polished and sparsely punctate beyond the basal dilatation, which is distinct in 

 the male, feeble in the female. Antenn;e inserted near the base, the first joint 

 almost reaching the eye. Thorax not quite as long as wide, sides moderately 

 rounded behind the middle, slightly sinuate before the base, punctuation 

 moderate but largely concealed by the vestiture. Elytra nearly twice as wide 

 as the thorax, not more than one-fifth longer than wide, sides distinctly di- 

 vergent to behind the middle, intervals apparently flat, much wider than the 

 strise. Body beneath and legs densely squamose. Length 2 to 2.2 mm. 



Hab. : California. Described from a single pair (type 5) com- 

 municated by Mr. E. P. Van Duzee, taken at Coachella, Riverside Co., 

 and a single specimen from Palm Springs (collected by Hubbard) 

 erroneously placed with varicorne in my collection. The middle and 

 hind tibial of the male are armed at tip with a moderately long mucro 

 which bears a denticle beneath. This species is to be associated with 

 propinqiiicoriic and modestum, the latter of which it should follow. 

 It is much more densely and coarsely squamose than modestum and 

 is withal a larger and stouter species. Superficially it more nearly 

 resembles propinqueconic, but the latter has a finer and less dense 

 vestiture and a slightly longer undilated beak w^ith more basally 

 inserted antennae. Superficially also it resembles quite strongly the 

 densely squamose form of varicorne which occurs in the same region, 

 but this latter belongs to an entirely different section of the genus. 



A. eccentricum new species. 



Very similar in form, size, and general aspect to griseum. Black, pubes- 

 cence conspicuous but not dense except on the sternal side pieces. Beak (J) 

 as long as the head and thorax, a little thicker at the middle as viewed from 

 the side, slightly dilated at the antennal insertion, polished and sparsely 

 finely punctate apically, more closely so at sides ; 5 longer than the head and 

 thorax, a little more slender and scarcely dilated. Antennae rather distant 

 from the base of the beak, first joint subequal to the next three, the third 

 attaining the eye. Front scarcely to feebly sulcate. Prothorax a little wider 

 than long, sides arcuate medially, moderately constricted in front, sinuate 

 before the basal margin, which is evidently expanded ; punctuation rather 

 close, basal fovea present. Elytra about one-third longer than wide, sides 

 subparallel or feebly divergent basally in the male, more evidently diverging 

 posteriorly in the female. Punctuation beneath moderate. Length 2 to 2.2 mm. 



Hab.: Arizona (Santa Rita Mts., Clemence; Huachuca Mts., 

 Slevin). The type is a male from the first named locality. 



In addition to the sexual rostral differences, the males have the 

 middle tibiae armed with a simple acute apical mucro, the front and
