throughout its length, not high; lateral carina? low, the width 

 between them at the cephalic margin nearly twice 

 that at the first transverse sulcus and but little 

 more than half that at the caudal margin ; lateral 

 lobes very slightly deeper than wide, ventro- 

 cephalic angle obtuse, ventro-caudal angle well 

 rounded. Tegmina reaching to the middle of the 

 genicular arches of the caudal femora, tips rather 

 narrowly rounded. Prosternum moderately inflated, 

 a distinct, transverse, oblong swelling present; in- 

 terspace between the mesosternal lobes distinctly 

 transverse, as wide as one of the lobes ; metasternal 

 lobes subcontiguous. Caudal femora very slightly ~~*^^p 



shorter than the length of the tegmina, considerably ?: 10 . - A 9 eneotet -

inflated proximad, the pregenicular portion quite Dorsal view of 



slender (for the genus) , pattern of the paginse distinct j* ead ar }^ prono- 



and regular but not very deeply impressed; caudal 



tibiae with eight spines on the lateral margins, nine on the internal 



margins. 



General color buff, pale on the venter and abdomen, the dorsum 

 tending toward ochraceous and clay color. The usual'markings found 

 in species of the genus, i.e., on the dorsum of the caudal femora, 

 on the disk of the metazona and bordering the lateral carina? laterad 

 and the narrow postocular line, are distinctly marked in seal brown, 

 the tegmina with a number of small quadrate patches of the same and 

 with the pleura much touched with the same color. Lateral carina? 

 decidedly contrasted, the ventral portion of the metazona of the lateral 

 lobes usually being pale when contrasted with the remainder of the 

 lobe. Face more or less sprinkled with fine spots of bistre, except a 

 pair of areas ventrad of the eyes which are pale. Eyes broccoli 

 brown, suffused more (ventrad) or less (dorsad) heavily with seal 

 brown. Antenna? cream-buff, washed with very dull mauve distad, 

 the extreme tips very pale. Caudal tibia? pale buff or buff yellow, more 

 or less completely washed with very pale and dull mauve and speckled 

 with dark patches proximad, a seal brown genicular annulus present, 

 the spines blackish to their bases. Tarsi buffy, more or less distinctly 

 and strikingly marked with blackish.
