26 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
denly rounding off; the terminal three segments are indicated by very slightly marked 
sutures, and together form a straight cylindrical portion nearly as long as the three 
segments in advance of it taken collectively. The body is slightly hairy, with a few 
fine, pale hairs on the top of the segment next behind the head. The basal portion 
of the head (epicranium) is broad and smooth, with a few hairs on the edge. The 
eyes are two small black dots, each situated a little behind the base of the antenn, 
and in a line with them. The frontal piece (clypeus) is very small, about three times 
as broad as long, while the minute upper lip (labrum) is two-thirds as long as broad; 
they together form a somewhat triangular portion resting on the inner edge of the 
a cen mandibles, which are broad 
and short, the ends broad 
and square, and blackish 
incolor. The antennz are 
not quite so large or as long 
as the maxillary palpi; 
they are four-jointed; the 
first joint being thick, the 
second joint a third shorter 
than the third, while the 
fourth jointis filiform, and

the head is chitinous, with a mesial subtriangular fleshy area. The chin (mentum) is 
square, not much longer than broad. The under lip (labium) is one-half as long as 
broad. The labial palpi are three-jointed, the basal joint being one-half as long as 
the second; the third joint is minute, short and hairy. The maxillary palpi are four- 
jointed, the first joint being twice as thick as the third, the second and third are of 
nearly equal length, while the fourth is slender and nearly as long as the second 
or third. The maxillary lobe is large and broad, reaching out to the labial palpi 
and as far as the end of third joint of the maxillary palpi; there are a few hairs on 
the end of it. 
On the upper side of the segments behind the prothoracic is a faint, transverse im- 
pressed line, with two or three short creases radiating from each end. On the eighth, 
ninth, and tenth rings these creases become much longer and are parallel to the median 
line of the body, while the transverse crease disappears. 
There are nine pairs of stigmata, one pair on the mesothorax, the remainder on the 
first eight abdominal segments. There are three pairs of rudimentary thoracic feet, 
represented by very minute two-jointed tubercles, the basal joint consisting of a simple 
chitinous ring. The under side of the body is more hairy than above. On the under 
side of the prothoracic segment is a pair of round, smooth, very slightly chitinous 
spots, which are succeeded on each of the other rings by a pair of short, impressed 
oblique lines. 
It is nearly half an inch (.45) in length. 
It may be readily recognized by the four chitinous patches on the prothorax, and 
by the very minute clypeus and labrum. The upper side of the prothorax is inclined 
downward towards the head, but not so much as in Clytus. 
The pupa.—It is white, with the wing-covers reaching to the end of the second 
abdominal segment. The antenne are not much curved, reaching to the end of the 
third abdominal segment, and resting above the legs. The prothorax is swollen just 
behind the middle, and is just as long as broad. The maxillary palpi are long, reach- 
ing nearly to the end of the cox. The labial palpi reach a little beyond the middle 
of the maxillary palpi. The two anterior pairs of legs are folded at right angles to 
the body, the third pair obliquely. The first pair of tarsi reach to the base of the 
second tarsi; the second pair of tarsi reach to the cox of the third pair of legs. It 
is a third of an inch (.33) in length.
