MORGAN HEBARD 181 



a few of the specimens from other parts of its range are colored 

 the same as in payettei. 



Type. — $ ; McCall, Big Payette Lake, Idaho. Elevation 

 5000 feet. August 11, 1910. (M. Hebard). [Hebard Collection, 

 Type No. 1266]. 



Generally similar to large individuals of indigens except as noted above. 

 Vertex very slightly more produced than is normal in that species, it and 

 the frontal costa as here described for indigens missoulae. Pronotal disk 

 with fine medio-longitudinal carina on metazona, still finer but distinct on 

 prozona. Prosternal spine moderately elongate, rather slender, tapering 

 evenly to the rather sharply rounded apex. Tegmina ovate, lateral margins 

 in distal half convergent to the rounded apices, separated by a very narrow 

 interspace, length very definitely less than that of pronotum. Apex of 

 ablomen moderately thickened. Furcula a pair of small, slender, very 

 strongly divergent projections, over twice as long as width from beyond 

 the thickened areas from which they spring. Supra-anal plate shield- 

 shaped, median and lateral portions longitudinally concave, transverse 

 carina absent (but indicated in one paratype), lateral margins thickened in 

 proximal portion but only slightly more so (or not at all) opposite cereal 

 bases. Cercus proportionately distinctly smaller than in indigens, length 

 slightly over twice proximal width, nearly straight but directed slightly 

 dorsad of caudad; dorsal margin declivent proximad, then subparallel to 

 ventral margin, distad rounding into the convex apex slightly more broadly 

 than does the ventral margin; distal portion as broad as *the median, its 

 entire surface feebly impressed. Penis with dorsal lobes developed into 

 two very large, erect, transverse, adjacent, fleshy plates (see plate XII, figure 

 10), one minute aciculate pair of parameres visible meso-proximad. Sub- 

 genital plate with apex scarcely produced, very weakly and bluntly 

 binodose. 



Allotype. — 2 ; same data as type. [Hebard Collection]. 



Differs from male as does this sex of indigens missoulae, described on 

 page . Tegmina similar to those of male (but in some paratypes pro- 

 portionately smaller, more nearly oval and slightly more widely separated). 



The measurements for the extremes in the series (all from McCall except 

 the smallest female, from Evergreen) are: length of body S 20. to 21., 

 $ 23.8 to 272; length of pronotum $ 4.7 to 4.9, 2 5.4 to 6.; caudal width 

 of pronotal disk $ 2.6 to 2.7, $ 3.7 to 3.8; length of tegmen $ 4.4 to 3.8, 

 $ 4.7 to 5.4; length of caudal femur $ 11. to 11.5, $ 13.8 to 14.2 mm. 



Coloration much as in indigens missoulae as described on page 175, 

 except as follows. In the present small series little intensification and no 

 recession is shown. Caudal femora sometimes appearing gray brown with 

 darker oblique suffusions (instead of dark with paler areas as is sometimes
