the close relationship of this species to his convexus, but having described 

 and figured the adult female of the latter from ancylus, the fact of the 

 identity of the two was obscured. 



The scale material which we have determined as convexus must, 

 therefore, now be referred to cydonice, Comst. The name convexus 

 becomes a synonym of both camellice and ancylus, since the covering 

 scale was described from material representing the former, and the 

 female insect from material representing the latter, species. 



Aspidiotus cydonice, Comst., has been three times since described 

 as distinct by Prof. T. D. A. Cockerell, his species Crawii, punicce, 

 and his variety lateralis of Newstead's species diffinis belonging to 

 cydonice. The error in referring " lateralis " to diffinis was doubtless 

 occasioned by the fact that the material from which the variety was 

 described for the most part represented immature females, judging from 

 an examination of part of the type material deposited in the National 

 collection. 



The cydonicB recognized by E. E. Green in Ceylon (Coccidie of 

 Ceylon, I., p. 62, PI. XIV.), and afterwards made the type of Greenii by 

 Cockerell, was correctly placed by Green. I may add that the material 

 in the National collection determined by Professor Cockerell as Greenii 

 is a mixture of camellice and cydonice. The material on banana collected 

 by Mr. Townsend in Mexico (7857) is referable to cydonice, and also the 

 palm scale collected by Cockerell at Mesilla, N. Mex. The scale on 

 Japanese palm collected at Mexico City, Mex., December 6th, 1897, is a 

 mixture of cydonice and camellice in the proportion of about 3 to i, 

 judging from a single slide mount which contains three females of 

 cydonice and one of catnellice. 



The synonymy of the two species, cydonice. and camellice, is as 

 follows :
