chamberlin: chilopods from Mexico and west indies. 519 



distally rounded and projecting cephalad of directly mesad; femuroid 

 only vaguely bulging proximad of the tooth. 



Anterior margin of prosternum armed with two pale nodular teeth, 

 one each side of the narrow and shallow sinus, these much closer to 

 each other than either is to the corresponding prehensor. Sides 

 nearly straight, only very slightly converging caudad. Wider than 

 long in ratio 21:19. Nearly 1.4 times longer than greatest length of 

 femuroid. 



Dorsal plates as usual showing in part a median sulcus in addition 

 to the paired ones. 



Prescuta short to very short. 



Anterior spiracles large, vertically subelliptic, somewhat narrower 

 ventrally than dorsally. Decreasing in size caudad and gradually 

 becoming circular, those of the caudal region small as usual. 



Ventral plates with the usual deep median longitudinal sulcus which 

 is deepest when crossed by the weaker transverse sulcus behind 

 middle. 



Last tergite with sides straight, distinctly and considerably converg- 

 ing caudad. Caudal margin straight. Plate much longer than wide 

 (ratio about 19:15). 



Last ventral plate narrow. Sides conspicuously converging caudad, 

 somewhat incurved toward anterior end and excurved toward the 

 caudal. 



Coxopleurae much enlarged and elongate, densel}'^ finely porose as 

 usual. 



Anal legs much longer than the penult; nearly as in cubae. 



Pairs of legs 65. 



Length near 26 mm. 



Locality.— Cuba: Monte Verde (Charles Wright). Type, M. C. Z. 

 1727; one 'specimen. 



Telocricus major, sp. nov. 



Head and anterior portion of dorsum dark ochraceous, with a paler 

 median longitudinal line; becoming yellow caudad. Antennae ochra- 

 ceous. Prosternum chestnut, the prehensors paler, more ochraceous. 

 Venter anteriorly dark ochraceous, caudally becoming yellow like 

 the dorsum. 



Body gradually and conspicuously narrowed caudad from the 

 middle but scarcely at all narrowing cephalad. Body and legs in 

 caudal region densely clothed with fine short hairs, these becoming 

 more and more sparse cephalad. 



Head anteriorly semicircularly rounded; caudal margin wide,
