January or February of each year. After the insects have deserted 

 the galls, the latter too disappear leaving holes all over the leaf, 



" I have seen the leaves of larger trees, 8 to 10 feet high, so 

 attacked, but the damage is but slight. My observations extend 

 only over the Shahapur taluka of the South Thana Forest Division." 



2.— DESCRIPTION OF A NEW SPECIES OF ALEURODES 

 DESTRUCTIVE TO BETEL. 



By G. B. Buckton, F.R.S,, etc. 

 Aleurodes nubilans, n. sp. 



Plate V. Jigs. J-g. 



Legs long and hairy with dimerous tarsi. Antennae rather long 

 and with seven (?) joints in the $, which is a larger insect than the 

 $ . Wings four, rounded at the apices, and fringed with minute 

 hairs. A single unforked central nervure, not continued to the 

 margin. Membrane smoky in patches, with a darker blurred spot. 

 The S smaller with a large thorax, taper abdomen, and furcate at 

 the apex and with hinder legs longest. 



The larvae crowd the undersides of the leaves of the betel in the 

 form of small scales very difficult to detach. They appear like scales 

 of some Coccidse, but these showed no distinct organs such as anten- 

 nae, legs, or eyes. Their outer surfaces were more or less spined, and 

 some larvae were tufted with wooly matter, each thread being 

 formed of a continuous spiracle. 



This new Aleurodid was received on betel leaves from the 

 Manager, Court of Ward's Estates, Backergunge, who reported that 

 it was doing considerable damage to the plants.
