parent caudad, severed distinctly caudad of the middle; lateral carinas 

 regularly but not greatly converging caudad to the middle of the disk, 

 where they are separated by about half the caudal 

 width, thence more sharply divergent caudad; 

 lateral lobes slightly longer than deep, ventral 

 margin sinuate arcuato-truncate, ventro-cephalic 

 angle rounded, ventro-caudal angle subrectangu- 

 late. Tegmina rather narrow, slightly ( 9 ) or 

 considerably (c?) exceeding the apex of the abdo- 

 men, but not quite reaching the extremities of 

 the caudal femora, apex narrowly truncate. Inter- 

 space between the mesosternal lobes transverse; 

 interspace between the metasternal lobes longitu- Yig. 11. —Cordill-

 median limbs quite slender, moderately long. h ea( i an( j pr0 no- 



Caudal femora in length slightly shorter than tum - (X 3.) 

 the tegmina, slender; caudal tibise about equal 

 to the femora in length, armed with ten to twelve spines. 



General color ochraceous marked with vandyke brown. Face and 

 mouth parts buff, the frontal costa clay color and a distinct subocular 

 blotch, which is divided by a carinal line of buff, vandyke brown. 

 Gense, portions of the pleura and the ventral portion of the lateral face 

 of the caudal femora hoary white ; ventral portion of the lateral lobes 

 of the pronotum pale buff ( 9 ) or buff y white ( cT ) . Eyes ochraceous lined 

 with narrow bars of vandyke brown ; antennae very pale bluish-green, 

 narrowly tipped with buffy , whitish proximad in the female. Postocular 

 bars and their continuations on the lateral lobes and pleura vandyke 

 brown; a distinct broad median bar is present on the dorsum of the 

 head. Dorsum of the pronotum with buff predominating, the median 

 area somewhat infuscated, the usual trigonal caudal blotches vandyke 

 brown. Tegmina with the crenulate maculations of dull whitish 

 against vandyke brown, the crenulations more numerous in the male 

 than in the female. Caudal femora with the dorsal portion of their 

 lateral face vandyke brown, the dorsum with three indistinct vandyke 

 brown bands, of which the proximal is suboblique; caudal tibia? dull 

 lavender distad and mesad, spine tipped with black.
