produced, caudo-lateral margins rect-convergent, crassato-cingulate, caudo- 

 lateral angles obtuse, faintly strumose; caudal margin truncate: surface of the 

 disk subimpressed transversely mesad, laterad near end of fissures are indicated 

 paired sinuate sulci, which sever the black markings described under color; 

 surface of "wings" folded, ventral surface of same deeply and broadly chan- 

 nelled, the angle at extremity of fissure strongly thickened and elevated. 

 Tegmina elongate, briefly passing the apex of the abdomen, sublanceolate, 

 greatest width contained nearly three times in the length: costal margin 

 arcuate in proximal half, more decidedlj' so at the very base and weakh- flat- 

 tened at proximal third, from middle to distal fourth the margin is very faintly 

 concavo-emarginate, thence rounding to the roundly acute apex; sutural mar- 

 gin arcuate in proximal fourth, distal fourth obliqueh^ subtruncate to the apex, 

 remainder of this margin straight : marginal and scapular fields broad, elongate, 

 the former almost entirely cribroso-reticulate, the scapular and distal section 

 of the marginal fields with regular, close and arcuate rami of the mediastine 

 and discoidal veins; anal field elongate subpyriform, in length equal to two- 

 fifths of the entire tegmen: venation decided, standing in relief, distad on dis- 

 coidal field regularly quadrato-reticulate; discoidal vein bifurcate toward 

 sutural margin; mediastine vein bifurcate; ulnar vein with five rami; anal vein 

 arcuate, joining the sutural margin at nearly a right angle; axillary veins 

 numerous. Wings faintly surpassing the apex of the abdomen, apex similar 

 in form to that of wing; premediastine area opaque for the greater portion of its 

 length; mediastine-discoidal and medio-discoidal areas narrow, quadrato- 

 reticulate in proximal two-thirds; discoidal vein bifurcate at distal third; ulnar 

 vein with four to five rami reaching the free margin of the wing and six term- 

 inating at or in the vicinity of the anal vein. Supra-anal plate transverse, 

 broadly bilobato-emarginate distad; cerci rather short, tapering, composed of 

 twelve very short segments, apex rather blunt; subgenital plate small, trans- 

 verse, arcuate distad with pronounced juxta-cercal emarginations, in each of 

 which is placed a minute simple style. Limbs very short. 



General color shading from antimony yellow on the pronotal disk through 

 warm buff to light buff distad on the dorsal surface of the abdomen. Head 

 with the interocular section of the occiput ochraceous-orange, passing through 

 ferruginous on the facial section of the same interspace into liver brown on the 

 remainder of the face; mouth parts light orange-yellow; eyes hair brown; 

 antennae liver brown proximad, passing into cinnamon-rufous. Pronotura 

 shading from the antimonj' yellow of the greater portion of the disk into warm 

 buff on the lateral "wings" and cephalic margin; disk with a pair of well sepa- 

 rated broad comma-shaped fuscous marks placed on the transverse median 

 line; margins of the fissures and caudo-lateral margins ferruginous, the caudal 

 margin fuscous, the caudo-lateral angles more broadly so. Tegmina sub- 

 hyaline except proximad on the marginal field; the venation of the marginal 

 and anal fields warm buff, of the discoidal field walnut brown. Wings with 

 venation whitish. Mesonotum with cephahc half chestnut brown, shading 

 caudad into the general colors. Dorsum of abdomen with broad lateral clouds 

 of mummy brown, paling mesad and along lateral margins within a regularly 

 defined area much broken up by light buff dots and clouds; supra-anal plate 

 mummy brown touched with light bufi"; cerci mummy brown, on dorsal surface
