the third thickened at the base, rather short, and sub-pubescent ; 

 epistome prominent ; proboscis long, slender, and porrected ; abdomen 

 oblong and elliptical, armed with seta) on the disc of the segments ; 

 wings with the first posterior cells very slightly open at the apex, and 

 often quite closed or even stalked. This genus is rather aberrant, 

 and from the structure of the wing it might be placed in the second 

 division of my analytical table.

Cheeks and sides of frontalia silvery-white, with black reflections ; antennae and 

 palpi black ; thorax grey, with four black stripes, the central pair narrow, the outer 

 ones broad ; abdomen black, the rings with narrow white bands on their front edges, 

 and having the sides of the three first ones dark red ; wings greyish, with the roots,

Oen. ch. — This small genus contains one or two shiny black 

 bristly species, resembling some of those in Macquartia in general 

 appearance, but differing by being more setose, and having the eyes 

 widely and nearly equally separated in both sexes. The eyes are 

 thinly but rather longly haired in the males, and almost nude in the 

 females ; the fronto-orbital bristles are in a double row on each side 

 towards the vertex in both males and females ; the antennae are 

 drooping, with the second joint rather long, but nearly one-half shorter 

 than the third ; the arista is rather short and thickened at the base ; 

 the abdomen is conico-cylindrical, with setae on both the middle and 

 edges of the rings, the anal segments in the male are rather large and 

 incurved ; the wings have large costal spines, and the angle at the 

 base of the apical cross veins somewhat rounded ; the legs are very 

 spinose.

 This is rather a peculiar-looking fly, having a shining black body with bright 

 reddish-yellow scales and basal halves of the wings ; the forehead is prominent ; the 

 antennae black, with a red tinge at the end of the second joint ; the palpi have the 

 bases dark, and the ends reddish-yellow ;* the thorax, like the abdomen, is immacu- 

 late, has a little white pubesoence on the front edge, and numerous strong bristles on

 generally described as being black ; are these belonging to lsls.c(i\x&rt'afiavipalpu ?
