R. NEWSTEAD — NOTES ON SCALE-INSECTS (COCCIDAE). — PART I. 79 



second pair with a deep lateral notch, third pair similar but smaller and with the 

 projecting lobe more or less angular. Squames narrow and divided laterally, but 

 scarcely fimbriated, one or two of the proximal ones being spiniform. Rudi- 

 mentary antennae furnished with a single and unusually long hair (fig. 10c). 

 Parastigmatic glands absent. Rostral filaments of great length in the young 

 adult, being, approximately, twice the length of the body. Sexual orifice 

 proximal. Anal orifice sub-marginal. 



Uganda : Tero Forest, 13. vii. 12 (C. C. Gowdey). 



" On an unknown shrub in depth of forest," in association with Lecanium 

 ( Eulecanium) filamcntosnm , Newst. The puparia (" scales ") were either attached 

 to the edges of the leaves or near the edge of an artificial perforation. 



The puparium of this Coccid is distinguishable by its dull crimson colour ; 

 the female by the lobe-like extension of the abdominal segment and the great 

 length of the hair on the rudimentary antennae. 



Described from two adult females and five puparia. 



Chionaspis unilateralis, sp. n. 



Puparium of adult female. — White and translucent ; very long and narrow, 

 sides parallel but not perceptibly flattened. Larval pellicle pale yellow ; margin 

 without spines ; second pellicle ochraceous or faintly darker than the rest of the 

 puparium. Ventral scale represented by a narrow strip attached to the margins 

 of the puparium. Length, 2*4-2'75 mm. 



Male -puparium. — White, distinctly tricarinate ; larval pellicle yellow, often 

 with a patch of dark colour centrally. 



Female, young adult (fig. 11a). — Elongate, with four of the abdominal segments, 

 on the left side of the body only (fig. Wb), very distinctly tuberculate ; of these 

 the second, third and fourth each bear a single huge spine-like squama ; in 

 addition to the latter the lobes are also provided with tubular glands, the third 

 tubercle having a well-marked transverse series of seven or eight (fig. lie) on 

 the dorsal surface. Pygidium (fig. lie?) with three pair of lobes, the median 

 pair being partly recessed and the free edge finely serrated ; second pair of lobes 

 simple and projecting beyond the first ; third pair narrowly separated from the 

 second. Marginal, cylindrical spinnerets large ; there are usually eight on either 

 side of the median lobes. Circumgenital glands in five groups ; the formula of 

 five examples is given below : —

Rudimentary antennae (fig. We) each with a very long curved spinose hair. 

 Parastigmatic glands absent ; but there is a series of short tubular spinnerets 

 extending from the lower right stigmen, these organs being entirely absent from 

 the stigmen on the opposite side. 



Female, old adult. — Much more elongate than the preceding and with normally 

 short rostral filaments. In all the other morphological details it does not differ 

 from the young adult,
