Female puparium {Jigs. 2 and 7) composed almost entirely of the oblong 

 second pellicle, covered with a thin transparent layer of colom-less secretion, 

 which extends very slightly beyond its margin. The first pellicle is very small, 

 pale straw colour, and situated at the anterior extremity, projecting beyond 

 the margin. Colour of second pellicle dull reddish fulvous ; median area 

 darker, sometimes forming a well-defined longitudinal stripe {fig. 7), which is 

 intensified by the presence of a more or less prominent median ridge. The 

 posterior margin of the second pellicle {fig. 8) is similar to that of the pygidium 

 of the adult female. The puparium is closed beneath by a transparent mem- 

 brane, which is the ventral portion of the second pellicle. The adult insect 

 occupies the anterior portion of the scale, the hinder portion being packed 

 with the pale yellow eggs arranged in two rows. Length about 1*25 mm. 

 Breadth 0*50 mm. 



I have not observed the male puparium of this species. Signoret describes 

 it as being similar in structure and appearance to that of the female, but smaller 

 and narrower. This must surely be a mistake. In all the allied species the 

 male scales are snowy white, and usually tricarinate as in Chionaspis. 



Adult female {fig. 3) fiattish, marginal area especially thin ; abdominal 

 segments (after oviposition) very much contracted, their lateral margins over- 

 lapping the base of the pygidium. Signoret describes the insect as very elon- 

 gated, three times as long as broad. This must refer to the early adult stage, 

 when it would almost fill the puparium. Colour pale yellow ; median abdominal 

 area reddish brown. In the living insect minute black eyes are visible close to 

 the margin. The rudimentary antennre {fig. 5), situated in a median depression 

 on the anterior margin, are apparently two-jointed, the basal joint consisting of 

 a broad fleshy tubercle bearing a stout curved bristle on one side, the second 

 joint taking the form of a stout pointed spine, which in some specimens bears 

 a small lateral point near the extremity {fig. 6). The margins of the abdominal 

 segments bear a few spinous tubercles {fig. 4). Pygidium {fig. 4) deltoid ; 

 apex rather truncate, with a distinct median notch, the sides of he notch 

 occupied by the oblique median lobes, which are finely serrated along their
