irregnlar rows, three bristles of the posterior row beiug almost of the same size 

 as the bristles of the posterior row of the abdominal tergites. 



Abdomen. — The tergites are exceedingly hairy, there being approximately 

 eight rows of short bristles in front of the posterior row of long ones. On the 

 central segments at least three long bristles of the last row are placed below 

 the stigma, besides a variable number of small ones. Segment II bears on 

 each side one to three apical spines, segments III to VI one spine. The two 

 antepygidial bristles of each side are very stout and rather short and obtuse. 

 The basal sternite has only a ventral pair of bristles, besides numerous exceed- 

 ingly minute hairs. The sternites of segments III to VII bear a postmedian 

 row of long bristles, and in front of this row three or four rows of short ones, 

 there being additional small bristles ventrally in front of these rows. 



Legs. — The hindtibia bears about twenty thin short bristles on the inner surface

between the anterior margin and the central vertical rod. The mid- and hind- 

 femora have one subapical ventral bristle on the inner side, and two or three on the 

 outer side, the row of the outer side being continued forward by four or five small 

 bristles in the female, these additional bristles being slightly more numerous in 

 the male. The bristles along the dorsal edge of the femora are placed far apart, 

 but there are, as a compensation, two irregnlar and incomplete subdorsal rows on 

 the outer surface of the femora. The dorsal bristles of the tibiae are very stout, the 

 outer bristles of these pairs being very blunt, particularly those of the first and 

 second pairs of the male. The outer surface of the tibiae, with the exception of the 

 basal third, is almost evenly studded with bristles, the hindtibia bearing more than 

 thirty bristles on the outer side. The tibiae and tarsi are short as compared with 

 their width. The first foretarsal segment bears four curved bristles on the posterior 

 side which are about as long as the second segment. The first and second segments 

 of the hindtarsns have numerous bristles on the outer surface. The longest apical
