broods, one apipearing in the Spring and disappearing in July or August 

 and anotiier in the Fall, which disappears with the approach of cold 

 weather. So f<ir as I know, there is no record of the hibernation of the 

 last brood. 



C. virgiiiieiisis AwA C. Uberta--\ have observed on the foliige of 

 white and pitch |)ine as late as Oct. loth, and specimens have lived under 

 my care feeding on tlie needles of the latter, for which they show a pre- 

 ference, till toward the close of No\-L-mber. 



C. canipesiris Sav. — Several years ago Mr. John ALhurst of diis city 

 found some forty or hfi)' 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 (Knt. .Am., vol. II, p. 71,). 



Oniitting canipesiris and fiilleri which form one group, if not a 

 single species, the remaining species of the genus may be placed in a 

 second grouj), which (rom their known habits, and close relationship, 

 we have good grounds to ijelieve do not differ materially from each other 

 biologically, but like liberta anil virginiensis pass the larval condition in 

 the wood of pines and the adult stage on the foliage of the same trees. 

 Compared with Chiysobof /iris 'And Anlhaxia the species of this genus are 

 very sluggish, and do not take readily to flight, Init, hke many other 

 Coleoptera, when disturbed, fold their legs and antenuce 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 an\' othcM', but hav^ taken it also on apple, maple, and oak. It 

 appears to fiequent particularly trees with light colored trunks,, whicli 

 harmonize well with the color of the insect and may serve to protect it 

 against detection by its natural enemies. 



D. piigionata Germ. — Twc) examples taken on trunks of maples. 

 June 5th and Sept. 27th. 



D. aspcrata Lap. t^i (n>ry. — Several specimens taken on dead hick- 

 ory suggest that the species may breed in this wood as well as in oak. 

 May 20th. 



D. punciitlata Sch. — A living specimen taken in the interior of a 

 large branch of Finns rigida Sept. 15th. Also occurs quite commonly 

 on the leaves and trunks of Pinits sirohtis. Captures on May loth, 

 June 15th, and Sept. 5th-20th. 



Anlhaxia 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
