TRIBE VI. PHLCEOTRIBINI. 661 



apical margin rounded, very finely granulately punctured, with a faint, 

 smooth dorsal line. Elytra cylindrical, moderately slender, strongly punc- 

 tate-striate, third interval moderately elevated toward tip, the first also 

 elevated, the second slightly narrowed on declivity. Male with two small 

 approximate tubercles on front, which is uniformly convex in female. Length 

 1.5 mm. 



Occurs in pine from New Jersey and District of Columbia to 

 Tennessee and Florida. The European species of the genus live 

 polygamously on pine, the parent galleries being star-shaped. 

 Packard found bifurcus at Montgomery, Ala., under bark of 

 southern pine, making a long, sinuous., narrow primary gallery, 

 from which rather short secondary galleries run out at nearly 

 right angles.

Differs only in being larger, the greater elevation of the crests formed 

 by the elevations of the first and third intervals and the consequently more 

 evidently narrowed second interval. Length 1.8 mm. 



Anglesea, New Jersey. Georgia, under pine bark. 



V. POLYGRAPHUS* Erichson, 1836. (Gr., "much" -j- "writing.") 

 Small cylindrical species, narrowed in front, rounded behind ; 

 head of male with one, and sometimes two acute tubercles in 

 front; female without acute tubercles in front; base of elytra 

 straight, asperate. They occur in the eastern and northern 

 states, in Canada and West Virginia, at times in incredible num- 

 bers, and constitute an important part of the insects destructive 

 to spruce. (Hopkins, 1901-b.) 



1070 (9157). POLYGRAPHUS RUFIPENNIS Kirby, 1837, 193. 



Black, elytra dull red, legs, mouth and antennae rufous; minutely punc- 

 tured, hairs white, decumbent, like minute scales. Antennae with long, 

 strongly clavate scape, and 5-jointed funicle, first joint stout, as long as the 

 others united, 2 5 gradually increasing in thickness, short, closely united, 

 forming a conical mass; club strongly compressed, pubescent, without 

 sutures, oval-pointed, with lower side less curved than upper and broader 

 at base. Eyes divided, the two parts connected by a smooth corneous line, 

 along which a few separate lenses may be scattered. Thorax simply, very 

 thickly and minutely punctate. Elytra rugosely punctulate, scarcely striate, 

 or with several rows of larger punctures; clothed with small stout scales 

 and with rows of scarcely longer erect bristles, pubescence short, coarse, 

 depressed and of a yellowish-gray color. Ventral segments nearly equal, 

 first and fifth slightly longer. Tibiae moderately dilated with three or four 

 small teeth near tip, which is obliquely truncate, the inner angle slightly 

 mucronate; tarsi slender, third joint not emarginate, fourth small but dis- 

 tinct, fifth as long as the others united. Length 2 2.5 mm. 



*The generic name Lt-pisoinus Kirliy (1837) is also used for these species. We 

 adhere to the name in use until the continuation of Dr. Hopkins' work fixes the generic 

 position of each species.
