amining the host after immersion in soda. It is interesting to find that this A. 

 pahna>, though away from its normal food-plant, was either followed by one of its 

 parasites or attacked by one that preys on other Diaspinse which infest the Banana. 



(33) MeJicocca lijuga L. (Sapindacese). — In Kingston I find on the upper side of 

 leaves of Genip, Ceroplastes floridensis, Aspidiotus personatus, and ^. articuJatus. 



(34) Phoenix daciylifera (Palmacese). — A tree in the Parade Garden, Kingston, 

 March 1, was very much infested by the fungus Grax^hiola phccnicis, which seems to 

 prevent Coccids from attacking the tree. I found only some very young scales, ap- 

 parently Aspidiotus articidatus. 



(35) Sahal (Palmaceae). — S. palmetto and S. umhracuJifoJia at the Parade Garden^ 

 Kingston, March 1, had a few Aspidiotus articulatus and A. personatus on the leaves. 



(36) Thevetia neriifoUa (Apocynacese). — At the Parade Garden, Kingston, has Aspi- 

 diotus personatus and A. articulatus on upper side of leaves. 



(23b) Vitis vinifera L. (Ampelidacese). — On a grape-vine in Kingston I found a 

 little colony of Chionaspis, $ and 9 , infesting the upper side of a leaf. These were 

 no doubt C. minor Mask., though I could not find a $ to examine, although there 

 were scales. Eggs orange, numerous. ^ scale rather longer jjerhaps than usual in 

 minor. Many mites among the scales. 



(30b) Hibiscus (Malvaceae). — In Kingston I find colonies of Chionaspis minor, $ and 

 2 , on upper sides of the leaves. They turn the leaf yellow at the place attacked. 

 The body of an adult 2 is strongly sufi\ised with verdigris-green, and some of the 

 eggs are verdigris-green. Is this a parasitic growth, like that referred to in '^ The 

 Microscope," by Jabez Hogg (12th Ed., 1887), p. 605. ? 



(37) Bignonia magnifica (Bignoniaceae). — A plant growing at Cavaliers, Kingston^ 

 presents one scale of Aspidiotus articulatus on upper side of a leaf; on the under sides, 

 of the leaves are a few Aspidiotus ficus, and plenty of Pulvinaria cupaniw Ckll., with 

 Biplosis pupa-shells projecting from the ovisacs. 



(38) Calotropis procera, R. Br. (Asclepiadacese). — A plant at the Parade Garden, 

 Kingston, September (Da Costa), has a very few Aspidiotus personatus on upper side 

 of leaves; but on the stems very many Diaspis lanatus Ckll. 



(39) Jasminum puhescens (Jasminaceae). — At the Parade Garden, Kingston, Septem- 

 ber (Da Costa) ; on upper side of leaf a great many Aspidiotus personatus^ with a. 

 few A. Hens, and one or two A. articulatus. On under side of leaf, a iew A. personatus. 

 On the stem, Aspidiotus n. sp., and bright red mites with very long hairs at the en da 

 of first pair of legs. 



(39b) Jasminum samhac. — At the Parade Garden, Kingston, September (Da Costa) ; 

 on upper side of leaves many Asjyidiotus articulatus ; on under side specimens- 

 of a small pale brown Lecanium, which, although diftering a little from the usual 

 form in appearance, can only be referred to L. mangiferw Green, on account of their 

 blunt-pyriform or subtriangular shape, and the branched hairs round the margin. 

 With reference to this and the last host-plant it is interesting to note that two plants, 

 of the same genus, from the same garden, are not affected in the same way by Coccidae. 



(40) Lawsonia inermis (Lythraceae). — At the Parade Garden, Kingston, September 

 (Da Costa) ; on upper side of leaves, many Aspidiotus articulatus and A. personatus;' 

 on under sideof leaves, 2 black ^?e^ro^e.s scales, 2 Aspidiotus ficus, and 1 A. personatus. 

 I also found on the leaves some young individuals of Ceroplastes. 



(41) Psidium guava Radd. (Myrtacese). — On a guava tree in Kingston, January 29, 

 I found Dactylopius longifilis. 



(42) Gossypium harhadense L. (Malvaceae). — On February 26, in Kingston, I found 

 many Dactylopius virgatus Ckll. n. sp. on under sides of leaves of Cotton. Two males, 

 were found; the $ of this species appears brown examined after death by trans- 

 mitted light, but seen alive it is dark olive-gray, with the caudal filaments white,, 

 and the wings shining iridescent red-purple. D. virgatus occurs on several plants in 

 Kingston, and is a very destructive species. The $ has fairly long caudal filaments, 

 but lacks the lateral filaments of longifilis. A full description of it will be published 

 elsewhere.
