The genitalia are almost exactly like those of mutator. The 

 teeth of the harpes are stout and strong, from 7 to 10 in 

 number. The setae on the basal appendages are distinctly 

 longer, being rather long as opposed to short. The basal hooks 

 are regularly recurved, not much widened and with pointed 

 tips. The differences, however, are so inconsiderable that I' 

 would be inclined to overlook them, except that the larvae differ 

 rather conspicuously, as can be seen from comparison of the 

 figures quoted. The difference in the head-hairs cannot be 

 unimportant. 



The species is rather common in Panama.

Clasp-filament narrowly snout-shaped, a crest of very short 

 pile running to tip; spine widened and appendiculate. Outer 

 division of the lobe of the side-piece slenderly columnar, 

 widened at tip ; a short inner arm bearing a long filament with 

 hooked tip and a small delicate one ; middle filament broadly 

 blade-shaped, long; on the outer aspect of the tip, a large 

 broadly expanded leaf and two blade-like filaments, not as 

 long as the leaf. Inner division of lobe of side-piece with the 

 arms well separated, the outer long, the inner short, each 

 bearing a long stout filament with curled hooked tip. Second 

 plate of unci furcate, each limb pointed ; a curved horn arising
