hortest, and are frequently somewhat retracted within each other, 
he terminal segment of the body is bent abruptly downward 
eyond the middle find constricted before the tip. The body is soft 
nd flexible, and the movements of the maggot are sluggish. 
The head, viewed from above, is broad-ovate in outline, narrow- 
lg forwards, and somewhat abruptly rounded in front. It is smooth 
i ad shining, about as long as the first segment, within which it is 
•equently more or less retracted. Its width is about three-fourths 
s length. The entire larva is one-third of an inch in length when 
ill-grown, and about one-fortieth of an inch in transverse diameter • 
ad of nearly uniform size throughout, only the first two or three 
igments being slightly narrower than those succeeding them. It is 
larked with neither hairs nor punctures, and provided with no 
vomotor structures whatever. The shape and proportions of the 
ifierent segments of the body are sufficiently shown by the cut. 
The larvae of this family differ from those of most diptera, not 
ily in having a well defined head, but also in having a somewhat 
implicated mouth apparatus, which consists in this larva of a 
brum, two mandibles and two maxillae, with a rudimentary struc- 
ire possibly representing the labium. The labrum (Plate IY, Figs, 
and 9,) is a thick, fleshy organ attached to the front of the head 
xmt half as long as wide, deeply emarginate in the middle, the 
teral lobes formed by this emargination being broadly and regu- 
rly rounded. The base of the labrum is firmly supported by a 
jarly complete black, chitinous ring. The mandibles (Fig. 7) are 
ladrate in form, entire, except the terminal extremity, which is 
vided into four obtuse lobes or teeth, the two inner of‘which pro- 
angles to the others. This toothed extremity of the 
andibles is yellowish-brown, the remainder black. The maxilla 
ig. 6) are composed of three parts, a subtriangular, basal part 
ae stipes), and a larger, terminal part composed of two pieces, the 
ner of which is oval, and provided at its margin with about six or 
ven large, obtuse teeth, the proximal ones of which are largest, 
i le outer part is oblong in outline, as long as the inner, and bears 
>on the under surface, near the tip, a circular, membranous area, 
mi which springs a minute, inarticulate palpus. 
If further observations should chance to show that this larva may 
come_ injurious, it should not be difficult of destruction. Probably 
simple burning of the grass preparatory-to breaking up the sod 
[mid be sufficient.
