and terminating in a narrow, slender, small beak; the outer forceps 

 are reduced to small plates but rather noticeable, the front edge of 

 each is developed into two small, hairy prolongations; the penis is 

 thick and strongly chitinized. Legs black; front femora cinereous 

 on outer side, the front tibia of the same length as its tarsus to the 

 base of the claws, although to the naked eye the tarsus looks slightly 

 longer; all the pulvilli much elongated, the front ones most as long 

 as the last three tarsal joints. Wings hyaline, but somewhat infus- 

 cated along the veins anteriorly; fourth vein without perceptible 

 fold at the bend ; third vein with six or eight hairs at base. 



Length from 11.5 to 12.1 mm. 



Female. — Width of front 0.30 of the head width, almost the same 

 as in the male, but widening more uniformly from the vertex; pollen 

 of front yellow, except along the orbit where it is white, which color 

 continues down around the eye below ; the third antennal joint de- 

 cidedly wide toward the apex, twice the width of parafacials ; palpi 

 but little infuscated at base; pulvilli and claws small. 



Length 10.2 mm. 



Described from five males and one female, Washington, D. C, 

 August 15, 1923, on honeydew secreted by large scale insects on 

 tulip tree (Aldrich).

PHOROCERA DIVISA, new speciea. 



Male. — Front 0.29 of the headwidth by micrometer at the narrow- 

 est point; front at parafacials with white but hardly silvery pollen; 

 frontal bristles about nine in the row, the two uppermost strong 

 and reclinate, a slight break between them and the remainder, the 

 lowest extending considerably below the arista. Antennae black, 

 the third joint about four times the second, not perceptibly widened, 

 slightly concave on the front side; arista only a little longer than the 

 third antennal joint, decidedly thickened on the basal half, its penul- 

 timate joint small; facial ridges with strong bristles overlapping 

 the f rontals ; parafacials at narrowest fully as wide as third antennal 

 joint; palpi yellow, slightly infuscated at base; proboscis short and 

 small ; bucca about one-fifth the eye-height ; back of head with bushy, 

 white hair. Thorax cinereous, with the usual four black stripes, 

 when viewed from behind ; posterior dorsocentrals 4 ; anterior dorso- 

 centrals 3 ; sternopleurals 3 ; the sternopleura just before the middle 

 coxae with somewhat bushy, long bristles irregularly placed in 

 several rows, but not so stout as in floridensis^ cubensis, and tachi- 

 nomoides. iScutellum imiformly pollinose, the disk covered with 

 short, stubby, suberect hairs, among which there are no bristles; 

 there are three marginal bristles and a small apical pair, the last
