CAPTURES AND FIELD REPORTS. 293 



of an inch in length when resting. One larva spun up on May 15th, 

 and all the others had prepared for pupation by the 28th of that 

 month. A female specimen emerged on September 9th, followed by 

 two males and a female on the 14th. The seventh specimen (female) 

 appeared on the 25th. Forty-three eggs were deposited during the 

 nights of the 15th and 16th by the female that emerged on the 14th ; 

 these, which appear to be fertile, were laid loosely. Hellins, in his 

 excellent life-history of P. lapidata (E. M. M. viii. 165), states that 

 the larva he had under observation did not make a cocoon, but 

 merely spun a few threads of silk. All my larvae constructed cocoons 

 of silk, sand, and tiny stones ; in one case four of these were attached 

 side by side, and in another two. One I disturbed before pupation 

 had been effected, and the bottom of the cocoon being more tender 

 than the top, broke open and exposed the larva. The next day the 

 pupa was formed, and it was then of a light orange colour. Shortly 

 afterwards it changed to a rather pale chestnut red, with the wing- 

 cases slightly greenish for a time. Later it became reddish brown, 

 as are the empty pupa-shells at the present time. — Richard South. 



CAPTUEES AND FIELD EEPORTS. 



Hydrcecia crinanensis in Ireland. — During August last I was 

 fortunate enough to find specimens of Ilydrcecia crinanensis, of the 

 melanic form, near Londonderry. They were taken about the end of 

 the month. Mr. Pierce has examined all the specimens, so there 

 can be no doubt as to their being correctly named. — H. R. Sweeting. 



Occurrence of yEschna isosceles, Miill., near King's Lynn. — 

 On June 15th of this year, a large dragonfly flew into a house about 

 three miles from King's Lynn, and was lorought to me two days 

 later. From its early appearance, I at once thought it to be JEsdma 

 isosceles, and a reference to Mr. W. J. Lucas's work on British 

 Dragonflies soon convinced me that it could be none other than a 

 female of that extremely local species. The Norfolk Broads, so far 

 as this country is concerned, must, I suppose, be considered the 

 home of this fine insect ; but so far as I know this is the first time it 

 has been met with in this part of Norfolk. — E. A. Atmore, F.E.S. ; 

 King's Lynn, Norfolk, September 19th, 1910. 



Lepidoptera at Chiswick and Barnes. — With the exception of 

 three species, lepidoptera have been scarce here this season. Graci- 

 laria syringella has been perhaps more abundant than usual, and I 

 have seen a larger number of Crambus culmellus than I remember 

 previously, though this species is usually very abundant. The third 

 species, which has been more common this year, is Bryopliila perla. 

 On a wall, where I usually see two or three specimens, I counted 

 twelve, on August 24tli. I have never seen any but the grey typical 

 form here. At Barnes, August 31st, I saw a fine fresh example of 

 Acronycta megacephala. — Alfred Sich ; Chiswick. 



Senta Maritima in Surrey. — In confirmation of Mr. Percy 

 Richards's note (Entom. xliii., 251), I should like to add that I took 

 three specimens of Senta maritima iulvce) on July 17th of this year,
