pubescent, testaceous apically, the two inner faces polished fer- 
ruginous, the margin between them with a very thin fringe of 
long pale hairs directed posteriorly; front tarsi moderately di- 
lated, pale yellow, the first joint very deeply hollowed out in 
front, the outer anterior margin with a short yellowish fringe, the 
inner one with a longer, more brownish fringe, the scale produced 
apically over the second joint, looking like the bow of a boat 
from without, the second joint narrowly produced apically, ex- 
tending slightly beyond the apex of joint 1, the third joint but 
very slightly dilated, the fourth not at all, fifth joint somewhat 
reddened apically, tarsal fringe white, rather yellowish within 
and tipped with fuscous or black, this evident at the edge of the 
fringe without; middle and hind legs entirely dark, the middle 
tarsi not much modified, with basal joint densely white pubescent 
exteriorly and with a long white hair fringe, middle tibiae with a 
bare impunctate area on outer face apically; hind tarsi rather 
peculiar, the basal joint short and thick, the following ones 
parallel-sided, hardly at all narrowed at base or widened apically, 
outer surface strongly convex, the inner surface flat; spurs pale 
testaceous; claws reddish testaceous basally, piceous apically, 
rather deeply cleft on the four anterior legs, not so deeply on the 
hind legs. 
Abdomen quite broad, pubescence pale ochraceous, with no 
black hairs, segments 2-5 with dense apical fasciae of somewhat 
more whitish pubescence, punctures fine and close on basal seg- 
ments, more sparse on the apical segments, which are shining; 
segment 6 shining, rugoso-punctate above the carina, neither 
emarginate nor produced medially, but the margin coarsely ir- 
regularly and rather sharply denticulate, a median rather deep 
concavity on the lower surface of the segment, rather coarsely 
rugoso-punctate on either side of this, the apical margin with 
two large teeth, one on either side of the middle, these widely 
separated, sublateral in position, close to the inconspicuous angles 
which represent the true lateral teeth; segment 7 large and cons- 
picuous, closely and finely punctured, rather evenly rounded, but 
the apex drawn out into a rather long slender spine; four ventral 
segments visible, these finely and closely punctured along their 
bases, the margins shining and impunctate, the fourth segment
