CAPTURES AND FIELD REPORTS. 259 



Vernet. Those with ■■'■ are not British. — W. J. Lucas ; Kingston-on- 

 Thames. 



Eaphidia maculicollis (Neuroptera). — In connection with my 

 note on this snake-fly [mitea, p. 129), I may note that I have 

 received a pupa from Dr. David Sharp, which he took at Braemore 

 in Scotkind in Jmie of the present year. This one is a female, and 

 an interesting point about it is that its long ovipositor is folded back 

 and lies closely pressed to the dorsal surface of the abdomen. — W. J. 

 Lucas ; Kingston-on-Thames. 



Longevity of Epinephele ianira. — I believe it is generally 

 considered that the Satyridse are usually short-lived butterflies, there- 

 fore it may be worth recording that a freshly emerged female E. ianira 

 I captured ^71 coitu on July 2nd last lived in captivity until Aug. 28th, 

 making fifty-eight days. — F. W. Frohawk. 



The Influence of Temperature on the Hatching of Lepidop- 

 terous Eggs. — As an example of the influence temperature has on 

 the development and hatching of eggs of Lepidoptera, the following 

 is a good instance. On May 30th last a Pieris brassiccB deposited a 

 batch of forty-one eggs during warm weather, but on June 2nd the 

 temperature suddenly fell many degrees, and cold, wet weather set 

 in and continued so for the next fortnight ; consequently, the eggs did 

 not hatch until June 16th, remaining in the egg state seventeen days. 

 At mid-day on August 10th, during fine and very warm weather, I 

 watched three P. brassica depositing ; in all, five batches of eggs were 

 laid. All these hatched on August 15th quite early in the morning, 

 the egg state lasting only four and a half days, due to the w^eather 

 remaining exceptionally v/arm throughout, thus making a difference 

 of twelve and a half days in the time of hatching. — F. W. Frohawk. 



Gynandrous Abraxas grossulariata ab. Varleyata. — Of the 

 only two specimens of wild Abj-axas varleyata I bred this year, tlie 

 produce of seven hundred collected pupte, one has both the left-side 

 wings male, i. e. with the usual white rays characteristic of the sex, 

 but the right-side wings female, i.e. without white rays, as is usual 

 in that sex. x\pparently it is a gynandrous specimen. — Geo. T. 

 Porritt, Elm Lea, Huddersfield, September 4th, 1909. 



CAPTUEES AND FIELD EEPORTS. 



Sugar a Failure in June and July. — Mr. Everett (antea, 

 p. 235) notes the scarcity of moths during the months of June 

 and July in Cambs. My experience has been similar. I have 

 "treacled" night after night without a single moth visiting the trees. 

 This could hardly have been due to bad weather, as I caught a good 

 number at "light " in these months, and treacle paid well from the 

 middle of August to the beginning of September (I took about fifty 

 on twelve trees on August 26th), although the weather has been 

 almost as bad as in June and July. I think that as flowers have 

 been abundant this season, in spite of the bad weather, the moths 

 may have found them more attractive than artificial sweets. — -
