Male. Front .208 of head (average of five, — 

 .197, .201, .202, .210, .229). Very similar to assidua 

 except in the following particulars: Parafrontals 

 and parafacials very deep golden pollinose, which ex- 

 tends to the front half or more of the bucca; behind 

 the eye is a narrow pollinose border which has a yel- 

 lowish tinge; the pollen of the abdomen noticeably 

 yellow, on the fourth segment deep golden, and ap- 

 parently the ground color of this segment is yellow; 

 both segments of the hypopygium yellow and densely 

 pollinose ; the forceps viewed from behind are moder- 

 ately separated but not divergent, at the tip broadly 

 rounded with a slight angle at the outer edge, which 

 projects backward more than laterally. The forceps 

 are broad and not narrowed toward the tip ; they are 

 yellow except for a narrow space at the apex ; viewed 

 in profile the front side is nearly straight; accessory 

 plate yellow, large, rounded, the margin rather thin; 

 posterior clasper black at tip, straight, erect and ex- 

 cised on the front side at the apex; anterior clasper 

 very stout, yellow except the apical third, which is 

 shining black and tapers suddenly to a slender, 

 straight, sharp point; penis apparently single jointed, 

 yellow except the apex and some of the appendages. 

 The back plate is developed into a prominent, erect 

 lobe on the middle line close to the apex and near its 

 base on each side it extends forward in a conspicuous 

 angle ; the transverse plate attached to the front of the 

 organ near its middle has a very complex form, the 

 principal feature being a pair of thin, curved arms
