Hab. Formosa {Sauter), 6 $ , 3 cJ, in Berlin Museum. 



The genus is new to Formosa. In its broad head this 

 resembles A. vitiosa, Smith, from China, but it differs iu 

 many other respects. There is also evident affinity with the 

 European A. labialis, Kirby. I possess only the male of 

 labialis, which is considerably larger than that oi formosana, 

 with the lateral face-marks longer and the abdomen duller 

 and much more hairy. The type of A. formosana is a 

 female.
