eye there is a stout bristle curved backward ; on either side 

 of the frontal stripe a single row of bristles, of which the 

 two uppermost are stronger than those before them, and are 

 curved backward. The frontal row extends down on the sides 

 of the fece for a short distance beyond the base of the an- 

 tennte and to nearly opposite the uppermost bristle of the 

 facial row ; the proclinate ocellar bristles moderately strong. 

 Antennse wholly black, the third joint but little more than 

 three times the length of the second joint. Face satiny 

 white ; vibrissal bristles situated a little distance above the 

 oral margin ; above them is a row of not very strong bristles 

 extending about midway to the root of the antennae. Sides 

 of the face wholly bare, except for the previously mentioned 

 bristles. Cheeks covered with short, black, bristly hairs, 

 their length equal to about half that of the eyes. Eyes 

 wholly bare. Palpi yellowish. Mesonotum shining blue 

 black, with inconspicuous stripes. Scutellum broadly red- 

 dish on the ai:)ex, the apical pair of bristles small and decus- 

 sate. Abdomen shining blue black, with a broad, variable, 

 white j)ollinose, basal band on the segments ; first and 

 second segments each with a pair of marginal Jbristles ; 

 third segment with a posterior row ; the general covering 

 of the a1)donien is composed of rather stout bristly hairs, 

 which are more abundant, longer and intermixed with finer 

 hairs distally. Legs wholly black, the front femora whitish 

 poUinose behind ; pulvilli much elongated ; the claws elon- 

 gate and slender. Wings grayish hyaline ; third vein with 

 a few short bristles at the very beginning ; angle of the 

 fourth vein without a stump, though with a fold appearing 

 somewhat like one. 



Fe7ncde. — Difiers from the male in the front being wider, 

 in the presence of two proclinate orbital bristles on each 

 side, in the abdomen being less hirsute and in the short 

 claws and pulvilli. Length of male, 10 mm. ; of female, 

 12 mm.
