cannibalistic they got. For experiment's sake I placed a nearly full-fed 
N. dictmides^ a half-grown larva of the same species, two N. cd^nelvia^ 
and two N. dromedarius^ about half-grown, into a little cage ; the smaller 
N, dictceoides 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 Calocanipa solidaginis deposits about the end of September, 
remaining in the egg-state throughout the winter, until 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 Sligo. — 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 larvae could 
be obtained by beating the hawthorn. — P. H. Russ, Sligo. 2 5 //it, 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 pupae which lie over the winter and emerge 
in May. I collect the larvae of C. silaceata in August, and I find 
them on willow herb {^Epilobium angustifolium). I have also found 
the larvae feeding on E, mo 7 ita 7 ium. The insect is on the wing in June, anJ 
there is only one brood in the season in this locality. — John Finlay, 
Meldon Park, Morpeth. September 'T^oth^ 1891. [In the Isle of Wight, 
August, 1889, I took several C. silaceata, all small and very dark, 
decidedly a second brood. — Ed.] 
Nonagria concolor in Suffolk. — Whilst collecting m Suffolk last 
July I captured a single specimen of Nonagria co?icolor. The species 
has since been identified by Mr. Tutt. — A. W. Mera, 79, Capel Road, 
Forest Gate. 
Sugaring for Gonophora derasa and Thyatira batis. — Apro- 
pos of a remark in Mr. Simes’ article {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 Nocture, among others I may mention 
Miana strigilis and M. furuncula, Cerigo cytherea (abundant), 
Xylophasia hepatica (very abundant), Agrotis puta, Aplecta nebulosa, 
Noctua trianguhim, Luperhia cespitis etc. Geometry may also be 
taken more freely thus than at the sugared trees j I have repeatedly 
met with Larentia olivata, besides Gnophos obscii?ata, Acidalia 
scutulata and many commoner species. Those sprays on which the 
young berries are forming will be found to hold the sugar best. — R. M. 
Prideaux, 9, Vyvyan Terrace, Clifton, Bristol. September 25//?, 1891.
