Brownsville, Texas (Esperanza Ranch, and San Tomas). Two 

 specimens in the Museum of the Brooklyn Institute. 



Distinguished from any of our species by the black spots near basal . 

 angles of thorax, the divergent thoracic lines and the basal fascia ex- 

 tending along the sides to the middle of elytra. 



Anthribus penicellatus, new species. 



Cylindrical, clothed with white, ochreous and brown hairs. Thorax and elytra 

 with tufts of erect hairs, the middle one of thorax black and long. Head and beak 

 clothed with yellowish-white and ochreous hairs. Thorax as long as wide at base, 

 narrower at apex, nearly parallel behind, base slightly arcuate, side margin extend- 

 ing to the middle, disk finely and sparsely punctured, covered with brown and 

 ochreous hairs, three brush-like tufts at middle transversely placed, the middle one 

 black and the largest, near the outer tufts denser white hairs forming arcuate indis- 

 tinct lines, converging towards apex. Elytra parallel, declivous behind, with rows 

 of coarse punctures, surface with white, ochreous and brown hairs, each side with 

 three larger tufts m a row and some smaller ones at sides and apex, the median tuft 

 yellowish white, the others brown, on each side of apex a small round black spot. 

 Length, 3 mm. 



Brownsville, Texas (Esperanza Ranch). One specimen in the 

 Museum of the Brooklyn Institute. 



Distinct from the other species by the absence of a large white 

 spot or a fascia at base, the more declivous elytra at apex and the large 

 prominent median tuft on thorax. The five species of AntJiribus in 

 our fauna may be separated by the following table : 



Pubescence of thorax and elytra uniform, dense, yellowish gray, without erect tufts 



of scales livid us, Lee. 



Pubescence grayish white, yellow and brown forming denser brush-like tufts on 

 thorax and elytra. 



Elytra with a well defined large transverse white spot in front of middle not 



extending to the side margins cornutiis, Say. 



Elytra with a more or less distinct basal fascia of dense white or ochreous hairs 

 extending to the side margin. 



Thorax without larger black spot near each hind angle, the middle and 

 posterior tufts of hairs on the elytra more widely separated from each other 

 than the first and second, the line of denser white and yellowish hairs 



convergent in front vagtis, Horn. 



Thorax with one black spot each side near hind angles, the distance between 

 the first and second elytral tuft equal to that of the second and third, the 

 lines of whitish and ochreous hairs at apex of thorax divergent in 



front '..bipunctattis, n. sp. 



Elytra without basal fascia or spot, elytral tufts equidistant, middle thoracic tuft 

 large and black, the arcuate lines convergent in front but very indistinctly 

 defined at apex panicellatus, n. sp.
