is by far the most remai'kable species of this section of the genus. 

 There are but two specimens known, and the male above described 

 I owe to the kindness of Mr. C. H. Roberts, of New York. 



A. flavipeilliis n. sp. — Somewhat robiTst, but moderately depressed ; 

 head black ; pronotu;u dark riifo-piceous ; elytra pale flavate ; abdomt^n pice- 

 ous throughout ; legs pale flavate ; antennfe piceous-black, the basal joint very 

 dark rufo-testaceous ; integuments polished, very finely and extremely sparsely 

 pubescent. Head as wide as the prothorax ; eyes rather small, somewhat con- 

 vex, the tempora about three-fourths longer, less strongly arcuate but rather 

 more prominent ; transverse basal impression distinct ; surface feebly convex, 

 finely but distinctly and rather densely punctate, a wide median area impunc- 

 tate ; antennal prominences strong but small and very short ; antennpe rather 

 slender, very feebly incrassate, as long as the head and prothorax, basal joint 

 about equal in length to the next three together, second scarcely visibly longer 

 than the third, tenth very slightly longer than wide. Prothorax fully three- 

 fourths wider than long ; sides near the apex broadly subangulate, the angle 

 narrowly rounded, thence feebly convergent and nearly straight to the apex, 

 slightly more strongly so and very feebly arcuate to the basal angles which 

 are rounded ; base subtruncate towai'd the middle ; ajjex broadly and distinctly 

 arcuate, very feebly sinuate near each angle, the latter very slightly obtuse, 

 very narrowly rounded, not prominent ; disk strongly impressed in the middle 

 at each side of the impunctate median line, tlie impression reflexed posteriorly 

 and extending thence anteriorly nearer the sides, becoming broader and feebler 

 and not attaining the apex ; intermediate callus smooth, imj^unctate ; impressed 

 areas finely, rather densely punctate. Eli/ti-a slightly wider than long, one- 

 third wider and nearly three-fourths longer than the prothorax ; sides nearly 

 parallel and straight ; surface with a strong elongate impression at each side 

 of the suture at base, rather finely deeply and densely punctate. Abdomen 

 rather distinctly narrower than the elytra ; sides parallel and very distinctly 

 arcuate ; surface very minutely and extremely sparsely punctate ; under surface 

 more densely so and with rather long cinereous and conspicuous pubescence. 



Male. — Sixth ventral segment with a very small narrow elongate-oval area, 

 not attaining the ajjex, which is more densely and finely pubescent ; seventh 

 very broadly, feebly emarginate throughout its apical width, the middle of the 

 emargination transverse ; eighth flattened but not impressed. 



Female. — Seventh segment very broadly arcuate, the median portion with a 

 fringe of very fine porrected membranous hairs ; eighth broadly impressed. 



Length 3.'4 mm. 



California (Mendocino, Santa Clara and Monterey Cos.). 



The specimens before me consist of a single representative from 

 each of the above localities — one male and two females. The 

 species differs from annectens, not only in the characters given in 

 the table, but in its shorter and rather more coarsely punctate elytra, 

 and in the sexual characters of the female.
