the sand-hills, and Choragus Sheppardi from dead wood in hedges; 

 also Sitaris humeralis, found on the wall of his own garden at 

 Hammersmith. 



Mr. F. Smith exhibited some cells apparently formed of clay, 

 made by Geotrupcs stercorarius. 



Mr. VVestwood exhibited specimens of a species of ^y;/i is, which 

 he had described in the Gardener's Chronicle under the name 

 of Pemphigus Lactucce. It had recently destroyed whole beds of 

 lettuces, in various parts of England, by feeding on the roots of 

 the plants. He also exhibited a living Sirex Jiwencus, and noticed 

 its bold attitude when disturbed, likewise the ad;iptation of its 

 limbs for progressive motion in a cylindrical burrow. He also 

 exhibited a piece of wood with several of the burrows formed by 

 this species, a specimen of which just developed was seen'in one 

 of them; in another burrow was a living larva; specimens of 

 Sirex gigas had been produced from the same piece of wood, 

 which was forwarded by Mr. Lamb from Hampshire. He also 

 exhibited specimens of Scleroderma, male, with drawings and 

 dissections, from which and the observations of S. Saunders, Esq., 

 by whom they were captured in Albania, it was proved that the 

 insects, doubtfully described by Mr, Westwood in the second 

 volume of the Entomological Society's Transactions as the males 

 o^ Scleroderma, do not belong to that genus. He likewise showed 

 specimens of the rare Australian Paragia tricolor (from his own 

 collection), described by Mr. Smith at the August meeting, upon 

 the relation of which to the aberrant Vespidcc he made some ob- 

 servations. Also specimens, with drawings and dissections, of 

 two species of a new Australian genus of bees allied to Colletes 

 and Hylceus (from his own collection), one species of which Mr. 

 F. Smith stated was in the collection of the British Museum, from 

 which collection he had described it. Also a larva of one of the 

 larger Harpalidce, which had been destroyed by the larvae of a 

 parasitic Proctotrupes, about thirty of which had burst out of its 

 body in various parts, and had tlien become naked pupae, attached 

 by the extremity of their bodies to their dead victim. 



Mr. Shepherd exhibited a living larva of Anesychia dodecea, 

 from Darenth Wood ; also Crambus aridellus, female, Oncocera 

 lotella, Depressaria 7ianatella, and other rare Lepidoplera, from 

 Deal. 



Mr. Stainton read a paper "On the Laws regulating Entomo- 

 logical Nomenclature," of which the following is an extract : — 



" In nomenclature it is of the greatest importance that entomo- 

 logists be unanimous, for if each one choose to call one insect by
