Maxillae . — Convergent; extend beyond lip about three 
tenths of their length; palp inserted into basal third. 
Lip . — About as wide as long. Sternal suture straight. 
Sternum. — Cordiform; moderately convex; only slightly 
longer than wide; widest between second coxae but nearly 
as wide between first coxae; with a moderately well devel- 
oped coat of long light colored bristles; posterior end a 
blunt point between fourth coxae which are separated by 
nearly 1.5 times their width. All coxae of moderate length, 
but first are somewhat the most robust. 
Legs. — 1243. Width of first patella at “knee” .0758 mm., 
tibial index of first leg 10. Width of fourth patella at “knee” 
.05956 mm., tibial index of fourth leg 11.

Each metatarsus bears a single long dorsal trichobothrium 
near the distal end of the segment ; each tibia bears a long 
dorsal trichobothrium near the middle of the segment; 
other less conspicuous trichobothria may be present but 
this is uncertain. The calamistrum is well developed on 
the fourth metatarsus where it extends over the proximal 
four fifths of the segment. 
Spines . — True spines seem to be completely lacking but 
bristles and spiniform hairs are numerous. 
Palp . — The retrolateral tibial apophysis is very long and 
it projects at a right angle. The tarsus is much flattened 
and bent sharply toward the ventral side in its distal third ; 
there is a long narrow cleft at its base and the basal hook 
is quite characteristically shaped. The cymbium is narrow 
and it projects beyond the embolus only a short distance; 
the embolus nearly encircles the structure (Fig. 1).
