Mytilaspis. 85 



MYTILASPIS GLOVERII, Packard, var. PALLIDA, Green. 



(Plate XXIU.) 



Mytilaspis pallida, Green, ' Catalogue of Coccida;,' Ind. Mus. Notes, 



Vol. IV. No. I. (1896). 



Female puparium {figs. 3 and 4) very pale straw colour, with a broad 

 colourless flattened border which extends round the pellicles. Ventral scale 

 broadly divided, showing the eggs disposed symmetrically in two rows. Length 

 3 to 3"5o mm., of which the pellicles occupy rather less than one-third. 

 Breadth o'8o mm. 



Male puparium {fig. 2) with broad flattened margin. The hinge-like struc- 

 ture is not so conspicuous as in the previous species, but the scale posterior to 

 that part is of a darker, more fulvous tint. Length i'5o mm. 



Adult female {fig. 8) creamy white, extremity reddish fulvous. The three 

 last abdominal segments each with three or four short stout marginal spines. 

 Abdominal segments rather more chitinised than the anterior parts. I find the 

 number of orifices in the circumgenital glands to be very constant ; median 

 with 3 widely separate orifices, upper laterals with 7 or 8, and lower laterals 

 with 4 only. Length i to r25 mm. 



Adult male {fig. 5) pale purple ; head darker ; legs pale yellowish ; dorsal 

 plates of mesothorax pale and tinged with reddish. Anterior parts of the body 

 elongated. Terminal joints of antenna with three knobbed hairs {fig. 7), one 

 at apex and two at side, the latter very fine. Tarsus shorter than tibia. Foot 

 with three knobbed hairs {fig. 6), the one on claw longest. Length o"62 mm., 

 of which the genital spike occupies one-third. 



Habitat on leaves of various unidentified shrubs. Punduloya, Kandy 

 (January). 



The difference between this insect and typical M. gloverii seems scarcely 

 sufficient to justify its specific separation, but the colour and structure of the 

 puparium— especially the very wide flattened border — incline me to rank it 

 provisionally as a well-marked variety.
