 section of the segment being inflated and with three prominent angles ; 

 tibiae as long as the femora, quadrate, slightly tapering ; first tarsal joint 

 about as long as the succeeding ones. Intermediate femora short, 

 triangular in section, equalling the metanotnm (and median segment) in 

 length ; tibiae depressed, about equalling the femora in length ; first tarsal 

 joint considerably less than the succeeding joints in length. Caudal 

 femora short, reaching the middle of the third abdominal segment, 

 roughly triangular in section ; tibiae rather longer, reaching to the apex of 

 the first segment. General colour reddish brown, washed with ashy gray

Allied to A, Behrensi, Saussure, but much larger, with the pronotal 

 carinas slightly arcuate and very slightly incised ; the frontal costa 

 is suddenly constricted superiorly and not tapering, while the posterior 

 margin of the pronotum is rectangulate, with the angles more or less 

 rounded instead of acute angulate. With nietanna, Saussure, the species 

 needs no comparison. 



o* . Size rather small. Head with the fastigium gently rounded, 

 merging into the frontal costa with a slightly perceptible angle ; vertex 

 decidedly longer than broad, rather deeply excavated, the lateral margins 

 subacuminate cephalad ; frontal costa decidedly constricted dorsad, 

 rather broad ventrad, slightly expanded at the ocellus, the dorsad section 

 bearing a central low ridge, broadly sulcate at and ventrad to the ocellus; 

 eyes sub-elliptical, equal to the ventro-ocular portion of the genae ; 

 antennae short, slightly expanded distad. Pronotum rugose, moderately
