696 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



22. The whitescuteled pine-borer. 

 Monohammua 8outellatu8 Say. 



A large white grub, closely like the foregoing, and boring in the wood in a sinailar 

 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 resembling spots of 

 white mold, their surface rough from coarse con- 

 fluent punctures and the thorax similarly punct- 

 ured 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 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 abun- 

 dant beetle in Maine and northern New 

 England generally, and especially in the 

 lumber 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 and Oregon 

 along the Pacific coast. Though I have 

 taken it on the white pine, in Maine, in 

 July, I can not relate more concerning its 

 _, „„ „ , habits and larval forms than is contained

23. The pine-eating gay-beakd. 



Eupogonitis pinivor a Fitch. 



Order Coleoptera ; family Cerambycidje. 



A small grub resembling a young apple-tree borer, mining the wood of the pine, ana 

 in July becoming a small cylindrical long-horned beetle, which is found upon the 

 leaves, 0.25 long and about a third as broad, clothed with numerous erect black hairs 

 on the body and antennae, and gray ones on the legs ; its color shining pale chestnut, 

 with irregular and oblique and transverse spots and streaks ofgray on the wing-covers, 

 which are coarsely punctured, the punctures dense on the base and tine on the apex ; 

 its thorax narrower, slightly darker colored, closely punctured, having a very small 

 tooth-like point on each side and along its middle a gray line which is widely inter- 

 rupted in the center, the sides and also the head with thin gray pubescence ; its 

 antenna? shorter than the body, coarse, and the joints becoming suddenly shorter after 

 the fourth ; its under side blackish brown, the legs pale chestnut. 



This species is of the same color with E. tomentosus of Haldeman, 

 which, however, is larger, with gray hairs instead of black, and the 

 wing-covers with ocher-yellow spots and streaks. (Fiich.)
