with thirteen spines which are biseriate in position proximad and throughout in 

 length; cephalic tibiae (exclusive of claw) subequal to one-half the femoral 

 length, armed on the ventro-external margin with fourteen spines, these 

 increasing in length distad, ventro-internal margin with fourteen or fifteen 

 spines increasing in length distad, terminal claw large; cephalic metatarsi 

 about three-fifths of the tibial length, remaining tarsal joints about two-thirds 

 of the length of the metatarsus. Median and caudal femora of medium length; 

 femora with the usual distal lobe on the ventro-caudal margin represented by 

 only the merest expansion of the margin, genicular spine aciculate; tibiae 

 subcompressed, the dorsal margin lamellato-carinate on proximal half; caudal 

 metatarsi eciual to faintly more than a third of the tibial length. 



Coloration destroyed by immersion in a liquid preservative. Marginal 

 field of the tegmina with veins opaque and purplish-pink, their immediately 

 surrounding section opaque yellow and the greater portion of the area much 

 darker and translucent. Apparentlj^ when uninjured the coloration of the 

 veins of this field is red, surrounded by borders of green or yellow.

Length of pronotum. 



Greatest (supra-coxal) width of pronotum,

Greatest width of tegmen, 



Greatest width of marginal field of tegmen, 



Length of cephalic femur, 



Length of caudal femur. 



In addition to the type we have examined a paratypic female 

 and an immature female from Independencia. The adult is 

 fully tj^pical of the species but is smaller than the tjj-pe, as the 

 measurements given above show, with the tegmina and wings 

 sHghtly shorter proportionately and the femoral lol)es slightly 

 more indicated than in the type, but these latter are no more 

 than one-third as deep as the femora.

Porto Velho, Rio Madeira. (Mann and Baker.) Two 



males. 



These specimens are inseparable from two male indivicluals 



from Cayenne received from Chopard, except that in both of 



the present specimens there is an additional brownish tegminal 



maculation proximad of the larger oblique one present in all.
