14. Geophilus legiferens sp. nov. PI. XXIV, figs. 4, 5, 6. 



Almost of uniform width over the anterior and middle portions, 

 attenuated caudad. 



Pale orange in general color; head and presternum light chestnut; 

 dorsum darkened in mesal region; antennae pale orange; legs pale 

 yellow. 



Antennae moderate in length ; the articles gradually decreasing in 

 length distad, the ultimate apically rounded and clearly shorter than 

 the two preceding taken together. 



Cephalic plate longer than wide in the ratio of 4:."). Anterior and 

 posterior margins substraight or but little excurved, the former slightly 

 and widelv emarginate between bases of antennae. Anterior portion 

 of sides rounded cephalo-mesad from frontal suture. Sides from a lit- 

 tle back of ends of frontal suture sub-straight, slight!}- converging and 

 posteriorly rounding inward to caudal margin. Front 1 plate discrete. 

 Prebasal plate not exposed. Basal plate a little less than three times 

 wider than the median length. 



Claws of prehensorial feet when closed reaching the front margin 

 of the head. Claws obscurely dentate at base, other joints unarmed. 



Anterior prescuta short, becoming moderately long in the middle 

 region and intermediate in size in the posterior portion. 



Anterior spiracle large, vertically widely elliptical, others circular, 

 the second intermediate in size, gradually decreasing in size from the 

 third caudad. 



First legs shorter and decidedly more slender than the second. 

 Ultimate legs very long, slender, armed with a large claw. 



Sterna uniformly punctate. Ventral pores on anterior sterna few, 

 in a small median patch just in front of the posterior margin. Anter- 

 ior sterna mcsally widely depressed, marked with a longitudinal 

 median sulcus. 



Last ventral plate long, moderate anteriorly, narrowing decidedly 

 caudad, the sides weakly excurved. Posterior margin of plate straight.
