nearly equal in width to length of prozona, regularly narrowing distad, reach- 

 ing practically to the tegminal apex. Wings relatively broad, greatest width 

 contained slightly less than twice in length. 



Mesosternal interspace strongly transverse, cephalic margin of interspace 

 very weakly obtuse-angiilate, internal angle of lobes rounded rectangulate, 

 caudal margin of lobes obliquely truncate : metasternal interspace not narrower 

 than mesosternal interspace, strongly transverse, shallow, cephalic margin 

 arcuate, lobes angulately converging caudad. Ovipositor jaw's moderately 

 compressed; dorsal valves moderately upcurved in distal third, ventral valves 

 gently arcuate decurved in distal half. 



Cephalic and median limbs of medium length, slender, the femora appreci- 

 ably enlarged distad. Caudal femora faintly more than two and one-half 

 times as long as dorsum of pronotum, moderatelj' robust for the genus, the 

 greatest depth contained slightly more than four times in greatest length; 

 dorsal carinae faintty sublamellate in proximal half; external paginal pattern 

 regular: caudal tibiae slightly shorter than femora, slightly sinuate proximad, 

 armed on external margin with eight, internal with ten to twelve spines: caudal 

 tarsi short, second and third joints together subequal in length to the proximal 

 joint. 



Allotype. — cf ; same data as t^-pe. [Hebard Collection.] 



Description of Allotype. — Differing from female sex in the following note- 

 worthy features. 



Size small: tegima more extensively subhyaline, a considerable portion of 

 distal half of such structure. 



Head with least width of interspace between eyes equal to three-fourths of 

 transverse width of eye: frontal costa with supra-antennal con.striction much 

 more decided than in female, there narrowly but distinctly and below broadly 

 but apprecialily sulcate: width of head' across genae three-fourths of width 

 across ej'es: eyes very prominent, slightly exserted, the depth slightly but 

 appreciably greater than that of infra-ocular portion of genae: antennae in 

 length subequal to caudal femora. 



Pronotum with surface smoother, less rugulose and more shagreenous than 

 in female: median carina slightly higher and more angulate in profile than in 

 female; tubercles caudad on prozonal disk more distinct and acute; lateral 

 carinae obsolete on metazonal shoulders: lateral lobes with metazona cribroso- 

 shagreeuous. 



Tegmina slightly less than three times as long as head and pronotum com- 

 bined. 



Mesosternal interspace with cephalic margin of interspace subtruncate: 

 metasternal interspace slightly narrower than mesosternal interspace. 



Caudal femora with greatest depth contained slightl}- less than four times 

 in length of same : caudal tibiae w-ith eight spines on external margin and ten 

 spines on internal margin.
