 third antennal joint a little longer than fourth and fifth 

 combined; thorax densely clothed with long fulvous hair; 

 mesothorax dull and granular, scutellum faintly shining ; 

 area of metathorax triangular, poorly defined, its sides 

 smoother than the densely granular adjacent parts, and

 base obscurely rugulose ; tegulse dark brown, small and 

 covered with hair. Wings brownish-hyaline, stigma and

Hab. Japan (U.S. National ^luseum, 126). 



A well-marked species, running in Schmiedeknecht^s table 

 nearest to A. opaca, Morawitz, but differing greatly in the 

 colour of the pubescence. It is very much like A. trhnmerana 

 (Kirby) from France, and must be considered a member of 

 the same group. In addition to the colour-differences, 

 however, the sides of the upper part of the metathorax in 

 trimmerana are rather shining, with a distinct punctiform 

 sculpture, not entirely opaque and evenly granular as in 

 nawai.
