ing character of this species. In some others the unity of the lobes 

 appears complete, as Chionaspis quercHs, Comstock, and Aspidiotus 

 unilohis, Maskell ; but the greater number have the line of separation 

 visible. 



Chionaspis nerii, n. sp. 

 $ old adult ovate, widely rounded in front and behind. The anterior group of 

 spinnerets consists of from 16 — 19, the anterior laterals 17 — 33, the posterior laterals 

 13 — 29. The marginal fringe (fig. 1) has the median lobes very broad, widely 

 separated ; second pair much smaller, with or without slight marginal indentations ; 

 third pair triangular, but almost obsolete. There are two very small spines below 

 the median lobes, and one or more nearer the base of the pygidium ; the first two 

 plates overlap the outer margin of the median lobes, between the second and third 

 lobes are three large plates, beyond these are two groups of five or six more. Within 

 the margin on either side of median lobes are several short spines. Beyond the grouped

spinnerets are numerous pores arranged in three broad interrupted bauds, widest at 

 margins. The rudimentary antennae are furnished witli a single strong spine, and 

 one or more exceedingly small pointed prominences (? spines). Abdominal and 

 thoracic segments widely at margins and subdorsally with numerous short spines 

 and pores. 



Scale of the ? white, anterior portion sometimes dusky or straw-coloured. 

 Larval and second moult more or less yellowish-white tinged with pale brown ; the 

 second moult distinctly raised, convex, and projecting beyond the scale. Ventral 

 scale white, very thick, complete. 



Long, 1-75— 2-25, wide, lo— 2 mm. 



Scale of <J , together with larval moult, white. I am unable to state whether 

 carinate or not, as the only example is badly broken.
