NOTES AND OBSERVATIONS. 67 



morning found the insect on the window-curtains, it evidently having 

 revived. On the following Wednesday or Thursday I handed it to 

 my brother-in-law, Mr. Bertram Earp, who is a very keen entomolo- 

 gist, and w^ho identified it as Chcerocampa nerii. The specimen is 

 now in his collection." — Egbert Adkin ; Lewisham, January, 1911. 



Amphidasys betularia ab. doubledayaria in Essex. — In the 

 ' Entomologist ' for last year, at p. 204, the Eev. W. Claxton records 

 the occurrence of a female example of this aberration at Navestock, 

 and i-emarks that it "is perhaps a record for Essex" ; so it may be 

 interesting to him and others to learn that in this corner of the 

 county the black variety is by no means uncommon, indeed, it is now 

 as frequent as the type. I came to this neighbourhood in 1886, and 

 for a few years after the larvae, usually obtained every year, of this 

 insect produced typical specimens, although many of them were often 

 very dark— almost intermediate between the type and doubledayaria 

 — and they have become darker and darker every year, and at the 

 present time nearly half the moths reared from the wild larvae I 

 obtain emerge as doubledayaria. A few years ago one of my children 

 found a large female doubledayaria sitting on my front door-step, 

 and from her I obtained a quantity of ova. When they hatched, the 

 young larvae were sleeved upon an ash-tree in my garden, and from 

 these the following year I bred over one hundred moths, more than 

 two-thirds of which were the black variety. The wild larvae seem to 

 have no particular choice of food, for I have beaten them from every 

 kind of tree and bush, and on several occasions from mugwort, 

 when' hunting for larvae of Eupithecia succenturiata at night. —

Corrections in Names op Three Species of Phytophaga. — The 

 late Mr. Jacoby in Trans. Ent. Soc. 1897, p. 260, described a Hermao- 

 pliaga as smithi from the West Indies. This name has been pre- 

 viously used in the ' Biologia,' Supp. p. 262, for a Mexican form. In 

 his second collection Mr. Jacoby had altered the name-label of the 

 West Indian form to insularis, Jac. In P. Z. Soc. 1903, p. 284, he 

 describes DorypJiora ceneofasciata from Columbia, on page 291 ; he 

 inadvertently uses the same name for a Peruvian form. In his copy 

 of the published paper (in my library) the latter name is changed by 

 him to chalybeofasciata ; on page 287 he uses the name DorypJiora 

 sanguiniyennis for a form from Brazil ; he had previously used this 

 name (Entom. 1895, p. 189) for a form from Venezuela ; the Brazilian 

 species should be altered to sanguipennis. — C. Bowditch ; Brook- 

 line, Mass., U.S.A. 



Abnormal Emergence of Coremia designata. — At the beginning 

 of last September I received a batch of ova of this species from the 

 South of Ireland. They hatched on the 14th of the month, and fed 

 up well on cabbage. The breeding-cage was kept in an open shed 

 out of doors, facing the north-east. On December 23rd I was sur- 

 prised to find four of the moths had emerged, on the 25th another 

 appeared, on 31st another, and another on January 10th. x\fter this 

 I brought the breeding-cage indoors. I cannot understand why
