The dorsum is fuscous throughout, without any distinct median 

 paler stripe, though the tergites appear a little darker on the sides 

 than along the middle. The legs are blackish with an indistinct and 

 incomplete paler annulus over middle of femur and tibia and with 

 a vaguer annulus at base of latter on some legs. Articles of antennae 

 very short, much broader than long, first division of flagellum con- 

 sisting of 79 articles. Head deeply depressed over posterior median 

 region, the depression somewhat furcate between eyes. A shallower 

 median longitudinal furrow on anterior part of head. The stoma- 

 bearing tergites notched or incurved at middle behind, the stoma 

 slightly projecting caudad. Stoma saddles moderately elevated, the 

 stomata of moderate length, on caudal slope of saddles. Last ter- 

 gite with caudal margin flattened at middle, but not at all excised. 

 Dorsal surface bearing numerous short, slender spines or spiniform 

 setae, all unaccompanied by finer hairs. The slender spines numer- 

 ous on margins, more sparse over the general surface. 



The body of the type is injured at the caudal end, so that the geni- 

 tal forceps cannot be described. 



First division of tarsus I composed of 14 articles, the second of 

 32. First tarsus of seventh legs with 10 articles, the second with 30. 

 First tarsus unspined distally. Second tarsus of anterior legs with 

 pegs beneath in typical manner. Spines present at distal end of 

 tarsus I in median and posterior legs.
