 Scatophaga vulpina, sp. nov. 



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, 

 humeral and dorso central bristles except the posterior pair, very slender, scarcely 

 distinguishable from ihe hairs, pteropleura bare, middle and hind femora destitute of

 Museum. 



Scatophaga furcata Say. 



This is one of the few species introduced from Europe and described 

 in this country before it was described in Europe. The synonymy is : 

 squalida Meig., apicalis Curtis, nigricatis Macq., fuscinervis Zett., pu- 

 bescens Walk., and Cleigastra suisterei Townsend ; the latter based upon 

 a co- type specimen. 



Opsiomyia, gen. nov. 



The 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- 

 tending more than the length of the second antennal joint below the vibrissae, the 

 latter almost twice as long as any of the adjacent bristles, lateral oral margin bearing 

 black bristles on nearly its anterior half; third joint of antennae twice as long 

 as broad, slightly more than twice as long as the second, the anterior apical 

 angle produce J 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, 

 black bristle near the middle of the outer side, eyes oblique, slightly higher than 

 long, 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 tibiae 

 bearing several, hind tibiae each with two pairs on the outer side besides those near 

 the tip. Venation practically as in Cotdylura, all veins bare. Black, the extreme
