Since I luue published the Aphidiclae of Japan '\ I have found 22 new 



«i-)ecies and ; new jjeiiera belongin<j to the subfamily Aphidinae, and I shall describe ' ** 



them in the present paper. I shall also enumerate in this occasion some species tH.iTA'^ 



which were not known to our fiiunal rei;ion. ■'AJ<U 



1. Metaphis n. g. 



Allied to Yamataphis Mais., but differs from the latter as follows : 

 Anterhinarial of the antennae scarcely shorter than the 4th joint, the 3rd 

 joint much longer, nearly as long as the 4th and 5th taken together. Media of 

 the fore-wing always 2 branched. Cauda large, much broader than the cornicles, 

 longer than wide. Cornicles longer and larger, near the ape.x more dilated. 

 Genotype. — J\Tc/afi/ns angelicae Mats. 



1. Metaphis angelicae n. sp. (Pi. I. f. ^, a, b; c.) 



Winged vivi|)arous female — Bod\' oblong, head and thorax brownish, the 

 rest greenish yellow. Antennae somewhat infuscated, the 3rd joint with numer- 

 ous granulous sensoria; anterhinarial nearly 9 times as long as the postrhinarial. 

 Wings hyaline, veins and stigma pale testaceous, 2nd furcal nearly at the two- 

 thirds part of the first near the apex. Cornicles clavate, at the base much con- 

 stricted, Cauda nearly twice as broad as the base of the cornicle, with short hairs 

 on the sides near the ape.x.
