— 1 double 2 ; male without special armature below 



hind femora (only male known) 34. insons Lundbk. 



Of the above species two, included under the species with short 

 costal cilia, viz rudis and depilata^ have the cilia nearly midway 

 between short and long, and in two others, basispinata and insons 

 the larger bristle on mesopleura is rather small, especially in basispi- 

 nata it is small, so that this species perhaps might be sought in the 

 group with the bristles uniform.
