Insctosa Coquillett. 
Caenia fumosa Sten. 
This is a European species, and so far as I can find has not 
been reported from this country heretofore. The seven specimens 
before me, taken at Castalia, Ohio, July 13, 1901, agree so well 
with the description of fumosa given by Schiner, and are so 
readily traced to this species by Becker’s key, that I do not 
hesitate to identify them as such. 
Caenia virida n. sp. 
General color dark green, thinly yellowish and gra}- pruinose. Antennae 
clear brown, arista rather long pectinate above on median third, hairy on 
basal part, proboscis dark nearly black, face and cheeks rather densely yel- 
lowish pruinose except on upper part where the green ground color is dis- 
tinct, clothed with rather short black hairs, bristles of the oral border 
distinct ; front green shining, with two pairs of orbital bristles, dorsum of 
thorax green, thinh' yellowish pruinose and with five pairs of dorsocentral 
bristles, pruinositj- of the pleura dense obscuring the ground color, scutellum 
green shining with two pairs of bristles, legs black except the knees which 
are narrowly but plain!}- red, wings uniformly grayish hyaline, veins brown, 
halteres yellow ; abdomen shining green thinly gray pruinose, a middor.sal 
row of bronze triangles on segments three to five and suggestions of bronze 
on the anterior margins of the sides of the same segments, two to four nearly 
equal in length, five much longer. Length 6 millimeters.
