Cubocephalus nigriventris, Thorns., parasitic on Tetropium. — When I was 

 working for the Tetropium discovered at Market Bosworth by Mr. Bouskell, I dug 

 an Ichneumon out of the cell of the beetle, which I gave to Mr. Morley. He now 

 tells me this is Cubocephalus nigriventris, Th., and has never been bred anywhere 

 before. It has been observed in Norfolk and Devon, and its range extends through- 

 out Northern and Central Europe. The Ichneumon has red legs, as also has Mr. 

 Bouskell's form of Tetropium {T. gabrieli, Weise ?), and is probably rare in this 

 country. — Id. 



Diptera in Dumbartonshire in 1905. — During the past summer I devoted con- 

 siderable time to collecting Diptera, the records of which are very incomplete for the 

 West of Scotland. I met with considerable success, adding many species to our 

 rather meagre list. In the Dolichopodidce I met with about 50 species, including 

 Dolichopus festiviis, D. signatus, D. griseipennis, Hercostomus nigripennis, Hypo- 

 phyllus obscurellus, Gymnopternus celer, Chrysotus cilipes, Argyra confinis (six 

 specimens), Porphyrops micans, Hydrophoras nebulosus, Liancalus virens, Camp- 

 sicnemus loripes, C. scambus, Ectomus alpinus, and Teuchophorus spinigerellus, all 

 of which are new to the local list. In the other families I also turned up a few 

 additions to the list, viz., Follenia vespillo, Cyrtoneura pabulorum, Pogonomyia 

 aljncola, Phorbia muscaria (at sallow bloom), Macrorchis means, M. meditata, 

 Hylomyia Jlavipennis, Chortophila buccata, Mydxa longitarsis? (1 ^ )> Mydasa 

 vespertina, Hydrotn'a militaris, H. similis, Palloptera saltuum, Spilographa zoe^ 

 S. alternata (bred from hips of wild rose), Verrallia aucta, Platypera atra, Urellia 

 stellata, Chilosia Iwnesta, C. bergenstammi, 0. grossa, C. albipila, Conops 4i-fasciata, 

 Helornyza rufa, H. ustulata, Blepharoptera spectabilis ?, Pegomyia latitarsisy 

 P. hcemorrhoum, Merodon equestris (flying among Narcissi at Strathloven), Syrphus 

 guttatus (very common at Spirxa in garden at Strathloven), Chrysogaster splendens, 

 and C. solstitialis (both occurred along with guttatus) , Macquartia afinis, Coelomyia 

 molUssima (very common in several parts of the locality), Sepsis punctum (one 

 specimen), and CarpJwtricha guttularis (two specimens), Xylota sylvarum (one 

 specimen), Platycliirus discimanus (common at sallow on the hills in May), 

 Tephritis miliaris, Balioptera tripuncta (one specimen), B. combinata (common), 

 Em-pis borealis, flying alongside hill streams early in the year, Clinocera fontinalis, 

 common in marshes, along with Parhydra Utoralis. All of these species are new to 

 our published list. I have a large number of specimens still unnamed, and I hope 

 that before the next season opens I may be able to identify all of them. Already I 

 possess lUO species that have not been previously recorded for the Clyde district, 

 and that number will, I have no doubt, be augmented by half, as the result of a 

 season's collecting. — J. R. Malloch, Bonhill, Dumbartonshire : December^ 1905. 



Retarded emergence of Leiocampa dictieoides, Esp. — In November, 1903, I 

 received three pupae of Leiocampa dictxoides from Kent ; these yielded perfect 

 imagines during 1904, on the following dates : June 12th ( ? ), June 13th ( ? ), and 

 July \Uh (^),all three pupae having been kept in the same cage throughout! 

 July 14th seems a remarkably late date for a species that is normally out in May 

 and June, and had the freshly-emerged moth been captured at large then it would 

 have been only natural to suppose that it was an early representative of the second
