HARPALIN/E 187 



moderate and not very convex eyes, minutely, sparsely punctulate 

 and finely rugulose, the foveae strong and sublinear, flexed internally; 

 antennae only moderate in length and rather stout, of the usual 

 color; prothorax shorter than usual, one-half wider than long, the 

 sides more evenly and only moderately rounded, feebly converging 

 and nearly straight basally; surface throughout nearly as in incertus 

 and with a similar narrow concave marginal gutter; elytra shorter, 

 parallel, fully a fifth wider than the prothorax, the apex rapidly 

 obtuse, the oblique sinus feebler, almost obsolete, the humeri not at 

 all denticulate, the striae fine but groove-like as usual, the intervals 

 flat or very nearly, the discal puncture small, at three-fifths, the 

 minutely punctulate apical part of the alternate intervals very short 

 and indistinct, the usual row of large punctures on the seventh 

 interval at apex unusually distinct; basal joint of the hind tarsi but 

 little longer than the next two or the fifth. Length (9) 9.6-11.0 

 mm.; width 3.9-4.3 mm. California (San Francisco Bay). 



sericatus n. sp. 



16 Prothorax shorter, one-half wider than long; elytra broad, posteriorly 

 dilated and widest somewhat behind the middle, densely opaque 

 in both sexes and almost equally. Body stout, moderately convex; 

 head minutely, sparsely punctulate throughout, the rugulosity not 

 obvious, the foveae well developed, deep and slightly linear; eyes 

 strongly convex, the antennae rather stout, black almost throughout; 

 prothorax strongly rounded at the sides anteriorly, the sides strongly 

 converging and straight posteriorly, minutely sinuate just at the 

 angles, which are acutely subprominent; apex deeply sinuate, not 

 very obviously narrower than the base; surface broadly and unusually 

 feebly convex, rapidly declivous for a short distance at the sides to 

 the rather narrow and deeply concave gutter, which does not 

 broaden posteriorly but continues to the basal angles; disk punc- 

 tured throughout, the punctures fine and sparser centrally, very 

 dense and subcoalescent basally, the admixed coarse punctures of 

 the sides, characterizing the preceding section, not visible; foveae 

 large but very shallow; stria fine but distinct, attaining apex but 

 not the base; elytra a little less than one-half longer than wide, 

 almost parallel (9), posteriorly inflated (cf), fully two-fifths wider 

 than the prothorax, broadly obtuse behind, the sinus very distinct 

 though not deep; striae fine but deep and cleft-like, the scutellar 

 very long, the intervals not quite flat, the discal puncture small, 

 at three-fifths; basal joint of the hind tarsi as long as the next two, 

 distinctly longer than the fifth; male with two apical abdominal 

 setae, the female with four as usual. Length (cf 9 ) 11.3-13.0 mm.; 

 width 4.3-5.2 mm. California (northern coast regions). [A. brevi- 

 collis Lee.] consobrinus Lee. 



Prothorax not so short, always less than one-half wider than long; elytra 

 relatively not so broad and always parallel, generally very shining 

 (cf ) to more or less opaque (9 ) I/ 



17 Apical sinus of the elytra nearly obsolete, barely visible; elytral 

 intervals not more convex apically, remaining perfectly flat. Body 

 small in size, moderately convex, the head and pronotum ( 9 ) strongly
