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 
little 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 conspicuously 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
