than long, maroins as in the male, the sutural margins overlapping 

 for the greater ])()rtion of their length, with their form much the same 

 as in the male. Disto-dorsal abdominal segment and the supra-anal 

 plate similar in form to that found in the male, but the terminal 

 tubercle of the latter is broader and less evident; cerci very short, 

 crassate, tapering, apex acute; ovipositor with the length about one 

 and one-half times that of the cephalic femora, moderately heavy, 

 the dorsal margin regularly and distinctly arcuato-concave, ventral 

 margin straight except at the extreme proximal and distal extremities, 

 at the latter well arcuate dorsad to the subacute apex, for the distal 

 third of the dorsal and a fourth of the ventral margins strongly 

 serrato-dentate; subgenital plate transverse, distal margin bis- 

 arcuate emarginate, produced into brief trigonal lobes laterad. 

 Cephalic femora slightly less than one and one-half times the length 

 of the disk of the pronotum. Median femora al)out one and two- 

 thirds times the length of the pronotum. Caudal femora with their 

 length distinctly exceeding that of the body (exclusive of that of the 

 ovipositor).

Color Notes. — Both specimens of this species seen by us have been 

 at some time immersed in a liquid preservative which has completely 

 removed their original color, leaving them in general a pale ochraceous. 

 Fortunately, however, sufficient of the pattern remains to enable us 

 to give a few notes on "the same. Caudal portion of the occiput, 

 which area is usually covered by the pronotum, seal brown, a very 

 fine postocular line of the same and sometimes a similar weak 

 medio-longitudinal line on the occiput present, the post-ocular 

 continued ventro-cephalad across the eye; antennae irregularly but 

 very closely and strikingly annulate with seal brown. Pronotum 

 with the disk margined laterad with fine continuations of the post-
