156 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
In the absence of another pupa of this genus for comparison, addi- 
tional characteristics cannot now be given. Length, ? of an inch. 
Mr. George Hunt has taken both this species and MW. scutellatus ‘‘com- 
ing out of the white pine” in July in northern New York and in Rhode 
Island. Prof. F. H. Snow records it in the seventh volume of the Trans- 
actions of the Kansas Academy of Science as occurring in the Baptist 
chureh in Lawrence, Kans., ‘where repairs had been made with pine 
lumber.” 
15. MARBLED PINE-BORER. 
Monohammus marmoratus Randall. 
A large white grub very similar to the last preceding one, and boring in the interior 
of the wood, often in the same trees and logs withit. The beetle coming abroad in 
July and very similar to the preceding, but always smaller, measuring 0.75 to 0.90 in 
length, and distinguished from it by having the short hairs coating the base of the 
spine on each side of the thorax of an ocher yellow color instead of white, the thorax 
with numerous confluent punctures across its middle, its wing-covers ash gray marbled 
with tawny brown cloud-like spots, and punctured like the preceding species, but the 
punctures here becoming much more dense towards the base and running into each 
other, the antennie inthe females with an ash-gray band at the base of each joint, 
their length in the two sexes as in the preceding species. (Fitch. ) 
This is not a particularly common insect, though more closely allied 
to the foregoing species than the following better known one. 
16. THE WHITE-SCUTELED PINE-BORER. 
Monohammus scutellatus Say. 
A large white grub closely like the foregoing and boring in the wood in a similar 
manner, in the mouth of June producing a beetle of similar form but of a shining 
black color, its wing-covers having small patches of short hairs here and there, resem- 
bling spots of white mold, their surface rough from coarse confluent punctures and 
the thorax similarly punctured across its middle, its base and apex with irregular 
transverse wrinkles, and its sides with a conical spine which is not clothed with hairs, 
the scutel coated over with white hairs, and the antenne double the length of the 
body. in the males, and in the females with a gray band on the base of each joint, its 
length varying from 0.60 to 0.75. (Fitch. ) 
This is a common and sometimes abundant beetle in Maine and North- 
ern New England generally, and especially in the lamber regions of Lake 
Superior, whence I have received it in large numbers. It also occurs 
in the pine forests of British America and in Washington Territory and 
Oregon along the Pacific coast. Though I have taken it on the white 
pine (Maine) in July, I cannot relate more concerning its habits and 
larval forms than is contained in Dr. Fitch’s brief account given above. 
17. THE PINE-EATING GAY-BEARD. 
EHupogonius pinivora Fitch. 
Order COLEOPTERA; family CERAMBYCID.®. 
A small grub resembling a young apple-tree borer, mining the wood of the pine, and 
in July becoming a small eylindrical long-horned beetle, which is found upon the 
leaves, 0,25 long and about a third as broad, clothed with numerous erect black hairs
