190 BRAZILIAN DERMAPTERA AND ORTHOPTERA 



slightly transverse, broad scoop-shaped, the lateral margins converging distad to 

 the base of the styles, which are simple, styliform, acute processes, parallel in 

 disposition and with the margin between their bases weakly arcuate, the length 

 of the styles liut shghtly less than half the length of the plate. Cephalic 

 limbs moderately slender: cephalic coxae but slightly shorter than the prono- 

 tum; cephahc femora slightly longer than the pronotum, weakly compressed, 

 the greatest depth of the femur contained about four and one-half times in the 

 length of the same; discoidal spines four in number; external margin with five 

 to six spines, of which the distal one is on the genicular lobe; internal margin 

 with twelve spines, alternating large and small : cephalic tibiae (exclusive of the 

 apical claw) two-fifths as long as the femora, straight, armed on the external 

 margin with five spines, proximad of which is a considerable unarmed diastema, 

 internal margin armed with ten spines, these increasing in size distad; cephalic 

 tarsi with the metatarsi slightly longer than the tibiae, remainder of the tarsal 

 joints together slightly longer than the metatarsi. Median and caudal limbs 

 very slender and elongate, the median femora slightly longer than the length 

 of the head and pronotum combined, the caudal femora when extended caudad 

 slightly surpassing the apex of the abdomen, caudal metatarsi three-fourths as 

 long as the pronotum, the remaining joints of the caudal tarsi not more than 

 three-fifths as long as the metatarsus. 



General color mummy brown on the head, russet on the thorax and limbs, 

 passing into sayal Ijrown on the abdomen, the tegmina and wings faintly washed 

 with .snuff l)rown. Ocelli deep, clear bay; eyes fuscous mottled with raw 

 umber; eyes brussels brown, darkening distad. Pronotum weakly vermicu- 

 late with fuscous. Tegmina with the cross veins of the discoidal field and in 

 the vicinity of the humeral trunk with the section adjacent to the main veins 

 briefly lined with fuscous. A\ings with the humeral trunk, the ulnar, axillary 

 and anal veins with the cross veins in their vicinity lined as on the tegmina. 



Length of body, 26 mm. ; length of pronotum, 6; greatest width of [)ronotum, 

 1.9; length of tegmen, 21; greatest width of tegmen, 5.4; length of cephalic 

 femur, 6; length of caudal femur, 10. 



The type of this species is unique.

Salto Grande, State of Sao Paulo. February, 1911. (H. 

 Lliderwaldt.) One male. 



This specimen is inseparable from the Misiones, Argentina male 

 previously recorded by us," except that the tegmina and wings 

 do not surpass the apex of the abdomen by more than a few mil- 

 limeters, instead of by nearly half the pronotal length as in the 

 other individual.
