and dense toward apex. Prothorax very slightly wider than long, the base 

 and apex equal, truncate, the sides evenly and rather strongly arcuate ; disk 

 with four small denuded callous spots, which are granulato-rugose but not 

 elevated and arranged in a transverse arc at about the middle of the length, 

 the fifth slightly more elongate-oval on the median line at basal third ; on 

 each side of the latter there is also visible a minute callus, which is probably 

 not constant, the median callus slightly impressed and polished. Elytra about 

 one-fifth wider than the prothorax, parallel, the sides straight, the apex 

 abruptly, broadly rounded, subtruncate in the middle ; disk with fine, rather 

 dense punctures, almost completely concealed by the vestiture, the denuded 

 spots small, numerous, arranged without order, smooth, polished and flat. 

 Length 16.5 mm. ; width 4.3 mm.

The vestiture is longer, coarser and denser than in Brothylus, 

 and almost completely conceals the sculpture. The species is repre- 

 sented by a single female.

 Hypermallus Lac. ; Aneflus Lee. 



The following species belongs near irroratum and mucronatum, 

 but has the outer joints of the antennae strongly and finely carinate 

 along the middle of the flat sides, being thus a highly typical mem- 

 ber of the group of species generically separated by Dr. LeConte 

 under the name Aneflus ; it will be noticed that the outer joints 

 of irroratum are also strongly carinate. In fact Aneflus not only 

 cannot be regarded as a genus, but apparently does not form even a 

 distinctly marked group, the tendency to carination being apparent 

 in the majority of species and to a very variable degree, so that it 

 is impossible to assign any limits to the group. 



E. arizonense n. sp. — Form as in irroratum, castaneous throughout, 

 scarcely more shining than mucronatum; pubescence very short and sparse, 

 finely and rather sparsely marmorate on the pronotum and elytra with small 

 irregular patches of denser pale yellowish pubescence, four of the spots of the 

 pronotum forming a transverse row just before the middle. Head coarsely, 

 densely punctate; antennae (male) about two-fifths longer than the body, 

 stout, third and fifth joints equal in length, the fourth distinctly shorter, 

 three to five strongly spinose internally, the remainder with a small inner 

 and outer spine at apex, joints eight to eleven with a fine strong median 

 carina along their compressed sides. Prothorax very nearly as long as wide ; 

 apex and base subequal, truncate ; sides broadly, very obtusely subangulate 

 at or just behind the middle ; disk with a small, elongate, almost impunctate 

 median callus just behind the middle, and a subcallous line at lateral fourth
