 and South Carolina). 



Dark greenish brown or black, segments edged with brownish red, feet 

 and antennae red. Moderately robust, anterior segments somewhat 

 attenuate, barely crassate, only the anterior and posterior segments 

 punctate, rest smooth. Vertex smooth, very finely and sparsely punc- 

 tate, punctations not numerous between eyes, sulcus barely continu- 

 ous ; clypeal foveokc 10-12. Antennae moderate, usually reaching 

 the middle of second segment. Eyes indistinct, sub-triangular ; 

 ocelli, 35-45, arranged in 6 or 7 series. Segments, 45-52. First seg- 

 ment with the sides sub-acute, marginate, anterior margin sinuate, 

 smooth, finely punctate ; second segment not much produced beneath. 

 Other segments smooth, not punctate, striae of the anterior segments 

 weak, not much decurved, more so posteriorly. Last segment smooth, 

 finely punctate, pointed, but not passing the anal valves ; anal valves 

 moderately smooth, marginate ; anal scale rounded. Repugnatorial 

 pore large, placed on the anterior part, suture bent. Pairs of feet, 

 84-98, not extending much beyond sides of body, Jlrde : coxae of 

 the third and fourth pairs of feet produced into long appendages. 

 Ventral plate produced into a lobe, as in marginatus, but longer and 

 more slender. Genitalia : inner part of anterior plate higher than
