versely, rather narrower in front than behind. Breast and 
legs with dense hoary pilosity ; femora reddish, becoming 
piceous at the tips; tibie yellow, the anterior and inter- 
mediate annulated with black; spurs geniculate, but not 
strongly so. Wings semi-vitreous, with slight fuscescent 
clouds; neuration yellow, strongly streaked and spotted 
with black; pterostigma opaque, greyish-yellow, marked 
with fuscous internally: in the anterior wings the costal 
area is occupied by two regular rows of pentagonal 
cellules, whereof those of the upper row are slightly 
smaller than the lower, the first seven or eight basal cel- 
lules simple. The abdomen of the ¢ terminated by a 
pair of short, broadly oval, blackish appendages, densely 
clothed with long black spiniform hairs turned inwards

I have a & without any indication of special locality. 
No doubt it is the same as the species recorded (but not 
described) by Hagen under the above name. He queries 
it as perhaps identical with the Spanish A. detica, Rbr., 
a species practically unknown to me, but I doubt not that, 
although allied, the two are distinct.

This pretty species—readily distinguishable by the 
oblique, semi-lunate, dark mark on the middle of the inner 
margin of the anterior wings, and the short, broad, dark 
streak near the apex of the posterior—appears to be 
common, and comes in all collections from Japan.

Body black. Antenne (mutilated), with the two basal 
joints yellow. Face and palpi wholly pale yellow; vertex 
swollen, with numerous small orange-yellow spots. Pro- 
notum longer than broad, scarcely narrower in front, with 
a deeply impressed transverse line anteriorly, and a broad, 
concave space posteriorly ; marked with orange-yellow 
spots irregularly arranged in three distant longitudinal 
rows; an indication of the two lateral rows is to be seen
