riERID.K. 39 



newly emerged and not hybernated — and were seen in 

 greater numbers than those of the 'previous autumn. (I 

 understand that at Gravesend tliey were observed at the same 

 date.) These were on the wing until July 4th, but had 

 then become shabby, the females worn to rags ti'om constantly 

 fluttering among the grass and Lotus. On August 11th 

 another brood appeared on the wing, and in a few days every 

 clover field, lane, and roadside was gay and lively with the 

 pretty creatures. Whether the multitudes then observed all 

 over the country were solely the offspring of the earlier 

 emergence in this country, or were reinforced by a vast 

 immigration from abroad, must always remain doubtful. 

 Although the species made a vigorous effort to maintain 

 itself in that year, and succeeded in producing another 

 generation on the Kentish coast, its occurrence throughout 

 the country has again become only casual and sporadic. 

 The inference is, that eggs were deposited, but that the more 

 inclement winter destroyed the resulting larvae, since there 

 was nothing to prevent hybernated females, had there been 

 any, from reproducing in the following year. 



The resemblance to a yellow leaf is as great in this species, 

 when at rest, as in the preceding. 



It is useless to give localities. Doubtless it has been 

 found in every county of the three kingdoms as far north as 

 Orkney. There appears to be no record for Shetland. 



Of extremely wide range in temperate regions, extending 

 to Japan. 



Genus 6. GONEPTERYX. 



Antenna red, short, curved, thickened to the apex. 

 Wings angulated, not dark-margined. Body covered with 

 silky white hairs. 



Larva downy, somewhat tapering. 



I'lTA with projecting wing-sheaths.
