ART. 23 FLIES OF THE FAMILY SAPEOMYZIDAE — MALLOCH 17 



MINETTIA VERTICALIS, new species 



Female. — General color and habitus similar to the last preceding 

 species, but the femora and tibiae are darker than the tarsi, the frons 

 is only about 1.5 as long as wide, the antennae are comparatively- 

 smaller, the face more noticeably convex below, and the arista is bare. 

 A striking feature of the species is the large number of rather strong, 

 moderately long, bristles across the vertex. The outer cross vein of 

 wing is slightly oblique. 



Length, 5 mm. 



One female, Cayenne, French Guiana (W. Schaus). 



Type.— Cfit. No. 40960, U.S.N.M. 



SAPROMYZA SCHWARZI, new species 



Female. — Testaceous yellow, shining. Frons with a broad brown 

 central vitta which is fully one-third of the width of frons and is 

 bifid in front; antennae brownish fuscous, third segment yellow at 

 base ; face with a brown spot in centre of lower margin ; palpi fuscous. 

 Thoracic dorsum with four conspicuous dark brown vittae, the sub- 

 median pair the narrower and continued to beyond middle of scutel- 

 lum; an oblique vitta of same color on mesopleura and a large spot 

 on upper part of sternopleura. Abdomen in both specimens before 

 me shriveled so that it is impossible to give details of markings, but 

 there are evidences of dark-brown markings on the tergites. Wings 

 clear. Legs testaceous, fuscous on apices of fore and hind femora, 

 most of mid femora, all of fore tibiae and tarsi, and apices of mid 

 and hind tibiae. Halteres yellow. 



Frons subquadrate, of almost uniform texture, shining, and with- 

 out fine hairs, anterior orbital farther from eye than posterior and 

 much shorter than it, ocellars rather short, about equal to post- 

 verticals; arista with its longest hairs fully as long as width of third 

 antennal segment. Thorax with two pairs of postsutural dorso- 

 centrals, a pair of prescutellar acrostichals in line with posterior 

 dorsocentrals, four series of intradorsocentral hairs, situated on the 

 sides of the two submedian dark vittae, and only one sternopleural ; 

 scutellum convex. Legs normal, no anteroventral comb on fore 

 femur. Inner cross vein a little beyond middle of discal cell, apical 

 section of fourth vein about three times as long as preapical.
