c??. Closely allied to the preceding species. A greyish mesial band from 

 raesonotum to end of abdomen ; the latter bnjwn above, without black basal patch, 

 an obscurely marked greyish dorso-Iateral stripe from segment ;5 backwards. Lines 

 1 and 5 of forewing heavy, 2 fused with 1, lines and 7 also rather heavy, inter- 

 spaces between 1 and 5 ])ale, between o and 6 dark. The black basal area of the 

 hindwing much more restricted than in alecto, not dilated distad before abdominal 

 margin. 



Genital armature as in olecto, but the tenth sternite rather broader, more 

 obtuse, less curved ; process of barpe less slender, .somewhat spoon-shaped, twisted. 



Early stages not known.

c? ? . Dorsal lines of abdomen obscure. Discal band of forewing formed by 

 two separate lines, lines 1 and 2 being merged together, inters})aces between lines 

 1+2 and T) of nearly the same breadth. 



According to the dated material from Japan there is some seasonal variation, 

 the spring specimens being on the whole paler than the summer specimens. The 

 Amur individuals which we have seen in collections are unfortunately not dated,* 

 but both forms occur in Amnrland as well as in China. 



* Collectors of J'alaearctic Lcpidoptera gciicriilly do nut care to have the .specimcnr' e.xactly labelled. 

 Tlie bad inlluence in this respect of certain dealers is exerywhere felt. Our American brethren in 

 Entomologicis are mostly more advanced, even some of the dealers. One of the latter was quite 

 astonished that we, being Europeans, wanted the date of capture of the specimens ; such a request had 

 never been made of him by a European Continental Lepidopterist.
