the second, from this joint the succeeding articles regularl}" increase 

 in length distad. Pronotum as broad as long; cephalic margin 

 truncate, lateral and caudal margins and caudo-lateral angles arcuate, 

 cephalo-lateral angles slightly obtuse; transverse median depressed 

 area slight, lateral regions with slight longitudinal depressions, longi- 

 tudinal median sulcus present, slight, very faint caudad. Tegmina 

 slightly more than twice the length of the pronotum, moderately 

 expanded, "shoulder" angles rather narrowly rounded; caudal mar- 

 gin of each tegmen arcuato-emarginate. Exposed portions of the 

 wings nearly half as long as the tegmina, rounded on the distal half. 

 Abdomen slightly inflated mesad, the segments armed laterad, and 

 the distal one (excluding anal segment) dorsad with marginal series 

 of bead-like prominences, two proximal seg- 

 ments with lateral plicse; anal segment slightl}' 

 broader than long, slightly constricted caudad, 

 caudal margin slightly produced, thickened, 

 truncate between the centers of the arms of 

 the forceps; subgenital plate transverse, caudal 

 margin l)roadly arcuate; pygidium subcunei- 

 form, constricted mesad, the base trigonal. 

 Forceps equal to the pronotum, tegmina and 

 exposed portions of the wings in length, mod- 

 erately depressed, expanded at the base with 

 a short internal lamellate ridge, which bears 

 a distinct distal tooth and crenulations on the 

 remainder of the edge; arms subparallel, very 

 slightly caudad of the middle, tips evenly 

 curved mesad, acute, crossed; internal surface 

 of the aruis without a distinct ridge and 

 unarmed. Limbs of moderate size, cephalic 

 femora slightly inflated; tarsi strongly depressed, the second joint 

 distinct cordiform and extending considerably beneath the third joint; 

 arolia absent. 



General color of the head, pronotum, tegmina and exposed portions 

 of the wings bufl", rather diluted and weak on the head and pronotum; 

 eyes blackish-brown; antennas slightly obscured distad; tegmina with 

 all the margins except the caudal lined with seal brown, the lateral 

 margins very broadly marked; exposed portions of the wings buff 

 margined laterad with seal brown, the bar narrowing and becoming 

 evanescent caudad. General color of abdomen tawn3'-olivo, more red- 

 dish, the ventrad margins of the segments broadly marked with black- 

 ish laterad; anal segment ferruginous, margined caudad with blackish; 

 pygidium ])lackish. Forceps rather pale ochraceous, becoming ferru- 

 ginous distad, the margins of the basal expansions blackish. Cephalic 

 limbs buff; median and caudal limbs tawny-olive, the median touched 

 with ferruginous.
