common web; and very interesting anecdotes relating to some 

 of the species are given by Reaumur, and Kirby and Spence. 

 Some of the females deposit their eggs in a compact ring, round 

 the twigs of trees and plants. 



The following are British insects. 



1. C. Neustria Linn., Haw. — Don. 3. 95. ? . — mr. bilineatus 



Haw. 

 The handsome caterpillars of this insect present themselves 

 in June in every hedge and garden, doing sometimes incre- 

 dible mischief to the fruit trees ; they have been very abundant 

 this year in the neighbourhood of London : the moths appear 

 in July and August. 



2. C. castrensis Linn. — Curtis Brit. Lnt. pi. 229. 



It is with great satisfaction that I lay before my readers so 

 complete a drawing of this local insect, which was discovered 

 many years since in great abundance in the Isle of Sheppey 

 by Mr. William Curtis. I was indebted to the late Mr. E. 

 Blunt for the caterpillar ; and to Mr. C. Parsons for the loan 

 of the moths and the following account. 



" In the beginning of May 1827, in an island on the Essex 

 coast, called New England, I found some larvae of Bomhi/x 

 castrensis newly hatched, and feeding on the Sea Wormwood. 

 I took them home and was careful to supply them daily with 

 fresh food, but in the course of a week they all died. In the 

 beginning of the following July I again found the caterpillar 

 feeding on Artemisia maritima, Plantago lanceolata, and 

 Dauciis Carota. With these I was more fortunate ; for about 

 the middle of the month (July) they retired into the pupa 

 state, and on the 10th of August a female of the moth ap- 

 peared, and about a week after a beautiful male. The last I 

 bred was on the 22nd of August. It is a difficult insect to 

 rear, as the larvae if taken before they are nearly full fed, pine 

 and die ; and half of what I had in pupa did not come out. 

 The male is the rarer sex, the specimen figured being the 

 only one I have seen." 



3. C. Crataegi Linn., Haw. — Don. 4. 117. — Sepp. 2. 25. — Mali 



and Avellanae Fab. — var. pallidus Haw. 

 The caterpillars are found in May and June, on Willows, 

 the Black and White Thorns; and the moths appear in August 

 and September. 



4. C. processionea jLiVm., Reaum. — Kirby and Spence, 1. 131 



& 473. & 2. 23. 



This species is recorded by Stewart; and in the British 

 Museum is a specimen, I believe, which Dr. Leach sent from 

 Devon. 



The plant is Artemisia maritima (Drooping Flowered Sea 

 Wormwood).
