200 THE ENTOMOLOGIST. 



As I see the account of the larva of Cidaria populata is 

 very short in 'British Moths,' I send you some notes, made 

 by myself, on larvaj of it beaten off heather. The smallest 

 larvae were about three-eighths of an inch in length, and in 

 colour were yellowish white, with narrow white longitudinal 

 lines on the back and sides : when full-grown they were 

 about an inch long, and rather variable. One variety was all 

 purplish brown, with no perceptible dorsal line, but white 

 subdorsal lines ; on the back were six white A-shaped marks, 

 the apex pointing to the head ; the second segment had two 

 broad white longitudinal lines on the back ; there was a white 

 stripe on the outside of each anal clasper. Another variety 

 was uniform light putty-colour, with blackish dorsal line, in 

 some narrow throughout, in others expanding on every alter- 

 nate segment into a black dorsal patch ; spiracles black ; the 

 head was small and flattened. When in confinement they 

 fed freely on willow-leaves : at rest the body was always kept 

 almost straight out, and if annoyed they fell off the branch 

 quite rigid. From the 26th of June to the 10th of July they 

 spun slight cocoons among their food, and in them changed 

 into pupa) about one-third of an inch long, of a dusky red on 

 the abdomen, and a black stripe down the middle of the back ; 

 the thorax and wing-cases were darker. The molhs emerged 

 from the end of July till the end of August. — J. Traill ;

Captures at Sieyning, Sussex. — I can quite corroborate 

 Mr. Button's statement (E^ntom. iv. 160) on the scarcity of 

 Colias Edusa on the Sussex downs this year. It seems to 

 me to be a very odd thing that this butterfly, usually so 

 common in these parts, should be so scarce, especially when 

 reports come in of its unusual abundance elsewhere. I pai'- 

 ticularly wanted some, and hunted hard for them ; yet I only 

 look one specimen, and I do not suppose I saw many more 

 than half-a-dozen altogether. LycKua Corydon, another 

 common insect here, was not by any means numerous this 

 season ; whilst L. Adonis was tolerably plentiful in August: 

 I see in your 'British Butterflies' you give May as the 

 month for its appearance, so 1 presume this was a second 

 brood, as the specimens I secured were in very fair condition 

 and of bright colour. Sphinx Convolvuli has visited this 

 locality, as I took three specimens at different times this
