NOTES AND OBSERVATIONS. 321 



coloui'ed female. Two other specimens were seen on the wing in other 

 parts of the town. The ova from which these originated must have 

 been laid by a female which had wandered from its native haunts, or 

 by a specimen which escaped or was liberated after pairing. In any 

 case, these occurrences seem worth recording. — W. H. Harwood ; 

 94, Station Road, Colchester, September 8th, 1911. 



PiERis RAP^ AND P. NAPi Triple-brooded IN 1911. — Third broods 

 of Pieris rapce and P. napi abounded at the end of August, and are 

 still common. — W. H. Harwood ; 94, Station Road, Colchester, 

 September 8th, 1911. 



Specimens of a third brood of P. najn and of P. rapce were to be 

 taken in Northamptonshire in mid August, the second brood appear- 

 ing as early as the hay harvest. — Charles Mellows; Bootham 

 School. 



A male specimen of P. rapce emerged on August 30th, and a 

 female on September 3rd, both from larvae reared in the garden here. 

 Other larvae fed up at the same time, and duly pupated, but up to 

 this date (September 13th) no more butterflies have appeared. — 

 H. Garrett ; 21, Angell Road, Brixton, S.W. 



I have noticed fresh specimens of Pieris rapes on July 5th (female) 

 and September 5th (male and female) at St. Anne's. Is not the 

 latter probably a third brood ? — J. W. Muirhead ; 31, Fairhaven 

 Road, St. Anne's-on-the-Sea, September 5th, 1911. 



Vanessa io Double-brooded in 1911. — On September 6th I 

 found a large brood of nearly full-fed V. io larvaa feeding on a patch 

 of low nettles which had been mown off and were freely springing 

 up again. So far as I know, the only other recorded second brood in 

 Britain is that mentioned in South's 'Butterflies of the British Isles.' 

 — W. H. Harwood. 



Third Brood (?) of Papilio machaon. — The exceptional summer 

 seems likely to produce three broods of P. viachaon this year. In 

 previous years I have always obtained half-grown larvae of the second 

 brood at Hickling about August loth. This year, on the same date, 

 I found eggs and young larvae from females of the second generation, 

 and these are already (September 1st) nearly full-grown. — C. Mel- 

 lows ; Bootham School. 



Agrotis exclamationis in September. — I obtained three perfect 

 specimens of A. exclamationis at sugar on September 8th last. Is 

 this species normally double-brooded ? — J. S. Carter ; Iden, Sussex. 



[Agrotis corticea has been occasionally noted in September, but we 

 do not recall any record of A. exclamationis having been captured in 

 this month. In 'Barrett,' however, there is a record of a casual 

 emergence of the last-named species in October. — Ed.] 



Hadena pisi in September. — Eight perfect specimens of H. pisi 

 came to sugar on September 15th. — L. W. Newman ; Bexley, Kent. 



Larva of Arctia caia FuLL-GROveN in September. — Tliree larvae 

 of .4. caia weve found on September 16th while searching for Pyrameis
