 Cryptoripersia, Ckll., which will be distinguished by the possession of a 

 complete subpyriform brittle sac. The following measurements in /x /x 

 will assist in the recognition of Ripersia arizonensis : Anterior leg : 

 femur, 1 16 j tibia, 83; tarsus, 6c. Antennal segments: (i) 41, (2) ;^;^, 

 (3) 33> (4) 25, (5) 33, (6) 61.-T. D. A. Ckll.]
