THE CANADIAN ENTOMOLOGIST. 163 



marked with a black dorsal vitta ; tip of abdomen greatly swollen, bearing 

 a subconical process m front of the hypopygium. Front and middle 

 tibiae each bearing two bristles on the posterior and one on the outer side 

 below the middle besides those at the tip, hind tibiae each bearing a 

 single bristle on the inner side near the lowest third, three on the front 

 side and two on the outer side, in addition to those at the tip ; under 

 side of each hind femur bearing a row of bristles, those at the base the 

 shortest. Wings hyaline, tinged with gray at the base and less distinctly 

 so in the marginal cell, costa strongly arcuate along the costal cell, costal 

 spine shorter than the small cross vein, the latter beyond the middle of the 

 discal cell, hind cross vein nearly straight and subperpendicular, last 

 sections of the third and fourth veins distinctly diverging ; calypteres 

 whitish, halteres yellow, the extreme base of the peduncle brown. 



? . Front three-fourths as wide as either eye, frontal vitta destitute 

 of a pair of macrochsetae, sides of front yellowish-gray poUinose ; abdomen 

 ovate, pointed at the apex, almost bare, destitute of a black dorsal vitta ; 

 costal spine slightly longer than the small cross vein ; otherwise as in 

 the male. 



Length, 4 to 5.5 mm. Two males and two females, bred by Mr. M. 

 V. Slingerland, from larva; boring in the stems of the cultivated raspberry 

 at Ithaca, N. Y. 



The male, will be easily recognized by the narrow abdomen and the 

 arrangement of the bristles on the legs ; the female, by the absence of 

 the usual pair of macrochaetai on the upper part of the frontal vitta.

Mr. R. H. Meade, of England, sends me the following report upon 

 some of the flies which were sent to him at the same time : " I have 

 examined the flies carefully, and they seem to be an undescribed species 

 of Phorbia. I cannot identify them with any European species that I 

 know, and I think you may describe them as new. You might call them 

 P. rubi or P. ruborum." 



I shall be glad to send a copy of Bulletin 126 to anyone who may 

 be further interested in this raspberry-cane maggot. 



The annual meeting of the Association of Economic Entomologists 

 will be held at Detroit, Mich., on Thursday and Friday, August 12th 

 and 13th,
