The President exhibited spi-citneiis of Sfi/lops taken bv himself froTii Andrena 

 atriceps recentlj captured at Hampstead, and remarked on tlioir habits and peculi- 

 arities. Mr. P. Enoch, who had visited the locality at an earlier hour (between 9 

 and 10 a.m.), had taken 17 males, one on the wing. He remarked on the differences 

 presented bj the females of S. Spencii, which infests Andrena atriceps, and S. 

 T'lwailexi, 'pavnsit\c on A. convexkiscula ; and said it was very desirable that the 

 StylopidcB should be carefully examined with respect to the species of bees upon 

 which they were found. One individual of A. atriceps produced a male Stylops, 

 and in the same bee were four female pupae. 



Mr. Smith concurred in the President's remarks as to the desirability of a more 

 extended study of our native StylopidcB, and thought that instead of the few species 

 now recorded, we probably possessed nearer a dozen. 



Mr. C. O. Waterhouse exhibited a species of Chelifer (or allied genus) found 

 under the following circumstances. Being desirous of examining certain structures 

 in a large species of Passalus from Rio Janeiro, he took out the abdomen of the 

 beetle, and the Chelifers were found between it and the elytra. He also exhibited 

 the drawing of the base of the abdomen of a species of AscalaphidcB from W. 

 Australia, remarkable for having, in this position, a large bifid hump, each division 

 furnished with a crest of hairs : the insect was considered to be the $ of Suphalasca 

 magna, McLach. 



Mr. McLaclilan said that Mr. Waterhouse's determination of the species was 

 probably correct ; he believed that a second example existed in Hagen's collection, 

 received by him from Schneider under the MS. name of Azesia camel lis : the only 

 analogous form was Acynonotus incusifer. 



Mr. "Wormald exhibited a box of Neitroptera, &c., collected in Japan by i\Ir. 

 H. Pryer. There were several beautiful species of I'aiwrpa, and a new genus allied 

 thereto. Also a very remarkable Trichopterous insect of the genus Perissoneura, of 

 large size, black, with a large white spot in each wing, deceptively like some species 

 of butterflieo. 



Mr. Miiller communicated a note respecting a recent exhibition, by Mr. Colo, 

 of ash-leaves deformed by a Cecidomyia ; he said it was C. botularia, Winnertz, 

 of which he liad published an account in the 'Gardener's Chronicle' for 1870, 

 p. 1731. 



Mr. McLachlan read an extract from the Kev. A. E. Eaton's first report as 

 Naturalist to the Transit of Venus Expedition to Kerguelcn's Islatid, published in 

 the Proc. Koyal Society. [This extract is reprinted in exteiiso in the present number, 

 ante p. 1]. A discussion ensued as to the manner in which the fact of most of the 

 insects being apterous (or nearly so), might be accounted for. Mr. McLachlan 

 alluded to the idea that the constant prevalence of high winds rendered a large 

 spread of wing useless ; Mr. Jenner Weir stated that another hypothesis had been 

 suggested, viz., tliat as all the endemic flowering plants were apetalous, and appa- 

 rently self-fertilising, the presence of winged insects was not necessary. 



Prof. West wood communicated a paper on short-tongucd bees of the genus 

 Nomia, and another on species of Rulelidce from Eastern Asia and the islands of 

 the liastern Archipelago.
