 of taps occupied an average time of ahnost exactly ten seconds each 

 is ample proof of their multiplicity. — Claude Morley. 



Emergence of the Second Generation of Eustroma (Cidaria) 

 siLACEATA. — -Two batches of ova of E. silaceata deposited by females 

 of Huntingdonshire origin were received in May last. Larvte from 

 one of these batches commenced hatching out on May 21st, and from 

 the other a week later. On June 16th, the larvae, about fifty in 

 number, were transferred from boxes to a roomy breeding cage, and 

 pupation began a few days later, but it was not until about July 6th 

 that all the larvae had spun up. 



A female moth emerged on July 2nd, and another example of the 

 same sex appeared on the 4th ; between the latter date and August 

 3rd seventeen specimens in all had emerged. On August llth, 

 twenty-six pupae were removed from the breeding cage and placed in 

 a glazed tin box. At this time a few eggs and several eggshells were 

 found fixed to shreds of dried foot-plant {Epilobium) at the bottom 

 of the cage. The eggs were placed in a separate box but only one 

 larva hatched therefrom, and this would not feed. Between August 

 21st and September 14th seven males emerged, and on the 17th an 

 example of each sex appeared in the box (pairing was not observed, 

 but eggs were laid during the nights of the 18th, 19th, and 20th). A 

 male emerged on September 16th, followed by a female the next day. 

 On the date last mentioned there were still about a dozen pupie but 

 no other moth emerged therefrom until October 9th, when a female 

 appeared. The remaining pupae did not exhibit any indication of the 

 emergence of moths up to Nov. 7th, but between that date and the 

 morning of Nov. 20th, when they were again looked at, two females 

 had emerged ; one was dead but quite limp, the other very much alive 

 and apparently just out. 



From the ova deposited September 18th-20th larvae hatched out 

 September 28th to October 6th, and all but one had pupated by the 

 end of October ; the laggard was seen alive on November 3rd, but it 

 was found dead on the earth under a leaf on November 7th. 



As will be seen from the above jottings, moths of the second 

 generation have been emerging, one or two at a time, over a period 

 of twenty weeks ; and curiously the first two imagines (July 2nd 

 and 4th) and the last two (between November 7th and 20th) were 

 females. — Eichard South. 



Eetarded Emergence of Venilia maculata, L. — In 1906 I 

 obtained ova from a wild parent taken in this district, larvae 

 hatched, fed up, and successfully pupated. Several imagines emerged 

 in 1907, a few in 1908, and just a few more in 1909, the latter having 

 lain over for three years. The breeding-cage in which they were 

 reared contained no other species ; it was kept in a cold room and in 

 the same place throughout. I can find no previous record of this 

 species having lain over in the pupa state even for a second year, 

 which makes the fact of some having lain over a third year the more 

 worthy of record. — ^W. A. Eollason; "Lamorna," Truro, Cornwall, 

 December 13th, 1909.
