cj 9 . A very variable insect ; always (listiiiguishcd from fnfij. fucifonma by 

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

 forewing;, and the obviously |)al(> side of the thorax, or the very heavily dentate 

 wiufij-liorders. The external border of th(( hindwiuf^ is mostly thinner than in tlie 

 western form, and there is (always?) a transparent strealc in tlie abdominal border, 

 very seldom found 'u\ fiirif'. fiieiformiK. Certain small specimens come very near 

 (l<inM>irt)sis.

There are two very ditferent-looking forms, hitherto considered specifically 

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

 gradations, we have no doubt that they are the same species, ^\'c keeji the two 

 extreiiie I'orms aud the intermediate one separate, as follows : —

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

 jirevious, reminding one of radians ; sides of thorax generally not jialer than 

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

 little grey scaling, last stornites reddisli, with pale mesial line. 



This is njiparently the commoner form in summer.

The first form not yet known from China; the second not seen from Japan; 

 the third common in Japan, occurring ;ilso in Corea, not quite typical in Amurland 

 and China.
