wildly in the sunshine, but the females sitting on the tansy plants. I 

 am still unable to find out the food plant of the moths, apparently 

 undistinguishable from this species, which are found rather commonly 

 along the coast in places where there certainly is no tansy. 



Dichrornmplia consortana, Steph. The first hint I received of the 

 food plant of this species was from Mr. Sydney Webb, who reared 

 one specimen from a flower-head of ox-eye daisy in 1874. It has been 

 since found by Mr. J. W. Threlfall, of Preston, who very kindly sent 

 me larvse in 1877 ; but I have to confess, with much perplexity, that I 

 have searched the ox-eye plants with great care for the last two seasons 

 in fields where the moth occurs, without even finding a larva. My 

 description is from those sent by Mr. Threlfall — short and thick, but 

 shortly attenuated at each extremity, colour pale yellow, internal dorsal 

 vessel visible as a brown blotch within the 10th segment. Head and 

 dorsal plate brown, anal plate hardly visible. Eating in June into the 

 growing shoots of Chrysanthemitm leucanihemxun^ just below the buds, 

 and causing the shoot to become thickened and distorted, feeding on 

 the pith, and sometimes eating out the buds. Pupa brown, spun up 

 between the burrow, from which it projects when the moths emerge, 

 from the middle to the end of July. 



Gatoftria Jii/pericana,J{iib. The food plant and habit of the larva 

 of this species are well known, but the larva does not seem to have 

 been described with us. 



"When young, it is pale yellow or pale grey, with a tinge of liver- 

 colour on the back, head and dorsal plate shining black, anal plate 

 yellowish edged with black. When nearly full grown, short and 

 stout, smoky or blackish-brown, rather paler at the sides, head light 

 brown, dorsal and anal plates black. When full fed, the colour fades 

 a little. On Hypei'icum perforatum, Aravim^ together and twisting up 

 the terminal leaves of the young shoots, and feeding in the heart. 

 The top of the shoot is nearly always twisted over to one side, and so 

 completely eaten out, that it withers and turns brown as soon as the 

 larva has deserted it, either to enter a fresh shoot or to spin up among 

 rubbish. It feeds from the middle of April through May, and the 

 moth appears early in June. 



Hofmann gives a careful description from Treitschke — " short, 

 " thick, wrinkled, dirty white, with small undivided single-haired 

 " raised dots. Head honey-yellow, dorsal plate shining black, with a 

 " pale border. In May and June, spinning together young plants of 

 " Hypericum perforatum. Pupating in the earth."
