366 MEMOIRS ON THE COLEOPTERA 



wide, the truncate base narrower than the feebly arcuate apex, the sides 

 subparallel and nearly straight from slightly behind the middle for some 

 distance, then rounding rapidly to the apex, slightly converging basally, 

 the angulation very obtuse and blunt; surface with a very close-set 

 mixture of rather fine and of less numerous larger, punctures, with an 

 inconspicuous elongate median spot having stronger sparse punctures; 

 elytra only a fourth or fifth wider than the prothorax, not quite three 

 times as long as wide, very feebly cuneiform, gradually arcuately nar- 

 rowing posteriorly to the narrowly and feebly sinuate apices, the external 

 angle sharply marked but not dentiform; punctures very coarse, small 

 apically, separated basally by about their own diameters; under surface 

 finely, sparsely punctulate, .the prosternum densely; legs rather short. 

 Length (cf ) 10.8 mm.; width 3.0 mm. North Carolina (Southern Pines), 

 Manee. 



This species is very distinct from mcestum, as shown by the above 

 description, but belongs in that vicinity; the elytral punctures 

 basally are even very much coarser than they are in mcestum. 



Hapalosalia densicollis n. sp. -Form and coloration very much as 

 in vibex, black, the elytra each with a pale yellowish vitta from the humerus 

 very nearly to the apex, swollen slightly near the latter and about equal in 

 width throughout to the black sutural vitta; head and prothorax with very 

 short and rather abundant brownish hairs, the elytra with longer erect 

 paler hairs, the entire under surface extremely densely and finely punctu- 

 late and with a dense covering of short decumbent silvery pubescence; 

 head finely, very densely punctate throughout, the sides rapidly con- 

 verging and arcuate behind the large and prominent eyes; antennae very 

 slender, filiform, piceous-black, the third joint a little shorter than the 

 fifth and much longer than the fourth; prothorax slightly elongate, 

 globularly swollen medially, strongly constricted at apex and base, the 

 fine median line feebly impressed, the entire surface finely, very densely 

 punctulate; elytra two and one-half times as long as wide, cuneiform, the 

 apex conjointly rounded, at base two-thirds wider than the prothorax, 

 relatively coarsely, deeply and closely punctate, the punctures gradually 

 smaller to the apex but even there very distinct; legs slender, the pale 

 femora and tibiae all more or less blackish distally; tarsi piceous, the 

 posterior paler. Length (cf ) 7-3 mm.; width 2.2 mm. North Carolina 

 (Black Mountains), Beutenmuller. 



This species differs from every other thus far known in the very 

 dense punctuation of the head and prothorax throughout their 

 extent; otherwise it is somewhat remindful of vibex Newm. 



In a series of sphcericollis Say, sent me by Mr. Beutenmuller, 

 also taken on the Black Mountains, there are four examples with 

 red prothorax, apparently independent of sex, and three with black 

 prothorax. The forms with red, do not differ otherwise from those 

 with black, prothorax, and they are both different from my Canadian
