As my specimens agree exactly with Mr. Newstead's description 

 (loc. cit.) I take the liberty of reproducing his description of the 

 external characters. " Female puparium somewhat ovate but sud- 

 denly narrowed posteriorly ; widest and very highly convex in the 

 region just behind the larval pellicle. Colour varying from pure white 

 to smoky grey ; the secretionary matter is pure white, but when the 

 layer over the exuviae of the second stage female (second pellicle) 

 is thin, the dark colour of the imderlying insect shows through, giving 

 the puparium a smoky grey tinge. Overcrowded examples of the 

 puparia become distorted and irregular in shape as in other DIASPIN^ 

 under similar conditions. Larval pellicle usually ochreous buff, often 

 with a small bottle green spot at the caudal extremity. Second 

 pellicle piceous or dark castaneous, sometimes with a dull crimson 

 area in the centre ; the colour is, hovewer, very variable. 



Length 1-75-2 millimetres. 



Male puparium relatively large, sides more or less parallel, convex 

 for the greater part, but with the posterior extremity flattened. 

 Pellicle usually bottle green, but a few examples are dull greenish 

 yellow ; in some instances they occupy an almost oblique position ; 

 in others they are parallel with the secretionary portion. Normally 

 they are straight, but in a very large percentage of cases they are 

 curved or contorted owing chiefly to overcrowding or to the nature 

 of the bark upon which they are fixed.
