Comparative Descriptions of the Larvx of Chesias 

 spartiata and C. obliquaria. — It is a great pleasure to 

 me to acknowledge my numerous obligations to Mr. 

 W. H. Harwood, of Colchester, and in this instance 

 especially for all the trouble he has so kindly and re- 

 peatedly taken to furnish me with larva? of our two 

 British species of Chesias. For three seasons in suc-

 not like to speak before I had made quite sure of the 

 distinctive characters of these larvae, and had satisfied 

 myself still further by breeding the moths. 



From eggs of C. spartiata forwarded by me to Mr. 

 Hellins in October, 1868, the larvae were hatched in 

 February, 1869, earlier probably than is natural to the 

 species on account of their not being exposed to the 

 cold, but the imago was not bred till the 9th of 

 October; the time for finding the larvae at large 

 appears to be the month of May or thereabouts, and

 Mr. Harwood on the 20th of July, and again on the 

 6th and 26th of September, 1869; the perfect insects 

 appearing this year (1870), the earlier batch between
