34 THE CANADIAN ENTOMOLOGIST. 



lobes, three between second and third, next a large pair, then 

 another larger pair, and then a group of five to nine. These 

 characters are quite variable. 



Comparing the above with Comstock's account of Lintneri, one 

 or two points call for notice. Comstock says he found the ? reddish- 

 brown, witli the last segment yellow, but supposes in life it would 

 be reddish. This I doubt, but my specimens are not alive, so I 

 cannot say certainly what colour they originally were. In his table 

 of Chionaspis (2nd Cornell Rep., p. 98) he separates Lmtneri from 

 salicis by two characters : — 

 (i.) Distal ends of mesal lobes pointed or obscurely trilobed. 



They are not exactly pointed, and the trilobation is very obscure, 

 but the distinction intended seems a valid one. 

 In salicis these lobes are more truncate altogether. 

 (2.) A single plate laterad of each second lobe, and usually two plates 

 iaterad of each third lobe. 



This appears to break down altogether; the first specimen I 

 examined was as above described, with two and three plates ; but 

 the character was not constant, the next one looked at being 

 as typical Lintneri. 



On comparing the Charlottetown scales with scales of C. salicis 

 received from Mr. Newstead, I found that they were practically 

 alike. Comstock says he cannot tell the scales of Lintneri ($) from 

 salicis, — neither can I. 



If Comstock had not described Lintneri, I think I should have 

 placed the Charlottetown insect, for the present, as C. salicis, van; 

 but although it is extremely near to salicis, it must be admitted 

 that it is not really the same, and the name C. Lintneri stands valid. 

 Fortunately I had some scales of C. alni, Sign., sent to me by 

 Mr. K. Sulc, collected at Kralove Dvur, Bohemia. On comparing 

 them with the Charlottetown Lintneri, they were manifestly distinct, 

 being narrower, not so white, with paler exuviae. They were from 

 Alnus glutinosa. 



It may not be out of place here to call attention to Aspidiotus 

 betulce, Baren sp., 1849, which is listed in Prof. Smith's New Jersey 

 Catalogue. It is a pretty and distinct species, but I have seen only 

 European specimens.
