the infra-ocular sulcus in botli sexes; antennte about as long as 

 (male) or distinctly" shorter (female) than the head and pronotum 

 tog-ether, distinctly but not strongly ensiform, more marked in the 

 female than in the male, apex acute. Pronotum moderately deplanate 

 dorsad, the greatest width contained about once and a half in the length 

 in both sexes; cephalic margin subtruncate, caudal obtuse-angulate, 

 rather rounded in the male, lateral margins carinate, subparallel; 

 metazona veiy slightly shorter than the prozona in the male, distinctly, 

 though not greatl}' so, in the female; median carina very distinct, cut 

 only by the principal sulcus; lateral lobes subquadrate, the greatest 

 dorsal length slightly greater than the depth, ventral angles rectangu- 

 late. Interspace between the mesosternal lobes slightly longitudinal 

 in the male, ver}^ distinctly longitudinal in the female; metasternal 

 lobes contiguous caudad in the male, subcontiguous in the female. 

 Tegmina slender, elongate, exceeding the abdomen considerably and 

 the tips of the caudal femora slightly in both sexes, apex rounded; a 

 broken irregular intercalar}' vein, more distinct distad and evanescent 

 proximad present in both sexes. Cerci styliform, rather robust, some- 

 what exceeding the supra-anal plate; subgenital plate produced into a 

 compressed process with an acute apex. Caudal femora slender, mod- 

 erately inflated in the proximal half; caudal tibiae bearing eleven or 

 twelve spines on the lateral margins. 



General color mars brown dorsad, wood brown veiitrad; spines of 

 the caudal tibia3 with blackish tips. The female bears distinct seal 

 brown lines extending from the vertex to the caudal margin of the 

 pronotum mesad of the lateral carinte, and a parallel pair from the 

 eyes to and over the pleura, where they merge into a single bar. Lat- 

 eral carinas of the pronotum and a pair of lines on the head, which are 

 cephalic continuations of the carinal stripes, ocher yellow; ventro- 

 lateral portion of the head and the ventral section of the lateral lobes 

 butf. Caudal femora with the dorsal section of the pagina clouded 



with dull blue brown.

Male. Female. 



Two paratypic females have been examined, one taken in August, 

 the other in September. These specimens both represent the uniform 

 type of coloration exhibited by the male, the August specimen, how- 

 ever, having the ventro-lateral section of the head and the ventral 

 portion of the lateral lobes yellowish, while there are traces of the j^el- 

 lowish lines on the head and pronotum.
