of legs — and these four specimens are rather well or well 
preserved. 
Head (fig. 6 a). The eyes are large, two and a third times 
longer than broad, and the distance between them is scarcely three 
fourths of their length. — All the hairs are ringed and the an- 
terior ones slightly clavate; those in the two anterior rows and the 
submedian pair in the fourth row are moderately short; the hairs 
im the third row are unusually long, the outer pair, which is some- 
what longer than the inner, being about half as long as the long 
eyes. The intermediate pair in the fourth row is proportionately 
rather short, being about as long as the inner pair in the third 
row, while the sublateral pair is much longer, about two thirds as 
long as the eyes. 
Antennæ (fig. 6 a). Of the two front hairs on the fourth joint 
the upper one is as long as the two distal joints together and more 
than twice as long as the other. The upper branch is searcely 
three times longer than broad and slightly as long as the two di- 
stal joints of the peduncle; the flagellum is more than four times 
longer than the branch, but somewhat shorter than the breadth of 
the head. The lower branch is scarcely three fourths as long as 
the upper one, about one half longer than broad, strongly widening 
from the base outwards, and the anterior angle is very deeply and 
obliquely cut off. The posterior flagellum is somewhat shorter than 
that on the upper branch and sa little more than twice as long as the 
anterior flagellum. All three flagella and especially that on the 
upper branch are rather robust and strongly thickened distally. The 
globulus is large, slightly oblong, about as thick as the upper 
branch; the stalk is somewhat shorter than the transverse diameter 
of the globulus. 
Trunk (fig. 1 a). Moderately robust. — The fifth pair of 
tactile setæ is short, only a little longer than the breadth of the 
segment, 'thin and with the pubescence very faint; the fourth pair 
is slightly more than two thirds as long "as the fifth and very thin. 
The third pair is slightly shorter than the fourth, gradually some-
