third, margins shagreeno-tuberculate, external face tuberculate mesad; 

 cephalic tibiae (exclusive of claw) three-fifths as long as the femur, armed on 

 the external face with seventeen short, rather depressed spines increasing in 

 length distad, on the internal face with thirteen distinctly longer, more arcu- 

 ate spines increasing in length distad, claw very long; cephalic tibiae subequal 

 to the tibiae; metatarsus comprising slightly more than one-half the tarsal 

 length. Median and caudal limbs simple, moderately slender. 

 Coloration completely destroyed by immersion in alcohol. 



Allotype. — cf ; Same data as the type. 



Size small; form elongate, moderately slender yet rather robust for the sex- 

 Characters here given supplementary to the type description. Head much 

 resembling that of the female sex but broader in proportion to the depth, the 

 latter being three-fourths of the greatest width, and in the line of the vertex 

 being but faintly arcuate; dorsal portion of face proportionately slightly 

 shorter than in female; ocelli large, paired ones subcircular, ventral one slightly 

 transverse elliptical in outline, elevated on a decided boss; facial scutellum of 

 the same general form as in the male but dorsal margin with the median angle 

 rectangulate and less sharply cut off from the lateral sections of the same mar- 

 gin; eyes with the internal margin more undulate than in the female. Pro- 

 notum similar in form to that of the female but caudal compressed section 

 slightly more elongate, margins unarmed, surface but sparsely and weakly 

 tuberculate; shaft non-carinate meso-caudad but with a transverse impression 

 cephalad of the caudal margin. Tegmina elongate, probably surpassing the 

 apex of the abdomen (this missing in the allotype), opaque in the marginal 

 field and vicinity of the humeral trunk, subhyaline elsewhere; costal margin 

 strongly arcuate proximad, very faintly concave thence to the broadly arcuate 

 section of the same margin, sutural margin gently arcuate throughout, oblique 

 subtruncate proximad, more strongly arcuate distad, apex rather narrowly 

 rounded; rami of the mediastine vein numerous, moderately regular, oblique, 

 discoidal field with transverse nervures generally sigmoid and often connected 

 by irregular false intercalated longitudinal nervures; stigma elongate, linear, 

 oblique, distad touching the humeral trunk. Wings reaching to the tegminal 

 tips. Abdomen largely missing. Cephalic limbs in general form similar to 

 those of the male; dorsal margin of coxae with a series of sparse, low, generally 

 uniform, weakly recurved dentiform spines, dorsal margin practicalh' unarmed, 

 external margin unarmed, internal face armed as in the female but more weakly 

 so, dorso-external face unarmed; cephalic femora slightly more than three 

 times as long as deep, teeth of the external margin shorter and more regular 

 in length than in the female; cephalic tibiae distinctly but not greatly exceed- 

 ing the length of the tibiae exclusive of the claw. Median and cuulal limbs 

 simple, moderately slender, very strongly hirsute.
