paid to Botany. He had talked the matter over with Mr. 

 Step, who had been kind enougli to say that during the season 

 he would exhibit and make some remarks on the various wild 

 flowers he might meet with. He also suggested that when 

 out on Entomological expeditions, members should gather 

 what shells they met with and hand them to those who studied 

 this branch of Natural History, for naming and exhibition ; 

 he also thought it desirable that Ornithological exhibits 

 should be more frequently made ; the Arachnida too offered 

 a good opening for members to distinguish themselves, as the 

 group was but little worked. Mr. Carrington concluded by 

 expressing the hope that country members would forward 

 specimens for exhibition, also records of the occurrence in 

 their district of rare and local species of all orders, and notes 

 and observations relating to the subjects studied by the 

 Society. 



FEBRUARY 2^th, 1890. 



J. T. Carrington, Esq., F.L.S., President, in the Chair. 



Messrs. W. Smith, W. Bloomfield, and G. A. Farini were 

 elected members. 



Mr. T. R. Billups, on behalf of Mr. T. D. A. Cockerell, 

 exhibited Galls collected at West Cliff, Colorado, U.S.A., and 

 read the following note by Mr. Cockerell : — 



" The galls now exhibited were all collected on a strip of 

 land about a quarter of a mile long, close to West Cliff. The 

 rose galls are of three species. The smooth round galls are 

 those of Rhodites ignata, Osten-Sacken, from which, however, 

 an abundance of a parasitic Cynipid, Periclustus pirata, 

 Osten-Sacken, will be bred. The irregularly-shaped rough 

 galls belong to Rhodites fusiformans, new species. The little 

 blister-like galls on the leaves will produce Rhodites roscefolicE, 

 Cockerell. Of the willow galls, the reddish fusiform ones 

 produce Cecidoinyia salicis-siliqiia, Walsh. The bud-galls are 

 those of Cecidomyia salicis-strobiloides^ Osten-Sacken. From 

 these galls many Chalcids, including some new species, v/ill 

 be reared, in addition to the gall-makers." 



Mr. Cockerell also forwarded lepidopterous ova found at 

 the same place as the galls, which would produce larvae of 

 Clisiocanipa californica, Packard, a species allied to C. neiistria 

 of England, The larvae might be fed on Salix, Populus, or 

 Ribes aureum. The eggs sent were found on willow.^ 



^ These eggs produced larvae, which commenced to feed on sallow, but most 

 died at the first moult, and the rest soon afterwards. The food was evidently 

 unsuitable.— H.W.B.
