10 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 89 



Pocock's description states that the head is " apparently furnished 

 on each side with two large, black, prominent eyes, the upper of which 

 are covered by, though visible through, the first tergite." In none of 

 the specimens I have examined, several of which have been dissected, 

 has there been more than one eye on each side, although the surface 

 behind the eye, beneath the first segment, is sometimes dark-colored. 



The dorsum of the segments has two transverse rows of short, rather 

 widely spaced, erect setae ; one row crossing the middle of the sub- 

 segment, the other in its posterior margin. First segment with setae 

 more numerous and scattered over the entire surface.
