than second, more dilated; fourth one-half longer than second. 
Mesonotum shining dark brown. Seutellum and postscutellum 
dark reddish brown. Abdomen yellowish fuscous. Wings hya- 
line, third vein uniting with costa well before apex; fifth obso- 
lescent distad, joining posterior margin at distal fourth, its 
branch at basal third. Halteres translucent whitish basad, fus- 
cous apicad. Coxae dark brown. Legs mostly yellowish brown. 
Claws rather long, evenly curved, slender, pulvilli rudimentary. 
Genitalia: Basal clasp segment moderately long, stout; terminal 
clasp segment rather long, swollen basad, dorsal plate deeply 
and triangularly emarginate, lobes triangular and sparsely 
setose; ventral plate moderately long, broad, broadly rounded 
apicad; style long, stout, and tapering to a narrowly rounded 
apex. 
Female. — Length, 0.75 millimeter. Antennae a little shorter 
than body, rather thickly haired, yellowish brown, of 14 seg- 
ments, fifth with a stem about one-half the length of cylindrical 
basal enlargement, the latter about three times as long as its 
diameter. First segment of palpi short, irregular ; second some- 
what dilated, its length over twice its diameter; third one-half 
longer than second, slenderer; fourth a little longer than third 
and more dilated. Mesonotum dark reddish brown. Scutelium 
yellowish, darker basad. Postscutellum yellowish. Abdomen 
deep red. Halteres yellowish basad, fuscous apicad. Legs 
mostly yellowish fuscous, distal tarsal segments somewhat darker. 
Ovipositor short, lobes with a length two and one-half times 
width and sparsely setose. 
Type. — Cecid. a2883. New York State collection. 
The coloration in this species is evidently variable, another 
male having a shining reddish brown mesonotum, yellowish 
scutelium and postscutellum, and dark reddish abdomen. A 
second female had a shining, very dark brown, almost black 
mesonotum.

A series of midges was reared from copra (dried coconut meat) 
kept in the laboratory for breeding Necrobia rufipes de Geer. 
The glass vessel had not been opened for a month. The charac- 
teristic short stems of the flagellate antennal segments and the 
heavy circumfila lead me to place this species here, though the 
poorly developed pulvilli would indicate an affinity with Silves- 
trina Kieff. or Planodiplosis Kieff., the latter known only by the 
female. It is probable that the larvae are scavengers, as is the 
case with A. aphiphila Felt and some other American species.
