parallel proxiniad, the tegmen somewhat narrowed in distal half, 

 apex narrowly rounded; humeral and discoidal veins non-attingent. 

 throughout, discoidal vein with one distinct distal ramus, mediart 

 vein diverging slightly proxiniad of the middle of the tegmina,. 

 biramose. Wings surpassing the tips of the tegmina by about two- 

 thirds of the dorsal length of the pronotum, apex of the closed wings 

 sutural and rectangulate, the costal margin arcuate to the apex. 

 Prosternum unarmed: meso-and meta-sternum strongly transverse,, 

 the former distinctly, the latter weakly emarginate mesad, caudo- 

 lateral angles of both plates strongly rounded. Supra-anal plate^* 

 moderately acute trigonal, surface plane: cerci simple, short, taper- 

 ing: ovipositor not strongly abbreviate and very deep as in olivaceus^ 

 but slightly bent at the base and faintly arcuate, the greatest depths 

 not more than one-half the length and the form narrowed distad;. 

 dorsal margin of the ovipositor very faintly arcuate-concave, the- 

 extremity of the dorsal valves narrowly rounded; ventral margin of 

 the ovipositor strongly arcuate throughout; all of the margins ex- 

 cepting the proximal third of the ventral margin with strong spini- 

 form teeth, which are directed disto-dorsad on the dorsal margin! 

 and appreciably recurved on the ventral margin, those distad on 

 the latter strongly recurved ; surface of the ovipositor with three lines. 

 of serrato-dentations and mesad irregularly scattered, low, rounded 

 tubercles: subgenital plate acute trigonal, compressed. Cephalic- 

 and median femora unarmed beneath; cephalic tibiae sulcate dorsad, 

 but margins without spines excepting the caudal apical one; fora- 

 mina open. Caudal femora four-fifths as long as the tegmina,. 

 strongly inflated proxiniad, distal half slender and the ventral mar- 

 gins there with not more than three spines, genicular lobes bispinose. 

 General color (apparently that of life) cinnamon, the tegmina 

 with their base color warm fuscous, the venation and reticulations 

 outhned in the general color proximad and in maroon distad; tibiae 

 and the distal half of caudal femora washed with ox-blood red, the 

 distal extremity of the caudal tibiae and the tarsi fuscous. Eyes, 

 brussels brown; antennae (aside from the proximal joint which is of 

 the general color) amber-brown, multi -annulate with fuscous, which 

 is the predominating color distad; face with the ventral margin of 

 the antennal scrobes, the clypeal suture and a pair of short, arcuate 

 vertical lines on the dorsal half, fuscous. Tegmina faintly greenshi 



'^ This is not clearly sepai'ated from the disto-dorsal abdominal segment, sa 

 the term is used in an analogous, not a strictly homologous, sense.
