(Plate L.) 



Chionaspis eugenice, var. varicosa, Green, ' Catalogue of Coccidas,' Indian 

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



Female puparium {fig. 2) snowy white, opaque, of rather stout texture ; very 

 broadly and roundly dilated, so that the width usually equals the length ; 

 flattish, with the surface veined with irregular raised Hnes. Secretionary area 

 often completely surrounding the second pellicle. Pellicles pale fulvous, the 

 second tinged with red. Length 3 mm. Breadth 3 mm. Length of second 

 pellicle I mm. 



Male puparium white, pellicle very pale yellow. Oblong, narrow ; carinas 

 very feebly indicated {Jig. 4) ; surface often coated with fibrous secretion 

 {fig- 3)- Length 175 mm. 



Adult female {figs. 5, 6, 7) pale yellow, pygidium reddish. Form oblong ; 

 broadest across mesothorax ; segments rather protuberant. In the living insect 

 very faint rudiments of eye-spots can be seen. Anterior spiracles with con- 

 spicuous parastigmatic glands. Margin of meso and metathorax and all three 

 abdominal segments with groups of small conical squames intermixed with oval 

 pores. Pygidium {fig. 8) with a broad and deep median cleft containing the 

 rather large divergent median lobes, their free edges minutely serrate. Second 

 and third lobes well developed, duplex, each lobule very prominent, with 

 rounded extremity and constricted base, projecting considerably beyond the 

 margin. Squames spiniform ; one on each of first to third spaces, usually 

 three on fourth space, and a group of four to seven on base. Dorsal pores 

 numerous : a group of two or three on third space, large series on fourth and 

 basal spaces, and still larger, often double, series on second and third abdominal 

 segments. Circumgenital glands in five groups ; orifices numerous ; median 

 group 10 to 16 ; upper laterals 23 to 27 ; lower laterals 27 to 60 ; the lower 

 groups always the larger. Anal anterior to genital aperture. Length i"5oto 

 2 mm. Breadth 075 mm. 



Adult male bright reddish orange. Form normal. Terminal joint of 

 antenna with knobbed hair at apex {fig. 9). Tarsus a little shorter than tibia. 

 Foot {fig. 10) with three digitules, one ungual and two tarsal. Length including 

 genital sheath i mm. 



Eggs and young larvae yellow. 



Habitat on the under surface of leaves of Gelonium lanceolatum. Pundaluoya. 

 The female scales are usually placed close to the mid rib or veins. The males 

 are clustered on the interspaces between the veins {fig. i). 



Mr. Maskell considered this to be a variety of his Ch. eugenics, but examination 

 of an extensive series of specimens inclines me to believe that the species is 

 distinct. In typical eugenice the pygidium is broader and rounder, the median
