fifth ventral is tlattcned and rectilinearly and broadly truncate at 

 apex, the genital segment being broadly bilobed and deei)ly iia- 

 presso-canaliculate along the middle. 



2. A. deimdatus u. sp. — Oblong-elongate and imndlel, feebly convex, 

 rather dull and alutaeeous, black, the elytral apex slightly rufescent from dia- 

 phaneity ; apex of the abdomen except the base of the hfth segment bright tes- 

 taceous; posterior legs black throughout except the l)ase of the femur and the 

 trochanters which are red, the tarsus rufo-piceous; middle legs corresponding 

 in color except that the basal third of the femur is red; anterior legs pale rufo- 

 testaceous throughout; antenna; pale testaceous; pubescence very short, fine, 

 decumbent and sparse, rather dark in color on the elytra and inconspicuous. 

 Head three-fourths as wide as the prothorax, dull but smooth, very obsoletely 

 and sparsely punctulate, the impressions large and strong; epistoma very 

 wide, with a polished and rather pale border, the labrum very transverse; 

 eyes somewhat large and prominent; antenna; somewhat stout, one-half longer 

 than the prothorax, the last three joints larger, the tenth about as long as wide, 

 not much narrowed at base, fifth distinctly dilated. Prolhora.r three-fifths 

 wider than its median length, the sides parallel, feebly and almost evenly 

 arcuate, straight toward the basal angles, which are obtuse but not rounded 

 and not in the least prominent; apical angles right and slightly blunt, apex 

 almost rectilinearly truncate throughout the width, the base vrith a very 

 abrupt and broad arcuate median lobe; disk finely and feebly granulato- 

 reticulate, smooth and alutaeeous, slightly rougher between the submarginal 

 line and the side margin, the latter feebly reflexed as usual ; punctures toward 

 the middle extremely minute and sparse but abrupt and distinct under sufii- 

 cient power. Eli/Ira three-fifths longer than wide, one-fifth wider than the 

 prothorax, parallel and feebly, evenly arcuate at the sides, the apex liroadly 

 rounded and subtruncate, the lateral edges reflexed and the apices subexplan- 

 ate; sutural angles right, not rounded; disk confusedly though feebly and 

 subtrausversely rugose, the punctuation fine and very indistinct. Under sur- 

 face finely but distinctly cinereo-pubescent, the legs well developed. Length 

 3.3-4.0 mm. ; width 1.25-1.5 mm. 



California (north of San Francisco). 



The three examples before me are males, the apex of the fifth 

 ventral being transverse and abruptly and deeply sinuate at the 

 middle, the genital segment being deeply bilobed. In the female 

 the legs are doubtless paler. This species difters from sculptilis 

 in having the sides of the prothorax very feebh' and almost evenly 

 arcuate and not sinuate toward the basal angles, which are obtuse; 

 the apical angles are occasionally feebly prominent anteriorlv. 



3. A. disjlinctlis n. sp. — Oblong, subparallel, feebly convex, dull, the 

 elytra shining, the integuments strongly granulato-reticulate, much more ol)- 

 soletely on the elytra; body black tliroughout, the apices of the elytra pale;
