0. brunneum is identical with the cylindricum of Fabr., the Pennsyl- 

 vanicuni of De Geer, the f^ulcatum of Beauvbis, and the unicolor 

 of Drury, which are redescriptions and renamings of Forster's 

 brunneum of 1771. The figure represents an individual of the maxi- 

 mum size, 1.80 inch.; smaller examj)les measure from 0.90 inch, 

 upward. 



Ht/lotrupes bajulus is another of the Geramhycidw. Dr. Fitch records 

 it among the pine insects, and also as sometimes attacking 

 the hemlock {loc. cit.). Dr. Thomas, formerly State Entomologist of 

 Illinois, mentions it as occasionally seriously injurious to hemlock 

 lumber. Dr. Harris represents it as one of the most common of its 

 kind in the vicinity of Boston {Insects Lijurious to Vegetation, page 100, 

 plate 2, fig. 12). Kirby and Spence state of it that the grubs greatly 

 injure the wood-work of houses in London — piercing the rafters of 

 the roofs in every direction, and when arrived at maturity, even 

 penetrating through sheets of lead which covered the place of their 

 exit. It has probably been introduced in this country from Euroi:)e, 

 as it is met with more abundantly near the sea-board. 



Callidium sp? belongs to the same tribe with the preceding, and 

 is of similar habits. The extent of its injuries is not recorded. 



Lepfura Canadensis has been taken from hemlock stumps in the 

 Adirondack mountains. It is probably seldom injurious to living trees. 

 I have found the beetle common on blossoms of the golden-rod (Soli- 

 dago) at Long lake in the Adirondacks, in August. 



The two longicorn borers, of which the species were not identified 

 occurred in the bark of fallen 

 hemlock. The smaller one 

 (Figure 4) resembled the 

 larva of the common longi- 

 corn pine-borer, Monoham- 

 mus confusor (Kirby) — the 

 most perniciovis of the pine- 

 borers. The figures are from

Nyctobates Pennsylvanicus is one of the Tenebrionidce, or "ground 

 beetles." Its puj^ae were found by Mr. Schaupp, on July eighteenth, in
