270 THE entomologist's record. 



the apex of the right fore wing. Mear the apex are about 50 



hlue scales, and amongst them are eight androconia. It is 



therefore a predominantly female gynandromorph. 



In conclusion Dr. Cockayne remarked that there was evidently a 



race of A. coridon producing gynandromorphs of predominately female 



type at Royston, and that the descent was probably direct. The 



evidence in favour of this view is that the genital organs in the majority 



of cases are those of normal females. It has been previously shown 



that there is evidence of direct descent of predominantly male type of 



gynandromorphism by Schultz who bred 4 Lijuiantria dispar, which 



were male in all respects except for splashes of female colour on the 



wings, from 85 pupte. One of these males was paired with a normal 



female, and out of 65 pupjie of the brood, 2 similar gynandromorphs 



were bred. 



Mr. H. E. Page exhibited a series of local races of Plcbciits an/us 

 (aeifon) from Abries in the French Alps, Sion and Berisal in the Swiss 

 Alps, and from Pajares and Brafiuelas in Spain. The last were of the 

 remarkable form named by Dr. Chapman as var. casaiacus, and were 

 taken by Mr. and Mrs. Page in August, 1914. 



Notes on the Season's Collecting, 1914. 



By HAROLD B. WILLIAMS. LL.B. 



I am anxious to avoid writing anything in the nature of a diary, 

 but some of my work this season may be of general interest. It will 

 perhaps be better to deal shortly with each of the species to be men- 

 tioned in turn than to attempt a chronological account. 



Riiiiiicia pJdaeas. — The first brood was very abundant on Wimbledon 

 Common on May 17th and 18th, and a number were overhauled. Two 

 nice minor aberrations, both females, resulted. One is an extreme ab. 

 coerideopnnctata; Stand., with four large blue spots in each hindwing. 

 It has also a pallid area in each forewing (upperside) and on the vinder- 

 side an extra spot between the two inner discal spots. The second is 

 a strongly marked underside, ab. infra-extensa, Tutt. 



On July 18th I found the first examples of the 2nd brood, at Rick- 

 mansworth, and on July 25th they were common at Chingford. 



On August 21st I took a S specimen in North Herts with the 

 whole of the left forewing, except the costal area, white. The usual 

 spots are present and as intense as those on the normally coloured 

 rightwing. 



Between September 21st and September 27th I found the Brd brood 

 abundant o)i Wimbledon Common, and numerous interesting speci- 

 mens Avere taken, of which the following call for mention : — A J ab. 

 obxoleta, Tutt, the hindwings entirely black ; two ? ab. radiata, Tutt, 

 the band in the hindwing replaced by five pencil-like dashes; and a $ 

 with the left hindwing small, about three-quarters the size of the 

 right hindwing, and the band of a straw colour. 



Aiiuiijdia popidi. — During the first week of June I obtained a large 

 batch of ova from a wild Clapton 5 , taken in cop. The larvae fed up 

 rapidly on poplar and pupated from the middle of July onwards. 

 Between July 29th and August 8th sixteen specimens emerged. On 

 August 2nd I was fortunate enough to breed two gynandromorphous
