440 Monophlebin(2. 



occasional examples may attain a length of 6 mm., and I have observed fully 

 matured females measuring little more than 3 mm. in length. 



Nymphal stages similar to adult, but with smaller and less-pronounced 

 processes. Antennas six-seven jointed. 



Young larvce (,fig. 2) pale pink, thickly dusted with white meal ; legs and 

 antennce very pale brown. Antennae six-jointed, with long hairs. Posterior 

 extremity with six long radiating setae. 



Adult male {fig. 14) brownish red ; the metatergal and metasternal plates 

 blackish. Legs and antennce dark brown. The whole body dusted with 

 whitish meal, which is aggregated into loose tufts on the sides of the abdomen. 

 Wings fuliginous, with a greyish bloom ; costal nervure reddish, second nervure 

 black ; interneural folds white ; membrane with minute transverse corrugations. 

 Eyes prominent, compound. A single prominent ocellus slightly behind each 

 eye. Antennas long and moderately slender ; ten-jointed, each joint (except the 

 basal two) with two prominent thickened nodes {see fig. 15), from which spring 

 whorls of long hairs. Posterior extremity with a pair of stout wrinkled fleshy 

 appendages, each bearing at its extremity six or seven longish setas. Total 

 length (including appendages) 3 mm. 



An abundant and widely spread species, occurring throughout the island on 

 numerous plants, amongst which may be mentioned Acalypha, A?iona, 

 Braga7ttia, Codicpum, CuUenia, Mo?i(i}ioa, Palms, Fsidhun, Rose, Tea, 

 Sirobilanthes, &c. Often present in such masses as to endanger the health of 

 the plant, but not— at present — reported as a pest of economic importance. 

 Recorded first from Egypt ; but ranging throughout the Eastern Tropics.

Adult female orange red or brick red, obscured by a granular covering of 

 waxy secretion which may be either bright canary yellow {figs, i, 2) or white 

 tinged with yellow {fig. 4). The bright yellow colour is more usual in the 

 younger individuals, though it may be retained in the later stages. Interspersed 

 with the granular secretion are numerous long silky tubular filaments. Legs, 

 antenna;, and eyes black. The secretionary matter is aggregated into short 

 tufts or tassels, of which there is a median longitudinal series on the dorsum 

 and a more or less complete marginal series, the latter being duplicated on the 

 abdominal segments. Finally, a well-developed ovisac is produced from below
