Coelioxys chicliiineea.— 9 -—Rather slender, shining black; face, 

 clypeus and cheeks covered with a short dense white pubescence, longer on 

 vertex and cheeks beneath; anterior orbits on each side of antennae finely 

 carinate ; pubescence on eyes very short; mesothorax margined all around 

 with short dense pale ochraceous pubescence, on the sides of metathorax the 

 pubescence is long and white, and on the pleura short, having a line of dense 

 white pubescence on anterior and posterior margins; mesothorax with large 

 deep not confluent punctures; in front of tegulse a sharp sinuate transverse

 hind, the lateral teeth long and compressed laterally; tegulse and legs honey- 

 yellow, the latter fringed with snow-white pubescence; wings dusky on apical 

 margin and on upper half of marginal cell; teeth on anterior coxae very short 

 and blunt, outer tip of tibiae with two short acute 

 teeth ; posterior tarsi more or less black, the basal 

 joint dilated and suddenly constricted at base, 

 the lower edge coarsely serrate; abdomen smooth 

 and polished, with fine scattered punctures, more 

 numerous at base of the segments, an oblique im- 

 pressed line on each side of segments 2 — 4, basal margin of the first and apical 

 margin of five basal segments narrowly fringed with dense white pubescence ; 

 first segment entirely and sides of second and third more or less, ferruginous; 

 apical segment (fig. 4) finely and somewhat closely punctured, suddenly con- 

 stricted or pinched before the tip which is obtuse, subcompressed laterally 

 and having a few erect black hairs; venter bright ferruginous, polished, 

 sparsely punctured, apical margin of the segments narrowly fringed with 

 a dense snow-white pubescence; apical segment (fig. .3) black, rather broad,

 carina before tegulse straight, not very conspicuous; tegulee black, polished;
