(83). Aspidiotus picnicce, Ckll. (The pomegranate Aspidiotus). 



Diagnosis. — A small white scale, with a small shining orange-brown 

 boss. The scale is rather like rapax, but not so convex, and of a 

 different colour. 



Distribution. — Jamaica, Dominica, Brazil, and in a hothouse in Wash- 

 ington, U.S.A. 



' Food-plants. — Originally found on pomegranate, but more frequently 

 observed on palms. 



Destructiveness. — It would be destructive if abundant. 

 (84.) Aspidiotus diffinis. — Newstead var. lateralis, Ckll. 

 This a scale found on Jasminum in Jamaica, which may prove to be 



only a variety of punicce. The scale is convex, brownish-white to 

 brown. The typical diffinis is from Demerara. 



(85). Aspidiotus hotcreyi, Ckll. (Bowrey's Aspidiotus). 

 Diagnosis — Small elongate gray scales, with a blackish spot towards 

 one end. 



Distribution. — Only known from Hope, Jamaica, where it was disco-vered 

 by Mr. Bowre3\ 



lood-plant, — Agave rigid a. 



Destructiveness. — The scales occur crowded on the plant, and must be 

 harmful. 



This ends the series of West Indian Coccidae, except a few species dis- 

 covered since the genera they belong to were discussed, which will be 

 described in a supplementary article.

Very plentiful in forests at 5000-6000 ft. alt. on decaying logs and 

 other substance on the ground. This was first ascribed to A. Sartorii, 

 Lieb. from which it appears to be distinct. In shape of frond it re^
