DESCRIPTION. 
In additional to the general characters of the strawberry root- 
worms given on a preceding page, the following details will serve 
to distinguish this more accurately from the allied species. 
Larva.—The brown hairs of the transverse ventral ridges are few 
and short, all shorter in fact than the corresponding segments. 
The ends of these segments are cut off by oblique grooves, consti- 
tuting triangular tubercles with their apices inwards. Each of them 
bears from five to seven hairs, of which about three are longer than 
the others. The hairs of the median portion of the ridge are di- 
vided into two groups by a narrow median naked strip. The vent 
is surrounded by a circle of about ten short hairs. The two rows 
of lateral tubercles are smooth and shining at the apices, and bear, 
each, two or three rather slender hairs. The dorsal hairs are about. 
six to each segment, and arranged in irregular, transverse rows. 
On the last four segments all the hairs are longer and stouter, and 
those on the back of these segments are likewise more numerous. 
On the last two abdominal rings the dorsal arches are broken into 
four prominent tubercles, sometimes blackened at the apex, and 
bearing especially strong spinous hairs. 
The antenne are three-jointed, very short, little more than twice 
as long as wide, the length of the basal joint being just about its. 
width. The cylindrical process of the penultimate joint, is segmented 
off, forming an accessory article, beside the last one. 
The eyes are represented by a cluster of a varying number of 
minute pigment specks, situated a little distance above the base of 
the antenne ; but they show no external appearance of a cornea, or 
other optical structure. The clypeus is about as long as the labrum ;. 
and upon the middle of the anterior surface of the latter, are four 
long hairs, arranged transversely, and at the inferior edge of the 
posterior surface 1s a row of fourteen strong curved hooks or spines 
projecting backward. The maxillary palpi are strong and thick, the 
two basal jomts being broader than long, the third about as long as. 
wide, and the fourth ovate. The tip of the third joint extends 
scarcely beyond the end of the maxillary lobe. 
The latter is not longer than broad, and is armed with about tem 
stout, blunt spines at its inner margin. The general form of the 
mandibles, seen from above, (Plate IX, Fig. 5, B) is triangular, 
their length being scarcely greater than their width at the base. 
The tip, seen from beneath, is obtuse, and more or less conspicu- 
ously emarginate, often decidedly lobed, in which case the lobes are 
equal. It is never trifid and never acute. Occasionally this bi-lobate 
character of the mandibles is indicated only by a longitudinal groove, 
which scarcely renders the tip emarginate. The anal segment of 
this larva is used as a proleg in locomotion, the grub looping along: 
on a smooth surface after the manner of a Phalenid larva. 
Adult.—(Plate VIII, Fig. 1). From the other genera of the group, 
the genus Paria is distineuished by the fact that the anterior mar- 
gin of the thorax, instead of being carried directly over, curves for- 
ward beneath and behind the eyes in a way to form lobe- like 
processes of the pronotum, called postocular lobes. The body is
