REHN AND HEBARD 89 



The male tegmina project but very slightly caudad of the 

 caudal margin of the pronotal disk, are distinctly vaulted in 

 form with the mirror of the tympanum relatively large. The 

 abdomen has the dorsal and lateral carinae well indicated in 

 both specimens. The disto-dorsal abdominal segment is roundly 

 obtuse-angulate emarginate in the male, more decidedly angulate 

 in the female. The supra-anal plate in both sexes is small, 

 rectangulate, with a medio-longitudinal sulcus. The male cerci 

 are short and robust, the distal portion moderately acute. The 

 male subgenital plate is shghtly acute-angulate emarginate, 

 the styles of medium length, slender .^^ The ov^ipositor of the 

 female is moderately robust and straight, the apex ventral, the 

 length of the ovipositor but little more than two-thirds that of 

 the caudal femur. The subgenital plate of the female is deeply 

 and broadly U-emarginate, the tips of the lateral sections of 

 the plate well rounded. The prosternal spines are of medium 

 length, aciculate; the mesosternal lobes acute, varying in degree 

 in the two specimens, the tips faintly mammillate. Caudal 

 femora elongate, moderately bullate proximad and passing regu- 

 larly into the slender distal portion, the ventro-internal margin 

 with three to five spines; caudal tibiae with the medio-internal 

 distal spur twice as long as the ventro-internal one. 



The immature specimens have an elongate, narrow type of 

 pronotum resembling that of glaber and calcaratus, but with indi- 

 cations, however, in the outline of the disk of the condition of 

 the adult, while the form of the lateral lol)es is distinctly the 

 same. The abdomen is strongly carinate in all these immature 

 individuals. 



Color Notes. — Both adults seen are very dull colored, having 

 little contrast, the general dorsal tone being bone brown to fus- 

 cous, the pale section of the lateral lobes, venter and genae sayal 

 brown in the female, bister in the male. The face is washed 

 with the dorsal color in both adults. The fuscous of the lateral 

 lobes of the pronotum is restricted to the caudal extension of 

 the lateral lobes and the very narrow edging of the region of 

 the humeral sinus is strongly contrasted. The immature speci- 

 mens are in general colored much as the adults, the fuscous 



'^ The male seen has one style normal, the other is replaced by a heavy in- 

 completely articulated process, apparently an abnormal condition.
