specimens, only the anal plate region and the spiracular areas 
retaining any marked color; antennae reduced to short stubs, 
very indistinctly 4-segmented, bearing a few short slender 
setae and several stout blunted setae at apex; legs also greatly 
reduced, the different parts not distinguishable, claw present, 
the claw digitules present, threadlike, curved, extending slightly 
beyond the apex of the claw; spiracular grooves distinctly 
deeper than in quinquepori , the heavy collar at the inner end 
perhaps one-third to one-half as wide as in that species and the 
spiracle itself placed almost immediately below and just inside 
of the collar rather than at the inner end of a distinct mem- 
branous tube as in quinquepori ; no spiracular spines observed; 
marginal setae stout, spinelike, tapering, with swollen bases and 
acutely pointed tips; beak small and short, apparently 1- 
segmented; clorsally with an occasional relatively large, circular, 
apparently very faintly multilocular, disk pore, with much more 
numerous, smaller circular pores with bilocular centers, scattered 
uniformly over the surface, and with considerably smaller, 
simple pores, probably in the aggregate more numerous than 
the second sort, but tending to cluster into groups of four or 
more, with wide intervals between clusters; ventrally with 
multilocular disk pores beneath and around in at least three 
distinct arches anterior to the anal plates, these normally with 
eight loculi and somehwat larger than the largest dorsal pore, 
and with much smaller, apparently simple, circular pores with 
oval centers, these arranged irregularly in distinctly segmental 
bands across the middle portion of the abdominal segments, 
but more numerous and less definitely arranged towards the 
body margin; no dorsal setae observed except at body margin 
and a scattered cluster just inside the opening of each spiracular 
collar; ventral setae present, not especially numerous or cons- 
picuous, scattered, except for some indefinite segmental rows 
anterior to the anal plates, and most abundant on that portion 
of the ventral surface behind the posterior spiracles; no sub- 
marginal tubercles, such as may be found in some genera in this 
subfamily; the “submarginal compound pores” of quinquepori 
not in evidence; anal plates surrounded b}'- a heavily chitinized
