c? ? . A ver}' variable insect ; always distingiiislipd from fiif{f. fwiformis by 

 the darker colour of the wing-borders, the thinner bar npon the cross-veins of the 

 forewing, and the oliviously pale side of the thorax, or the very heavily dentate 

 wing-liorders. The external border of the hindwing is mostly thinner than in the 

 western form, and there is (always ?) a transparent streak in the abdominal border, 

 very seldom fonnd in Jui-if. jHciformis. ( 'crtain small specimens come very near 

 (/nnsswnsis. 



S. Process of i>enis-sheath longer than in f/icif. fiiciformis, not qnite so broad. 



There are two very dift'erent-looking forms, hitherto considered specifically 

 distinct. As they are strnctnrally the same, and are, moreover, connected by inter- 

 gradations, we have no doubt that they are the same species. Wc keep the two 

 extreme forms and the intermediate one separate, as follows : —

(??. Always large : thorax and abdomen above brighter yellow than in the 

 previous, reminding one of /y/r/w«.s ; sides of thorax generally not paler than 

 middle : border of forewing heavily dentate ; underside of abdomen mostly with 

 little grey scaling, last sternites reddish, with pale mesial line. 



This is apparently the commoner form in summer.

The first form not yet known from China ; the second not seen from Jaj)an ; 

 the third common in Japan, occurring also in Corea, not qnite typical in Amnrland 

 and China.
