t>Tnpanum very elongate (deoidcdly more longitudinal than in (jracillvnus or 

 insularis), veins and veiiilets of tegmina decided; wings more than usually 

 narrow. Cerci heavy and not very elongate (decidedly shorter than in insu- 

 laris, a little longer than in C.fasciatus), w'ith mesal portion not contrastingly 

 swollen, armed with a heavy mesal (vertical) tooth, which is flat and broad at 

 the base, situated intern:)-mesad and directed slightly cephalad of peri)eudicular 

 to shaft, distal third of ccrcus showing a distinct but weak outward cm-vature 

 with broadly rounded apex briefly but decidedly depressed. Subgenital plate 

 with distal margin weakly but distinctly convex between the short disto-lateral 

 .styles. Cephalic and median limbs as in insularis, caudal limbs similar to 

 those of that species (swollen proximal portion narrowing more abrui)tly and 

 decidedly than in gracillimus), with genicular lobes bispinose but with ventral 

 margins unarmed. Caudal tibiae with the three pairs of distal sjnirs small, the 

 dorsal pairs and interno-ventral sj^urs being only slightly heavier than the 

 larger tibial spines. 



Allotype: 9 ; data same as type but taken August 7, 1911. 



Description of Allotype. — Very similar to lype with little difference in size. 

 Tegmina similar with exception of sexual ditTerences. Ovipositor very similar 

 to that of insularis, short, very slender, virtually straight but with distal 

 third ha\-ing a very weak upward curvature. Subgenital plate flat, with 

 lateral margins turned upward roundly but sharph' and embracing the base 

 of the ovipositor, brief distal margin of flat surface transverse.
