ORTALID^E — EUXESTA. 161 



Head dark-yellow ; front rather broad, with a very narrow 

 border of white pollen ; the hairs upon the front are not con- 

 spicuous. The stripes descending from the vertex along the sides 

 of the front and the immediate surroundings of the ocelli are 

 steel-bluish, somewhat shining. Antennae dark-yellow; their 

 third joint rather round. Face rather excavated, with a white 

 pollen which is less dense in the vicinity of the anterior border 

 of the mouth, and from under which a faint steel-blue reflection is 

 still visible. Clypeus but moderately projecting over the anterior 

 edge of the mouth, generally of a dark-yellow color, seldom with 

 a faint trace of a steel-blue reflection. The upper portion of the 

 occiput, with the exception of a large spot behind the vertex, is 

 steel-blue, with a whitish pollen. Thorax steel-bluish, with a 

 rather whitish pollen and hence but moderately shining. Scutel- 

 lum, metathorax and abdomen bright, shining, almost metallic 

 black ; the sides of the first and second segments of the abdo- 

 men have a yellow coloring, which, however, usually does not 

 reach the posterior margin of these segments and sometimes is 

 more expanded in the middle. Front coxae and femora dark- 

 yellow ; tibiae, with the exception of the extreme basis, and the 

 tarsi brownish-black. Halteres whitish with a dirty-brownish 

 stem. Wings hyaline ; immediately beyond the humeral cross- 

 vein there is a small black spot, which extends, in the shape of a 

 crossband, as far as the root of the anal cell ; the rather long 

 stigma is black ; from its basis a black crossband extends in a 

 somewhat oblique direction as far as the middle of the discal cell ; 

 immediately before the apex of the wing, another black perpendicu- 

 lar crossband is situated ; anteriorly it is somewhat widened, poste- 

 riorly it crosses the fourth longitudinal vein , the last section of 

 the fourth longitudinal vein is moderately but distinctly curved, 

 and converges with the third longitudinal more in its latter half 

 than in its first. The intervals between the black crossbands of 

 the wings of this species, as in most of the others, by transmitted 

 light assume a rather indistinct white coloring, in a similar light, 

 however, the apex of the wings of this species assumes a very 

 striking whitish coloring.
