8 THE CANADIAN ENTOMOLOGIST. 



abdomen in length ; sides parallel, not widened at tip ; of a deep 

 smoky-brown colour, almost opaque. Nerves very scrong and simple, 

 the radial and two ulnar nerves run straight and undivided to the 

 transverse nerve, which crosses the elytra a little beyond the tip of 

 the clavus, forming three large cells' on the base of the corium ; the 

 second ulnar is forked at the transverse nerve, the first ulnar is twice 

 forked beyond the transverse, and between this and the radial is a 

 short nerve from the transverse to the costa ; these forming seven 

 apical cells, of which the medial is small and triangular, and the next 

 inner the largest and rectangular ; the claval nerves unite beyond 

 the middle, the resulting nerve joining the claval suture just before 

 its apex. 

 Peltonotus Jiistrionicus Stal. One example. Occurs also at Buffalo. 



Cercopidce. 



Lepyronia quadrangiilaris Say. Rare. 



ApJirophora qiiadyiuotata Say. Very abundant on the lowlands, but 



mostly immature; the imagines were just beginning to appear. 

 Aphropho7-a parallella Say. Common on pines. 

 Ap/irophora saratogciisis Fitch. Rather more abundant than the pre- 



ceeding, with which it occurred and which it greatly resembles ; it is, 



however, readily distinguished by the more obtuse head, clearer 



markings, and concolorous punctures. 

 Clastoptcra obiiisa Say. Very common on the blueberry. 

 Clasioptera protms Fitch. With the last. 



n 



Bytlioscopidcc. 



Idiocerus pallidus Fitch. Abundant on willows, birches, etc. 

 Idiocerus siititralis Fitch. On low poplar bushes near the river ; even 



more abundant than the preceeding. 

 Idioccrtis lachrymalis Fitch. Numbers of this, our largest species, occurred 



on birch and other trees. 

 Idiocerus altcrnatus Fitch. Scarce. It is with slight misgivings that I 



place this insect here, although I believe future study will justify the 



reference. 

 A gain a novellns Say. As abundant at Muskoka as in New York ; on 



grass and weeds.
