plied with tiff, spine-like Hairs of various jonathes The ‘anal § segm 
has a single fleshy proleg. When seen from above this segment rapid ry at 
narrows to midway its length, the posterior half forming a rounded, — 
lobe-like projection of about one half the width of the anterior portion 
of the segment. On the projection are four long, stiff, spine-like hairs — 
and a marginal crown of shorter spine-like processes, each of which — 
ends ina fine, eurved, hair-like lash. (Described from two specimens.) 
Pupa. —The pupa is 3.5 to 4 mm. in length. It is pale ene 
in color, naked, and furnished with scattered stiff hairs of considera 
length. The wing-pads, antenne, and legs are folded obliquely over oa 
ventral surface. The abdomen ends in a pair of rather long, tapering, 2 
brown spines, which are very thick at the base. In the older specimen — 
the black eyes and dusky marking of the wing-covers show through the 
thin pupal skin. (Described from two specimens. ) 
Imago. (Plate IIL, Fig. 8.)—Length 3-4+.5 mm. Elongate oval 
in shape, with a shining surface. Color very variable, ranging from . 
almost black to entirely ‘pale brownish, the pale variety ‘being the com- — 
mon form in Illinois. The head is dull rufous, with a few punctures; — 
antenna black. The thorax is pale, with a few faint punctures on the — 
surface, a distinct posterior transverse impression, not limited at the — 
ends. Ee. 
The legs are dull reddish or testaceous, the hind legs fitted for leap- 
ing. The wing-covers are finely densely punctured, not striate, and 
each has a whitish longitudinal stripe on the middle, extending nearly — 
fo the apex. These stripes are visible on even the palest specimens. — 
The variety blanda has the under side of the body and the sides of the | 
thorax narrowly piceous. <it 
The preceding descriptions of larva and pupa were drawn up by an 
assistant, Mr. John Marten, from the office specimens, not accessible

(Ips fasciatus, Oliv.) . : 
(Plate IV., Fig. 3-5.) - 
_ Among the insects attacking the kernel in the earth, is the hitherto 
undescribed larva* of a beetle, [ps fasciatus, which in ‘the adult state 
is abundant everywhere, feeding upon a great variety of vegetable sub- 
stances, fresh or in a state of “decay. The adult beetle has long oe 2 
known as oceasionally and slightly injurious to corn in the ear; but the 
fact that the larva may infest seed corn after planting, although first 
noted by us in 1883, has not hitherto been published. “a 
My first observation to this effect was made at Normal, IIl., Tune eG 
18 of the above year. In a field of corn a part of which had been in a 
pasture for fifteen years preceding, while the remainder had grown _ 
turnips the year before—which, however, had not been removed from 
the ground—large numbers of these larve were found in and about — 
the seed kernels. + From the first, stalks were growing fully two inches E 
high. Occasionally a larva was seen in the space between the rows, ba

* Although the larva of this beetle was rudely figured many years ago (Pack- 
ard’s Guide to the Study of Insects, p. 444), the immature stages of the species have 
not anywhere been described. 
+ The field had been twice planted because of a partial failure of the first seed, 
and the Kernels of both plantings were infested.
