PROFESSOR R. NEWSTEAD — NOTES ON 



articulated. Free abdominal segments well defined. Cephalo-thoracic area with 

 many large and widely separated hairs. There are 9-18 parastigmatic glands 

 just in advance of the anterior stigmata ; their presence at the lower pair of 

 stigmata is doubtful. Pygidium (fig. 5b) with three pairs of tricuspid lobes : 

 central pair much the largest and also much more distinctly tricuspid ; second 

 and third pairs narrow, but well developed. Squamae strongly bifurcated 

 distally. Spines long and rather stout. Dorsal surface of pygidium with a 

 large and somewhat pyriform reticulated area, the reticulations small and 

 irregular. Circumgenital glands absent. Tubular spinnerets short, pores large 

 and arranged more or less in definite linear series. 



Parasitised females (fig. 5c) much larger than the normal individuals and the 

 integument highly chitinised and distended.

Diaspis boisduvalii, Sign., occurred in association with this Coccid, but the 

 puparia of the latter were not fixed near the mid-rib of the leaves. 



This insect is closely allied to Aspidiotus (Pseudaonidia) trilobitiformis, Green, 

 but is distinguished by the colour of the puparia ; and in the female by the 

 absence of circumgenital glands, and also by the character of the fourth pair of 

 lobes to the pygidium. 



Aspidiotus (Pseudaonidia) fossor, sp. n. 



Female puparium sub-circular, highly convex, black or piceous, very thick and 

 strong, but invariably covered with a superficial layer of bark, so that it is
