thirds the length of the body. This streak is of a dark purplish 
red color, frequently black towards its- anterior end, and in one 
instance it was noticed to be black its entire length. All the 
body of the worm outside of this central streak is sometimes 
hyaline, colorless and watery; but more commonly opake white 
clouds are blended with the hyaline, giving the worm a curdled 
or frosted appearance, similar to that of many of the Syrphus 
larvae; or it is wholly of an opake white color. Moreover the 
white coloring sometimes takes on a tinge of red or even becomes 
pale rose colored instead of white. These colors are variable 
and evanescent, the same worm sometimes changing more or less 
from hyaline to white in a short time. One worm was noticed as 
being hyaline and colorless, with the dark purple streak along 
the centre of its body, and on its under side two rows of opake 
white granules, eleven in each row, the three anterior ones in the 
three thoracic segments being smaller. These granules had a 
similar appearance to legs and prolegs inside of the transparent 
skin, and they also strikingly imitated those members in their 
motions as the worm was crawling on wet glass. It merits to bo 
noticed also, that the larva of this species moves in the same 
manner and has the same form as the larva of the wheat midge, 
represented in Plate 2, figure 12, its tip also being four-toothed, 
as shown in figure 14. 
From these larvae a fly was obtained, which I found to be of 
the same species with one which a short time before had come 
directly from a wheat head, in which the pupa had nestled 
between the chaffs of two of the florets, crowding itself upward 
to their summits to give out the fly. The pupa case from which 
this fly had come was 0.08 long, white, subhyaline and glossy 
except on the abdomen, with a pale brown discolored spot on the 
back of the thorax. The leg sheaths were parallel and soldered 
together side by side, the inner pair being but little shorter than 
the outer, whereby only a semicircular notch was formed at their 
tips. Two robust brown bristles projected horizontally outwards, 
one on each side of the back of the thorax, the same as in some 
other species of this genus. 
In tho female, tho head is nearly globular, broader than long, and broadest back of tho 
middle. The antenmn aro black, about half tho length of the body, composed of about twelve 
oints, which aro oblong, contracted in their middles, and separated by short pedicels. Tho 
thorax is blaok above and polished, orango-yellow on tho sidos and beneath, with tho neck 
also yellow, and tho poisors whitish. The abdomen is dusky, with tho sutures yellow, and is 
clothed on tho sides with silvery white hairs. Two oxsertilo points protrude from its tip,
