72 [August, 1S73. 



Mr. Miiller exhibited the case of a species of PsychidcE sent from Calcutta by 

 Mr. Rotliney, formed of the long spines of some tree arranged longitudinally, so that 

 the points were all at the upper end. 



Sir S. S. Saunders exhibited a scries of liring larvas of Hymenopterous insects 

 •which inhabited the stems of brambles received from Albania ; some of the stems 

 were split longitudinally so as to show the cells formed by the parents. They con- 

 sisted of species of Trypoxylon, JRJuqjhit/lossa, Psiliglossa, Odynerus, Osmia, &c. 



Mr. Miiller read notes by Dr. Joly, in which the latter announced that he had 

 discovered the transformations of a new species of Oligoneuria, and sent drawings of 

 the pupa. Mr. McLachlan thought the information furnished was too vague, as no 

 characters were given for the supjjosed new species. 



Mr. WoUaston communicated a paper on the of Cossonidce, being a revision of 

 the group, enumerating 253 species, of which 139 had not hitherto been recorded. 



Mr. R. Trimen communicated notes on variations observed in the neuration of 

 Diurnal Lepidoptera, with reference to some observations recently made by the Rev. 

 R. P. Murray on the same subject. Mr. Trimen thought these variations indicated 

 a tendency to reversion to an ancestral type. 



"tth July, 1873.— H. T. Staintox, Esq., F.R.S., Vice-President, in the Chair. 



Mr. Weir exhibited eight examples of Agrotera nemoralis, recently captured by 

 him in Abbott's Wood, near Lewes. 



Mr. McLachlan exhibited a Dipterous insect belonging to the SyrpJiidce, in 

 which gynandromorphism was presented in a strongly marked form, the genital 

 characters being especially duplex. 



Mr. Miiller exhibited a large leaf of a species of oak brought from Morocco by 

 Mr. Blackmore, the under-side of which had a number of small galls, probably 

 formed by a species of Neuroterus ; and Mr. Blackmore exhibited a large gall from 

 the same species of oak, which, after the escape of the Cynips, had been taken pos- 

 session of by an ant {Cremastogaster scutellaris). 



Mr. Bond exhibited larvaj of the Bruclms from Japan brought before the last 

 meeting. The species was apparently undcsci-ibed, and would be included in the 

 paper on Japanese CurcuUonidce preparing (for the Belgian 'Annales') by M. Roelofs. 



Professor Westwood sent copies of two parts of his forthcoming " Thesaurus 

 Entomologieus Oxoniensis." 



Mr. W. B. Pryer exhibited a selection from his captures of Chinese Lepidoptera, 

 including many interesting species. 



Sir S. S. Saunders read a paper on the ceconomy of certain Hymenopterous in- 

 sects which nidificate in briars, in extension of his exhibition and remarks at the 

 last meeting. He also exhibited a specimen of Rhaphiglossa, in illustration of the 

 manner in which the insect goes to rest ; it had been killed whilst in its natural po- 

 sition in repose, attached by the mandibles to the thorn of a bramble stem, from 

 which it extended at right angles, legs uppermost. Mr. F. Smith reminded the 

 meeting that an analogous habit had been recorded concerning Chelostomajlorlsom- 

 ne, and the individuals obsei-ved were invariably males. 



Mr. Butler read a paper on the species of GaJeodes (a genus of spiders), with 

 descriptions of new forms contained in the collection of the British Museum. 



The next meeting, after the recess, will be held on the 3rd November.
