56 NEW NOKTH AMERICAN MELANOPLI (ORTHOPTERA) 



male cerci are shorter with distal portion proportionately much 

 broader and distal margin rounding strongly to the less produced 

 ventro-caudal angle, while the male subgenital plate is shorter 

 and not as sharply conical (for huachucana see plate III, figures 

 4 and 5). 



In the coloration of the caudal femora, coyoterae agrees more 

 closely with C. miguelitana (Scudder), in all other respects being, 

 however, the opposite extreme of the forms of this stock, 

 huachucana occupying an intermediate position in the form of 

 the male cerci. 



Type. — c? ; Prescott, Arizona. Elevation, 5400 feet. July 21, 

 1917. (J. A. Kusche.) [Hebard Collection, Type no. 751.] 



Size rather large compared with species of allied genera; form robust, sub- 

 fusiform. Head as in huachucana 8 , small in proportion to the body bulk, 

 distinctly narrower than greatest pronotal width, scutellum of the fastigium 

 weakly concave between the very delicate but distinct lateral carinae, frontal 

 costa weakly concave toward the median ocellus, eye distinctly over one and 

 one-half times as long as infra-ocular sulcus. Pronotum, tegmina and abdomen 

 as in huachucana. Furcula represented by thickenings of the tergite, caus- 

 ing weak and well separated angulations of the margin. Supra-anal plate 

 triangular with apex blunted, nearly as long as wide, msdian sulcus broad 

 and percurrent, deepest in proximal half, lateral portions weakly and broadly 

 concave, with a minute conical projection near the lateral margins at two- 

 fifths the distance to the apex. 9 



Cercus narrowing in proximal third, thence widening greatly, due to ex- 

 pansion dorsad, the ventral margin being broadly and evenly convex through- 

 out, the dorsal portion of the expanded section (which is nearly twice as wide 

 as the proximal width and nearly half as wide as the cereal length) convex to 

 the acute-angulate, briefly produced ventro-caudal angle (the apex). Sub- 

 genital plate conical, its apex blunt, shorter and blunter than in huachucana. 

 Cephalic and median femora somewhat inflated and weakly bowed. 



Allotype. — 9 ; Prescott, Arizona. Elevation, 5400 feet. July 

 31, 1917. (O. C. Poling.) [Hebard Collection.] 



Very similar to females of huachucana, except that the caudal femora are 

 not contrastingly colored, the external pagina of the general brown coloration, 

 feebly and not solidly suffused with a darker shade. 



Differs from the male in the following features. Size decidedly larger, form 

 much more robust. Eye less than one and one-half times as long as infra- 

 ocular sulcus. Even widening of the pronotal disk as regular but decidedly 

 stronger. Ovipositor valves with stout apices moderately elongate and weakly 

 curved, blunt teeth of dorso-external margin of dorsal valves large and irreg- 

 ular. Cephalic and median femora not inflated; the former nearly straight, 

 the latter straight.

 1907, p. 48, (1907). 



9 Also found in huachucana.
