THE CANADIAN ENTOMOLOGIST. 409 



Lepyronia qiiadraJigularia. Say. — Two from Island Lake, and one 

 very dark example from Fox Island, in Red Cedar Lake. 



Aphrophora paral/eia, Say. — One example from Red Cedar Lake, 

 August 9th. 



Aphrophora Saratogensis, Fitch. — One pair taken with the preceding. 



Clastoptera obttcsa^ Say. — Very abundant at all stations. Generally 

 taken on willows. These individuals average much darker than those 

 from New York State, 



Clastoptera proteus^ Fitch. — This species seems also to have been 

 abundant, especially about Red Cedar Lake. Nearly all the specimens 

 brought home by Mr. Palmer were of the black form. These have only 

 the lower surface of the face and the legs yellow, and the apex of the elytra, 

 and sometimes the base of the costal area, are brownish ; a few have two 

 transverse bands on the front of the pronotum. the clavus, except a broad 

 longitudinal median viita, and an oblique vitta across the middle of the 

 cor.ium, yellow. 



Gypona flaviliiieata, Fitch. — Two females were taken at Red Cedar 

 Lake, August 9th. 



Gypona Quebecensts, Prov. — Two males and two females and larvae 

 were taken at Island Lake and Red Cedar Lake. This species is now 

 generally placed as a synonym of the preceding, but I still think it should 

 be kept distinct, although on further study the name may have to be sunk 

 as a synonym of one of Burmeister's unidentified species. It may be 

 distinguished iioxvi flaviliiieata by its smaller size, deeper green colour, 

 longer vertex, more approximate ocelli, more numerous transverse 

 nervures on the elytra, and different form of the last ventral segment of 

 the female. This seems to be a more northern form, which I have taken 

 about Buffalo from Hemlock bushes. 



Diedrocephala coccinea, Forster. — Numerous specimens of this insect 

 were brought home by Mr. Palmer. Apparently they were common and 

 generally distributed. 



DrcBcidacephala NovceboraceiiAs, Fitch. — Several were taken at Red 

 Cedar Lake, and one at the Island Lake lumber camp. These specimens 

 are a little smaller, with the black markings of the vertex more distinct 

 than in those captured about Buffalo. 



Drceciilacephala Ma?iiiobia?ui, Ball. — One male taken at Swamp 

 Creek, August 14th. This individual agrees in all respects with Prof 

 Ball's figure and description, except that the male plates are distinctly
