Epimerals large. Superior antennae longer than half the inferior, 

 flagellam fourteen-jointed, joints sparingly oblong, setae partly very 

 short and divaricate, partly close appressed and about as long as 

 the joint. Inferior pair not half as long as the body, flagellum 

 longer than the base, sixteen-jointed, joints sparingly oblong, setse 

 numerous and verticillate, except on outer side which is naked, 

 setae hardly as long as breadth of joint. Feet of first pair quite 

 small, hand oblong, margins nearly parallel, below hirsute in part, 

 at apex obliquely truncate, finger short. Hand of second pair quite 

 large, subovate, arcuate above, palm very oblique transverse, spinu- 

 lous, ending in an angle below, finger a little longer than half the 

 hand, carpus small, not produced below between the hand and the 

 third joint, third joint triangulate anteriorly and nearly acute. Six 

 posterior feet subequal, increase gradually in length, setae few, one 

 stout one, as long as diameter of joint on fifth joint of fifth pair, 

 and one or two such on same joint of sixth and seventh pairs.

Length, five to six lines. The spiniform seta on the under side of 

 the fifth joint of the fifth pair of legs near its middle marks well the 

 species ; on the same joint of the following legs there are either one or 

 two such spines. The posterior apex of the third and fourth joints 

 in these legs is somewhat projecting, and set around with strong 

 setae. The under side of the flagellum of the inferior antennae is 

 rather closely or crowdedly setulous at the apices of the joints, and 

 the upper side is comparatively bare; but this character fails in the 

 younger specimens, three lines or less in length. 



One specimen is probably from Tierra del Fuego.
