of a larva enclosing a largo Ichneumon grub. We have also taken Lithosia 

 deplana, Esp., in the perfect state at rest on tree trunks, and as the unhibernated 

 larva, near Milford. 



Finally, I may mention the capture of Xylina seniibrunnea. Haw., at rest 

 on a telegraph pole at Griiildford, and the rearing of several Halias hicoloranu, 

 Fuess., from larva; taken on oak in company with imagines of H. x>rasinana, L., 

 and Sarothripus undulanus, Hb., at Woking. 



The species marked * are not recorded in Mr. H. Goss's list for Surrey in 

 the Victoria History, pp. 110 — 136 (1902), biit Tholomiges Uir/osalis, Lojjhoptenjx 

 carmelita, and Cymatophora octogesiina are referred to as occurring in the 

 county in the more recent publications I have seen. — H. G. Champion,

Microdon eggeri, Mile, in nests of Formica sanguinea, Latr., in the Liixem- 

 burg. — Dr. Sharp, when recording this interesting addition to the British list 

 fEnt. Mo. Mag., vol. xlvi, p. 274), mentions that Wasmann has found the larvae 

 with F. sanguinea in the Luxembui-g, but is unable to remember in what publica- 

 tion it is mentioned. The reference may be found in Wasmann's " Zur Kentniss 

 der Ameisen u. Ameisengaste von Luxemburg " (Ai-chiv. trimestr. d. I'lnstit. 

 Eoyal. Grand-Dukal. Luxemburg, 1909, T. IV, Fascic. Ill, p. 50). Wasmann 

 states that he found the ripe pupse of these flies under the bark and in the " runs " 

 of stvunps inhabited by sanguinea towards the end of April and in May. From 

 the middle to the end of May the imagines hatched and flew away to pair. The 

 females returned to lay their eggs in the early part of June. He found the young 

 larvte in the nests from the middle to the end of June. In the Journal of the 

 New York Ent. Soc. (xvi, 4, 1908, pp. 202 — 213) a very interesting and valuable 

 paper by Wheeler on " Microdon " is to be found. In the Ent. Record, 1909, 

 pp. 18 and 19, I wrote a short account of the habits of Microdon mutabilis, L., 

 and gave a photograph of the larva, pupa, and imago. Microdon eggeri may live 

 with other ants besides F. sanguinea, and it is possible that this species occvu'S 

 at Ramioch, as I discovered it both at Aviemore and Nethy Bri dge. — Horace 

 DoNiSTHORPE, 58, Kensington Mansions, S.W. : January, 1911. 



Ancylus-like Mycetophilid larvse in Epping Forest. — With reference to the 

 Ancylus-like Mycetophilid larvae described by the Rev. E. N. Bloomfield (Ent^ 

 Mo. Mag., March, 1910), I should like to record the finding of similar larva 

 under a fallen beech branch in Epping Forest (Ching-ford) on November 5th, 

 1910. Their diameters varied from 1 — 4 mm. Unfortunately I did not breed 

 them. — Keppel H. Baknard, Etwas, Farnham, Surrey : December 17th, 1910. 



Halesus guttatipennis in Scotland in October. — Refen'ing to Mr. K. J. 

 Morton's note (anted, p. 19) recording the occurrence of this Trichopteron on 

 the Tyne at Ormiston on the 4th of this month, I find I have a specimen which 

 I captured some thirteen miles further down the same river, at East Linton, on 

 October 15th, When wo mot with the species at Ormiston I mentioned to
