be with North France. Personally, it seems to me much more 

 probable that hybernated imagines from Cornwall should renew the 

 atalanta population of England than that they should come all the 

 way from the w^armer parts of Europe ; but, as already pointed out, 

 neither hypothesis is necessary, unless the possible hybernation in 

 states otlier than the imago is disproved. Tliere is one other form 

 of evidence possible. Has atalanta been seen or recorded in mid- 

 Channel at all frequently ? I have seen on the Riviera, on two 

 consecutive days, huge fiiglits of carclui come up from the sea — so 

 many, indeed, that they passed for perhaps a quarter of an hour ; 

 but^I do not know whether anything of the kind has been observed 

 with atalanta. — J. C. Warburg. 



Second Brood of Cerura furcula. — On June 22nd I found 

 four small larvag of this species, of which two duly pupated. I put 

 the pup£e in a cage with others due to emerge next year. On July 

 29th I casually looked at the cage, when I found that the imago had 

 emerged from each of the above-mentioned pupae. One had evidently 

 been out several days, as it had knocked itself about, so that it had 

 become useless as a specimen ; the other was in better condition. I 

 see that Barrett gives one instance of this species having a second 

 emergence in this country. In the present abnormally hot summer 

 it seems probable that several species, ordinarily single-brooded, may 

 produce a second brood, and I think lepidopterists should place on 

 record instances which come to their notice. — C. G. Nurse (Lt.-CoL);

Note on Agrion arjiatum, Charp. — Perhaps a note supple- 

 mentary to Mr. W. J. Lucas's remarks on Agrion armatum in the 

 current number of the ' Entomologist ' may not be out of place. 

 When Mr. Lucas writes, " The specimen was of as bright a blue as 

 that of Agrion intella,'" &c., it must not of course be understood that 

 the entire body was blue. The pale marks, as shown in the plate, 

 on the frontal and posterior segment only were of the bright blue 

 colour, and the same remark applies to the brilliant green of the 

 prevailing form in the Broads. Erom my experience the blue-marked 

 form is rare in the Norfolk Broads, for I only captured one, and I do 

 not think I saw another among the large number I saw on May 28th 

 last year, nor among the fewer specimens seen on the several previous 

 days. On tlie other hand, descriptions of tlie species seem to denote 

 the blue-marked as the prevailing form on the Continent. I don't 

 know from where Mr. Lucas got the notion that I took " about a 

 dozen on May 28th," for on that day I took a considerably larger 

 number than that, but not nearly so many as I saw! — Geo. T.

Geographical Distribution of Macaria liturata var. nigro- 

 pulvata. — As the season has come round again for larvae of M. litur- 

 ata, it would be interesting if collectors could add to the localities for 

 this interesting and well-defined variety, as well as publish their 

 results in the ' Entomologist ' when the moths emerge next June. 

 September is perhaps the best month for the larvae, but many are to be 

 had in the first half of October. I have never beaten the caterpillar
