INSECTS INJURIOUS TO THE MAPLE. 109 
pubescence erect and abundant. He has received specimens from Mr. 
J. A. Lintner, said by him to depredate on maple trees. “It is easily 
known,” adds Leconte, “ by being more hairy than the other species, 
with the interspaces of the elytra sparsely punctured, so that the rows 
of punctures appear confused.” 
8. Stenoscelis brevis Boheman. 
Order COLEOPTERA ; family CALANDRID#. 
This beetle occurred in a partly rotten stump of the red maple in a 
swamp at Providence, June 1, in company with Dicerca divaricata and 
Xestobium affine. All these beetles were submitted to Dr. Leconte for 
identification. The mine is irregular, sinuous, 1.5-2™™ in diameter, and 
were quite numerous. 
9. Nestobium affine. 
Order COLEOPTERA; family PTINID A. 
Several specimens of this beetle occurred June 1 in a rotten stump, 
with the larve, which closely resembles those of Ernobius. It makes a 
sinuous mine 4"™ in diameter, and opening externally by a round hole 
3™™ in diameter; the burrows being filled with fine excrement. 
Larva.—Body cylindrical, white, soft, very full and rounded at the end, a little the 
thickest at the thoracic portion; 3 pairs of thoracic, 3-jointed rather siender feet. 
Head rather large, more than half as thick as the body. End of abdomen covered 
with rather dense yellowish hairs. Length, 10™™; thickness of body, 3.1-4™™, Fig. . 
441 of Hrnobius mollis in my Guide to the Study of Insects well represents the general 
appearance of this larva. 
AFFECTING THE LEAVES. 
10. THE GREEN-STRIPED MAPLE WORM. 
Anisota rubicunda (Fabricius). 
Order LEPIDOPTERA; family BOMBYCID#. 
Sometimes nearly stripping soft maples of their leaves, large smooth worms longi- 
tudinally striped with pale and darker green lines, and recognizable by two anteriorly- 
projecting black horns on the second segment behind the head, and transforming to a 
pale, ochre-yellowish, thick-bodied moth, tinged, especially on the fore wings, with a 
rosy hue, and expanding a little over two inches. 
Althongh in the Eastern States this insect, especially the moth, is 
not common, yet we have observed it as far east as Brunswick, Me., 
where it feeds on the maple, the moth there appearing the middle of 
June; in the Western States, Illinois, Missouri, and Kansas, it proves 
during certain years very destructive, entirely or nearly stripping the 
soft or swamp and sometimes the silver maple of its leaves, and dis- 
couraging people from planting this tree along roadsides. It is known 
to feed on the oak.
