terior edge rather flattened, posterior edge only slightly convex, 

 corners neatly rounded, thickened rim distinct, narrow; covers 

 with two pairs of fairly long, peripheral bristles; the four median 

 pairs laterad of longitudinal center except the fourth pair which 

 are slightly mediad of center and very close to posterior edge, 

 anterior pair more remote than peripheral, antero-central pair 

 closer to anterior pair than are postero-central pair to posterior 

 pair; sternal bristles fairly long; posterior pair shghtly more re- 

 mote than median pair of peripheral cover bristles; more remote 

 than their distance from margin of genital aperture; middle pair 

 near median ends of apodemata and half way between them, 

 though often nearer apodemata II; anterior pair (gular bristles) 

 slightly more remote than second pair, more approximate than 

 median ends of apodemata. Other bristles as in PL 19, fig. a. 

 Labial bristles quite approximate tectopedia III slender, pos- 

 terior margin emarginate. 



Legs armed with fairly long bristles, those of ventral face of 

 tarsus unusually long; terminated by tri-homohamate ungues, 

 outer hooks longer by reason of their flattened shaves, and less 

 bent at distal half. Tarsi stout cuneate, ventral face with the 

 usual three bristles fairly long, multi-short-ciUate, the proximal 

 inserted less than the diameter of the segment' from proximal 

 end, closer to second than second is to third, followed by a pair 

 of much shorter, ciliate bristles, this pair with a short, smooth 

 bristle inserted closely distad; dorsal face with proximal bristle 

 medium in length, inserted slightly proximad of middle of seg- 

 ment; slightly distad of center are three bristles inserted nearly 

 at same point (!) (a fairly short, a long [longest of tarsi I] and 

 a medium long one), all three on a small swelling of the dorsal 

 face; half way between this trio and the distal end a couple (!) 

 of long (!) to fairly long bristles, inserted side by side, very finely 

 barbed; another fairly long, faintly barbed, inserted quite close 

 to distal end; a stout, barbed, lateral bristle inserted less than 

 diameter of segment from proximal end and near dorsal face (is 

 this really the dorso-proximal?) ; a median bristle inserted on 

 transverse plan of ventro-proximal, medium long; another median, 

 barbed bristle inserted on transverse plane of trio, extends quite 

 half its length above tarsus in Plate 19, figure i. Tibiae almost 

 oblong, i. e., with proximal end only slightly narrower than
