lis 



both in the larval and the imaginal states, the cocoon is hidden on 

 or near the ground, while that of jialiistris is alwaj's high up. 



" This is not due to any special conditions, for early filipenchda', 

 on the same ground as trifolii-iuinnr makes a cocoon high up on 

 grass stems. 



" This difference of habit seems to me of more importance than 

 slight differences of appearance in such a variable genus as that of 

 Aiithrocrra." 



Mr. Robert Adkin confined his remarks to the liippocrepidis 

 question. He said that forms of at least three species had been 

 described under this name, and it was therefore desirable before 

 entering upon a discussion that we should know just which form 

 we were talking about. First, there is the insect described by 

 Hubner, which is now generally regarded as a form of Anthrocera 

 transaljiina, Esp., a six-spotted species somewhat resembling A. 

 filipendnla: in superficial appearance, but differing from it in 

 essential details. This same form was also described by Ochsen- 

 heimer, and figured by Herrich-Schaffer, figs. 54 and 55, where the 

 underside of the forewings shows the red markmg as one large 

 blotch, covering the greater part of the area of the wing, not as 

 well-defined, red spots on a pale reddish ground as in A. filipendulcB. 

 He also figures a yellow form, fig. 56, while Hubner figures a 

 yellow and a pink form, all being under the name hippocrepidis and 

 all apparently bemg referable to A. transaljiina. Then there is 

 hippocn'pidis of Herrich-Schaffer, figs. 52 and 53, a form of A. 

 ephialtes, L., another six-spotted but very distinct species, among 

 other marks of differentiation being its red-banded abdomen. 

 Neither A. transalpina nor A. ephialtes, nor any of their forms, are 

 known to occur in Britain, and may therefore be dismissed from 

 our present consideration. 



The third hippocrepidis is that mentioned by Stephens, who 

 described it from specimens which he says he took " in a field near 

 Coombe Wood, on 20th June, 1810, and subsequently near Darenth 

 Wood." He also mentions a yellow form bred from larvae found 

 on wild liquorice near the latter habitat. In his description he 

 says that it "varies in size like A. jilipendnUc, which it greatly 

 resembles ; but the border of the posterior wings is considerably 

 more distinct than in that insect, and undulated internally ; the 

 sixth spot on the anterior wings (the one towards the anal angle) is 

 generally small, with a coloured nervure passing through it ; the 

 under surface of the anterior wings with the disc entirely red, and
