rounded when seen from the side, the dorsal free margin V-shaped, 

 the apex faintly rostrate produced, the proximal section of the V-form 

 of the margin slightly embracing the ventral ridge of the palHum. 

 Cephalic and median limbs moderately robust. Caudal femora 

 moderately robust, very faintly shorter than the tegmina, the great- 

 est depth contained three and one-half times in the length of the same, 

 genicular lobes moderately acute, external face regularly patterned: 

 caudal tibiae slightly shorter than the femora, armed on the external 

 margin with six spines, internal margin with eight spines: caudal 

 tarsi very slender and elongate, the proximal and second joints sub- 

 equal in leng-th. 



Allotype: 9 ; Igarape-assii, State of Para, Brazil. (H. S. Parish.) 

 [Acad. Nat. Sci. Phila.] 



Differing from the description of the type in the following features. 

 Size medium. Interocular portion ofthe vertex slightly wider than 

 the proximal antennal joint, weakly sulcate: fastigium distinctly but 

 not strongly transverse : frontal costa twice as wide as the interocular 

 portion of the vertex, of similar structure to that of the male but 

 the broad portion is plane and non-sulcate, roughly biseriate punctate, 

 ventracl of the ocellus even more strongly constricted and sulcate 

 than in the male, thence obsolete: eyes less prominent than in the 

 male, one and two-thirds times as long as the infra-ocular portion of 

 the gense, in basal outline slightly broader proportionately than 

 in the male : antennae nearly twice as long as the head and pronotum 

 together, very slender, filiform. Pronotum with the median carina 

 obsolete except on the metazona, where it is weak but distinct: 

 lateral lobes with the greatest depth very faintly greater than the 

 greatest dorsal length of the same. Interspace between the meso- 

 sternal lobes with its cephalic width equal to about one and one- 

 third times the greatest length of the same, the form of which latter 

 expands caudad: metasternal. lobes separated by an interspace 

 which at its narrowest point (caudad) is subequal to its greatest 

 length. Ovipositor valves robust, short, the external margins of 

 the dorsal valves crenulate. 



General color of the female saccardo olive, becoming weakly 

 mummy brown on the dorsum of the pronotum and faintly so on 

 the face; of the male on the head, pronotum and pleura dusky olive- 

 green, on tegmina buffy citrine. Eyes cinnamon-brown (d^) to 

 prout's brown (9); antennae fuscous, becoming black distad, with 

 the extreme apex narrowly vinaceous-rufous, proximal joint more 

 (cf ) or less ( 9 ) completely raw sienna. Wings very weakly washed
