the bottom of the emarginatioii shKhth' truncated: supra-anal plate moderately 

 transverse, shield-shaped, apex very narrowly acuminate: cerci complex, with 

 a moderately inflated, semi-bull)ous base, which bears numerous long hairs 

 placed in sensory pits or craters, this portion short and narrowing regularh^; 

 distal section shining, consisting of two parts, one an outer, compressed, 

 lamellate, arcuate, obtuse-angulate (in profile) section, this tapering in width 

 and ending in an acute spine; the other an inner, compressed, elongate, lamel- 

 late portion, which is bifid, the extreme tip unguiculate, terminating in a 

 spine, the liranch placed ventrad of the main extremity, recurved, slightly 

 curled and armed with four marginal denticulations; the two arms of the distal 

 section of the cercus in contact and apparently immovably so: subgenital 

 l)Iate longitudinal, narrow in proximal two-thirds, slightly widening in distal 

 third, distal margin nearly semicircularly arcuate-emarginate, ventral surface 

 of plate with a low, medio-longitudinal carina and thickened lateral rods, 

 which form the foundations for the attachment of the short, simple, but 

 articulate, styles. 



Limbs with surface carinate and substrumose. Cephalic femora short, the 

 dorso-cephalic face with four low, but distinct, rugulose strumosities, of which 

 the two proximal extend to the ventral margin of the femur; ventro-cephalic 

 margin with two spines distad, which are distinctly inflated proximad; ventro- 

 cautlal margin unarmed; genicular lobes spined: cephalic tibiae appreciably 

 longer than the femora, with the tympani exposed, large; dorso-cephalic margin 

 with several distinct tubercles. Median femora slightly longer than the 

 cephalic femora; ventro-cephalic margin with three lamellate spines, the distal 

 the larger; ventro-caudal margin unarmed; genicular lobes spiniferous; cephalic 

 face with three groups of low, rugulose strumosities: median tibiae distinctl}' 

 longer than the femora, ventral margins distinctly spined, dorsal margins with 

 three pairs of recurved spiniform lobes, and in addition two extra similar ones 

 on the dorso-caudal margin. Caudal femora about two and one-fourth times 

 as long as the tegmina, slender, subcompres.sed, rugulose; ventro-external 

 margin with four lamellate spines, the distal much larger than the others and 

 truly lamellate; internal margin with three spines, the distal relatively large 

 and sublamellate, but distinctly smaller than the external one, the other two 

 spines minute; genicular lobes spiniferous: caudal tibiae distinctly surpassing 

 the femora in length, dorso-external margin with thirteen to fourteen spines 

 of similar character of variable size; ventral margins with nine to ten pairs of 

 sliort, addressed spines. 



General body color bister, touched and jiointed with fuscous, and also 

 russety on the occiput and dorsum of the pronotum, the limbs mottled and 

 brokenly annulate with dull antimony yellow, which is often further contrasted 

 by blackish fuscous pencillings. Eyes saccardo's umber; antennae numerously 

 but obscurely annulate russet and yellowish, the nodes darkened and with the 

 bristles on them blackish fuscous. Abdomen with its dorsal surface much 

 darkened with fuscous, the median lobules russety, spine-like portion of cerci 

 black-tijjped, styles greenish. Annulate type of coloration apparent only on 

 the median and caudal femora, and there the pale color is between the stru- 

 mosities, which are much pencilleil with l)lacki.';h fuscous. Tegmina of a
