The under parts are all dark 

 gray, except the base of each femur, which is light brown. 



The same remedy that banishes the segerian and extirpates the Ameri- 

 can currant borer or grub, will also exterminate this new pest. 



Thus we see that in this wise, judicious pruning of early May, we kill 

 three birds with one stone, save our currants, and make possible jelly, 

 jam, tarts, and jelly-cake.
