NO. 1453. SOUTH AMERICAN (IRAHSJIOPPERS—REHN. 889 



tigium rounded rectangulate, slightly impressed in the form of a cres- 

 cent, interspace between the eyes slightly more than half again as 

 broad as the dorsal width of the frontal costa; lateral foveola? rather 

 weak, punctate; angle of the fastigium and the frontal costa nar- 

 rowh' rounded, the face roundly and moderately i-etreating; frontal 

 costa tumid, strongly constricted dorsad, regularly but slightly ex- 

 panding ventrad of the inter-antennal region, biseriate punctate 

 dorsad of the ocellus; eyes subreniform, rather sharply angulate dor- 

 sad, about equal in length to the infra-ocular portion of the genje; 

 antennjv slightly depressed proximad. Pronotum with the cephalic 

 margin slightly arcuate, caudal margin very obtusely angulate, the 

 angle rounded, lateral carina? moderate)}^ distinct, obsolete mesad, 

 moderate!}' constricted, the carina? regularl}' and moderately diverging 

 caudad; median carina distinct, low, cut slightly in advance of the mid- 

 dle; lateral lobes of the pronotum about a third again as deep as long, 

 the cephalic and caudal margins subparallel, ventral margin o])tuse- 

 angulate, slightly emarginate cephalad. Tegmina moderately elongate, 

 exceeding the apex of the abdomen by little less than the combined 

 length of the head and pronotum, exceeding the tips of the caudal 

 femora by nearly the length of the pronotum; costal dilation moder- 

 ate; tips rotundato-truncate; postradial area roughl\" biareolate distad, 

 no distinct intercalary vein present. Caudal femora slender, proximal 

 portion moderately inflated, distal portion regularly narrowed, pattern 

 of the pagina distinctly and sharply sculptured; caudal tibiae with ten 

 latei'al spines present, longer internal spurs slightly more than twice 

 the length of the shorter, comparatively straight except for the 

 recurved and hooked tips. 



General colors prouts brown and ochraceous, a median pale line 

 extending from the fastigium to the tips of the anal area of the 

 tegmina. Head with the median line broad, flanked laterad by large 

 blotches of darker, which replace the postocular bars and extend around 

 the caudal margin of the eye to the infra-ocular sulcus, which is broadly 

 infuscate to the angle of the mandible; eyes cinnamon; antenna? pale 

 ochraceous, infuscate distad. Pronotum dark above, excepting the 

 median line, with the lateral carinse very faintly marked with lighter; 

 lateral lot)es slightly suffused dorsad, the usual oblique blotch very 

 deep in color and large in size. Tegmina with the suffusions rather 

 weak, the dark areas wide and unbroken except distad, costal area 

 hardly suffused. Caudal femora pale, with very slight indications of 

 transverse bai's dorsad, lateral face dark brown inmiediately along the 

 ventro-lateral carina, otherwise unmarked; genicular region brown- 

 ish; proximal two-thirds of the' ventral surface very dark verditer 

 blue; caudal tibife with the proximal two-thirds orange, distal third 

 very dark verditer blue, spines two-thirds blackish; tarsi washed above 

 with the blue of the tibiae.
