An error has been committed in the " Guide " by referring this 

 insect to Latreille's genus Cerostoma, which appears to be 

 synonymous with Ypsolophus : I have now the pleasure of 

 adopting Mr. Haworth's name, which was given in his Lepi- 

 doptera Britannica, where the genus is characterized : Che- 

 laria has been selected for it, from its curious palpi having 

 some resemblance to the claws of a Lobster or the mandibles 

 of a Chelifer. (See Kirby and Spence's Introd. to Entomol. 

 pi. 5./. 4^.) 



Remarkable as this little Moth is, we know nothing of its 

 economy; the Caterpillar and Pupa do not appear to be de- 

 scribed or figured, and it is simply stated by Linnaeus and 

 Fabricius that the Imago lives in woods. Mr. Donovan, who 

 believed it to be a nondescript, says it was taken in the vicinity 

 of Feversham, Kent ; it is however by no means a rare insect ; 

 I have frequently found it in Norfolk and in the neighbour- 

 hood of London, towards the end of August, generally I think 

 in gardens ; and Mr. Dale meets with it in similar situations 

 in Dorsetshire. 



In dissecting the Moth, I was unable to discover the ante- 

 rior (maxillary) Palpi, mentioned by Mr. Haworth: it must 

 also be observed that the basal joint of the labial palpi is 

 concealed in the mouth, and that the long bundle of hairy 

 scales which clothes the greater part of the 3rd joint, gives 

 the naked and terminal portion the appearance of a 4th joint. 



The Plant is Daphne Laureola (Laurel Mezereon), com- 

 municated by the Rev. Professor Henslow from Hinton near 

 Cambridge.
