231. Marbled pine-borer, Monohammus marmoratus, Randall. 
A largo white grub very similar to the last preceding one, and 
boring in the interior of the wood, often in the same trees and 
logs with it. The beetle coming abroad in July and very simi¬ 
lar 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 
ochre 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 
antennae in the females with an ash-gray band at the base of 
each joint, their length in the two sexes as in the preceding 
species. 
232- White-scutblled pine-borer, Monohammus scutellatus, Say. 
[Plate iii, fig. 7.] 
A large white grub closely like the foregoing and boring in 
the wood in a similar manner, in the month 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, re¬ 
sembling spots of white mould, 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 antennae 
double the length of the body in the males, and in the females
