white and spiny. Apices of tarsal joints with 3'ello\v, spiny liairs. Tibial spurs 

 long, dark yellow. Claws ferruginous to yellow, apically cleft. First joint 

 of hind tarsi rectangular, about four times as long as broad. 



Genitalia — (Fig. 76.). Stipes stout, notched; apex very short and blunt, 

 covered with tuft of long hair. Inner margin of middle portion with few 

 long hairs. Sagittal rods long, extending one-fourth of their length beyond 

 the stipites. Membranous wing extending back to near the end of the volsella. 

 \'olsella very large and prominent. Seventh ventral plate very small and 

 broad ; each wing extending diagonally outward, instead of straight forward. 

 Entire anterior portion haired. On the inner margin of the basal portion is 

 a sort of ridge, crowned with a row of long, curved spines. 



This species may be found to be near C. prosopidis Ckll., or some allied 

 species. The very short malar space would indicate that it is not C. prosopidis, 

 however.
