galls on the Hieracium, and on birch collected in the 

 neighbourhood of Leeds. Mr. Billups placed in the box 

 what he stated was most probably the maker of the galls on 

 the Hieracium {Aulax hieracii, Bouch.), which he had bred 

 in some numbers from the narrow-leaved hawkweed {H. 

 umbellatum), and also some specimens of a hyper-parasite, 

 Decatoma bignttata, Swed. With reference to the galls on 

 the birch, Mr. Billups said he was not certain as to the 

 maker ; but most probably it was a species of Phytoptus, 

 belonging to the Acaridea (or Mites), many of which were 

 gall-makers, and produced very curious plant deformities, ^.^., 

 on the birch, sycamore, lime, maple, alder, blackthorn, etc. 



Mr. R. South exhibited a series of Polyommatus phlceas, 

 L., among which were examples of the vars. schmidtii, Gesh., 

 and eleus, Fahr., and some other interesting aberrations, 

 together with representatives of the species from Europe, 

 Asia, and Africa. 



Mr. R. Adkin exhibited Emmelesia albtilata, Schiff., from 

 pupae received from Shetland in the autumn of 1888, and 

 said that in 1889, four only were bred, in 1890, upwards of 

 twenty, including var. griseata, Stgr., and var. thules, Weir ; 

 he also exhibited pupse of Cedestis gysselinella, Dup. Sta., 

 in drawn-together fir needles, and larvae of Lithocolletis 

 vacciniella^ Scott. Sta., mining underside of leaves of Vaccinium, 

 both from Rannoch. 



Mr. Tugwell exhibited Lare7itia olivata, Bork., from Port- 

 land and other localities, those from Portland being ex- 

 tremely pale as compared with the other examples. Mr 

 Tutt, remarking on pale forms occurring at Portland, 

 instanced Heliophobus hispidus, Hb., and Epunda lichenea 

 Hb. 



Mr. Billups exhibited Lasius Jlavus, De Geer, and the 

 curious little crustacean, PlatyartJirns hoffmanseggii, which 

 occupies the formicarium in company with Lasius flavus. 

 Also the rose beetle [Cetonia aurata, L.), showing the position 

 of the beetle in the cocoon after its change from the larval 

 stage. Mr. Carrington remarked that these cocoons, which 

 had been sent him from a correspondent residing near Ban- 

 bury, were found in old thatch largely composed of clay, in 

 which various plants were growing. 



Mr. Billups then read the following notes: — " In the month 

 of October last, my friend Mr. Williams kindly gave me 

 larvae of Demas coryli, L. and Lophopteryx camelina, L., in- 

 fested with Ichneumons, or perhaps more correctly speaking, 

 with a species of Chalcididse. These parasitical larvae burst
