longer than the combined length of the succeeding tarsal joints and the 

 bristles on its ventral surface are heav\'. 



Allotype: $ ; same data as type. [Hebard Coll.] 



Differs from the male in the following characters. Abdomen broader. 

 Distal tergite with a low and feebly striate, transversely oval convexity 

 above the base of each arm of the forceps and bearing mesad on the caudal 

 margin a small but conspicuously projecting node, directed dorso-caudad. 



Pygidium about as wide at base as an arm of the forceps, strongly 

 declivent and showing a strong transverse convexity ; with a very narrow, 

 transverse horizontal flange at apex ventrad, terminating on each side in a 

 minute point, which is concealed except when the forceps are somewhat 

 opened. 



Forceps well separated, with a weak curvature, as in the male; dorsal 

 surface flattened proximad, narrowing to distal portion and there terminating 

 at the external margin ; internal surface deplanate in proximal three-fifths, 

 with dorsal and ventral margins coarsely and irregularly denticulate, thence 

 with ventral margin developed into a weak flange, its margin slightly irregu- 

 lar, terminating near apex of forceps.

The great individtial size variation, sometimes fotind in species 

 of Dermaptera, is well exemplified by the females measured.
