Tlie inflexed portions of the 3rd and 4th longitudinal veins are 

 considerably curved, exactly as in 21erodon. A. hifascia is closely 

 allied to scuteUaris but is quite distinct, the differences lying 

 in the rather less prominent face, the aeneous spots en the 2nd 

 abdominal segment (which since my description of the species 

 have become very faded), the distinctly broader apical part of the 

 abdomen (which in scuteUaris is bluntly conical), the yellow 

 pubescence at the sides of the abdomen (which is whitish in 

 scuteUaris) and the tmiformly brown legs, which in scuteUaris 

 are black with the basal half of the posterior tibia) yellow.
