^ I ha\-c not seen the original description of tliis species. The 

 specimen before me is a little smaller but somewhat similar in color to 

 O. dcgccrn Kirby. The head in profile is more slender and the apex 

 turned slightly dorsad, the antenna has two long processes, one reaching 

 to apex of head and the other a little shorter. Medio-ventral edge of 

 pygophor roundly produced into a small plate, a depression runs across 

 the base of this plate which gives the margin the impression of being 

 entire, lateral edges roundly produced; anal segment long, narrow, apex 

 curved slightly ventrad and rounded, anus near apex, lateral edges 

 turned ventrad, the basal half subangularly produced ; genital styles 

 widely apart at bases, ventral edge sinuous, apex produced into a point 

 and turned dorsad, dorsal edge entire, straight.
