MORGAN HEBARD 373 



rounded apices reaching as far as the bases of the apices of the 

 proximal processes opposite the termination of the incurled lateral 

 portions of those processes. Subgenital plate convex with a 

 prominent apical tubercle. 



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



Considerably larger and more robust than male. Pronotum 

 with medio-longitudinal carina (usually) almost as decided on 

 prozona as on metazona. Prosternal spine broader proximad 

 but with sharply rounded apex. Tegmina broader (sometimes 

 almost circular), separated by a decided (to very decided) inter- 

 val. Ovipositor valves moderately elongate, apices well curved, 

 dorsal pair with dorso-external margins irregularly and not de- 

 cidedly toothed but dorsal surfaces in proximal portion with a 

 number of very irregular and broken rows of teeth. 



The extremes in the series measure as follows: length of body 

 cf 16. to 17.5, 9 20. to 21.; length of pronotum c? 4.2 to 5.1, 

 9 5.3 to 5.8; caudal width of pronotal disk d" 2.7 to 3., 9 3.9 to 

 4.1; length of tegmen cF 3.2 to 4, 9 2.4 to 4.1; length of caudal 

 femur & 10.1 to 11.1, 9 11.1 to 11.6 mm. 



The apex of the abdomen is curled upward in males and the 

 length here given is taken with this in normal position, not 

 straightened out. 



Generally dark chocolate brown, postocular bar very broad, 

 percurrent on pronotal lateral lobes, rarely flanked dorsad nar- 

 rowly with dull buffy. Face, genae and ventral portions of lateral 

 lobes buffy washed with reddish brown or dull olivaceous. 

 Oblique streak on pleura very conspicuous, clear buff. Dorsum 

 of abdomen often paler and more reddish brown than elsewhere. 

 Cephalic and median limbs buffy, often heavily suffused with dull 

 olivaceous. Caudal femora dorsad usually suffused and dark, 

 sometimes buffy with two weakly indicated transverse bands on 

 inner portions only, external pagina solid shining deep chocolate 

 very narrowly margined dorsad (this widest proximad) with 

 buffy and with a broad, very conspicuous, longitudinal ventral 

 marginal band of cream color; ventral surfaces vandyke red with 

 base and a pre-genicular annulus of buffy, genicular areas very 

 dark brown paling only on the lobes. Caudal tibiae deep pink, 

 paler on sides, with a post-proximal brown fleck. 



A series of twelve male and five female paratypes was taken 

 with the type from 9800 to 9900 feet on the north slopes of the 

 Magdalena Mountains in grass under Aspen, Poplus tremuloides, 

 saplings.
