amining the liost after iiiiraersion in soda. It is interesting to find that this A, 

 palmn; though away from its normal food-phxut, was either followed by one of its 

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



(33) 2feUcocca hijuga L. (Sapindace.-e).— In Kingston I find on the upper side of I 

 leaves of Genip, Ceroplastes floridennis, Aspidiotus jyersonatus, and A. ariicuJatus. 



(34) Phoenix daclylifera (Palmacea;). — A tree in the Parade Garden, Kingston, 

 March 1, was very much infested by the fungus Graphiola phocnicis, which seems to 

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

 parently Aspidiotus articulatus. 



(35) Sabal (Palmaceie). — S. palmetto and S. umhraciiUfolia at the Parade Garden^ 

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



(36) Thevetia neriifolia (ApocynaceiB). — At the Parade Garden, Kingston, has Aspi- 

 diotus personaiua 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 9 to examine, although there 

 were scales. Eggs orange, numerous. $ scale rather longer perhaps than usual in 

 viinor. Many mites among the scales. 



(30b) Hibiscus (Malvacea?). — In Kingston I find colonies of Chionaspis minor, <? and 

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

 The body of an adult 9 is strongly sutfused 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 viagnifica (Bignoniacese). — 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 cupanicB Ckll., with 

 Biplosis pupa-shells projecting from the ovisacs. 



(38) CaJotropis procera, R. Br. (Asclepiadaceje). — 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 pubescens (Jasminace;?). — At the Parade Garden, Kingston, Seiitem- 

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

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

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

 of first pair of legs. 



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

 on upper side of leaves many Aspidiotus articulatus ; on under side specimens 

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

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

 blunt-pyriform or suljtriangular 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 Coccidse. 



(40) Lawsonia incrmis (Lythracese). — 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 ^?ey>-odcs scales, 2 Aspidiotus ficus, and 1 A. personatus. 

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



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

 I found Dactylopius longifilis. 



(42) GossypiKm barbadense L. (Malvacec-e).— 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 9 has fairly long caudal filaments, 

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

 elsewhere.
