the length of the body; articles 28 (rarely 29). Prosternal teeth 

 3+3, the outer one reduced as usual. None of dorsal plates with 

 posterior angles produced (for form see Plate 2, fig. 7). Coxal pores, 

 2, 3, 3, 3. Anal legs short, but longer than antennae, the body 2.6 

 times longer; tibia 5.7 or 5.8 times longer than thick dorsoventrally; 

 first tarsal joint 8 to 9 times as long as thick; second tarsal joint 

 8 times longer than thick. Claw of female gonopods long, slender, and 

 curved; spines rather stout, conical and distally flattened. Length 

 7.5-9.5 mm. 



DESCRIPTION. Dorsum brown, with the posterior segments darker 

 and distinctly reddish. Head brownish red or chestnut, darker caudad 

 of the frontal suture. Antennae light reddish brown, pale distad. 

 Legs yellowish, the more caudal ones becoming brown and tinged, 

 especially the proximal joints, with red. Venter brown, with the first 

 and last segments darker; the prosternum and prehensors similar but 

 tinged with reddish. 



Slender, cir. 8.8 times longer than width of tenth plate; eighth and 

 tenth plates of same width ; body narrowed cephalad from eighth plate 

 but little less than in tivius. Body sparsely clothed with short hairs 

 which are as usual more abundant on legs ; hairs of body rather more 

 numerous than in related species, particularly than in tivius. 



Head subcordate; very slightly longer than wide; roughened by a 

 number of shallow longitudinal furrows. 



Prosternum of nearly same form as mfulvicornis. Teeth 3+3, the 

 outermost reduced as usual. 



Antennae short; 3.2 times longer than head; one third the length 

 of body; composed of 28 or rarely of 29 articles, of which those distad 

 of the long second one are short and moniliform as in the other spe- 

 cies; the third and fourth (or sometimes the fourth alone), seventh 

 and eighth, tenth and eleventh, and thirteenth and fourteenth are 

 reduced as in tivius. 



Dorsal acute mostly with a pair of longitudinal furrows each side 

 of middle which often rises ridge-like between them; in addition other 

 smaller and more shallow, irregular furrows or sulci may be detected; 

 furrows limiting the lateral and caudal depressed borders as in related 

 species. Caudal margin of ninth and eleventh plates bowed forwards 

 at ends, the corners of these plates in some appearing obliquely 

 truncate but the line of truncation making but a slight angle with 

 mesal portion of margin; caudal margin of thirteenth plate straight 

 all the way across. 



Ventral plates rugose; a deeper transverse furrow toward caudal
