ed with a similar gelatinous secretion. This is secreted from a large 

 number of very minute pores which appear to lie all over the dorsum 

 without any definite grouping. Colour of secretion yellow. Two setae, 

 one on each side of incurved caudal area. Parasited pupae are smaller 

 than nonparasited pupae, are darker in colour and have the dorsum 

 much arched. The developing parasite can be easily distinguished 

 within the body. 



Adult female. Length 1 mm. Wing 1*05 mm. x "45 ram. 



Colour yellow : thorax tinged with brown, body and legs dusted 

 with white meal. Eyes reniform, almost divided. Upper half cherry- 

 red lower half maroon. There is a large rectangular brown patch on 

 last segment of abdomen : within it and at the upper end is the vasi- 

 form orifice. Vasiform orifice oval. Operculum small, extending only 

 to centre of orifice. Lingula long, cylindrical, extending a short dis- 

 tance beyond vasiform orifice. Forewing patched with bluish grey. 

 These patches lie in the form of three bars which run across the wing 

 being more or less interrupted at median vein. A longitudinal bar con- 

 nects all the transverse patches. This bar is situated below the median 

 vein but is prolonged above the vein to apical margin of wing. Apex 

 of hind wing tinged with grey. Antenna? yellow; Formula 3, 2, (5, 6, 7,) 

 1,4. 1st joint short, stout: 2nd joint subpyriform, almost globular : 

 3rd joint thin, cylindrical, two-and-a-half times the length of joint two : 

 4th joint extremely short, half the length of joint two : joints 5, 6, and 

 7 one-and-a-half times the length of joint four. There is a dark line on 

 each side of the under-surface of the second and third segments of the 

 abdomen. The undei'-surface of the last segment of the abdomen with a 

 patch of grey. 



Adult male. Size *95 mm. Wing '9 mm. x "33 mm. 



Colour yellow : dorsally segments of abdomen and thorax tinged 

 with grey. Last segment of abdomen and gentalia uniform grey. Rest 

 as in female. 



I first found this Aleurodid on the leaves of a seedling banyan 

 (Ficus indica) lodged on the trunk of a mango tree in the vicinity of 

 Calcutta. I was only able to obtain some half a dozen pupae at the 

 time. I was much struck by the gelatinous looking secretion of the 

 insect. It is the only Aleurodid which I have obtained which produces 

 such a secretion. It is possibly allied to A. gelatinosus, Ckll., although 

 when the two insects are compared they appear to be very dissimilar. 

 A. gelatinosus is elevated off the surface of the leaf by its lateral 

 fringe, not so in this species. The margin of A. gelatinosus is deeply 

 crenulated, while in this species the crenulations are quite difficult to 

 detect. It differs in colour, A, gelatinosus being black : but the two
