merous and weakly indicated, except on the normally covered section of the 

 dextral tegmen, where they are quite distinct; anal field elongate pyriform. 

 Wings reaching to the tegminal apices; costal veins numerous and moderately 

 clavate distad; medio-discoidal and medio-ulnar areas in general subequal in 

 width; ulnar vein with one large ramus; intercalated triangle distinct, of fair 

 size. Abdomen broad, depressed, distal extremity of the abdomen consid- 

 erably narrowed; penultimate dorsal segment broadly obtusc-emarginate 

 distad; disto-dorsal abdominal segment arcuate-truncate mesad; supra-anal 

 plate transverse, margin obtuse-angulate with a distinct short, narrow, median 

 fissure, the plate depressed on each side of the median area, which in section is 

 tectate; cerci depressed subfusiform, apices imperfect in type; subgenital 

 plate scoop-shaped, rather more produced and compressed than in related 

 forms, the apex is very narrowly emarginate-truncate. Cephalic femora with 

 ventro-distal margin bearing three median and two distal (apical) long spines, 

 the margin between with a fairly closely placed series of much shorter spines. 

 Caudal tarsi slightly shorter than the caudal tibiae, the metatarsus suljequal in 

 length to the remaining tarsal joints; arolia on all tarsi. 



General color pale yellow ocher, the veins of the wings and of the normally 

 covered portion of the dextral tegmen dresden brown. Head with occiput 

 and interocular region antimony yellow, crossed by a decided transverse bar 

 of cinnamon-brown; maxillary palpi light buff; eyes mars brown. Pronotum 

 with the disk opaque antimony yellow with five pairs of more or less broken 

 lines of ochraceous-tawny; these lines vary in thickness and intensity, but, 

 aside from the parallel median pair, are arranged in an appreciably concentric 

 pattern. Tegmina with the normally covered portion of the dextral tegmen 

 whitish. Dorsum of abdomen mummy brown with the segments margined 

 laterad with, and the distal segments divided mesad by, light ochraceous- 

 buff; venter of abdomen in ochraceous-buff with a paired intermarginal bar 

 on each side, coming to a point at the cereal bases, and a median bar, which 

 is very broad proximad, tapering mesad and narrow and subequal on the sub- 

 genital plate, mummy brown. Cerci mummy brown ventrad and at dorsal 

 base.

In addition to the type we have examined a paratypic female 

 from the type locaHty and another female (minus the abdomen) 

 from Independencia, Parahyba, Brazil (Mann and Heath). 

 These specimens show no important features of difference from 

 the description of the type. The oyos are seen to vary in color
