 black almost to their base, ten to twelve, usually eleven, in number in 

 the outer series. Extremity of male abdomen rather stron^^ly clavate, 

 well recurved, the supraanal plate subclyi>eate, but very strongly and 

 roundly compressed in the basal half, the apex roundly and rather 

 bluntly rectanpulate, the lateral marj;ins strongly and abruptly elevated, 

 the median sulcus deep, ])ercurrent and apically expanded, bounded by 

 rather high but rounded walls; furcula comjjosed of a jiair of greatly 

 extended, somewhat depressed, straight lingers, tapering by the nar- 

 rowing of their inner margiiis. lying outside the ridges of the supraanal 

 jdate, reaching much beyond the middle of the same, and slightly out- 

 curved at th«'ir rather blunt tips; cerci rather broad at base, rapidly 

 narrowing beyond so as to be hardly half as wide in the middle, beyond 

 subequal, incurved and blunt-tipped, externally punctate throughout 

 and not reaching the tip of the supraanal plate; subgenital plate hardly 

 halfaswideat apex as at base, the lateral margin rapidly decliveut, 

 the apical margin not elevated, strongly rounded, entire.

This species takes in our Southern Atlantic States the place of M. 

 femur-ruhnim, which it closely resembles; it is most quickly distin- 

 guished from it by the form and sculpture of the supraanal i)late and 

 the much greater length of the furcula.
