of which the first, fifth and sixth of the longer spines are more ro- 

 bust than the others of that category; discoidal spines four in num- 

 ber, the distal one small: cephaUc tibiae slightly less than half 

 the length of the femora, external margin with five spines, with 

 a large proximal diastema, internal margin with nine spines, in- 

 creasing in length distad, apical claw large: cephalic metatarsi 

 very slender, elongate, in length faintly longer than the tibiae (with- 

 out claw), proximad sigmoid, remaining cephalic tarsal joints about 

 two-thirds as long as the metatarsus. Median and caudal limbs 

 very elongate and slender, the median femora subequal to the pro- 

 notum in length, the caudal femora almost half again as long as 

 the median femora. 



General color wood brown, overlaid with a finely punctulate pat- 

 tern and clouding of bone brown to fuscous. Head with the ocellar 

 region solidly, and the facial shield almost solidly, fuscous; eyes 

 broadly blotched with fuscous on the ground color; antennae of the 

 general color, weakly infuscate distad. Lateral portions of the pro- 

 notal shaft heavily blotched with fuscous. Tegmina snuff brown, 

 the marginal field solidly clove brown, the costal margin narrowly 

 but strikingly lined with light buff, this weakening distad; discoidal 

 field with a very short section of each of the cross-veins adjacent to 

 the longitudinal veins lined with clove brown; distad the longitu- 

 dinal veins show a pencilling of clove brown. Exposed portion of 

 wings colored similarly to the distal section of the tegmina. Limbs 

 with the pale base color evident on the carinae of the coxae and 

 femora; external face of the cephalic femora heavily clouded with 

 fuscous, internal face with a heavy blotch of fuscous at the ungual 

 groove; cephalic tibiae with three incomplete annuli composed of 

 fuscous blotches. 



Greatest width of head across eyes, 3 mm; length of pronotum, 

 5.6; greatest width of pronotum across expansion, 1.5; length of 

 tegmen, 17.2; greatest width of tegmen, 4; length of cephalic femur, 

 4.9; length of caudal femur, 8.6. 



The type of this species is unique.

 This specimen appears, in the light of Giglio-Tos' comments'^ 

 and a re-examination of all of Serville's remarks, to be the same as,
