68 Mr. R. V. Chamberlin on new 
these, the distal end free, triangular. Coxal plate of anterior 
gonopods in anterior view widening strongly, clavately distad ; 
distal edge oblique, incised a little mesad of ectal angle; the 
meso-distal angle a little prolonged, acute, tip a little curved ; 
from caudal surface below distal end arises a strongly 
curved distally acute process, which bears a blunt spur or 
lobe on caudal side near middle of length. Telopodite much 
shorter, broadest at base, which is curved mesad, the other. 
part lying against outer edge of and behind outer border of - 
coxa. Posterior gonopod emerges near middle of length 
of anterior coxa, which at this level bears a thick distally 
concave lobe, in the hollow of which rests the emerging 
posterior gonopod. 
The general colour of prozonites dark olive, the meta- 
zonites dark brown or somewhat ferruginous, the cauda and 
the elevated margins of anal valves the same. Autennze 
and legs yellow-brown or somewhat pale ferruginous. 
T'ransverse suleus across vertex very sharp; the longi- 
tudinal vertigial sulcus much finer, deeper at its lower end, 
which is ona level with the mesal angles of the eyes. 
Supra-labral region roughened by numerous vertical rugee. 
Frontal region smooth. QOcelli in seven transverse, curving 
series. Antenne short, reaching but little beyond the 
collum. Cardo of mandibles in male strongly produced at 
the ventro-caudal angle. Stripes of gnatho-chilarium (male) 
at distal end with a large rounded thickening; proximally 
with numerous short spinules. 
Collum strongly narrowed on each side, narrowest a little 
above lower end, the anterior corner being somewhat 
extended, narrowly rounded; the caudal corner also rounded ; 
lower margin a little convex. Elevated border very broad 
about antero lateral corner. No sulci excepting the mar- 
gining one on each side, the surface elsewhere being smooth 
and shining. 
Transverse sulcus of segments very deep throughout, 
widely curving opposite the pore, which is well removed 
from it. 
Anal valves densely finely punctate above; compressed 
mesally, the mesal border strongly elevated, but without 
definite margining furrow. Gauda short, acuminate, a little 
upcurled. 
Number of segments fifty-five. 
Width (male) 8°1 mm.
