Is already known to prey on nearly thirty different species 

 of lepidoptera in this country alone, and no doubt many addi- 

 tional hosts will in time be recorded. I have obtained great 

 numbers in March and April from larvte of Noctua xanthograplia 

 and Trvphcena fimbria, and in June and July I have bred it very 

 commonly from larvae of Miselia oxyacanthce, while in the autumn 

 I have found that the caterijillars of TripJicena prormha suffer 

 greatly from its attacks. In addition, I have reared it from the 

 following hosts : Triphcena orbona, May 30th, 1909, and many 

 other dates ; Brachionycha spldnx, June 8th, 1912 ; Stilbia 

 anoinala, April 28th, 1909 ; Agrotis strigula, April 2nd, 1914 ; 

 Camptogramma bilineata, April 17th, 1912, and April 24th, 1914 ; 

 and Xanthorrhoc montanata, April 21st, 1914. I have also a brood 

 obtained by Cockayne from Mamestra pisi, taken at Limber, 

 North Lines., and in Harwood's collection is a specimen bred 

 from Toxocampa craccce. 



My largest brood (thirty-nine) was obtained from M. oxy- 

 acanthfe, the smallest (seven) from X. montanata. Both sexes 

 are represented in each brood, the females being usually in a 

 proportion of two to one. 



BRITISH ODONATA IN 1910. 

 By W. J. Lucas, B.A., F.E.S. 



Although the latter part of April was warm and bright, it 

 w'as not till the first day of May that I saw a dragonfly, on 

 which date a Pyrrhosoma nymphula, Sulz., was sighted near 

 Beaulieu River in the New Forest. No further member of the 

 Odonata came within my ken till the South London Natural 

 History Society's excursion to Wisley, in Surrey, on May 20th, 

 when two further species were met with — Agrion puella, Linn. 

 (W. J. L.), and Libellula dejwessa, Linn. (H. J. Turner). On 

 June 3rd A. puella, ? , was captured on Effingham Common 

 and Enallagma cyathigerum, Charp, ? , near East Horsley — 

 both in Surrey (W. J. Ij.). Calopteryx virgu, Linn. (L. C. E. 

 Balcomb) and P. nymphula (W. J. L.) were taken, and L. de- 

 yreasa (W. J. L.) was seen in the New Forest on June 11th ; 

 while L. depressa was also seen (W. J. L.) near Netley Heath, 

 in Surrey, on the occasion of the South London Society's 

 excursion to Clandon on June 24th ; but it eluded capture. 



E. cyathigerum was common a few miles from King's Lynn, 

 Norfolk, in May and June (E. A. Atmore) ; while Agrion mer- 

 curiale, Charp., was not uncommon, but extremely locnl, in two
