One male, labeled " Winthem Coll." ; has three labels of " leu- 

 cophrys," one Yerj old. The word " type " does not occur on any. The 

 specimen is in fine preservation and one would hardly think it could 

 have ever been seen by Wiedemann ; it does not look old enough and 

 the pin looks modern. (It has not been repinned.) However, being 

 from Brazil and agreeing exactly with the Wiedemann description, 

 it is undoubtedly authentically determined. 



Width of front 0.25 of head by micrometer. Ocellars proclinate, 

 parallel, not very large, one broken off. Frontals 2 reclinate, about 

 11 decussate, some small, just outside middle of row, inclined mesaily. 

 Lowest frontal at level of tips of second antennal joints, below it 

 only 2-3 very minute hairs. Paraf rontal lead colored, densely poUi- 

 nose; paraf acial pure white, not silvery; transverse impression and 

 lower posterior orbit the same ; cheek with black hairs nearly to eye 

 and covered with very dense long white pollen, the little white scales 

 suberect and distinct under high power. Antennae black, the third 

 joint a little more than twice the second, moderately slender, not 

 reaching vibrissae; arista rather long, evenly tapering, basal joint 

 short. Palpi yellow at least on apical half. Back of head white 

 poUinose and pilose with one row black above and 2-3 below. One 

 pair of verticals, not decussate, reclinate. Facial ridges with coarse 

 erect bristles not quite to the level of lowest frontal. 



Thorax thinly slaty or plumbeous above to scutelhim, the latter 

 brown. A fine brown line each side halfway between acrj)sticlial and 

 dorsocentral, also an interrupted short line outs'de dorsocentral. 

 Chactotaxy: humeral, 3; posthumeral, 2; acrostichal, 3, 3; dorso- 

 central, 3, 4; notopleural, 2 (hairy around them); siipraalar, 3; 

 intraalar, 3; postalar, 2; scutellum with 4 long marginals each side 

 curved down, one widely separated discal also curved down ; disk 

 spiny, less so in front, one pair slanting spines almost apical in 

 position.
