In June 1911, ova were sent me from Lapland by Mr. W. G. 

 Sheldon from P. vapi vai-. hryoniae females. Tlie resulting 

 pupae produced two males in August last, and the rest of the 

 specimens emerged this spring. The two which emerged last 

 summer have the green veinings on the under sides much less 

 marked than in the spriug ones. The others show a fair 

 amount of variation both on the upper and under sides. 



Dr. T. A. Chapman found in June 1911, in Glarus, 

 Switzerland, typical F. napi, and also the var. hryoniae, flying 

 together on the same ground in the Lintthal, and kindly sent 

 me females of both forms. 



Fi'om the typical females nothing but P. napi emerged 

 from a laige number of resulting pupae. Some emerged last 

 August and the remainder this spring, the series showing the 

 usual seasonal dimorphism. 



From the bryoniae females a large number of pupae 

 resulted, and three of them produced, last August, very 

 strongly-marked specimens (females), very different from 

 those which emerged this spring. I had always considered 

 this form to be single-brooded, and had frequently bred large 

 numbers with my late friend Mr. Harrison, all of which always 

 emerged in the spring. These three have the same shape of 

 wings as the summer emergence of the P. napi, the markings 

 on the upper sides are also more pronounced, and the veinings 

 on the under sides less pronounced than in the corresponding 

 spring emergence specimens, as in the case of the two series of 

 the typical P. napi. 



Some of the males show a black spot on the disc of the 

 fore wing. They can be separated roughly into two series, 

 those with no yellow and those with more or less yellow on 

 the under side of the wings. A parallel variation of the under 

 sides occurs in the females, and their upper sides show a con- 

 siderable amount of variation in the pi-oportion of the dark 

 scales on the area of the wings and along the nervures. 



Coleopterous lakvae. — Mr. K. G. Blair exhibited larvae 

 oi Cehrio sp. (l yigas, Fabr.) from Sicily, received from Mr. 

 J. P. Barrett, per Mr. H. Main. 



The larvae were dug up in a patch of potatoes in a garden 

 at Messina, and he heard from Mr. Barrett that this patch
