in Trinidad, is described and illustrated. Two wire mosquito nets 

 were used in the form of panniers on a mule, being wide enough to 

 sweep two rows of cane planted five feet apart, while the animal 

 walks between the rows. Each net is hinged behind and supported 

 in front by a stout cord or wire attached to the front supporting bar. 

 This is loose in its bearings, and by rotating it. the front of the net 

 can be raised or lowered by the person in the saddle, as the height of the 

 canes changes. The panniers can be rapidly removed by taking out 

 the stop on the rear bar, and unhooking the front supporting cord. 

 The nets are open in front and may be smeared inside with some 

 stickv substance. The advantage of using net is that it allows air 

 to pass through and does not create a back-draught. The framework 

 of nets and saddle is constructed of Hght wooden bars, while the main 

 supporting bars, rear and front, are of one inch iron tubiog. Provided 

 that the nets are not too close to the ground no difficulty is found in 

 taking them over rough ground., open field-drains, or even small gulhes. 



BrxTOX (P. A.). A Liparid Moth {Ocnerogyia amanda, Staud.) 

 destructive to Figs in Mesopotamia. — Ball. Entom. Res., London, 

 xi, no. 2, September 1920, pp. 181-186, 1 fig. 



Figs, though apparently not a major crop, are widely grown in 

 Mesopotamia, and are severely damaged by the larvae of a Liparid 

 moth. Ocnerogyia amanda. Staui. the leaves being sometimes com- 

 pletely devoured and the fruit shrivelling and dropping before it i? 

 ripe. Its eggs are found in patches of from 20 to 100 on the lower 

 parts of the trunks, and more rarely on the underside of the lower 

 leaves or on rubbish on the ground. The larvae feed at night, shel- 

 tering among dead leaves or soil beneath the fig trees, or in mud walls, 

 etc. Pupation occurs in cracks in soil or mud walls. The gene- 

 rations are continuous throughout August and September, all stages 

 being found together at this time. This is unusual among Mesopo- 

 tamian Lepidoptera, which generally aestivate throughout the 

 summer. 



The pest should be fairly easy to keep in check. Arab growers 

 bum the dead leaves and other rubbish ia heaps beneath the trees. 

 This destroys all stages of the insect as well as its hiding-places. 

 Collections of larvae and eggs from beneath the leaves might be made 

 shortly after dawn. 



As only the male of 0. amanda has been previously described, a 

 re-description by Sir George Hampson is appended.

A detailed study is given of the anatomy of the larvae of HeliotJiis

 with those of Protoparce (PhJegethontius) sexta, H. {Chloridea) pTiloxi- 

 phaga, and a number of other Lepidopterous larvae of various genera.
