femora with ventro-external margin armed with none to one (in the series 

 none to two) spines; ventro-internal margin armed with six to seven (in the 

 series five to ten) spines. Cephalic genicular lobes of cejihalic femora and 

 genicular lobes of median femora armed with two short spines (occasionally 

 one in the series). Caudal genicular lobes of cephalic femora unarmed (in 

 the series rarely with one or two small, short spines). Genicular lobes of 

 caudal femora unarmed. Cephalic femora with dorsal surface armed along 

 the caudal margin with three spines, cephalic margin unarmed. Caudal tibia 

 armed with three pairs of distal spurs, of which the medio-internal is the long- 

 est, as long as the full length of the metatarsus, the medio-external three- 

 quarters as long as the medio-internal, the dorsal pair each slightly over half 

 as long as the medio-external. Plantula over half as long as the full length 

 of the metatarsus. 



Allotype. — 9 ; same data as type. [Hebard Collection.] 



Agrees closely with male, differing in the following features. Size larger. 

 Tegmina apparently not developed. Penultimate tergite produced meso- 

 caudad in two small rounded projections, between which and above the small 

 rounded supra-anal plate this tergite is rotundato- emarginate in an area deep- 

 er than broad. Cerci simple, straight, elongate conical. Ovipositor com- 

 paratively short, slightly over half as long as caudal femur, moderately and 

 evenly upcurved, with acute apex at juncture of valves, the distal portion 

 and margins polished, each valve distad medio-longitudinally and also along 

 its free margin delicately carinate. Subgenital plate boxing base of ovipos- 

 itor, with free margin intnu'ved so that the plate appears angulate-emargi- 

 nate mesad. 



Sexes similar in coloration. Surface shining. Base coloration cinnamon- 

 buff. Face and vertex cinnamon-buff, cheeks tinged with slate, dorsal sur- 

 face of head sepia. Pronotum sepia, narrowly margined cephalad and broad- 

 ly along ventral margins of lateral lobes with cinnamon-butf, caudal margin 

 of disk narrowly blackish, this broadening on each side and filling the distal 

 portion of the produced section of the lateral lobes. None of these markings 

 with margin sharply defined. Underparts and limbs cinnamon-buff, the 

 caudal femora broadly tipped with blackish brown. Exjiosed metanotum 

 (tiiuiamon-buff, median segment suffused with sejiia in distal portion, with 

 (uiudal margin very narrowly blackish chestnut. Tergites to penultimate 

 tergite cinnamon-buff, heavily tinged with sepia, particularly dorsad on each 

 side, with caudal margin of each very narrowly blackish chestmit. Pen- 

 idtimate tergite cinnamon-buff heavily tinged with sepia. 



In the individuals of intensive coloration the occiput, major portion of tlie 

 pronotum and sliglitly broader caudal margms of the tergites are very dark, 

 mummy brown. In two specimens of recessive coloration the occiput and 

 and pronotum are bucikthorn brown washed laterad with olive lake, the 

 (!au(lal margin of the pronotum very narrowly blackish and the other dark 

 areas correspondingly i)aler, ex(H^i)t the caudMl margins of the tergites, 

 which are as (iontrastingly darker as in the more usual condition.
