and hind wings, which is yellowish-buff, instecad of white. The 

 black and brown markings coincide with the type. The head and 

 collar are deep tawny-buff. The typical white markings on the 

 thorax, legs and antennae are replaced in this specimen witli buff. 



This specimen was taken at rest on a tree trunk at Delamere, 

 April 12tb, 1919. 



(^ . Crocallis elinguaria, Linn., form signatipennis, form. nov. 

 The ground-colour of the fore wings is decidedly dark buff and the 

 cross lines which form the border to the brownish band are united 

 together at the inner margin, forming a relatively sharp point ; thus 

 the whole outline of the transverse band, together with the large 

 discal spot, strongly resembles the head and bill of an anserine bird. 

 When placed with a series of typical examples, the peculiar form of 

 the transverse band is very noticeable indeed. 



Crocallis elinfiuaria, Linn., is, as is well known to collectors, 

 given to slight variations in the ground-colour and the transverse 

 lines, also in the absence of the marginal dots, but one fails to 

 find reference to any marked variation in the shape of the trans- 

 verse band. 



The specimen was bred from a larva taken at Delamere; the 

 moth emerged in July, 1918 (Fig. 2). 



(J. Nyssia zonaria, Schiff., form ochracea, form. nov. The 

 markings on the fore and hind wings are as in the type ; the ground- 

 colour, instead of being white to greyish, is a pale yellowish-buff and 

 in this respect differs from the type. 



This specimen was taken on April 20th, 1919, on Wallasey 

 sandhills.

Pieris hrasslca and P. rapce. — The second broods of these two 

 butterflies were swarming from the middle of July well on into 

 August. Sometimes the air has been literally alive with them. 

 On hot, bright days, after the water-carts have gone round I 

 have seen them settling iu bunches on the road drinking the 

 water and fluttering and fighting to get to the wettest parts. It 

 was a very interesting sight. 



Eucldoe cardamines. — Last July the larvse of this butterfly 

 were not uncommon in the lanes at Instow, North Devon, feeding 

 upon the seed-pods of the common charlock {Sinapis arvensis), 

 and I took three or four dozen of them. The perfect insects 

 emerged here during May and were set at liberty in our lanes, 

 and whenever I released a female she attracted and became 

 mated to a wild male in less than five minutes. I never 

 released a female until I saw males about. The North Devon
