and it occurs in the apple in the burrows of codling moths. It is also 
an occasional pest in the pantry, infesting bread and other cooked foods. 
The feeding habits of the larva are much less known, the single 
doubtful statement of Peck as to its occurrence in squash vines being 
the only published record I have seen. Our own notes show, besides its 
occurrence in corn, that the larve breed in rotten apples, specimens 
having been reared by us from crab apples in 1885. 
The annual number of its generations has not been determined, but — 
our breeding notes tend strongly to establish the occurrence of more 
than one brood in a year. Adults have been collected by us as early as 
March 10 to 14 (1885), at which time they were hibernating under 
leaves, and as late as November 15 (1884), when they were taken from 
piled-up driftwood and leaves near a slough. In both cases the beetles 
were evidently in winter quarters. Our numerous collection records 
show that the species is common in the adult stage in Central Illinois 
through April and May and until about the middle of June. May 16 
is our earliest date for the observation of the larva, other examples 
occurring from June 16 to 20. By the middle of July ‘the beetles again 
become abundant, continuing common throughout the remainder of. the 
year, our dates of capture at this season ranging from July 10 to No- 
vember 15. Larve of what is probably a different generation from those 
mentioned above were collected by us in crab apples and transferred to a 
breeding cage. October 6 larve, pups, and imagos were taken from this 
cage, and by the 16th others had completed their transformations, and 
still others by the 21st. 
Tt appears from these observations that the species hibernates as an 
adult, and that it gives origin during the year to at least two genera- 
tions,* breeding in corn, apples, and doubtless other vegetable sub- 
stances. 
The larva enters the earth to transform, making a friable earthen 
cell. 
Description. Larva. (Plate IV., Fig. 3.)—Length 5 to 6 mm., 
width slightly less than 2 mm. Elongate, oblong, depressed, sides nearly 
parallel; general color brownish testaceous, surface minutely granulate, 
the more exposed portions above and below finely punctate; covered with 
dense short grayish pubescence except the head and the greater part 
of the first and last segments, which are smooth. Twelve distinct seg- 
ments besides the head. 
Head four fifths as wide as the first thoracic segment, and four 
fifths as long as broad, dark red-brown. Front with two sulci arising 
at the bases of the mandibles, converging slightly posteriorly, and united 
behind by a transverse suleus. Four shallow impressions are grouped 
about the center of the space included by the sulci. The clyneus is 
indistinctly separated from the front, deeply impressed at middle: the 
labrum transverse, concave, elevated at sides. emarginate in front, it. — 
and the elvpeus with a setigerous puncture on each side. The mandi- 
bles are rather long and not strongly curved, broadly emarginate near 
middle of exterior margin. The maxillary palpi have three nearly equal 
joints, about as long as thick, except the last, which is a little longer
