fulvous brown ; and the breast is of the same color, instead of light 
yellow as in the tritici. The last joints of the feet, moreover, are 
commonly though not invariably black in this species, and there is 
often a broad black band at the base of the anterior tarsi. 
The males have the antennz composed of twenty-four joints, each 
encircled as usual with a row of hairs. These joints approach a 
globular form, but have, in common with those of the males of 
several other of our species, this striking peculiarity, namely, that 
through the whole series, though preserving the same diameter, 
they are alternately shorter and longer ; twelve being compressed- 
globular or double-convex, and between each of these a very short 
cylindrical joint with convex ends. 
This species is closely related to the ornata of Say (Appendix to 
Long’s Expedition, p. 357), but is readily distinguished from that 
by its blackish antenne, the color of which contrasts strongly with 
that of the legs ; by the greater number of spots on its wings, and 
these spots not being ‘‘occasioned by the greater density of the hair 
of the surface in those parts.” In the latter character it also differs 
from the pictipennis of Meigen, as described by Macquart; as also 
in not having the spots forming bands across the wings. If any 
description of the maculipennis of Stephens, in his catalogue of 
British insects, has ever been published, I have not met with it. 
That this species, however, exists abroad, is highly probable, from 
the fact that the specimens reared from wheat-worms by Mr. Mark- 
wick had ‘spotted and transparent wings,” as he describes them, 
or “obsolete clouds” as they were termed by Mr. Marsham. Mr. 
Curtis calls attention to this fact respecting these specimens, ap- 
parently from a suspicion thus excited that another species existed. 
He says, “I am particular in noticing this, because the wings of 
Mr. Kirby’s C. tritici are not spotted, nor are any individuals that 
I have seen; and excepting the C. pictipennis, which is larger, I 
know of no species of the genus with spotted wings.” 
The species under consideration, may appropriately be named 
and characterized as follows : 
Cecidomyia caliptera, Orange-red ; base of the tergum blackish : 
wings hyaline, with seven dusky spots: legs whitish; tarsi black at tips, 
Length 0°05.
