1. Metaphis n. g. 



Allied to Yaniataphis Mats., 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 apex more dilated. 

 Genotype. — Metaphis aiigelicae ]\Iats. 



1. Metaphis angelicae n. sp. (PI. I. f. 5, a, b; c.) 



Winged viviparous female — Body 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 apex.
