under the bark of the slabs, while a fungus growing on an ehii log yielded 

 Cuacjus clavipes and Tritoma ihoracica. 



Hister lecontei^ and coarctatus, Pkgaderus transversus and sayi^ 

 Teretrius americanus^ and two specimens of Hister carolinus, were all the 

 Histeridce discovered; all were taken under bark or crawling over the logs. 



Of the Elateridce^ one or two Alaus oculattis were found resting on 

 the side of a log as if they had just alighted from a flight; Adelocera brevi- 

 cornis and obtecta were taken» the latter always on the board piles. Several 

 Elater apicatus were taken on the trunk of a partly dead elm in the day- 

 time, while a single specimen of this species was found on an elm log at 

 the same place by use of a dark lantern. This was the only specimen of 

 Coleoptera (excepting two or three Magdalis armicollls which were evi- 

 dently hiding in crevices in elm bark) that was taken by this method of 

 collecting. Several specimens of Elater sanguinipemiis were beaten from 

 Alnus incana which grows abundantly in the pasture near the mill. 



Chalcophora brevicoUis Casey was taken quite commonly on the slab 

 piles, while liberta was rarely seen. Dicerca divaricata was common on 

 the maple cordwood, and caudata, a very distinct species, was beaten in 

 numbers from Alnus i7icana sprouts. D. tuberculata L. & G. and chrysea 

 Mels. (commonly confused with tenebrosa) were taken on the slab piles. 

 Fifteen specimens of the latter were found on the trunks of a few fire-injured 

 fir-trees [Abies balsamea) from June 20 to 25, 19 10. From my obser- 

 vations it seems probable that it breeds in this conifer. It may be noted 

 here that tuberculata was taken at Wales, Me., ovipositing in the bark of 

 a healthy twelve-inch hemlock, two or three feet above the ground. 



Buprestis sulcicollis was taken once on the logs and once flying near 

 a steam saw-mill about half a mile away. (This species was also taken at 

 South Paris, Me,, on slab piles, June 14, 19 10.) In previous years single 

 specimens of B. maculiventris, consularis, and impedita Say (commonly 

 called striata) have been taken on the logs. It may be recorded that this 

 latter species was taken ovipositing-on the stump of a large white pine that 

 had been cut the previous winter. The beetle was hidden by the scarf 

 of the cutting and was laying the eggs in the cut surface of the stump; the 

 date was June 23, 1910. Poecilonota erecta L. & G., formerly called 

 cya?iipes Say, has occurred at Monmouth once or twice. Large numbers of 

 Melanop/iila fulvoguttata, and a few acuminata were taken, the former 

 always on hemlock logs. It was also very abundant on hemlock bark in 

 a clearing at Wales, Me. A single specimen of Anthaxia viridicornis has 

 been taken.
