 internal arm of the left clasper. 



$ . Length 4.6 mm. Head : width .97 mm., vertex .48 mm., length .54

 with reddish, geminate mark on tylus nearly obsolete. Rostrum, length 1.88 

 mm., reaching upon middle of the hind coxae, brownish and tinged with red. 



Antennae : segment L length .4 mm., yellowish, darkened with reddish 

 or brown; II, 1.28 mm., slender, thickened apically and nearly equaling seg- 

 ment I in thickness, the longest exserted hairs nearly equal to three times the 

 greatest thickness of segment, yellowish, the apical one-third black; III, .6

 narrowed ; calli slightly convex, brownish, front margin and somewhat between, 

 line on the hind margin with recurved hook at latero-posterior angle, mark 

 on disk of each which extends toward latero-anterior angle and frequently 

 joins spot at front margin of pronotal disk, black; disk largely fulvous, darker 

 near basal margin where the piceous coloration spreads from the punctures, 

 beset with prominent pale pubescence, hairs longest at lateral margins and an- 

 terior angles ; propleura yellowish, finely punctate : xyphus nearly flat, reddish, 

 pale pubescent. SciiteUuni strongly convex, smooth and shining, margins 

 pubescent, dark brownish black or piceous, basal angles broadly and the apex
