PHOROCERA SPECULARIS, new species. 



One of the three species of this genus in which the parafacials 

 are bristly below the frontals and readily separated from the others 

 by the dark reflecting spot below each of the lowest frontal bristles. 



Front of male 0.290 and in the female 0.333—0.366 of the head 

 width, gray pruinose with a yellowish cast, subshining in the male, 

 less so in the female ; vertex somewhat blackish ; sides of face below 

 the lowest frontals bristly for some distance, the parafacials silvery 

 with a dark reflecting spot; bucca about one-third the eye height, 

 in some specimens slightly more; palpi yellow; antennae black, 

 nearly as long as the face, the third joint in male five and in the 

 female four times the length of the second; arista thickened on 

 the basal third, the penultimate joint short. Thorax black, gray 

 pollinose, marked with four black vittae; four dorsocentrals ; scu- 

 tellum black, gray pollinose, often yellowish at tip, bearing three 

 long lateral and one shorter cruciate apical pair of bristles; there 

 are also a widely separated pair on the disk. Sternopleura with three 

 bristles. Abdomen thickened, black, subshining, the base and sides of 

 each segment but the first gray pollinose ; venter wholly gray polli- 

 nose. One pair of median marginal macrochaetae on the first seg- 

 ment, second with one pair median discal and marginal, the third 

 with one pair discal and a marginal row, the fourth with two rows of 

 macrochaetae on the apical half and at the apex of segment ; abdom- 

 inal hairs erect and conspicuous, especially so in the male. Legs 

 blackish, mid tibiae with two or more bristles on the outer side near 

 the middle; hind tibiae not ciliate. Wings hyaline, the anterior 

 crossvein strongly infuscated; apical cell open, the third vein bear- 

 ing two or three bristles at base. 



Length 8 to 10 mm.

fPltorocera leucaniae Tothill, Cauad. Ent., vol. 45, 1913, p. 73. 

 Front of male 0.236 and in the female 0.292 the head width;

 much shorter than the frontal bristles which extend below the arista ;

 fifths of the way to the antennae; bucca at least one-third the eye 

 height; palpi yellow; antennae brown, shorter than face, in most 

 specimens reaching two-thirds of the way to the vibrissae, third
