CHIONASPIS ALBIZZI^, sp. nov. 

 (Plate XXXIV.) 



Female puparium opaque snowy white, often specked with brown {fig. 2) 

 from the incorporation of fragments of the cuticle of the bark : rather broadly 

 dilated behind. Pellicles fulvous, the second deeply tinged with reddish brown. 

 In fully developed examples the second pellicle occupies a little less than one-, 

 third the length of the puparium. First pellicle half length of second. Ventral 

 scale thin, remaining attached to plant. Length rjo to 2 mm. 



Male puparium {figs. 8, 9) snowy white ; narrow, sides almost parallel, 

 posterior extremity slightly wider ; distinctly tricarinate ; the ridges even and 

 moderately smooth. Pellicle fulvous. Length i mm. 



Adult female {figs. 3, 4) oblong, broadest across the abdomen ; abdominal 

 segments distinctly marked, with prominent lateral margins. Colour at first 

 clear reddish orange, afterwards becoming darker from the accumulation of the 

 contained ova, giving the insect a deep purplish tinge in the middle {fig. 3) : 

 older examples become more or less uniformly purplish brown. Antennae with 

 a single longish curved bristle. Minute reddish eye-spots can usually be dis- 

 tinguished in the living insect, situated on small marginal prominences. 

 Anterior spiracles with a small group of parastigmatic glands. A few pores on 

 lateral margins of metathorax and each of the abdominal segments. A group 

 of three or four spiniform squames on second and third abdominal segments. 

 Single squames on first to fourth spaces of the pygidium, and two or three on 

 the base. Median lobes of pygidium prominent, their inner edges in close 

 apposition {fig. 6) ; emarginate, slightly truncate at extremity. First lateral 

 lobes minute but prominent. Second lateral lobes almost obsolete, their 

 position indicated by a serrate thickening of the margin. The usual marginal 

 pores. Dorsal pores few ; a double series, consisting of five or six, on the base 

 of the pygidium, and a single pore on the fourth space. Circumgenital glands 

 in five groups ; median with 6-1 1 orifices ; upper laterals 14-17 ; lower laterals 

 12-17. Genital aperture about the middle of the pygidium ; anal orifice slightly 

 nearer the extremity. Length of extended example i to ri2 mm. 



Adult male bright red ; a prominent dark spot on genae representing the 

 rudimentary eyes {fig. id). Terminal joint of antenna with single knobbed hair 

 at apex. Foot with two digitules, one ungual and one tarsal. Length about 

 I mm. 



The early scale of the female (of second stage) is thin and semi-transparent, 

 showing the colour of the insect through it {fig. 7) ; the surface closely frosted 

 with white specks. 



Egg {fig. 5) oblong, frequently distorted and unsymmetrical ; reddish or 

 brownish-purple. 



Habitat on stems of Albizzia stzpidata and allied species. Also on 

 Pithecolobiuvi sainan. Occurring often in such numbers that the whole surface
