is depressed and when seen from the dorsum spatulate: subgenital 

 plate broad, shghtly scoop-shaped, regularly narrowing distad, 

 distal margin of the plate so damaged that its true form cannot 

 be determined, the styles also being missing, but the latter were 

 in all probability well developed, as tubular sockets in which they 

 were placed are indicated in the remaining section of the distal 

 portion of the plate. 



Cephalic femora subequal to the disk of the pronotum in length; 

 cephalic tibiae surpassing the femora in length by about one-fourth 

 of the femoral length, very slender except in the proximal fourth^ 

 auditory tympani elliptical. Median femora half again as long 

 as the pronotal disk; median tibiae surpassing the femoral length 

 by about that of the distal tarsal joint. Caudal femora nearly 

 three-fifths as long as the tegmina, moderately inflated proximad, 

 slender distad, moderately compressed proximad, ventral margins 

 armed with three to four (external) and two (internal) spines ; caudal 

 tibiae one and one-fifth times as long as the femora, compressed, 

 deeper proximad than distad, armed on the dorsal margins with 

 distinct spines, those of the internal margin more numerous than 

 those of the external and differing from those on the latter margin 

 in being erect and not diverging, between the spines is present a 

 continuous, distinct and deep sulcus, ventral margins with rela- 

 tively few spines, these mainly distad. 



Original coloration of the specimen destroyed by immersion at 

 some time in a liquid preservative. Present color wood-brown, 

 the tegmina verona brown. 



Length of body, 17.2 mm.; length of pronotum, 4.9; greatest (cau- 

 dal) width of the pronotal disk, 2.9; length of tegmen, 27; greatest 

 width of tegmen, 6.8; length of caudal femur, 21.2; length of caudal 

 tibia, 18.5. 



The type of this species is unique.

 This specimen fully agrees with the original description and is 

 inseparable from an individual of the same sex from Rio de Janeiro, 

 in the collection of the Academy of Natural Sciences of Philadelphia, 

 w^hich was determined as sulcata by Saussure, from whom it was 

 received. The species has been questionably recorded from Rio 

 de Janeiro by Bruner.
