 some future time in gratitude for your services, mention you honourably in some 

 great monograph or other. 



To give an idea of the returns to be anticipated from an evening's work, I may 

 remark that it is by no means unusual during a favourable evening towards the end 

 of May, upon a heath or moor (as in the hollows at Shirley), to meet with larvae of 

 the following in greater or less abundance : Agrotis agathina and porphyrea, 

 NoctvM neglecta and Dahlii, A.myrtilli, P. hippocastanaria, A. strigillaria, F. atoma- 

 ria, and helgia/ria, Eup. minutata and nanata, &c., besides the heterogeneous pot 

 pov/rri before mentioned. 



On reaching home we should lose no time in looking over our sweepings, and 

 this is the modus operandi. — Unfasten the bag, shake out a handful or so into a 

 large white meat-dish, and having tied up the bag again and distributed the sweep- 

 ings over the surface of the dish, proceed to examine ; put the Lepidopterous larvae 

 into glass-topped jam pots, in which fresh sprigs of the food-plant have already been 

 placed ; the beetles into a laurel bottle ticketed " For E. C. Rye ;" the bugs into 

 another " For John Scott;" pin the Hymenoptera "For F. Smith ;" and immerse the 

 spiders in a bottle of proof- spirit "For the Rev. 0. P. Cambridge :" — repeat the process 

 untU the sweepings are exhausted, placing them after each examination into what 

 is known as a " sixpenny pan," which tie over with muslin : for days after Coleo- 

 phorcB will (and PsychidcB would too, if present) come up and attach themselves to 

 the muslin, where they may be instantly detected. Note. — This is the way I 

 should set about obtaining the cases of Psyche nigricans and opacella, as well as 

 other low-feeding case-bearers. 



With three lines of advice to the larva-hunter, I close this chapter on collecting : 



1. Lose no time in making out the species to which your captures belong. 



2. Do not think that, because you find a larva in abundance, it necessarily 

 pertains to a common species ; or the converse. 



3. Do not expect to breed one tythe of the larvae you obtain by beating and 

 sweeping and you will not be disappointed.

 F.L.S., in the chair.

 Calthorpc Street, were elected Members, and R. Lyddeker, Esq., of Harpenden 

 Lodge, St. Albans, was elected a Subcriber. 



The President read a paper entitled " Notes on generic names having the same 

 sound," in which he strongly condemned the practice (adopted by some Conti- 

 nental writers) of changing generic names because they happened to have nearly 

 the same sound, although placed in distinct orders. In the discussion that ensued, 

 the President's views on this matter were generally acquiesced in. 



Mr. McLachlan read a paper entitled " Trichoptera Britannica ; a monograph 

 of the British species of Caddis-flies," in which were described 124 species, belong- 

 ing to 43 genera. 



Mr. Wood exhibited a variety o^ Apatura iris, from Kent. 



Professor Westwood mentioned that, with respect to the specimens of Ixodes 

 exhibited at the last meeting, he had discovered that De Geer had already noticed 

 the remarkable position of the male when in copv.U ; he remarked also that he had
