-ART. 7. CENTIPEDS OF CENTBAL AMERICA — CHAMBERLIN. 15 



a much reduced setae each side of the first of these. Median piece 

 of labrum i3rojecting well caudad of the lateral pieces ; bearing typ- 

 ically six long teeth (pi. 4, fig. 4). Coxal plate of first maxillae 

 with a pair of long setae at anterior border, and three or four lessee- 

 setae. Setae of coxae of second maxillae few, consisting typically 

 of a submarginal series of four on each side and a group of four at 

 middle. For other features see plate 3, figure 4. Exposed part of 

 basal plate about four times as broad as long. (In the holotype the 

 cephalic plate has been shifted abnormally forward.) Claws of pre- 

 hensors when closed extending beyond distal end of first antennal 

 article, but not attaining the distal end of the second. Tooth at base 

 of claw black, conical, that of the femuroid similar but larger. Teeth 

 of prosternum short, blunt. See further plate 3, figure 2. Dorsal 

 plates distinctly bisulcate, the paired sulci also traversing the basal 

 plate. ^Vnterior ventral plates w^ith a deep, median longitudinal 

 sulcus. First spiracle large, vertically oval, the second of similar 

 shape and but little smaller. The third more abruptly reduced, the 

 succeeding ones soon becoming circular and small. Last dorsal plate 

 narrow and long, its sides nearly parallel (pi. 2, fig. 5). Last ven- 

 tral plate very narrow, its sides a little converging caudad, toward 

 caudal end rounding in to caudal margin. Coxopleural pores small 

 and very numerous ventrally, laterally, and dorsally (pi. 3, fig. 3). 

 Pairs of legs, 69 to 71.

Resembling S. stolli (Pocock) in general. Frontal plate not dis- 

 crete, but vaguely indicated in part only as a pale line. Head 

 widest near level of this line, the sides moderately converging caudad 

 instead of being parallel. The anterior corners are not widely 

 rounded, as represented in the figure of S. stolli, but are a little 

 obtusely angular, the anterior margin of the head being in the form 

 of a very obtuse angle. The length of the exposed portion of the 

 basal plate is much less than half its anterior width, being over- 

 lapped by head and by first tergite; it bears a single transverse 

 series of setae. It differs from stolli, according to notes on the 

 latter given by Attems,^ in having two small clypeal areas, each 

 bearing a seta instead of a single nonsetigerous area. In front 

 of the two setae of these areas in the present species is a second pair
