slightly Jacute-angulate with the apex blunt, surface but slightly de- 

 pressed in]^the form of a crescent; lateral foveolse entirely visible from 

 the dorsum, sublinear, slightly arcuate, not deeply impressed; face 

 moderately retreating; frontal costa regularly expanding ventrad, 

 sulcate and impressed for a distance ventrad of the ocellus, punctate 

 dorsad ; eyes somewhat acute-ovate, not very prominent when viewed 

 from the dorsum; antennae about as long as the head and pronotum, 

 depressed and slightly expanded proximad. Pronotum somewhat 

 constricted mesad ; cephalic margin of disk slightly 

 arcuate, caudal margin obtuse-angulate; median 

 carina distinct and well elevated, severed by the 

 transverse sulcus slightly caudad of the middle, 

 lateral carinse slightly less elevated than the 

 median, arcuate convergent on the cephahc third 

 of the disk, at a third the length from the cephalic 

 margin they are separated by a space but little 

 more than half that separating them at the cephaUc 

 margin, from which point of greatest proximity 

 they diverge in straight line to the caudal margin 

 where they are slightly more distant than cephalad ; 

 lateral lobes as deep as long, ventral margin 

 obtuse-angulate. Tegmina exceeding the apex 

 of the abdomen by about the dorsal length of the 

 head, narrow, tips rounded; intercalary vein dis- 

 Pig. 9.—Horesidotes tinct and continuous, at least distad; lobe on the 

 DOTsalvfewo^head costal margin small. Interspace between the 

 and pronotum. mesosternal lobes subquadrate, narrower than 

 ^^ '^ the width of one of the lobes; metasternal lobes 



subcontiguous caudad. Cephahc and median hmbs of medium build. 

 Caudal femora three times the length of the pronotum, rather robust; 

 caudal tibiae slightly shorter than the femora, armed on the external 

 margin with ten spines, internal spurs subequal. 



General dorsal color prout's brown, obscurely sprinkled and mottled 

 with Vandyke brown; general ventral color ochraceous-buff becoming 

 very pale yellowish on the abdomen. Head with the face and ventral 

 half of gense ochraceous-buff sprinkled with vandyke brown, mouth- 

 parts rufous ; eyes clay color mottled with vandyke brown ; antennae 

 rufous becoming olive-buff distad. Pronotum with the disk slightly 

 paler than the dorsal half of the lateral lobes, line between dorsal and 

 ventral color slightly below the middle of the lateral lobes, sinuate, 

 sharply defined ; an isolated bar of the ventral color is present dorsad
