62 NEW NORTH AMERICAN MBLANOPLI (oRTHOPTERa) 



Furcula re])rcsent.ed by two minute projections, with bases weaky convex 

 to base of their tcrgite, the projecting portions shghtly longer than wide. 

 Supra-anal plate shield-shaped, with lateral margins proximad straight and 

 parallel for a short distance, then moderatc^ly raised, very weakly concave and 

 convergent to the short, thick, weakly elevated disto-lateral carinae, the small 

 apical portion triangular with apex bluntly rounded. Surface of sui)ra-anal 

 l)late broadly concave laterad, with a broad medio-longitudinal sulcus in 

 proximal half, which is very weak (absent in paratype) in distal half. 



Cerci nearly two and one-half times as long as basal width, straight, narrow- 

 ing gradually, then expanding, so that the distal third is slightly enlarged with 

 dorsal margin slightly more convex than ventral margin, apical portion with 

 external siu'face weakly concave, broadly rounded dorso-distad, but forming 

 a moderately (sharply, in paratype) rounded rectangulate disto-ventral angle, 

 the distal margin transverse. Subgenital plate j^roduced meso-dorsad in a 

 large, bluntly rounded tubercle, directed caudad, which tubercle is slightly 

 more i:)roduced and less heavy than in fcniur-tiigriuii. 



Allotype.- — 9; same data as type. [Acad. Nat. Sci. Phila.] 



Agrees with type except as follows. Size larger, form more robust. Sul- 

 cation of vertex and frontal costa weaker and broader. Eye about one and 

 two-thirds times as long as infra-ocular sulcus. Pronotum with lateral 

 margins of disk weakly divergent to principal sulcus. Prosternal spine heavier 

 toward its base. Ovipositor valves moderately elongate, with distal curvature 

 rather broad; the dorsal valves with dorsal surface and margins proximad 

 rather well sup])licd with serrations.

Dorsal suifacie of male blackish chcstinit-brown; the lateral margins of (lie 

 pronotal disk outlined in buffy to the principal sulcus in the paratype (a 

 frequent color feature in si)eci(>s of this grouj)). Oth(>r portions of head, 

 vi'utral portions of i)ronotal lateral lobes, cephalic and median limbs and under- 

 parts clay color, often with an oliva(aH)us ting(>; the head with a broad shining 

 postocular l)Iack bar, which broadens and is continued on the lateral lobes of 

 the principal sulcus. Lateral portions of thorax blackish, witli a striking, 

 obli(|ue bar of light, buff. Sides of abilonuMi heavily ov(>rlaid with shining 

 bhick, (his narrowing sdongly caudad.
