 at middle. However we follow Fisk in placing it under that 

 genus until a careful strnlv of all allied forms can be made.

 1906, 31. 



Elongate, slender, subcylindrical. Dark reddish-brown; above sparsely 

 clothed with elongate, yellowish scales, forming obscure irregular mark- 

 ings on the elytra. Beak feebly tricarinate, foveate between the antennae, 

 coarsely punctate; front with a small, deep fovea. Thorax one-fourth longer 

 than wide, widest at middle, sides broadly rounded; disc with a narrow me- 

 dian carina and numerous coarse shining tubercles. Elytra not wider at base 

 than middle of thorax, humeri small, rounded; striae indistinct, marked by 

 coarse punctures, these separated by slightly elevated tubercles; intervals 

 each with an irregular row of tubercles, more strongly developed on the 

 alternate ones, which are also distinctly elevated. Length 6.5 6.8 mm. 



Pisgah Ridge, Transylvania Co., X. C., at an elevation of be- 

 tween 5,000 and (1,000 feet. Highlands and Grandfather Moun- 

 tain, X. C., June. Occurs on the under side of freshly cut spruce 

 chips lying on the ground. 



II. PACIIYLOBIUS Lee., 1870. (Gr., "thick" + "lobe.") 



Beak as long as thorax, rather stout, not curved, feebly im- 

 pressed between the eyes, slightly widened at tip; antennal 

 grooves reaching the front margin of middle of eyes; antennae 

 si oul, scape not quite reaching the eyes, first and second joints 

 of funicle each one-half longer than 3 7, which are short and 

 gradually broader; mandibles flattened, the lower tooth of the 

 other genera the front one here; prosternum broadly emarginate 

 in front and fringed with long yellow hairs; femora clavate, be- 

 neath deeply sinuate and strongly toothed; tibia- short, suddenly 

 widened, strongly sinuate above the middle, expanded at tip so 

 that the corbels are very wide.

Elongate-oblong, robust, Dark brown, very sparsely clothed with short, 

 prostrate white, yellowish or reddish-brown hairs which form small distant 

 patches on the alternate intervals of elytra. Thorax one-fourth wider 

 than long, sides parallel on basal half, feebly convergent in front of middle, 

 slightly constricted behind apex; disc densely marked with short concentric 

 ridges, between which are coarse punctures bearing minute prostrate hairs; 

 a narrow median line smooth. Elytra slightly wider than thorax, base 

 truncate, sides subparallel to apical third, thence converging to the 

 rounded apex; striae shallow, cheir punctures oblong; intervals flat, densely 

 rugose-granulate. Length 9 11 mm.
