>6 THE CANADIAN ENTOMOLOGIST. 



specimens proved that they were not coiispersa at all, but agreed exactly 

 with specimens of C. ahdom'malis, which I took during the summer of 

 1897 at Banff, in the Rocky Mountains, and in the Province of Manitoba, 

 except that the tegmina are a little longer, especially in one of the 9 s, 

 in which they are nearly twice the length of the pronotum, while in the 

 Western specimens they are only very slightly longer than the pronotum. In 

 the other % from the Severn they are only about one-fourth as long again 

 as the pronotum. 



C. abdomijialis is easily distinguished from C. coiispersa not only by 

 the greater size and the paler sides of the pronotum in the $ , but also by 

 the more arcuate lateral carina, especially in the $ . ^^ery few conspersa 

 were seen during my canoe trip. 



My specimens are dated Aug. 15 and 18, 1898. This is the first 

 time it has been recorded from Canada, and the first time east of Dakota. 



Encoptoloplius sordidus, Burm. — This species was quite common at 

 Toronto last fall, aad during a bicycle trip along the lakeshore I found it 

 gradually increasing in numbers as I rode to Hamilton and Niagara Falls. 



Scirtetica ffiartnorata, Harris. — I found this beautiful locust exceed- 

 ingly numerous last summer all along the Severn River, in many places 

 being even more abundant than Cii-cotettix verriiculatiis. It flies about 

 the bare gneiss and granite rocks and on the dry, scanty soil which partly 

 covers them. 



THE ODOUR OF COCCID.E. 



Prof, Webster's interesting note on p. 4 leads me to offer a few 

 remarks. The species of the sub-genus Toumeyella of Lecanium have 

 quite a strong musky odour ; but ordinarily I have been unable to detect 

 any marked odour in species of Coccidae. I suppose, however, that all 

 possess some odour, and that its purpose is to attract the males to the 

 females. This seems the more probable when we remember that in many 

 species the male puparia are not on the same part of the plant as the 

 females. Here at Mesilla Park, also, I have lately seen a male of 

 Margarodes hiemaiis, Ckll. ined., run over the ground until it detected a 

 spot where a female was buried, and then dig down to the female. It 

 must certainly have detected its mate by the sense of smell.
