CHAMBERLIX: CHILOPODS FROM MEXICO AND WEST INDIES. 497 



Spiracles obliquely and mostly narrowly elliptic. 



Anterior tarsi undivided. Tibia with one distal spine, none being 

 present on ventral side. 



Antepenult legs with tarsus undivided; prefemur with two ventral 

 spines and femur with one. The immediately preceding pairs of legs 

 have one spine on femur and prefemur, these becoming bristle like 

 cephalad. 



Penult legs with prefemur bearing along ventral line two slender 

 spines. Femur also bearing two ventral spines in a line, one of these 

 being at distal end; in addition there are on mesal side toward distal 

 end two additional similar spines. The biarticulate tarsus bearing a 

 few long bristles ventrally, mesally, and dorsally, but ectally with 

 numerous shorter and much finer hairs; the more proximal articles 

 with but few bristles. 



Tibia of anal legs unarmed; very much thicker than the tarsus, 

 somewhat clavately widening distad and at ventroectal corner of dis- 

 tal end bearing a conspicuous cylindric process; sparsely "clothed with 

 bristles. First tarsal joint strongly clavately widening from base 

 distad and compressed laterally; extended on ventromesal side at 

 distal end into a conspicuous conical process; clothed with few long 

 stiff bristles; clearly less than half as long as the tibia. Second divi- 

 sion of tarsus abruptly much thinner than the first article is distally, 

 its proximal article about half as long as the first division; articles of 

 distal division, six to eight, clothed sparsely with long bristles like those 

 of the preceding articles. Femur armed along ventromesal line with 

 two small spines, one toward proximal end and one at or a little proxi- 

 mad of the middle; otherwise unarmed; clothed sparsely with 

 bristles. Prefemur with a ventral row of three stout spines which are 

 clearly shorter than the diameter of the article and are distally bent; 

 along median line of mesal surface near middle of length with two 

 spinules and along dorsomesal line with a series of five or six longer 

 acute spinules ; immediately ectad of ventral spines two short spinules 

 and below middle of ectal surface about six longer spinules like those of 

 the dorsomesal line; elsewhere bearing only hairs, which are sparse. 



Length near 19 mm. 



Locality. — Grenada: Richmond Hill (C. T. Brues and G. M. 

 Allen). Type, M. C. Z. 1746; one specimen. 



Newportia cubana, sp. nov.
