broods, one appearing in the Spring and disappearing in July or August 
and another in the Fall, which disappears with the approach of cold 
weather. So far as I know, there is no record of the hibernation of the 
last brood, 
C. virginiensis and C. liberta--1 have observed on the foliage of 
white and pitch pine as late as Oct. roth, and specimens have lived under 
my care feeding on the needles of the latter, for which they show a pre- 
ference, till toward the close of November. 
C. campestris Say.—Several years ago Mr. John Akhurst of this city 
found some forty or fifiy examples of this species at West Hoboken, N. J., 
sunning themselves on a large dead tulip tree. The species is also known 
to attack sycamore trees (Ent. Am., vol. II, p. 71,). 
Omitting campestris and fullert which form one group, if not a 
single species, the remaining species of the genus may be placed in a 
second group, which from their known habits, and close relationship, 
we have good grounds to believe do not differ materially from each other 
biologically, but like /er/a and wirginiensis pass the larval condition in 
the wood of pines and the adult stage on the foliage of the same trees. 
Compared with Chrysobothris and Anthaxia the species of this genus are 
very sluggish, and do not take readily to flight, but, like many other 
Coleoptera, when disturbed, fold their legs and antenuz closely to their 
bodies, and drop to the ground, where they may easily be captured. 
Dicerca divaricata Say—Fitch in his third report on the insects 
of New York remarks that the beech tree is undoubtedly the original 
residence of this insect. I have noticed it oftener on this tree than 
on any other, but have taken it also on apple, maple, and vak. It 
appears to frequent particularly trees with light colored trunks, which 
harmonize well with the color of the insect and may serve to protect it 
against detection by its natural enemies. 
D. pugionata Germ. —Two examples taken on trunks -of maples. 
June 5th and Sept. 27th. 
D. asperata Lap. & Gory,—Several specimens taken on dead hick- 
ory suggest that the species may breed in this wood as well as in oak. 
May 2oth. 
D. punctulata Sch.—A living specimen taken in the interior of a 
large branch of Pinus rigida Sept. 15th. Also occurs quite commonly 
on the leaves and trunks of Pus strobus. Captures on May toth, 
June 15th, and Sept. 5th—2oth. 
Anthaxia viridifrons Lap.—Bred from a pupa taken from a dead 
branch of shag bark hickory (Carya alba) May 14th. Two days after 
capture it had transformed but remained inactive for nine or ten days
