213 I Septenilier, 



Turner exhibited a fine series of Pempelia palumbella, Hb., from Oxsliott, also a few 

 Thera variata, Schiff., one being almost unicolorous, and T. firmata, Hb., &c. Mr. 

 Dennis brought a box of Thecla hetulce, bred at the end of June, one having the 

 orange band somewhat smaller than usual. Mr. R. Adkin exhibited specimens of 

 Smerinthus populi, L., from Lewisham, the New Forest, and Sutherlandshire, 

 for comparison, three of those shown being of that very light brownish form that 

 occasionally occurs, one from each of the localities named ; also a few Smerinthus 

 ocellatus, L., bred from larvae found at Lewisham. Mr. Barrett exhibited the 

 larvae referred to by him at the last meeting, and made some comments thereon. 

 These larvae, if not actually still alive, were in a state of very fresh preservation, and 

 Mr. Weir said he thought there was hardly any doubt about their having been 

 stored by one of the Mason wasps, as food for its young. Mr. H. Williams exhi- 

 bited five pupae of Leucophasia sinapis, L., for the purpose of showing the gradual 

 development of the perfect insect, one of which emerged during the course of the 

 evening. The average dates were: ova laid May 26th, hatched June 6th, the first 

 pupating on July 9th. Mr. Step exhibited the following species of galls from 

 Epsom, viz. : Andrlciis fecundatrix, Htg., Neuroterus lenticularis, Olivier, Andricus 

 ostreus, Cynips Kollari, Rhodites neriwsus, Curt., R. rosce, Htg., and R. eglanterice, 

 Htg. 



August 10th, 1893. — The President in the Chair. 



Mr Frohawk exhibited specimens of Macroglossa bombyliformis, together with 

 a species of humble-bee, which it mimics, captured in company over rhododendrons 

 in the New Forest, on 21st May last. Mr. Jenner Weir exhibited some cases which 

 had been found under a sycamore by a neighbour of his, Mr. Tolhurst, at Becken- 

 ham. He said that attention had been called to these cases by seeing them hopping 

 on a gravel walk, a power which they retained for some days. The cases were 

 circular discs, about 13 mm. in diameter, and had been made from the upper cuticle 

 of the sycamore leaf, forming one side, and silk the other. Upon examining the 

 leaves of the tree, the round spots from which the cases were partly formed were 

 plainly visible, and also the large blotch, from which the larva had eaten the 

 parenchyma. It was at first thought that they might belong to a Tischeria, but 

 they have since been identified by Mr. McLachlan as being the work of a saw-fly, 

 Phyllotoma aceris, Kaltenbach, a species already known in this country ; a some- 

 what detailed life-history was given by C. Healy in the Ent. Mo. Mag., iv, pp. 

 105 — 107 (1867), but the most complete is that by Ritzema Bos, in the Tijdschrift 

 voor Entomologie, vol. xxv, pp. 7 — 16, pi. iii. The President also exhibited nearly 

 adult larvae of Hemerophila abruptaria, and drew attention to the fact that two 

 pairs of prolegs were, as usual in Geometers, fully developed, and that there were 

 also two other imperfect pairs in front of these. He considered these very imperfect 

 prolegs to be vestigial. Mr. Robt. Adkin exhibited a specimen of Sesia cynipi- 

 formis, bred from pupae found in Sussex, and called attention to the usual red 

 colouring of the bar, and a portion of the costal streak of the left fore-wing being 

 replaced by yellow ; he also exhibited a series of Spilosoma lubrieipeda, bred from 

 Yorkshire larvae, in some of which the spots showed a tendency to become elongated. 

 Mr. C. Oldham exhibited series of Sphinx ligustri, Apamea ophiogramma, CaJymnia 

 affinis, and other species, chiefly taken at Woodford. — H. Williams, Hon. Secretary.
