Black, the front except each side and an ocellar spot, face cheeks, first two an¬ 
tennal joints, arista, palpi, halteres and legs, yellowish, the bases of the front femora 
and a streak or more or less of the bases of the others, sometimes black; hairs of 
occiput, body and legs long and abundant, principally reddish-yellow, arista bare,

Scatophaga furcata Say. 
This is one of the few species introduced from Europe and described 
m this country before it was described in Europe. The synonymy is : 
squahda Meig., apicalis Curtis, nigricans Macq., fuscinervis Zett., pu- 
bescens Walk., and Cleigastra suisterei Townsend; the latter based upon 
a co-type specimen. 
Opsiomyia, gen. nov. 
Ihe characters of this genus may be gleaned from the following de¬ 
scription of the type species : 
Opsiomyia palpalis, sp. nov. 
Head slightly broader than high, as long as high, slightly longer at base of 
antennae than at the vibrissae, seven pairs of orbital bristles which extend from the 
lowest ocellus to the anterior end of the front, clypeus connate with the face and ex- 
ten ing more than the length of the second antennal joint below the vibriSsae, the 
fitter almost twice as long as any of the adjacent bristles, lateral oral margin bearing 
black bristles on nearly its anterior half; third joint of antenna twice as long 
as broad, slightly more than twice as long as the second, the anterior apical 
angle produce! in the form of a tooth, arista bare, thickened on the basal third, the 
penultimate joint slightly longer than broad; proboscis robust, palpi greatly flattened 
of nearly an equal width but tapering at the base, five times as long as broad, pro¬ 
jecting four-fifths of its length beyond the oral margin, each bearing a single long 
ack bristle near the middle of the outer side, eyes oblique, slightly higher than 
ong, bare. Bristly hairs of body short and sparse, five dorso-central macrochaetae* 
one sternopleural and four stout scutellar, none on the abdomen, all femora and tibise 
earing several, hind tibiae each with two pairs on the outer side besides those near 
the tip. Venation practically as in Cordylura, all veins bare. Black, the extreme
