space between mesosternal lobes of male twice or nearly twice as 

 long again as broad; cerci not finely acuminate at tip. 



fuscipes McNeill 

 cA Tegmina attingent; interspace between mesosternal lobes of 

 male only slightly longer than broad; cerci tapering, rather regular, 



subfalcate, finely acuminate at tip scituhis Scudd. 



fi. Hind tibia; red; male cerci very simple and straight, hardly in- 

 curved. 



d'^. Slender forms. Male cerci equal and very slender in distal 

 third or more, about one-third as broad as the extreme base. 



islandicus Blatchl. 

 di. Stouter forms. Male cerci very stout and broad, tapering 

 throughout apical half and very bluntly rounded at apex. 



truncatus sp. nov. 

 U^. Tegmina longer than the pronotum, elongate, overlapping or attin- 

 gent, apically acuminate. 



<:'. Slender forms. Pronotum feebly angulate behind, the median 

 carina percurrent, subequal; tegmina attingent, in one plane, no longer 

 or scarcely longer than the pronotum; hind tibiae green; interspace be- 

 tween mesosternal lobes of male twice as long as broad. 



phcetaliotiforniis sp. nov. 

 c^. Stouter forms. Pronotum distinctly angulate behind, the median 

 carina subobsolete between the sulci; tegmina overlapping, in two 

 planes, one represented by the anal area, the other by the remainder, 

 fully as long as, generally much longer than, the pronotum; interspace 

 between mesosternal lobes of male quadrate or subquadrate. 



d'^. Male pronotum scarcely expanded on the metazona; tegmina 

 but little longer than the pronotum; apical half of male cerci very 

 slender, slenderer than the antenna; incultus sp. nov. 



^2. Male pronotum considerably expanded on the metazona; teg- 

 mina fully half as long again as the pronotum; apical half of male 

 cerci relatively stout, as large as the antennae hiironi Blatchl.

 Plate VII., iMgure 7. 



Rather small, the female often considerably the larger, testaceous 

 much marked with fuscous, dull flavous beneath. Head slightly 

 prominent, at least in the male, fiavo-testaceous, much and delicately 

 mottled with pale fuscous, or above with darker fuscous, with a dark 

 fuscous postocular stripe; vertex gently convex, faintly elevated 

 above the pronotum, the interspace between the eyes as broad (cf ) or 

 nearly twice as broad (?) as the first antennal joint ; fastigium steeply
