food of birds (in July, eaten by a catbird), and was not once recognized 
by Dr. Riley’s assistants in their studies of the contents of the stom- 
achs of one hundred and two English sparrows which had eaten insects. 
REMEDIAL MEASURES. 
Until the life history of this species is better known, measures of 
prevention or of remedy can scarcely be intelligently discussed. The 
fact that its injuries to corn occur without apparent reference to the 
crop of the previous year makes it unlikely that the favorite method of 
rotation will serve for the protection of corn against this species. Ac- 
cording to the scattered observations hitherto reported sweet corn seems 
to be much more liable to injury than the field varieties, from which 
fact we may surmise that the time of planting has something to do 
with the intensity of the attack. The vicinity of cucumbers, squashes, 
and other of the commoner food plants of the beetle may, however, ac- 
count for this seeming preference. 
DESCRIPTION. 
The following description of the stages of this insect is copied 
from Professor H. Garman’s article in “Psyche” (Vol. VI. pp. 48, 49). 
Egg—‘Matured ova from ovaries of females are much like "those 
of D. longicornis. They are white, oval, with the surface reticulated 
and sculptured so as to produce numerous hexagonal, pitted areas. Prof. 
Forbes gives the dimensions of the egg of D. longicornis as .025 inch by 
.015 inch. Ova of the spotted species measures a trifle larger, being 
.027 inch in length by .016 inch in diameter.” 
Larva (Plate XIV., Fig. 4 and 5).—‘Body cylindrical, tapering a 
trifle towards the extremities, composed of twelve segments behind the 
head. Skin wrinkled, papillose along the sides, white, sometimes be-_ 
coming yellowish just before pupation. Head dark brown, nearly black 
in some examples, with a few rather strong hairs arising from the sur- 
face; a narrow median longitudinal line of black above, and two pale 
lines which converge from the bases of the antenne, followi ing sutures, 
to meet at the middle line on the posterior part of the head; ventral 
side of head pale medially. No eyes. Antenne of three segments, 
white. Labrum dark brown. Mandibles dark brown, black at tips, with 
four or more blunt denticles. Maxille pale, armed with numerous strong 
spines within. Labium pale. Cervical shield pale brown, with a nar- 
row median longitudinal white line, broadly triangular in shape. 
Jointed legs pale, each with a dark brown chitinous supporting frame- 
work at base; each segment of legs provided with a number of strong 
hairs; a single brown tarsal claw, beside which arises a white, elliptical, 
striated plate slightly longer than the claw. Dorsal shield of posterior 
body segment nearly circular in cutline, brown, with numerous minute 
black specks, slightly rimmed at posterior margin, and in young examples 
obscurely bituberculate; furnished with several strong marginal hairs, 
and with four minute, striate, centrally placed, spatulate appendages. 
Spiracles round, the two anterior pairs sometimes with brown rims, 
the rest pale. Posterior segment with a single fleshy proleg.
