64 NEW NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



spine is more slender with apex much more sharply rounded in the paratypes) . 

 Tegmina considerably shorter than pronotum, almost attingent, with apex 

 broadly rounded. 



Fuxcula represented by a pair of minute, slender processes, three times as 

 long as broad, which do not taper to their rounded apices (varying to more 

 slender and weakly tapering in the paratypes), are faintly divergent (varying 

 to moderately divergent in the paratypes), with length contained in that of 

 supra-anal plate nearly four times (varying to three and one-half times in the 

 paratypes). Supra-anal plate moderately elongate, shield-shaped; median 

 sulcus decided, with lateral margins distinctly carinate to slightly beyond 

 median point; transverse carina there, toward the lateral margins of this 

 sulcus, developed into a small but conspicuous lamella on each side, with margin 

 rounded; lateral portions of plate rather strongly concave, disto-lateral carinae 

 subobsolete. 



Cerci f aintly bent slightly beyond end of proximal two-thirds, approximately 

 twice as long as basal width, tapering strongly proximad; dorsal margin broad- 

 ly concave, ventral margin straight, becoming weakly convex distad; distal 

 portion very slender to the rather sharply rounded apex, the external surface 

 showing faint subapical concavity. Subgenitalplate with median section of 

 equal depth laterad and mesad, curving and tapering meso-distad to the blunt 

 apex, which shows no trace of tuberculation. Limbs as in sonomaensis. 



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



Size larger, form heavier, fastigium of vertex broader and less deeply sulcate 

 than in male. Compared with females of sonomaensis above.
