somewhat shorter than body. Pronotum subtrigona! in outline, 

 greatest length contained one and one-half times in width, cephalic 

 margin narrow, subarcuate, rounding to the oblique gently arcuate 

 lateral margins, caudal margin subtruncate, caudo-lateral angles 

 rounded rectangulate ; disk in transverse section subarcuate, slightly 

 more bent laterad and subdepressed dorsad ; margins strongly cingulate 

 laterad; surface with no distinct sulci. Tegmina sublanceolate, 

 non-attingent, about as long as pronotum, reaching to apex of first 

 abdominal segment, greatest width contained one and one-quarter 

 to one and one-third times in length, apex rounded acute, costal 

 margin considerably arcuate; interspace between tegmina equal to a 

 third of width of tegmen; venation reduced, anal sulcus distinct and 

 reaching more than half way to apex. Wings abbreviate, almost as 

 long as tegmina. Supra-anal plate transverse trigonal, apex rounded, 

 margins very slightly concave; cerci depressed, fusiform. 



General color varying from uniform pitch black to pitch black and 

 burnt sienna, the latter in extreme form most distinct on head, anten-

 and venter of abdomen. Limbs varying from s *\ = / > ' ^^xU^

 18.5 mm.; length of pronotum 3-3.5 mm.; N.C.: female; Ches- 

 greatest width of pronotum 4-4.8 mm. ; length 

 of tegmen 11.5-14.6 mm.; greatest width of tegmen 3.5-4.6 mm. 



9 . Length of body 10.5-13.5 mm. ; length of pronotum 3.5-3.8 mm;

Distribution. — The range of this species is now known to extend 

 from eastern Massachusetts (Wellesley) and northeastern Indiana 

 (Steuben County) south to southern Florida (Dade County) and west 

 to eastern Texas (Hockley). Its zonal distribution appears to be 

 Upper and Lower Austral, trespassing on the lower portion of the 

 Transition. 



Remarks. — In the male sex this species appears to decrease in size 

 southward, Georgia and Florida material of that sex being considerably 

 smaller than New Jersey and North Carolina individuals, although the 

 single Texan male seen is equal in size to North Carolina specimens 

 In the female sex, however, this geographic variation is not apparent, 

 and it is possible that the apparent size correlation in the male may
