as many different hosts, the first victim being the larva of Smerinthus 

 ocellatus, L., from which Mr. Winkley reared probably the largest 

 species of ichneumon in the British list — a fine male Tragus Informs, 

 Fab. ; while the pupae of Pieris brassicce, L., produced large numbers 

 of the lovely little Chalcid, Eulophus pecitntcor?iis, Linn., and the 

 larvae of Geometra papilionaria, L., numbers of both sexes of the 

 gregarious Bracon, Apanteles rubripes, L. 



Mr. Herbert Williams sent me five distinct species of parasites, 

 from two hosts only, the first being the larvae of Thecla betulce, 

 L., from which were bred a male and female of Canpoplex in- 

 signitus, Foerst ; the larvae oi Euchelia Jacobcpce, L., being responsible 

 for two species of Ichneumonidae and two of Diptera, the two former 

 being true Bracons, — the first a solitary parasite, Apanteles sericeus, 

 Nees ; the second the rarer Microgaster globatus, Nees, which also 

 appears to be solitary. The Diptera were both sexes of Musca cor- 

 vina, F., and Exorista vulgaris, Fin. 



Mr. Young, of Rotherham, reared both sexes oi Zele testaceator. 

 Cur., from the larvae of Xanthia citrago, L. This parasite is ex- 

 tremely scarce, and so far as I know has only once before been 

 reared in this country. Mr. Adkin bred two males and one female 

 in 1887 from the larvae of Eupithecia coronaia, Hb. 



Life-history of Cicindela campestris, the Common 

 Tiger Beetle. 



By Fred Enock, F.L.S., F.E.S. Read March 26fh, 1896. 



The common Tiger Beetle is so common an insect that most 

 collectors are satisfied to possess a series with which to start the 

 heading of their collection of British Coleoptera, which nine times 

 out of ten is merely a collection of pinned specimens, the chief and 

 growing interest being in the number of drawers filled, not in filling 

 our minds with stores of interesting facts in the life-history and 

 economy of these creatures. 



By this over-collecting of specimens, to the exclusion of facts, the 

 entomologist loses his greatest privilege. It is most gratifying to 

 know that the members of the South London Entomological and 

 Natural History Society are doing good work among the Lepidoptera, 

 but the field for work among the other orders is still waiting for 

 earnest workers. The year 1897 will be a memorable one for all 

 kinds of good works. Why should not entomologists put their 

 shoulders to the wheel, and commence working out life -histories of 

 insects wliich will be handed down in company with all other 

 wonders of the year ?
