1897.] Q9 



The plants at the Gardens are too well tended and looked after 

 to harbour many insect pests, but my day's collecting produced six- 

 teen distinct species, five of which (as I am informed by Mr. Newstead) 

 are new to the British lists. These are, of course, introduced species, 

 and are likely to occur only in plant-houses ; but no catalogue of the 

 British Coccids would be complete without those species affecting 

 plants under glass. 



The following is a list of my captui'es at Kew. In giving the 

 name of the host-plant, I have mentioned the country from which it 

 comes ; but it must not be supposed that the parasite has in every 

 case been imported with the plant. In many cases the Coccids have 

 doubtless strayed from neighbouring plants ; and some species are 

 practically omnivorous. 



AspiDiOTUS ALOES, Boisd. — On a plant of Agave Palmer i I found 

 a colony of insects answering well to Signoret's description of A. aloes. 

 The scales were, however, very light straw colour instead of white. 

 The insects were crowded on the bases of the leaves, and had insinu- 

 ated themselves within the yet unfolded leaf buds. This species has 

 not previously been recorded from the British Isles. 



AspiDiOTUS Picus (Riley). — A young tree of Garcinia camhogia 

 (the gamboge tree), labelled from Ceylon, supported a large colony of 

 these insects. ^ and ? scales, in all stages, were present on both 

 surfaces of the leaves. Prof. Comstock quotes this species as an 

 injurious pest on young orange trees in the United States. 



[Abundant also on Lonchocarpus Barteri, Benth., and Eugenia 

 malaccensis, L. — R. N.] 



AspiDiOTUS NEBii, Bouche. — A few specimens of this insect were 

 found on the fronds of a palm, Aristea major (from Madagascar). 



AspiDiOTUS PEESONATUS, Comst. — This species occuri-ed in abund- 

 ance on Tillandsia corallina (from Brazil) and Tillandsia confertijlora. 

 The small, highly convex, black scales, and the curious lobe at the 

 cephalic extremity of the $ , make it impossible to mistake this insect. 

 It has not previously been recorded from the British Isles. The 

 original examples, described by Prof. Comstock, came from Cuba. 



PiNNASPis PANDANi, Comst. — A few small scales collected on 

 Pandanus conoideus (from Malay) appear to belong to this species, 

 but the material was insufficient for a satisfactory determination. 

 There seems to be some question as to the possible identity of P. 

 pandani, Comst., with Mytilaspis huxi, Bouche. With respect to 

 Prof. Comstock's name for the species, I note that in his Agr. Report,
