CHAMBERLIN : CHILOPODS FROM MEXICO AND WEST INDIES. 517 



greater proportionate length of antennae and anal legs is readily 

 noted in most cases. 



Telocricus cubae, sp. nov. 



Anteriorly ochraceous, becoming clearer yellow caudad. Head 

 darker, of very dilute chestnut cast. Antennae yellow. Prosternum 

 and prehensors like head. 



Body of nearly uniform width from middle forwards to head but 

 conspicuously narrowing caudad. 



Cephalic plate with anterior margin subtruncate; caudal margin 

 straight. Head of nearly uniform width from frontal region to 

 rounded caudal corners, the sides being straight. Frontal plate 

 coalesced but line of union indicated by a faint pale line. Head 1.67 

 times longer than wide (ratio cir. 92:55). Basal plate three times 

 wider than length at middle. 



Antennae long, 3.25 times longer than the head. Rather thick. 

 Articles long; the ultimate only about two thirds as long as the two 

 preceding ones taken together. 



Claws of prehensors when closed reaching to distal end of second 

 antennal article. Claw armed at base with a stout black tooth. 

 Intermediate articles unarmed. Femuroid with- a stout, distally 

 truncate black tooth toward distal end, the tooth larger than that of 

 the claw; femuroid somewhat protruding midway between tooth 

 and proximal end. 



Prosternum with two short, bluntly rounded, well-chitinized teeth 

 on anterior margin, one each side of the narrow, shallow, median 

 sinus. Sides nearly straight, very slightly converging caudad. A 

 Httle wider than long, the ratio being about 19:18; 1.63 times longer 

 than the greatest length of femuroid. No trace of chitinous lines. 



Dorsal plates deeply bisulcate. A conspicuoush^ impressed median 

 longitudinal sulcus also evident on the anterior plates especially. On 

 most plates a strongly impressed transverse sulcus a little in front of 

 the caudal margin. Hairs very short, sparse. 



Anterior prescuta very short, gradually increasing caudad, but still 

 short in caudal region. 



Anterior spiracles very large, vertically subovate, gradually assum- 

 ing the circular form caudad. First spiracle much the largest, the 

 others gradually decreasing in size caudad, the most posterior ones 

 being very small. 



Ventral plates marked with a strong median longitudinal sulcus 

 which is crossed between middle and caudal margin by a weaker 

 transverse sulcus, impression deepest at point of crossing. On the 

 anterior plates the median sulcus bifurcates widely cephalad, in a
