 except at the extreme front; front inarjj^in truncate, hind margin obtus- 

 anj;ulate; jirozona quadrate or feebly lon;;itudinal (mah') or feebly

 between narrow and sharp ridj;es, terminating abruptly; furcula con 

 sisting of a ])air of slight spinous denticulations shorter than the last 

 dorsal segn)ent, overlying the base of the submedian ridges of the 

 8ui»raanal plate; cerei small, subfalcate, slightly upturned but other- 

 wise straight lamellae, tai)ering gently from the base nearly or (luite to 

 the middle, beyond eijual, about two-thirds as broad as the extienie 

 base, api(tally rounded or subtruncate, much shorter than the supra- 

 anal plate; subgenital i>late small, rudely subeonical, terminating in a 

 feeble blunt tubercle.
