Colyphus furcatus, new species. 



Elongate, black, thorax roseate with a furcate black basal mark, elytra brown to 

 piceous, very near to the suture and parallel with it a longitudinal yellowish-white vilta 

 on each side. Antennae black, joints 4-10, very feebly increasing in width, eleventh 

 longer. Head black, very finely and sparsely punctured, clypeal region yellow, 

 front with a semicircular impression. Thorax wider than long, constricted at apex 

 and very strongly so near base, sides broadly arcuate, surface somewhat coarsely but 

 very shallowly punctate, color roseate when alive or in well-preserved specimens, yel- 

 lowish in old specimens, a furcate black mark at base. Elytra broader at base thatn 

 the thorax, sides nearly parallel, not expanded, apex conjointly rounded, densely and 

 moderately coarsely punctate, color brown to piceous, a yellowish-white vitta starting 

 a little below the base to nearly to apex, closer to suture than to the side margin. 

 Underside and legs black, except femora at base and thorax beneath reddish. Length, 

 6-6.5 ni'ii-

Types. — Four specimens in collection of the Museum of the Brook- 

 lyn Institute of Arts and Sciences. 



This species resembles the Mexican qnadrilhieatus but according 

 to the description differs by' the elytra more parallel, the underside 

 entirely black and the furcate mark at base of thorax. I have taken 

 quite a number of this species but all the specimens are remarkably 

 constant in the furcate spot at base of thorax, which in none of the 

 specimens shows any variation ; even in a small, poorly developed 

 specimen from New Braunfels, Texas, this mark is plainly seen, 

 although faintly. 



Clerus palmii, new species. 



Moderately robust, form of abrnptus, black, shining ; at middle of elytra, a yellow 

 transverse fascia nearly reaching the suture and a little irregular in outline, apex pubes- 

 cent with white hairs. The punctuation of head, thorax and elytra, except towards 

 apex where it becomes finer the same, the fasciae are more sparsely punctured than the 

 rest of surface. The pubesence consists of very short sparsely placed, scarcely visible 

 white hairs, intermixed with longer and darker hairs, long and white at sides of thorax, 

 base of elytra and legs. Length, 



Senator, Arizona. 



One specimen kindly given to me some years ago by Mr. Chas. 

 Palm, whose name I have given to this species as a slight recognition 

 of favors received. 



Closely resembles the black forms of abruptus, but lacks the two 

 basal spots of that species, the thorax in abruptus is much more finely 

 and sparsely punctured than the elytra, while the punctuation of thorax 

 in palmii is as coarse as that of elytra, the yellow fascia on the elytra
