INSECTS INJURIOUS TO THE COMMON JUNIPER. PAD E 
©. A. Walker. The grubs, or larvie, were fully grown, and more numer- 
ous than the pup or adult beetles. How destructive it is, or what the 
habits of the grubs are, must be ascertained by further observation. It 
is evident from the facts already known that there is probably but one 
brood of beetles a year; that they fly about, and lay their eggs in the 
bark of the tree late in June, and probably during July; and that the 
young larve bore in under the bark, and become fully grown in the 
autumn, spending the winter under the bark probably both in the larva 
and pupa states, the beetles appearing during midsummer. 
The larva is rather long and slender, covered with fine hairs, and the 
end of the abdomen is rather blunt. The abdominal segments are very 
convex, and deeply separated by a wide suture. The thorax is about a 
third wider than the rest of the body. The three thoracic segments 
together are as long as they are wide. The prothoracic, or segment 
next the head, is somewhat lunate, and rather longer than the two sur- 
rounding segments; on the upper side is a slightly marked somewhat 
horny square plate, but there is no thickening of the skin on the back 
of the succeeding segments, as usual in the larve of the family (Ceram- 
bycidee) to which this borer belongs. It agrees in all respects with the 
larva of Leiopus xanthoxyli Shimer, except that the head is considerably 
smaller, including the under side and the mouth parts, while the body 
is not so thick. In all other respects the description of the prickly ash 
borer (L. wanthoxryli) will agree with the present larva, for the larvie of 
the two species, which differ very considerably in the beetle state, would 
be easily confounded. The same remedies may be used against this 
insect as against the well known striped apple-tree borer (Sanerda can- 
dida). 
The beetle itself is a slender, smooth-backed species with no ribs on 
the wing-covers. It is pale ash-gray, with a slight purplish tinge. The 
head and prothorax are blackish except on the hinder edge of the pro- 
thorax. The antenne are yellowish brown, with the basal joint and 
articulations between the other joints dark brown. The wing-covers are 
pale ash, with a purplish tinge, and an irregular rounded spot just be- 
hind the scutellum, united when the wings are folded with a similar 
spot on the other wing-cover. The shoulder of each wing-cover is 
tipped with black, which extends backwards from a longitudinal large 
black spot, extending backwards and connecting with a broad black 
band which crosses the terminal third of the wing, leaving the tip 
pale gray. The front edge of this band forms an acute angle in the 
middle of the wing; this band is sometimes partially wanting, and is 
then broken up posteriorly into a few black spots. In front of this 
broad band is an oblique row of short (longitudinal) lines, the first and 
innermost being shortest ; the second one nearly three times as long and 
parallel to the Gostal spot. It is a little less than a quarter of an inch 
(.20) in length.
