ART. 23 FLIES OF THE FAMILT SAPROMYZIDAE — MALLOCH 9 



FREYIA NIGKITA, new species 



Female. — Glossy black, convex upper portion of face brownish 

 yellow, third antenna! segment at insertion of arista, and base of 

 latter, yellow ; artista apically, and its hairs, white ; fore legs with the 

 trochanters, basal two-thirds of femora, and extreme bases of tibia, 

 yellow; mid and hind tibiae and trasi yellow, apices of the tibiae 

 black. Wings yellowish, slightly darker at bases. Knobs of halteres 

 black. 



Head in profile as Figure 5; frons uniform in texture, anterior 

 orbitals slightly incurved, almost as long as, but much finer than, 

 posterior pair; basal and second antennal segments equal in length, 

 the former not haired below ; hairs on arista rather dense, and about 

 half as long as width of third antennal segment ; postverticals rather 

 short ; outer verticals about half as long as inner pair. Surface hairs 

 on mesonotum sparse and short; anterior 

 sternopleural weak; scutellum slightly flat- 

 tened above, rounded in outline, basal bris- 

 tles shorter than apical pair. Fore legs 

 slightly thickened, the femur with ^-3 

 bristles on apical half of posteroventral 

 surface and no anteroventral comb; all 

 tibiae with preapical dorsal bristle. Inner fig. 5.— head of febyia ni- 



, • 1 Ti j> T -\ 11 grita from side 



cross vein close to middle 01 discal cell, 



outer one at fully its own length from apex of fifth vein ; penultimate 



section of fourth vein less than one-third as long as ultimate. 



Lenerth, 3 mm. exclusive of antennae. 



One female, Higuito, San Mateo, Costa Rica (P. Schild.). 



Type.—Qdit. No. 40879, U.S.N.M. 



Genus HALIDAYJELLA Hendel 



This generic name was proposed by Hendel as a substitute for 

 Calliope Haliday, the latter being preoccupied. 



When my previous papers were written I was uncertain of the 

 characters of Calliope^ and referred the American species flaviceps 

 Loew to the genus. Hendel cites aenea Fallen as the genotype of 

 Halidayella, the sole original species of Calliope, scutellata Meigen, 

 being a synonym of this ; and I have that species, elisae Meigen, and 

 atrocaerulea Becker, before me now. These species have the face 

 entirely glossy black, distinctly convex on upper half, and with a 

 transverse depression at middle, below which it is almost flat or 

 slightly convex; the thorax has three pairs of strong postsutural 

 dorsocentrals and no intra-alar; and the frons is shining, with the 

 orbits broad, and but poorly distinguished from the interfrontalia. 

 In the males of these species there is a dense patch of short black
