(Plate XXXV.) 



Chio7iaspis aspidistra, var. inusscs7tdcs, Green, ' Catalogue of Coccidas,' Indian 

 Mtiseum Notes, Vol, IV., No. i., p. 2 (1896). 



Female puparium very inconspicuous and difficult to detect, concealed by a 

 covering of the surface hairs {fig. 9), or fibres {fig. 8) of the bark, and con- 

 sequently varying in appearance according to the nature of the part of the plant 

 to which it is attached. Actual colour of the scale where not concealed by 

 the superimposed material greyish white. Form oblong oval, or dilated 

 behind. Pellicles very pale yellow ; the second usually concealed. Posterior 

 extremity of second pellicle with very prominent median lobes {fig. 13). 

 Length 2'So to 3*25 mm. Breadth i'5o to 175 mm. 



Male puparia snowy white ; strongly tricarinate {fig. 2) ; collected into 

 conspicuous groups {fig. 6), in which the individuals are crowded together, each 

 scale erect and attached by the anterior extremity only. When first formed they 

 are often densely covered with silky filaments ; but these afterwards fall off, 

 leaving the puparium fully exposed. Length about i"25 mm. 



Adult female of same form and general appearance as aspidistrce, but much 

 larger and more robust. Colour varying from yellow {fig. 10) to dull orange 

 {fig. 12) ; older examples with median area suffused with brownish red {fig. 1 1). 

 Margins of abdominal segments, and often those of meso- and meta-thorax, 

 with conspicuous lateral processes (_/?o-. 12). After oviposition the lateral pro- 

 cesses disappear {fig. 11). Margins of the segments with groups of oval pores, 

 and four to seven stout spiniform squames on lateral margins of second 

 and third abdominal segments. In the living insect the four spiracles are 

 marked by conspicuous white waxy patches secreted by the parastigmatic 

 glands. Pygidium {fig. 7), with median lobes large, prominent, and conspicuous, 

 their inner edges in close apposition, the free edge sloping and crenulate. Other 

 lobes obsolete. Squames stout, one on each of first to third spaces, two on 

 fourth space, and a group of five to seven on base. Dorsal pores as in aspidistra j 

 sometimes a double series on base. Circumgenital glands in five groups, with 

 numerous orifices : median 19 to 24 ; upper laterals 30 to 38 ; lower laterals 

 27 to 35 ; the upper laterals always with the larger number. Anal aperture 

 between the upper lateral groups, considerably above the level of the genital 

 orifice. Length of extended example v^o to 1*75 mm. Greatest breadth 

 075 mm. 



Adult male {fig. i), bright brick-red. Form normal. Antennae with a 

 single knobbed hair at extremity {fig. 5). Foot {fig. 4), with one tarsal and 

 one ungual digitule. Tarsus nearly as long as tibia. Length rather more than 

 I mm. 



Eggs and young larvae brownish red.
