heavy, in length exceeding that of the head and pronotum combined by 

 that of the head alone. Pronotum with the disk but very slightly tectate, 

 prozona contained about one and three-fourths in the metazona; cephalic 

 margin very slightly arcuate, caudal margin rectangulate with the 

 margins slightly undulate; median carina very faintly indicated on the 

 prozona, distinct but very fine on the metazone; lateral angles faintly 

 tuberculate on the prozone, rounded shoulders on the metazona; lateral 

 lobes of the pronotum with the depth slightly exceeding cephalad trend, 

 ventral margin irregularly rounded. Interspace between the metasternal 

 lobes slightly transverse. Tegmina four and a half times the length of 

 the pronotum, exceeding the apices of the caudal femora and the abdomen 

 by the pronotal length, the greatest width contained about four and a half 

 times in the length ; costal margin with the distal third regularly arcuate, 

 apex obliquely truncate; intercalary vein closer to the median than to 

 the ulnar vein throughout its length. Wings ample, rather broad, the 

 greatest width contained about one and three-fourths times in the length; 

 apex obliquely truncate, axillary field with the margin distinct arcuate. 

 Abdomen with the subgenital plate rather broad; cerci simple, straight, 

 substyliform, blunt. Cephalic and median limbs rather slender;, caudal 

 femora robust, not strongly but regularly inflated, the ventral carina dis- 

 tinctly elevated, length about two and one-half times that of the pro- 

 notum ; caudal tibiae with nine spines on the lateral margins. 



General color pale ochraceous-buff, overlaid with bistre. Head pale 

 ventrad and on the face, dark dorsad, genae lightly mottled; eyes burnt 

 umber; antennae, except for the paler two proximal joints, clove brown. 

 Pronotum nearly uniform bistre. Tegmina with solid median and 

 proximal dark transverse bars, the latter confluent with the base of the 

 tegmen and both extending solidly across the same; a premedian bar is 

 present, but not as regular as the others, the pale interspace between the 

 three bands being sharply denned and distinctly but not greatly narrower 

 than the average of the dark bars; apical fourth changing from sub- 

 hyaline to hyaline, with about a half dozen subquadrate blotches of the 

 darker color. Wings with the band clove brown in color, crossing the 

 wing immediately distad of the middle, extending in a complete arc from 

 the costal to very near to the internal margin, regularly narrowing in 

 width from the axillary field caudad, the width on the axillary field being 

 about two-sevenths the length of the tegmin, spurs hardly indicated; disk 

 pale sulphur yellow; apical area hyaline except for several blotches of 

 dark color, no suffusion, however, being present. Abdomen dull Naples 

 yellow. Caudal femora of the lighter general color inclined to vinaceous 

 pink on the ventral portion of the lateral face, dorsal and bounding carinas 

 of the paginae sparsely beaded, face of the paginae suffused with the dark 

 color, broad pregenicular annulus of the pale color laterad; genicular 

 regions mingled drab and bistre, internal and ventral face of the femora 

 blackish except for the pregenicular annulus and a proximal portion, both 

 of which are Chinese orange ; caudal tibiae orange vermilion, the genicular 

 section and tips of the spines black; caudal tarsi buffy ventrad, washed 

 with orange vermilion dorsad. 



Measurements: Length of body, 38.5 mm.; length of antennas, 19 mm.; 

 length of pronotum, 9 mm. ; length of tegmen, 39.5 mm. ; length of caudal 

 femora, 21.5 mm. 



The type is the only specimen of this handsome species seen by the 

 author. 



A male and female of this species were sent to Mr. Rehn, of the 

 Academy of Natural Science of Philadelphia, for comparison with the 

 type. The following is taken from his letter: "I have compared the 

 specimens with the type of magnified, with the following results: Your 

 male is distinctly smaller, with the frontal costa more deeply sulcate and
