form joints 3, 4, 5 and 6 are approximately equal. Legs very small and feeble : 

 tarsus approximately equal to tibia (fig. 3, a) : digitules filiform, minutely knobbed 

 at extremity. No anal lobes, the posterior extremity evenly rounded. Anal ring 

 fig. 3, b) circular or oblate, bearing six short and inconspicuous setae united by a chain 

 of ceriferous pores. J)erm with small and inconspicuous circular pores, on the 

 posterior segments only. Diameter of fully matured examples 3'50 to 4"0 mm. 



Early adult female (containing developing embryos) very much smaller, scarcely 

 one-eighth the size of fully matured individuals : longer diameter 1*50 mm. At this 

 stage the insect is subspherical in outline, the anterior extremity produced into a blunt 

 point. The junctions of the abdominal segments, in these younger females, are often 

 marked by series of irregular thickened ingrowths of the derm. 



I have been unable to recognise the true nymphal stage. All the smaller examples 

 examined contained developing embryos. 



Larva oblong oval. Antenna 6- jointed : the joints rather contracted in the newly 

 hatched insect (fig. 3, c), more elongated in the later larvae (fig. 3, d). Posterior 

 extremity (fig. 3, e) with the anal lobes scarcely prominent : their position indicated 

 by short setae. Anal ring with six slender setae which are relatively longer than in 

 the adult insect. Derm with scattered circular pores and very short hairs.

On Pinus longifolia, Kumaon Himalayas ; and on Pimts excelsa, Kamraj Division, 

 Kashmir. 



The living insect is said to occupy gummy (? resinous) cells on growing shoots of 

 the plant. 



Mr. C. F. C. Beeson, Forest Zoologist, Dehra Dun, supplies the following notes 

 descriptive of the colour of the living insect : — 



" Colour of adult female, during gestation, reddish ochreous, with a smooth glossy 

 surface. After extrusion of the eggs the colour passes to reddish brown and finally 

 to brownish purple, the surface becoming dull and wrinkled. 



" Colour of egg lemon yellow ; surface ' matt,' owing to closely adherent white 

 mealy powder.
