NOTES ON COLLECTING, ETC. 257 



cannibalistic they got. For experiment's sake I placed a nearly full-fed 

 JSf. dictceoides, a half-grown larva of the same species, two N. cameHna, 

 and two JV. dromedarius, about half-grown, into a little cage ; the smaller 

 N. dictiBoides was gone next day, but the other larvae were never touched, 

 although they were together nearly a week. — Richard Freer. 



Hybernation in egg-state of Calocampa solidaginis and 

 Oporabia filigrammaria. — I do not think it is generally known (at 

 least, I could obtain no reliable information at the time I made the 

 inquiry) that Calocampa solidaginis deposits about the end of September, 

 remaining in the egg-state throughout the winter, imtil about April 

 26th, before hatching, and will take to hawthorn as a substitute for 

 bilberry. I noted that a good many examples were taken last year. 

 I should like to hear if anyone's experience corresponds with mine. 

 Oporabia filigrammaria also has the same habit, only they hatch in 

 March and feed up very sharp, as they are full-fed and out of sight 

 by the middle of May. — J. Harrison, 7, Gawber Road, Barnsley. 



EupiTHECiA dodoneata AT SuGO. — I have no doubt all the 

 specimens captured by me (about a dozen) were taken, at dusk flying 

 along hawthorn hedges ; we have no oak anywhere near here. This 

 agrees with Mr. Atmore's experience, and probably the larv;:e could 

 be obtained by beating the hawthorn. — P. H. Russ, Sligo. Sep. 2$th, 1891. 



SiNGLE-BROODEDNESS OF CiDARiA siLACEATA. — I have bred Cidaria 

 silaceata for the last ten years, and during that time I have only 

 once had two insects emerge at the end of August, and they were much 

 smaller than those from the pupse which lie over the winter and emerge 

 ih May. I collect the larv^ of C. silaceata in August, and I find 

 them on willow herb {Epilobiuin angustifolium). I have also found 

 the larvae feeding on E. montanum. The insect is on the wing in June, an i 

 there is only one brood in the season in this locality. — -John Finlay, 

 Meldon Park, Morpeth. September 30//^, 1891. [In the Isle of Wight, 

 August, 18S9, I took several C. silaceata, all small and very dark, 

 decidedly a second brood. — Ed.] 



Nonagria concolor in Suffolk. — Whilst collecting in Suffolk last 

 July I captured a single specimen of Nonagria concolor. The species 

 has since been identified by ^Ir. Tuit. — A. W. Mera, 79, Capel Road, 

 Forest Gate. 



Sugaring for Gonophora derasa and Thyatira batis. — Apro- 

 pos of a remark in Mr. Simes' article i^Ent. Record, p. 183) that 

 " Thyatira derasa and T. batis were common over bramble, but refused 

 to come to sugar," I should like to suggest to entomologists that they 

 should often try sugaring sprays of bramble blossom, instead of trees, 

 or in bushy localities where there are no trees. I have always taken 

 T. batis and G. derasa more freely by this method than by any other, 

 besides numbers of other NocTU^, among others I may mention 

 Miana strigilis and M. furunciila, Cerigo cyiherea (abundant), 

 Xylophasia hepatica (very abundant), Agrotis puta, Aplecta nebulosa, 

 JSloctua triangulum, Luperina cespitis etc. Geometry may also be 

 taken more freely thus than at the sugared trees; I have repeatedly 

 met with Larcntia olivata, besides Gnophos obicutata, Acidatia 

 sc'itiilata and many commoner species. Those sprays on which t'.;e 

 ycjung berries are forming will be found to hold the sugar best. — R. M. 

 Pkideaux, 9, Vyvyan Terrace, Clifton, Bristol. September 2^th, 1891.
