by an interspace very slightly wider than that between the meso- 

 sternal lobes in the female. Abdomen carinate dorsad; terminal dor- 

 sal abdominal segment of the male with five small black points on 

 the apical margin; supra-anal plate of the male slightly arcuate in 

 section, the margins deflected dorsad, the shape of the plate acute- 

 angulate, the surface with about nine small blackish nodes arranged 

 in rows wliich reading caudad are four, two, one, and two; cerci 

 short, rather tliick, simple, styliform; subgenital plate moderately 

 produced, compressed, sub-lamellate caudad, the apex when seen 

 from the side blunted acute-angulate; ovipositor jaws slender, mar- 

 gins of dorsal pair blunt dentate-crenulate. CephaHc and median 

 limbs very short, the femora sHghtly inflated in the male. Caudal 

 femora about five-eighths the length of the tegmina, moderately 

 slender, pagina with a rather close but not very regular pattern; 

 caudal tibiae somewhat shorter than the femora; caudal tarsi with 

 the proximal joint very appreciably expanded laterad. 



General color of the male russet, of the female mummy brown, 

 the latter with the tegmina mottled with wood brown in quadrate 

 patches, the anal area cliiefly of the latter color, while the median 

 region is chiefly mummy brown. ' Eyes raw umber. Tegmina and 

 caudal femora of the female inchned toward fawn, the cephahc and 

 median limbs and caudal femora of the female blotched much as on 

 the tegmina, but the darker color is nearer seal brown; internal face 

 of the caudal femora orange vermilion crossed by four bands of black — 

 one apical, one preapical, one premedian, one proximal. Caudal 

 tibise scarlet vermilion on half their length in the female, two-thirds 

 of their length in the male, the proximal remainder similar to the 

 femora in both sexes; spines with their apical halves black. 



Measurements. 



A series of one male and three female topotypic specimens have 

 been examined, all taken in June. In size the females are all smaller 

 than the type of that sex, but no striking structural variations are 

 apparent. All of the topotypic specimens agree with the male type 

 in color, a few, however, showing traces of the mottled tegminal 

 pattern.
