By J. M. Aldrich 



Of the Smithsonian Institution, Washington, D. C. 



Genus B00P0NTJS 1 novum 



Female only. — Eye rather small, bucca (below) equal to half 

 its height; front one-third of head width, the median stripe 

 occupying two-thirds its width. Ocellar bristles well developed, 

 strongly divergent; verticals two pairs, the inner convergent. 

 Frontal bristles about fourteen in the row, reaching the middle 

 of second antennal joint, the uppermost one diverging strongly 

 to the side, the next just as strongly to the middle, and the 

 following ones like it but gradually more erect. Interfrontals 

 absent. Two small orbitals placed high up, opposite second and 

 third frontals. Outside the frontals a uniform covering of 

 small black hairs, which extend downward covering the para- 

 facials and bucca except a small space outside of and above the 

 vibrissas. Facial ridges with larger hairs nearly halfway up. 

 Vibrissas hardly more than half as far apart as the facial ridges 

 at their middle. Face much depressed, the ridges high and 

 sharp. Antennas of ordinary form, not large. Arista strongly 

 thickened on basal two-fifths, penultimate joint short, bare below, 

 pectinate above with short hairs which at longest are hardly 

 double the thickness of the arista. Palpi normal; proboscis 

 short, with ordinary labella. 



Thorax with a row of half a dozen hypopleural bristles; 

 sternopleurals, 2; acrostichals, 2 or 3 anterior, 3 posterior; 

 dorsocentrals, 2, 3 ; humerals, 3 ; interhumerals, 1 ; posthumerals, 

 2; presuturals, 2; notopleurals, 2; intra-alars, 3; supra-alars, 2; 

 postalars, 2 ; scutellars, 4 pairs lateral in a straight row of which 

 the last and largest is apical, and 3 or 4 pairs above them which 

 become subdiscal toward the tip. Hind calypter bare, twice as 

 wide as front one. Pteropleura with hairs and a very small 

 bristle. 



Abdomen without macrochsetae, covered with uniform black 

 hairs like those on the head; hind edge of all four segments
