Distal portion of abdomen distinctly, though not decidcMlly, enlargod. Fur- 

 riila represented by two broad and well sei)arated, very brief eonvexities, 

 which extend very slightly beyond the margin of the tergite. Siipra-anal 

 plate with length about equal to width, broadly rotundato-triangular, latL'ral 

 portions broadly and weakly concave, with a minute node mesad; median 

 ])ortion weakly elevated and rather broadly and weakly concave. Cercus 

 over four times as long as its proximal width, bifurcate at end of i)roximal 

 three-fifths, i)roximal portion narrowest at its median point (where it is alwut 

 one-third as broad as long) due to the concavity of the tlorsal margin, ventral 

 margin straight throughout, except that feeble convexity is indicated proximad; 

 internal section of distal portion produced in a straight, flattened finger, sub- 

 (M|ual in width, about three times as long as broad, with greatest thickness 

 vertical and apex rounded, this finger directed meso-caudad; external section 

 of distal portion jjroduced in a straight slender spike, with apex very narrow- 

 ly rounded, longer than internal section and directed caudad, so that the axes 

 of these portions form an angle of something less than ninety degrees. 



Subgenital plate with depth about one-half length of the free margin, that 

 margin weakly concave laterad and feeblj' angulato-convex mesad. Pro- 

 sternal spine rather sharply conical, showing a weak flexure cephalad. Inter- 

 space between mesosternal lobes nearly twice as long as wide. Cephalic 

 and median femora heavy, inflated and bowed. Caudal femora rather short 

 and very robust, though proportionately not as short and robust as in Phaiil- 

 nkttix comprcssus. Caudal tibiae with eight to ten sj)ines. Caudal tarsus 

 distinctly less than half as long as caudal tibia. 



Allotype. — 9 ; same data as type. [Hel^ard Collection.] 

 .\grees closely with male in coloration and relative proportions; ditT(!ring 

 in the following features. Size larger, form moderately stouter. Vertex pro- 

 lK)rtionately slightly broader. Tegmina proportionately broader, attingent. 

 Genitalia normal, the ovipositor valves stout, with denticulations of dorsal 

 margin of dorsal pair blunt, heavy and irregular and with the stout apices acute 

 and well curved. Inters[)a(;e between mesosternal lobes about one and one- 

 lialf times as long as broad.
