r Enemies. — Fortunately it [suffers a good deal from the attacks of 

 Dipterous parasites. 



(39) . Puhinaria dendrophthorw, Ckll. (The Mistletoe Cottony-scale). 

 Diagnosis. — A small elongate-oval greenish scale, producing a white 



cottony ovisac. Unfortunately with one exception all the specimens of 

 this insect examined were without ovisacs and somewhat immature. It 

 is by no means certain, notwithstanding some small differences observed,, 

 that this is anything more than a slight variety of P. cupanice. 



Distribution. — Only known from Cinchona, Jamaica, where it was 

 collected by Mr, Fawcett. 



Pood-plants. — Found in great numbers on Dendrophthora cupressoides- 

 Destructiveness. — Of no observed economic importance. 



(40) . Puhinaria urbicola, Ckll. (The Capsicum Cottony Scale). 

 Diagnosis. — An oval skiny pale brown scale; producing a white 



ovisac which is depressed, parallel-sided fairly firm, somewhat inclined 

 to be longitudinally ribbed, — instead of being convex, loose and fluffy 

 as in cupauiw. Length with ovisac over a quarter of an inch. 



Distribution . — The only known locality is the yard of Manchester 

 Cottage, Kingston, Jamaica, where it was found first in September 

 1892. 



Fo d-plants. — It occurs on Capsicum infesting the stems and under 

 sides of the leaves. 



Destructiveness. — Apparently of very small economic importance. 



Enemies — Like P. cupanice, it suffers severely from Dipterous 

 parasites. From only four P. urbicola I bred, in December 1892, 

 thirty-two Dipiosis coccidarum. 



(41). Pulvinaria Simula ns, Ckll. (The Trinidad Cottony-Scales. 



Diagnosis. — A small species, with a snow-white, depressed, parallel- 

 sided, closely felted, not ribbed ovi-ac. Smaller than the last species. 



Distribution. — Only known from Port-of Spain, Trinidad, where it 

 was found by Mr Urich. 



Fooa '-plants. — Found on the leaves of a tree not identified. 



Destructiveness. — .Not known as a serious pest. 



Enemies. — It has a chalcidid parasite. 



Subgenus Protopuhinar ta. 



This subgenus was proposed for the reception of P. pyriformis, 

 which is a small, flat, pyriform or subtriangular reddish-brown scale, 

 producing only enough cottony matter to project as a sort of fringe 

 round the hind margin of the scale. 



(42). Pulvinaria pyriformisy Ckll (The Primitive Cottony-Scales). 



Diagnosis. — See above under the subgenus. 



Distribution. — Found in St. Ann's, Trinidad (Urich), in the Botanic 

 Gardens, Grenada (Broadway), and at Mr Schloss's Pen at Half-way 

 Tree, Jamaica. 



Food-plants. — In Trinidad on guava ; but in Grenada in some 

 quantities on leaves of cinnamon. Also on cinnamon in Jamaica, the 

 latter specimens being formerly recorded in error as Lecanium 

 mai/giferce, which is common in Jamaica, and which they much 

 resemble. 



Destructiveness. — It may prove troublesome on cinnamon.
