77 
Brachyleptura canadensis Fabr. One specimen, August 8, 
The larva develops in the wood of several conifers. 
Phymatodes testaceus Linn. One specimen, July 13. The 
larvae occur in oak and are commonly bred from cord-wood. 
Xylotrechus colonus Fabr. Seven specimens, July 13 to 
September 26. This is a common species, usually bred from 
oak but found less abundantly in logs of other deciduous trees. 
Xylotrechus undulatus fuscus Kirby. One specimen, August 
18. This occurs in the wood of conifers. 
Neoclytus acuminatus Fabr. Eight specimens, July 17 to 
September 26. This is an abundant species which develops in a 
great variety of deciduous trees. 
Anthoboscus ruricola Oliv. Five specimens, July 13-18. 
This is known to feed in hickory and elm; these specimens may 
have come from the latter. 
Monochamus scutellatus Say. One specimen, July 19. This 
is an. abundant species in New England feeding in white pine 
logs which are soon ruined if allowed to remain unsawed during 
the warmer part of the year. 
Microgoes oculatus Lee. One specimen, July 19. The larva 
bores in oak and hickory. 
Lepturges querci Fitch. One specimen, July 20. This small 
form develops in the wood of oak, hickory and other trees. 
Hyperplatys maculata Hald. Three specimens, July 14 to 
20. The larvae develop in oak and the wood of other deciduous 
trees. 
Urugr aphis fasciata. Two specimens, July 19. The larvae 
of this species feed commonly in the bark of oak, but occur also 
in that of other deciduous trees and even in pine. 
Family Platystomatidce 
Euparius marmoreus Oliv. Two specimens, August 23 and 
September 26. This is a fungus-beetle. 
Choragus zimmermanni Lee. One specimen, July 28. This 
is a wood-boring species that has been bred from sweet-gum, 
but which must have other hosts.
