yellow, tipped with brown. The antennae and feet are normal. 

 Fore wings with three bands of dark-brown, of which the outer 

 one does not quite reach the margin at the extremity. The 

 genitalia do not exhibit any special features. 



Hah. In Ceylon, on Piper {nigrum ?). My specimens were 

 sent by Mr. E. E. Green, from Punduloya. 



I know^ of no described species in which the larva and 

 pupa have such strong black spines as this. The wings of the 

 adult are not particularly distinctive, for those of A. sacchari, 

 Mask., 1889, have quite similar bands. I have found it ex- 

 tremely difficult to correctly distinguish the dorsal spines on 

 the pupa ; and the vasiform orifice also presents much diffi- 

 culty.

48. Aleurodes pulvinata, Maskell, sp. nov. Plate XXXIV.— 1. 



Larva not observed. 



Pupa-case dark-orange, with two broad lateral longitudinal 

 bands of dark-brown, which do not touch the margin, and 

 \Yhich denote the enclosed insect. Form roundly elliptical, 

 the cephalic extremity sometimes slightly depressed ; dorsum 

 slightly convex ; abdominal segments moderately distinct. 

 Length about -^-Q\n. The dorsum bears, some distance within 

 the margin, a series of twenty-two tubercular pores, glands, 

 or spinneret orifices. Of these, four on the extreme cephalic 

 region are small, with simple circular orifices ; the next two 

 (one on each side), on a level with the rostrum, are large and 

 conspicuous, consisting of a cylindrical tube with wide circular 

 orifice ; the next four (two on each side) on the median 

 thoracic region are rather small, but larger than the anterior 

 cephaUc ones, and have circular multilocular orifices ; the 

 next eiglit (four on each side) on the abdominal region are 

 similar to the two large ones near the rostrum ; the last 

 four (two on each side) near the abdominal extremity are 

 about equal in size to the four on the cephalic region, and 

 are simple. The margin is very finely striated, but not 

 crenulated ; and for some distance wnthin it the dorsum
