﻿A SUCCESSFUL MOTH-TRAP. 231 



Gosport. A few years ago Mr. Larcom had a brood of larvae on the ivy 

 in his garden, in Shaftesbury Road, Gosport. L. minima (alsus). — Ports- 

 down Hill, common, but rather local. 



Ertcinidjb. 

 Nemeobius lucina. — In glades in Stakes Wood, not common. A few 

 years ago Mr. Larcom and myself met this species in a meadow between 

 Stakes and Purbrook, but only once. 



HESPERIIDiE. 



Syrichthus malvce (alveolus). — Purbrook Common, few ; Stakes Wood, 

 and Scratch-face Lane, Stakes, common. 



Nisoniades tages. — Portsdown Hill, few, eastern end, north of Portsdown 

 Hill ; common, in woods and lanes. I have never found it south of the hill. 



Hesperia thaumas (lined). — Most abundant throughout the district in 

 and near woods. H. sylvanus.— Generally distributed, and generally more 

 abundant throughout the district than H. thaumas. H. comma. — Used to 

 oocur on Portsdown Hill, near Paulsgrove. The spot where it was most 

 abundant was taken into the chalk-pit about ten years ago, and the insect 

 has now disappeared. Mr. Larcom and myself paid several visits to the 

 spot during the past six years in hopes of finding this species, but were 

 always unsuccessful. 



The Heterocera of this district I estimate at about 800 

 species. A list of these I hope to publish at no distant date ; 

 that is to say, as soon as I can obtain definite information 

 respecting doubtful species, rarities, and other species not on 

 my list.

A SUCCESSFUL MOTH-TEAP. 



By W. M. Christy, F.E.S. 



During this and the last three seasons I have used a moth- 

 trap which I had constructed from my own designs, and as it 

 has proved so useful in obtaining me many specimens of Lepido- 

 ptera, I thought some account of it, and the work it has done, 

 would interest the readers of the ' Entomologist.' The accom- 

 panying diagram of the trap, I think, explains itself; I will, 

 however, venture to describe the details, a, b. c, d, is a box, 

 having a partition, e, f, to separate the lamp-chamber from the 

 moth-chamber. In the centre of this partition is a glass window, 

 G, through which the lamp shines. The box is open at b, c, and 

 there is a door in the back, a, d, through which the lamp may be 

 taken out for cleaning and trimming. There is a chimney, h, 

 coming out through the top to carry off the heat and smoke of 

 the lamp ; around the lower part of the lamp-chamber there are 

 ventilation holes to admit air to the lamp and prevent the box 

 becoming very hot.
