CHAMBERLl.N : THE CHILOPODA OF BRAZIL. 185 



CUPIPES .^AlAZONAE, Sp. nOV. 



Dorsum olive or oli\e-broAvn; most of the plates of the middle and 

 anterior regions of body with a blackish spot or short stripe at each 

 lateral margin; in the plates of the median region also a dark spot on 

 caudal border at caudal end of each sulcus or the two spots may be 

 united as a transverse band. Head darker, more brownish and dusky. 

 Antennae bright green. Prosternum and prehensorial feet clear 

 brown, the latter rufous laterally and especially distally proximad of 

 the black claw proper. 



Head clearly longer than wide (46:41). Sides a little convex just 

 behind the eyes and then substraight and a little converging to the 

 caudal corners. Finely and uniformly subdensely punctate. The two 

 di^■erging longitudinal sulci reaching or very nearly reaching the 

 anterior margin, each terminating in a transverse sulcus slightly 

 removed from the edge of antennal socket with which it runs parallel. 



Antennae composed of seventeen articles of which the first seven 

 are glabrous or practically so and in this respect sharply separated 

 from the more distal group. 



Prosternum with two sharply defined longitudinal sulci converging 

 cephalad and uniting at an angle at anterior end; these sulci crossed 

 by a transverse sulcus which is branched and has anastamoses as 

 shown in Plate 3, fig. 5. Dental plate without true teeth, but bearing 

 an elongate ectal process with on mesal side at base a low, dark, denti- 

 form elevation (Plate 3, fig. 5); on one side the plate is malformed 

 as shown in the figure, this probably being due to injury with imper- 

 fect subsequent regeneration. 



IMargination of the dorsal plates indicated from about the seventh 

 caudad but not very distinctly until the tenth. Plates with an obscure 

 low median keel defined by two indistinct longitudinal furrows; also 

 a vague furrow laterad of each median sulcus may be indicated. Last 

 dorsal plate with a sharply impressed median longitudinal sulcus. 



Second to twentieth ventral plates with the usual two longitudinal 

 sulci crossing the plate. A rather vague transverse furrow may be 

 traced at the level of the legs; while on some plates indications of a 

 verv weak median longitudinal furrow mav be detected. Last ven- 

 tral plate clearly wider at its anterior end than long (2.6:2). Sides 

 strongly converging caudad; plate truncate caudad, the corners a 

 little rounded. \Yithout a median sulcus or furrow. (Plate 2, fig. 9). 



Coxopleurae with a short but distinct process at mesocaudal corner,
