PINE. LEAVES. 
280- White-Necked Pine-beetle, Dichelonycha albicollis, Burmeister. 
(Coleoptera. Melolonthidse.) 
A small beetle half an inch long or somewhat less and re¬ 
sembling the Rose bug, No. 50, in its shape but with wing 
covers of a shining brilliant green, becomes quite common upon 
pines about the middle of May, eating the leaves, and continues 
about a month. It may be distinguished from the several 
other species of tho genus to which it belongs by its thorax 
having a more distinct but a very shallow groove along its 
middle. 
This species has a black head with its fore part dull pale yellow. Its thorax 
is black and is covered with incumbent ash gray or yellowish hairs, but not 
so close as to hide the ground beneath, whilst the scutel is densely coated 
with white hairs. The bright green wing covers are dull pale yellow along 
their outer margin and also on their inner edge. They are rough from con¬ 
fluent punctures and show (Jirce smooth raised lines on each, running length¬ 
wise. The legs are pale yellow with the hind feet and inner side of the hind 
shanks black or blackish, and the fore shanks have at their outer tips two 
projecting teeth with a small tubercle indicating the place of a third tooth. 
Its length varies from 0.40 to 0 50. 
281. Pine Anomala, Anomala Pinicola, Melsheimer. (Coleoptera. Melo- 
lonthidaa.) 
Feeding on the leaves in June and July, beetles resembling 
the common May beetle, No. 76, but of a much smaller size, 
being only 0.35 long, black, shining, their wing covers slightly 
tinged with chestnut with the suture and outer margin broadly 
black, their antennae pale dull yellowish, and their feet pitchy 
black. I only know this species from specimens from the south, 
but as it occurs in Pennsylvania it will probably be found also 
in our own State. 
2. THE HEMLOCK .—Pinus Canadensis. 
This is much tho most free from insects of any tree in our 
country. Its thick masses of foliage would appear to present a 
favorite lurking place for those insects which delight in a 
deep shade, and the collector is hence often allured to this
