72 Mr. J. R. Malloch on Haotic Muscaride. 
Genus MertopromyIa, nov. 
Generic characters.—Related to Helina, R.-D. Differs in 
having the pteropleura hairy, and the ventral surface of the 
scutellum with fine sparse hairs as in Anthomyiine. ‘The 
hind tibia has no ecalear, but there are one or two short 
bristles on the postero-dorsal surface. The wing-veins are 
bare and the fourth vein is not curved forward at apex. The 
prosternum and propleura are bare, the prealar bristle 1s 
long, there are no strong presutural acrostichals present, 
the eyes are bare in both sexes, and the frons is as in typical 
species of Helina. 
Genotype, the following species. 
Metopomyia atropunctipes, sp. 0. 
Male and female.—Shining testaceous yellow. Antenne 
brownish, third segment black; palpi brownish yellow, 
fuscous apically. Dorsum of thorax with two faint reddish 
vittze, a small blackish spot above the propleural bristle, and 
a fuscous streak from humeral angle to base of wings which 
extends narrowly on to dorsum and more broadly over 
pleura. First tergite (sec. ver.) with a large fuscous spot on 
each side, third and fourth largely infuscated in male, less 
noticeably so in female. Apices of femora with a broad, 
sharply defined, black band, apices of tibize less deeply in- 
fuscated, their bases more or less browned ; tarsi fuscous. 
Wings clear, extreme base of costa, humeral cross-vein, first 
vein opposite humeral, and the base of third vein brown or 
fuscous. Calyptree and halteres yellowish. 
Male.—Narrowest part of frons about equal in width to 
anterior ocellus, the silvery orbits contiguous at middle; 
parafacial narrower than third antennal segment ; cheek 
fully twice as high as width of third antennal segment ; 
vibrissal angle produced well beyond base of antennee, a few 
setulee above vibrisse ; longest hairs on arista subequal in 
length to width of third antennal segment. Thorax with 
four pairs of postsutural dorso-centrals. Abdomen ovate ; 
sides of first tergite at blackened area with rather dense, 
moderately long, black bristles; fifth sternite with a broad, 
shallow, rounded posterior emargination. Legs slender; 
fore tibia unarmed at middle; fore tarsi slender, longer than 
fore tibiz, basal segment without long, slender, erect, sensory 
hairs ; mid-femur with a series of fine erect hairs on basal 
half or more of postero-ventral surface ; mid-tibia with two
