supracoxal tlilation, posterior two-thirds of the shaft subcqiial; dorsal 

 surface finely tuberculate, a strong longitudinal sulcus present on the 

 postei-ior half of the collar and the anterior half of the shaft; margins 

 strongly denticulate except on the anterior portion of the collar; 

 acetabular spine erect, robust. Tegmina short and rounded, not 

 reaching the apex of the abdomen; costal margin strongly arcuate, 

 sutural margin moderately so, apex obtuse-angulate ; costal field at 

 the widest point equal to one-half the width of the entire tegmina; 

 stigma corneous, slender, subfusiform,^' longitudinal. Wings about 

 equalling the tegmina in length when in repose. Abdomen strongly 

 expanded. Supra-anal plate triangularly^ produced, the apex obtuse- 

 angulate. Cerci attenuate, about equal^o the subgenital plate in 

 length. Subgenital plate produced, apex rostrate. Anterior coxa; 

 slightly shorter than the pronotum, superior margin serrate, lower mar- 

 gin with elongate dentiform spines; femora equal to the pronotum in 

 length, superior margin bearing a large, rounded, foliaceous expansion 

 on the apical two-thirds of the joint, lower external margin bearing four 

 large spines, two medium-sized apical spines,^and a series of small blunt 

 spinous tubercles between the largest spines, discoidal spines four in 

 number, closely placed, internal margin anterior to the discoidal spines 

 bearing a series of thirteen spines, posterior to the discoidal spines a 

 series of five blunt tubercles ; tarsi somewhat exceeding half the length 

 of the femora, the superior margin bearing an arcuate foliaceous 

 ridge, external margin bearing a series of seven spines, the basal por- 

 tion unarmed, the internal margin bearing a series of fourteen spines; 

 metatarsi stout, slightly longer than the remaining joints united. 

 Median and posterior limbs rather robust ;, femora armed with genicular 

 spines, the genicular lobes rounded; posterior metatarsi not two-fifths 

 of the total tarsal length. 



As the specimens examined are all from alcohol, and consequently 

 with the natvu'al colors destroyed, no color notes can be given.
