femora. Caudal femora moderately robust, tapering, surpassing 

 the apex of the ovipositor and falling but slightly short of the tips 

 of the wings; caudal tibiae subequal to the femora in length, very 

 slender, the dorsal margins armed with three pairs of spurs, which are 

 not paired in position, those of the external: margins being more proximal 

 in position than the corresponding spur on the internal margin, the 

 spurs slender, slightly falcate or but faintly hooked at the apex, 

 their length about two and one-half times the depth of the tibial 

 shaft; disto-external spurs very short, the median one three times 

 as long as the dorsal and nearly twice as long as the ventral one; 

 disto-internal spurs two in number, elongate, weakly falcate, the 

 dorsal one about one-half as long as the metatarsus and half again 

 as long as the ventral one: caudal metatarsi about one-fourth as 

 long as the tibiae, straight, the dorsal surface with a short recumbent 

 spine on each margin distad, the internal distal spur about one- 

 half again as long as the external one; second tarsal joint elongate 

 cordiform, the third slender. 



Allotype: c/' ; same data as type. January 26, 1912. 



Differing from the description of the type in the following features: 

 Tegmina relatively narroAv when seen from the dorsum (the pair 

 in repose), narrowing distad: lateral field of the tegmina relatively 

 broad, subequal in width; mediastine vein diverging regularly from 

 the humeral vein distad, the area between with a number of trans- 

 verse nervures which divide it into rectangulate spaces; three free veins 

 are present in the proximal section of the lateral field costad of the 

 mediastine vein: humeral vein curving costad at its apex: speculum 

 elongate diamond-shaped, its length about one-half that of the 

 dorsal field of the tegmen, its greatest length slightly more than 

 one-half its length; postaxillary veins three in number; axillary veins 

 two in number. Styles reaching to the apices of the caudate wings. 



General color buff-yellow, the pubescence largely golden. In 

 the female there is a medio-longitudinal line of raw umber on the 

 closed tegmina, which is distinct proximad and weakens distad. Eyes 

 fuscous-black; antennae distad of the proximal joint blackish, the prox- 

 imal one washed distad with fuscous; second and third tarsal joints of 

 all tarsi washed with fuscous-black; ovipositor rich chestnut bro'v\Ti.
