Size small: form markedly depressed: surface of pronotum and tegmina dull 
and minutely shagreenous, of remainder of body moderately polished but fre- 
quently with a very weak shagreen. Head with its width visible cephalad of 
the pronotum, the occiput greatly flattened, the general outline of the head 
trigonal when seen in cephalic aspect: occiput rounding regularly over the 
vertex into the face: interspace between the eyes very' broad, slightly greater 
than that between the irmer margins of the antennal scrobes, the interocular 
region ventrad to the interantennal region with spaced, distinct, stellate im- 
pressions, from which spring single chaetiform hairs; region of the antennal 
scrobes marked off from the vertex by arcuate, converging and ventrad van- 
ishing angles: clypeus and labrum strongly transverse: palpi with third joint 
rather slender, straight; fourth joint distinctly shorter than the third, 
funnel-shaped; fifth joint subequal to the third, of the typical Blattid form, 
the greatest width at the proximal third: eyes strongly depressed, elongate 
reniform in outline: antennae very slightly longer than the body, multiarticu- 
late, the articles moniliform, very short proximad, increasing in length distad, 
the distal joints very shghtly longer than broad; proximal joint thickened, 
second and third joints larger than fourth and succeeding; from fourth joint 
distad the antennae are adpressed hirsute. Pronotum faintly transverse, 
roughly quadrate in form, greatest width at caudal fourth: cephalic margin 
regularly arcuate, rounding into the weakly oblique, gently diverging and 
slightly arcuate lateral margins; caudo-Iateral angles rounded obtuse; caudal 
margin very slightly arcuate : surface of disk with complicated less shagreenous 
pattern: lateral portions of pronotum narrow, flattened, translucent, the disk 
sharply and narrowly rounding ventrad to the level of the lateral portions. 
Tegmina lanceolate, the greatest width contained nearly two and one-half 
times in the greatest length of the same, and situated at three-fifths of the 
length from the base; coriaceous, the marginal field mottled translucent, the 
portion of the dextral tegmen normally covered when the tegmina are closed, 
shining, but with a distinct and rather modified venation : costal margin faintly 
arcuate proximad, thence obliquely straight to the point of greatest width, 
which is broadly rounded and from where the margin is obliquely arcuato- 
truncate to the rounded rectangulate apex, which is faintly sutural in position; 
sutural margin very faintly arcuate, strongly rounded proximad to the base, 
rounding in similar fashion distad to the apex : marginal field relatively narrow, 
attenuate, reaching to the point of greatest width of the tegmen, flattened and
