sides, gradually narrowed from the middle to the tip; disc transversely convex, not 
polished, but very imperceptibly granulate, sparsely and strongly punctured. Elytra 
cylindrical, not wider than the prothorax, convexly declivous behind; sparsely 
clothed with very short and fine yellowish pubescence; strive composed of rather 
large shallow punctures, interspaces not narrower than the strive, almost impercepti- 
bly punctulate. Beneath nearly smooth, sides of metasternum with a row of punc- 
tures, sides of ventral segments feebly punctured. Legs piceous, front tibize with 5 
distinct acute teeth on the outer edge, which is also sparsely fringed with long yel- 
lowish hairs, with a fine apical spine at innerangle; tarsi yellow, narrow, third joint 
not dilated. Antenne with the scape long, the first joint of the funicle large, rounded, 
second indistinct, closely connected with the club, which is large, oval, not pointed,

9. THE PINE TIMBER BEETLE. 
Pityophthorus materarius (Fitch). 
This bark-borer has been noticed on p. 173. We found numbers of 
them at Brunswick in August, 1881, which were identified as such by 
Dr. Horn, under the bark of a spruce, which had been cut down the 
preceding November; a few larve occurred with these. 
10. Hylurgops pinifex Fitch. 
This species, noticed on p. 177 as occurring in pine stumps, was also 
found mining under the bark of spruce stumps of trees felled in Novem- 
ber, 1880. The track was made at the beginning of the roots, and is 
slightly sinuous, two or three inches long; 3™™ wide, while the diameter 
of the hole for the exit of the beetle is 24-3™™ in diameter. 
11. Cupes concolor Westwood. 
Order COLEOPTERA; family CUPESID&. 
This beetle has been found by Mr. G. Hunt upon or among spruce 
boards in a tannery in Northern New York; hence he thinks it may be 
J ; 
a spruce insect. 
12. THE PINE NEPHOPTERYX. 
Pinipestis Zimmermanni Grote. 
This is said by Mr. Zimmermann to be destructive to young spruces 
in New York. (Can. Ent., xii, 59. See p. 182.) 
AFFECTING THE LEAVES. 
13. THE CHECKERED PINE MEASURING WORM. 
Feeding on the leaves in August and early September in Maine, a geometrid cater- 
pillar with the body very slender, gradually increasing in width towards the anal 
proplegs. 
Head very small, much narrower than the body, deeply indented on 
the vertex, each side angular above. General color that of the bark of 
the spruce twigs, checkered with black and gray, with a lateral black
