Description. — d\ Size medium; body moderately depressed; form 

 elongate-elliptical when wings are in repose. Head not completely 

 hidden under pronotum; ocelli moderate in size, interocellar and 

 interocular interspaces subequal; antennse longer than body. Pro- 

 notum semi-elliptical, moderately flattened, caudal margin subtruncate, 

 lateral angles narrowly rounded and lateral portions decidedly de- 

 flected, cingulate, disk with usual convergent sulci more or less distinct. 

 Tegmina exceeding apex of abdomen by more than length of head 

 and pronotum, elongate, subequal, greatest width contained about three 

 and one-half times in length, apex well rounded; venation distinct, 

 costal field short, narrow, punctate. Wings as long as tegmina when 

 in repose, apex well rounded; ulnar vein with from three to five 

 complete rami reaching apex of wing, incomplete rami varying 

 from four to six in number. Supra-anal plate somewhat produced, sub- 

 quadrate, lateral margins obliquely convergent, apex truncate, lateral 

 angles narrowly rounded ; cerci depressed, fusiform-terete, apex acute. 

 General color seal brown on the dorsum becoming blackish on pro- 

 notum, tegmina paler distad. Abdomen, coxa) and head shining pitch 

 black. Wings hyaline with veins raw umber and costal margin and 

 apical portion clouded with same color. Eyes blackish to mars brown; 

 supra- antennal spots more or less ochraceous; antennse blackish.

pendages black. 

 noptera deropeltifor- 9 . Body considerably depressed ; form ellip- 



mis (Brunner). Su- tical-ovate, greatest width abdominal; surface 

 and$(x3). Male; glabrous. Head almost entirely hidden under 



Sulphur Springs, N. pronotum; antennae somewhat shorter than 



C: female; Raleigh, f , ' , • , , 



N. c. body. Pronotum much as in male but more 



5 This is the case with the males seen from Indiana, while rather curiously 

 all the individuals from other localities have the limbs uniform ochraceous.
