The mottled brown male was taken June 11, 1906 on Mayapple, 
Bodophyllum peltatum, at Albany, N. Y. It was 
wept from sugar maple, Acer saccharum, and white pine, 
Pinus strobus. In general color characters this species 
grees very well with Diplosis maccus Loew 1 and may 
prove to be a synonym. The antennal coloration is also similar to 
mat of Cecidomyia atricornis Walsh.

thickly haired, alternately yellowish and reddish, the larger 
snlargement of the segments lighter, the smaller and the distal portion 
of the stem darker; 14 segments, the fifth with stems two and two 
and one-half times their diameters, respectively. Palpi; the first 
segment subquadrate, swollen distally, the second more than twice 
the length of the first, narrowly rectangular, the third a little longer,

margin and also a subapical yellowish area; there are three indistinct 
yellowish areas between the third vein and the fifth, the first just 
beyond the middle, the second near the apical fourth and the third 
subapically; another yellowish area lies on the posterior margin just 
behind the fifth vein, and one near the anal angle close to its branch; 
halteres and coxae yellowish transparent, femora pale yellowish
