History Societies. From this Journal we learn that Mr. Haliday 

 has discovered the Gyrinus celox of Schiodte, at Blarney Lake ; 

 Trichopleryx suffocata of Haliday, found in October, the lar%"a and 

 perfect insect in company, under damp fallen leaves or stones, on the 

 bed of a dried brook tributary to the Shounach river; T. mollis of 

 Haliday, on sandy coasts in Ireland, rather rare ; Ptilium angustatum 

 of Erichson, in Ireland, rare ; P. coarctatum of Haliday, taken by 

 himself at Holywood, rare ; and P. clandestinum of Haliday, taken 

 at Holywood by the author, and in England by Mr. Curtis : this latter 

 insect seems to be excessively rare, but Mr. Haliday observes that 

 from its extreme minuteness it may easily escape observation : Corti- 

 caria cylindrica of Mannerheim is also introduced by Mr. Haliday as 

 a novelty, but Mr. Janson subsequently', in the ' Entomologist's 

 Annual,' suggests that Mr. Haliday's insect may be identical with the 

 C. borealis of Wollaston, already noticed. One Hemipterous insect, 

 of the family Lygaeidae, is described as new to Britain, — Dipsocoris 

 alienus of Haliday, the Cryptostemma alienum of Herrich-Schaeffer, 

 found on the banks of rivers in Ireland, throughout the summer, 

 gliding on wet gravel; five Dipterous insects; Clunio marinus, anew 

 genus and species of Chironomidae, found on gravelly sea coasts below 

 high-water mark, walking with its wings half raised and in rapid vi- 

 bration, without taking flight; Dolichopus pra3textatus and Aphrosy- 

 lus celtiber, of the family Dolichopidae ; Geomyza cingulata, of the 

 family Muscidae ; and Canace nasica, of the family Ephydrini. 



In the July number are some interesting remarks on the natatorial 

 structure and habits of two species of Phytobius, found at Holywood 

 on submerged plants of Myriophyllum and Zannichellia. 



The ' Eittomologisfs Avnital.'' 



A second number of the 'Entomologist's Annual' has appeared, 

 giving a useful resume of the entomological captures of the year, with 

 descriptions of species which are new either to Science or to this 

 country. As a matter of course the discoveries among the Tineina 

 greatly preponderate, as is always the case when the attention of the 

 many is once directed into a new or a long.neglected channel. The 

 actual additions to the British list are, in Lepidoptera, Dosithea ebur- 

 nata of Wocke, taken by Mr. Weaver in Wales ; Dosithea circuitaria 

 of Hiibner, taken by Mr. Hunter in London ; Botys decrepitalis of 

 Fischer, taken by Mr. Hodgkinson, but the locality not mentioned ; 

 Chilo obtusellus, taken by Mr. Buxton and Mr. George King at
