The pupa-case, in the earliest stage, scarcely distinguishable from 

 the late larva; afterwards as the insect grows, it becomes much thicker. 

 The form remains elliptical; the length reaches about one- thirtieth 

 in. The dorsal disk is slightly convex, flattened towards the margin ; it is 

 larger than the ventral disk, and slightly overlaps the sides, which are 

 vertical. The hollow thus formed is covered by a ring of thin white 

 wax, and there is also a plate of wax beneath the ventral surface ; por- 

 tions of this ring and of the plate are frequently seen amongst the long 

 threads of the larva. The pupal margin is crenulated, but bears no 

 fringe, and the dorsum has no pores or wax. The outline of the enclosed 

 pupa may be made out indistinctly on the dorsum, and the rudimentary 

 organs ventrally on turning over the case. Vasiform orifice subcorneal, 

 with regularly convex sides, the anterior edge concave; operculum sub- 

 elliptical ; lingula very short, not extending beyond the operculum. 



Adult form unknown. 



Hub. In India, on Ecsa. My specimens were sent by Mr. Cotes, 

 late of the Indian Museum Calcutta. They came from Quetta, Baluchis- 

 tan. I have named the species after him. 



The overlapping of the sides by the dorsal disk of A. cotesii is found 

 also in a New Zealand species, A. fagi, Maskell, 1889 ; but that insect has 

 no fringe, the margin bears twenty-four hairs. 



Aleurodes piperis, Maskell. 



Trans., N.Z. Inst., Vol. XXVIII, 1895, p. 438. 



Eggs dark-yellow, elongate-elliptical, transversely striated ; length 

 about one-one hundred and forty-fifth in. 



Larva very dark-brown or black, very slightly convex, elliptical ; 

 length about one-fortieth in. Dorsum bearing long, very black spines 

 of which four are on the cephalic, eight on the thoracic, and ten on the 

 abdominal regions. Margin not thickened, but very distinctly crenulated 

 There seems to be no fringe. 



Pupa-case intense glossy black, slightly convex, with a median longi. 

 tudinal ridge ; abdominal segments indistinct. Form elliptical ; length 

 about one-twenty-fifth in. Dorsum bearing many long black spines, of 

 which one series of from twenty to twenty-four are submarginal, the 

 others scattered (seemingly about twenty, but very difficult to make out on 

 account of the intense black colour) ; two of the spines, at the posterior 

 extremity, are longer than the others. Margin with very small crenula- 

 tions ; there is a very short fringe of white wax, which in many specimens is 

 not noticeable. Vasiform orifice broadly rhomboidal with rounded angles, 

 anterior edge slightly concave ; operculum semi-elliptical, covering about 

 half the orifice ; lingula short, roundly clavate. The larval exuvia? are 

 commonly seen attached by the dorsal spines to the pupa-case. .
