Legs not unusual for the genus, tibia and tarsus approxi- 
mately equal in length; spiracles slender and somewhat cylin- 
drical in middle, broadly expanded at each end; marginal setse 
numerous, long, slender, bluntly pointed at apices, spaced ir- 
regularly, but averaging about their own length apart, averag- 
ing about 32 jx in length, posterior spines longer, those on each 
side of the apex of anal cleft as much as 100 /* long; spiracular 
spines in groups of three, the middle a little more than twice 
the length of either of the other two, the latter often slightly 
unequal in length, all stout, the smaller tapering uniformly to a 
rounded apex, the larger tapering distinctly only near the apex ; 
dorsally with some widely scattered tiny peglike tapering spines, 
apparently arranged in curving longitudinal rows ; ventrally with 
a submarginal row of tiny setse and with a few others, similar, 
scattered over the under surface of the body, with three pairs 
of long, slender setse just anterior to the anal lobes and another 
pair, unequal in length, inside each antennal base ; dorsally with 
an abundant supply of minute, short-tubular gland ducts, each 
with a slender, threadlike continuation of the bottom, with a clus- 
ter of circular disks, presumably glandular, anterior to the anal 
plates, and with a median cluster of bilocular and circular pores 
nearly opposite or a little behind the middle legs ; ventrally with 
a single to triple line of circular quinquelocular pores between 
the spiracles and the corresponding spine groups, and with 
larger multilocular pores, with nine or ten loculi and large 
open centers, in a cluster around the anal plates; submarginal 
gland tubercles very numerous, varying from forty-two to forty- 
eight in the specimens examined, often with an uneven number 
on each body half, and sometimes with two, one within the 
other, at the same point on the margin; anal plates in normal 
position, the cleft short, triangular, nearly twice as long as wide, 
the posterolateral face distinctly longer than the anterolateral, 
under compression appearing proportionately broader, with the
