and flattened, with a few small, weak depressions and minute widely 

 scattered impressed punctae in caudal portion, which portion laterad 

 is bounded by low rounded ridges, strongly divergent from base of 

 hooded portion, then parellel to the shoulders; surface latero-caudad 

 thickly impresso-punctate, though not as heavily or thickly as in 

 signaticollis. Tegmina and wings fully developed, showing no re- 

 duction whatever and extending well beyond apex of abdomen. 

 Abdomen, including asymmetrical Panchloroid subgenital plate, 

 with straight, elongate, similar styles; limbs short; cephalic femora 

 supplied with a few minute chaetiform spines distad, terminating 

 in a single stout though greatly reduced spine ; other femora unarmed, 

 lacking even genicular spines; large pul villi and large arolia between 

 the simple, symmetrical tarsal claws, all as characteristic of the 

 genus.

Agrees with the type, except as follows. Size larger, form some- 

 what broader, tegmina and wings showing some reduction, reach- 

 ing to base of supra-anal plate. Head broader and more flattened, 

 interocular space three-fifths that between antennal sockets, ocelli 

 smaller. Pronotum broader, the lateral angles slightly more caudad 

 in position, the cucullate and other raised portions minutely and 

 rather thickly impresso-punctate, though by no means as thickly 

 as in the male of signaticollis before us. Subgenital plate large, 

 simple, free margin broadly concave opposite cerci. 



General coloration (of males) deep chestnut-brown; the trans- 

 lucent latero-caudal portions of the pronotum and tegmina, when 

 held to the light, chestnut brown. Pronotum with cephalic third 

 dully transparent warm buff, the darker color invading this area in 

 cucullate portion to near the cephalic margin, the caudal borders 

 on each side straight, transverse, considerably cephalad of the lat- 

 eral angles. Ventral surface cinnamon-buff, the abdominal seg- 

 ments with lateral areas and femora distad paler, buckthorn brown. 

 Antennae blackish brown, becoming chestnut brown proximad. 



The female is similar but darker, more solidly blackish brown, 

 with cephalic third of pronotum dully transparent antimony yellow. 



Length of body cf 18.3«2-18.8, 9 20.7; length of pronotum cf 

 4.9-5, 9 5.3; width of pronotum c^ 7.-7.8, 9 8.2; length of tegmen 

 cT 17.3-17.7, 9 15.2; width of tegmen d' 6-6.2, 9 6.1 mm. 



In addition to the described pair, a paratypic male and five im- 

 mature examples, bearing the same data, are at hand. 



The immature condition is strongly patelliform, the dorsal sur- 

 face minutely and thickly tuberculate, these interspersed with more 

 prominent tubercles. 



General coloration verona brown, beautifully and symmetrically 

 marked with cinnamon-buff. Transparent portion of pronotum ceph- 

 alad ochraceous-buff, other segments streaked laterad and punct-
