dorsally at distal end with two stouter short spines or teeth of which

 teeth. First tarsal joint bearing a ventral series of three, five stout 

 teeth, followed by a small rounded process or lobe at distal end to- 

 ward mesal side.

SCOLOPENDRIDAE. 



Scolopendra polymorphs pueblae, var. nov. 



Differs from typical S. polymorpha most clearly in having the 

 distal process of the prefemur of the anal legs bearing uniformly only 

 two stout spines (or in one specimen three on one side only). Spines 

 of coxopleural processes three to five, of which one or two are stouter 

 than the others, and one lateral one on the caudal edge of the coxo- 

 pleura. Median sulcus of last dorsal plate fine, distinct. Dorsal 

 plates sulcate from the tenth on. Tarsus of twentieth legs armed. 

 Olive-brown with caudal borders of plates deeper green. 



Length from 130 to 135 mm., much exceeding the average of the 

 forma typica and the larger one exceeding the maximum length re- 

 corded for the species. 



Locality. — Mexico: Puebla (Mrs. L. C. Langton). Type, 

 M. C. Z.1705; two specimens. Type and M. C. Z. 1748.
