THE CANADIAN ENTOMOLOGIST. 23 



CASSIDA VIRIDIS, LINNRUS. 



In the October number of the Canadian Entomologist, I told 

 of the appearance at Levis of a tortoise-beetle new to this Province. 



A question as to the identity of this insect having been raised, 

 I asked Professor E. A. Popenoe, of Kansas State Agricultural College 

 (to whom 1 was sending specimens), for his opinion upon it. I als<) sent 

 specimens to the Coleopterist of the British Museum, with a like request. 

 Both gentlemen very kindly answered me. 



Mr. Popenoe wrote : " In Redtenbacher's Fauna Austriaca, the 

 only general European work on the species within my reach, there is 

 a very good analytical table and fairly full descriptions of the species 

 within the limits of the work, and I find your specimens to agree wiih his 

 description of Cassida equestris, Fab., of which he places C. viridis, L., 

 as a synonym. I am satisfied that your determination is correct. Redt. 

 says the margin of the abdomen is yellow, and it is so in one ot your 

 specimens, though not distinctly so in the other." 



Mr. Chas. O. Waterhouse replied : " I have carefully examined the 

 Cassida you sent me, and I am sure it is our common thistle species, 

 Cassida viridis, L." 



I am glad to find that my reading and my early recollections of the 

 English insect did not mislead me. 



In Illustrations of the Linnean Genera of hisects, by W. Wood, 

 Vol. I., there is a coloured representation of C. viridis, and in the 

 Rev. J. G. Wood's Insects at Home, Fig. xxiii., the insect is shown in 

 its different stages. 



C. viridis, like the fly, Pegomyia bicolor, and the moth, Metzneria 

 lappella, was probably brought out in supplies of fodder for cattle sent to 

 this country. — Thomas W. Fyle.s, Levis, P. Que.
