small neck ; also exceedingly sluggish and slow in its 

 movements. 



On Lotus cnrniculafus from June to August, and, after 

 hybernation, in April, when it does not eat. But in those 

 cases in which a second emergence takes place, a number of 

 the larvas must feed up rapidly in June and July, and a 

 second generation viai/ feed in September and October. 



Hiibner figures and DajDonchel describes the larva, however, 

 as " pale green with a yellow line on each side and a row 

 of black spots above each," while Berge says "pale green 

 with yellow dorsal and lateral lines," and Dr. Lang figures 

 a larva answering to this description, but otherwise agree- 

 ing closely with the larva as known here. It is, therefore, 

 I^robable that it has at times yellow, instead of green, longi- 

 tudinal lines. Berge indicates, besides Lotus rorniadafv.s. 

 Eryngmm campcstre as a food plant, a statement which 

 appears somewhat improbable. 



The PUPA, as figured by Lang, is blunt in front with no 

 projection; rounded, and tapering gently to the tail; red- 

 dish-brown on the back, greenish beneath, with the wing 

 cases distinctly dark gTeen. Newman says, " smooth, without 

 angles ; thoracic segments swollen and of a dark green colour ; 

 body conical, pointed, tinged witli rosy red (Hiibner)." 



This species has been reputed to be double brooded in 

 this country, appearing in May and August — as it certainly 

 does on the Continent of Europe — and upon this point I 

 have been at some pains to procure information. Mr. 

 Sydney Webb says that it is certainly double bi'ooded in the 

 Dover district, totally disajjpearing between the two emer- 

 gences. ]Mr. W. R. Jeffrey confirms this with regard to 

 Ashford, Kent, stating that he has noticed how completely 

 the species had disappeared before the end of June, but 

 finding it again, in diminished numbers, in August. In my
