(1) Syneches testaceus, nov.sp. — Female. Length 5.5mm, Resembling rwfws Loew, but the marginal 
cell not widened at the stigma.  Entirely testaceous, including the antennz, mouthparts, halteres and legs, but the tarsi 
flavous and the last two segments of the abdomen fuscous, stigma strongly brown, elliptical, nearly filling out the end of 
the marginalcell. Mesonotum covered with yellow tomentum but when viewed from above appearing subshining, meso- 
pleure shining. Hind femora spinose beneath. Wings hyaline, veins strong and brown, marginal cell rather "— 
pointed, at the stigma not much wider than the submarginal cell. 
One specimen : Kansas City, Missouri, June, received from F. Rogers. 
(2) Syneches varus, nov. sp. — Male. Length4.5mm. Occiput black, lightly brown pollinose except above 
neck ; basal joints of antennz yellow, third joint blackisb, the subdorsal brown arista three times antennal length ; mouth- 
parts yellowish. Mesonotum testaceous, lightly coated with yellow dust, nearly bare of hairs, bristles black, two scutellars 
and ten fine marginal hairs ; upper pleurz light brown, lower yellow, Second abdominal segment testaceous, third piceous, 
remainder black, shining, hairs pale, genitalia rather small and forcipate, its hairs blackish, venter yellowish becoming 
brown posteriorly, Coxe brown, femora black, the anterior knees lighter, anterior tibiz and tarsi yellow, hind tibiae 
brown at base remainder black, tarsi yellowish, the long seta at basal two-fifths of front tibize very thin, the long setze near 
middle and apex of middle tibiae not excessive ; hind femora stout, the outer lower face with ten stout spines, of which the 
distal six arise from distinct tubercles, four smaller spines on inner lower face ; hind tibiz strongly curved, with two 
denticles at two-fifths and three-fourths their extent. Knob of halteres piceous. Wings narrow, hyaline, apex lightly 
infumated, veins brown, stigma fuliginous, detached from the gently curving second vein and abruptly cut off within, 
third and fourth veins parallel, discal cell moderate, the sections of fifth vein 1 : o.8. 
Holotype, Mt. Makling, Luzon, Philippine Islands, C. F. Baker, collector. The parallel-sided apical cell excludes 
this species from Harpamerus.
