Tegniina nearly twice as long as pronotum, smooth, shining, hairless, truncate 
distad in full expanse of dorsal field. Wings concealed. Abdomen wdth 
dorsal surface polished, without hairs; sides in greater part parallel, carinae 
absent; disto-lateral portions of dorsal segments not produced, except of eighth 
segment which is broadly rounded; penultimate dorsal segment fully three times 
as wide as long, with distal margin smooth. Pygidium twice as long as mesal 
width, surface deplanate, nearly perpendicular in proximal third, there sharply 
cim’ed, deplanate and horizontal in distal two- 
thirds; lateral margins straight and feebly con- 
verging to distal fifth, becoming weakly cingu- 
late distad, straight, parallel, thickened and 
supplied with long, silky hairs in distal fifth; 
narrow distal margin roughly rectangulate-emar- 
ginate, with sides straight, disto-lateral angles 
sharply rounded. Forceps moderately hairy, 
with shaft showing external margin weakly con- 
vex, stout proximad with few, irregular dentic- 
ulations opposite pygidium and dorsal surface 
briefly deplanate beyond the slight basal en- 
largement, thence tapering evenly to mesal point 
where it is cylindrical, thence flattening with a 
feeble" flange developing internally and again 
gradually disappearing before the acute, weakly 
incurv'ed apex. Penultimate ventral abdominal 
segment with distal margin notched mesad, so 
that the distal portion of the pygidium is visi- 
ble from below. Limbs short, femora stout; first 
tarsal joint wdth ventral surface well supphed 
with hairs, in length equal to that of the minute 
second and elongate third joints combined.

Agrees with male except in the following features. Form more robust, the 
abdomen distinctly broader. Disto-dorsal abdominal segment more ample, 
surface triangularly w'eakly deplanate meso-distad, with caudal margin showing 
a series of well spaced, minute knobs, except on the brief lateral portions. 
Pygidium vertical, with surface deplanate, fitting tightly between the bases of 
the arms of the forceps. Forceps with numerous hairs dorso-proximad, very 
few minute, scattered hairs on other dorsal portions; shaft heavy, triquetrous, 
straight and evenly tapering to distal portion, where it is flattened, cylindrical, 
incurved to the .sharp, sudden apex; ventro-intemal margin, just beyond the 
base, produced in a moderate, percurrent flange, with its margin coarsely sub- 
serrate, in consequence the arms have their inner margins attingent throughout, 
except for a minute, triangular, proximal open space. Disto-ventral ab- 
dominal segment with distal margin obtuse-angulate but broadly rounded.
