216 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
90, THE WHITE-NECKED PINE-BEETLE. 
Dichelonycha albicollis Burmeister. 
Order COLEOPTERA; family MELOLONTHID®. 
A small beetle half an inch long or somewhat less and resembling the Rose bug, No. 
50, in its shape but with wing-covers of a shining brilliant green, becomes quite com- 
mon 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 the genus to which 
it belongs by its thorax having a more distinct but a very shallow groove along its 
middle. (Fitch.) 
The beetle.—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 confluent punctures and show three 
smooth raised lines on each, running lengthwise. 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. (Fitch.) 
91. THE PINE ANOMALA. ' 
Anomala pinicola Melsheimer. 
Order COLEOPTERA; family MELOLONTHID &. 
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 antenne 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 proba- 
bly be found also in our own State. (Fitch.)

tree-hopper 0.14 long, of a black color, its head pale yellow with a black band on its 
anterior margin, its thorax prettily sculptured with fine transverse lines and with a 
pale yellow band anteriorly, its wing-covers with a broad hyaline white margin on 
the outer side, interrupted with black back of the middle and having a shining black 
dot near the tip, its under side and legs pale yellow. (Fitch.)

Clastoptera testacea Fitch. 
A similar insect to the preceding, but of a pale yellow color, 0.20 long, its scutel 
darker tawny red or yellow, its wing-covers with a shining black dot near the tip, and 
often with a black dot upon each side of the breast. Appearing upon pines and also
