antennas hardly half as long as the body, neatly setose, base short, 

 flagellum sparingly longer than base, joints not oblong, cylindrical, 

 setae verticillate and nearly twice longer than joints. Superior 

 antennae nearly half shorter than base of inferior. First pair of feet 

 minute, hand subtriangular, apex truncate and a little excavate. 

 Hand of second pair stout, quadrate, a little oblong, apex nearly 

 straight truncate, the palm of the hand consequently transverse, or 

 but slightly oblique, somewhat excavate. Third and fourth pairs 

 weak, subequal; fifth, sixth, seventh similar, very unequal, but 

 gradually increasing in length; fifth half shorter than seventh, 

 setaa of fifth joint numerous, rather crowded, and exceeding the 

 diameter of the joint in length.

Length, seven lines. Head but little longer than first thoracic 

 segment. Epimerals short. Last joint of base of inferior antennae 

 but little longer than preceding, joints of flagellum not longer than 

 breadth, and as large at base as at apex, setae six or eight in a 

 whorl and mostly longer than the joint. The hands of the second 

 pair are oblong quadrate (the two equal), and the finger closes against 

 the broad transverse apical margin, leaving a space between it and 

 the palm, the length of the palm equalling the breadth of the hand, 

 and being three-fourths as long as the hand ; the carpus is very short 

 and is not produced below between the hand and third joint. The 

 setae of the posterior legs are in close clusters or whorls, though short, 

 and there are seven or eight sets on either margin of the fifth joint of 

 the seventh pair. The first pair of caudal stylets have the outer 

 branch naked above.
