hairs are slightly clavate and very conspicuously ringed, those in 
the first and third rows are short, in the second row a little longer; 
in the fourth row the submedian pair is wanting in my specimens, 
the intermediate pair is a little more than half as long as.the;eyes 
and twice as long as the sublateral pair. 
Antennæ (fig. 1a, in which the right antenna is seen almost 
from in front). Of the two elongate hairs on the fourth joint: the 
upper one is as long as the peduncle and twice as long as the 
other; both hairs are sharply ringed. The upper branch is slightly 
or not longer than the two distal joints of the pedunele and about 
four times longer than broad; its flagellum is three and a half 
times longer than the branch and slightly longer than the breadth 
of the head. The lower branch is about two thirds as long as the 
upper one and twice as long as broad, with the anterior distal 
angle very deeply and: obliquely cut off; its posterior flagellum is 
one fifth shorter than the flagellum of the upper branch and almost 
"twice as long as thé anterior one: All three flagella are robust 
and distally consideråbly thickened. The globulus is moderately 
small, a little legs broad than the upper branch; its stalk is very 
short. 
Trunk (fig. 15). Moderately slender. — The fifth pair of. 
tactile setæ (preserved in a single specimen) is very long, nearly 
two and a half times longer than the breadth of the segment, be- 
sides these setæ are unusually robust and their pubescence much 
longer and more stiff than in any other species. The fourth pair 
of tactile setæ is slightly more than half as long as the fifth, 
rather thin and with the pubescence well developed; the third pair 
about one fourth shorter than the fourth, slightly thickened from 
the base to the middle and from thence tapering, besides more densely 
pubescent than the fourth pair. — The dorsal setæ on the penul- 
timate segment long; the setæ on the last segment tapering, very 
long, the longest of them half as long as the distance between the 
tactile setæ.
