species agree in producing an apparently similar substance, and the 

 distinctive feature, the indentures on the cephalo-lateral and caudal 

 margins with the pencils of wax issuing therefrom, are common to both. 

 I have, within the last two years, frequently come across this species ; at 

 first only on banyan (Ficus indica) seedlings, where I searched for it ; 

 but later on also on pepul (Ficus religiosa) seedlings as well. I find 

 that especially after the rainy season (about October) the insect simply 

 swarms on the young banyan and pepul plants, which spring up during 

 the rains on buildings, rubbish heaps and the like. In the case of the 

 pepul seedlings it is frequently associated with A. quaintancei. One 

 peculiarity, however, is that I have only found this species on young 

 plants, and when the two species are both present on the same plant 

 this aleurodid is always to be found on the lower and older leaves. I 

 have failed so far to find the insect on banyan or pepul trees, though I 

 have frequently searched for it. So far, I have only obtained this spe- 

 cies from two localities ; at Turkaulia, Champaran district, Behar, and 

 in and around Calcutta. The insect is heavily parasited by a minute 

 yellow chalcid. When parasited the dorsum becomes very convex and 

 when the parasite pupates it can be seen quite easily within the body. 

 Although it is to be often found associated with A. quaintancei the chal- 

 cid parasiting A. quaintancei never to my knowledge attacks this species. 

 It is a pity that the insect should suffer so severely from this parasite, 

 as it undoubtedly does some indirect good by killing off the enormous 

 numbers of pepul and banyan plants which take root on old buildings 

 and the like, and which would otherwise in many cases grow up and do 

 future injury. The aleurodid is usually present in large numbers, sev- 

 eral hundred being frequently attached to a single leaf, in the greater 

 number of cases eventually killing off the plant. Most of my material 

 has been obtained from the Museum terrace. I may note that I have 

 failed so far to obtain specimens of the 2nd stage ; the stages marked 

 2nd and 3rd being probably the 3rd and 4th. I have much pleasure in 

 naming this species after Major A. Alcock, F.R.S., CLE., Superin- 

 tendent, Indian Museum, to whom I am much indebted for encourage- 

 ment in my entomological studies. 



4. Aleurodes quaintancei n. sp. Plate V, Figs. 10-14. 



Egg. Size -18 mm. x *09 mm. 



Cream coloured when recently laid, changing later to light brown. 

 Peduncle about one-third length of egg. The eggs are usually laid 

 four or five abreast in a curved line. 



I take this opportunity of naming this species after Mr. A. L. 

 Quaintance, to whom I am indebted for much valuable assistance in mj 

 study of this family.
