except the entire abdomen, which is black; elytra sometimes 

 feebly infuscate toward the middle ; pubescence coarse, moderatel}'^ 

 long and abundant. Head subquadrate, truncate bat scarcely at 

 all impressed at base, the angles narrowly rounded ; tempora 

 parallel, rather longer than the eyes which are moderate in size 

 and convexit}"; surface coarsel}' and unevenly punctate, the punc- 

 tures xQvy sparse toward the broad smooth line, but closer and 

 with the interspaces reticulate toward the sides ; antennjfi short, 

 slender, very feebly incrassate, scarcely as long as the head and 

 prothorax, the tenth joint a little wider than long. Prothorax 

 subequal in width to the head, short, scarcely as long as wide, the 

 sides feebly oblique and straight posteriorly ; disk somewhat 

 finely but strongly, rather unevenly punctate, the punctures gen- 

 erally well separated. Elytra barely two-thirds longer than wide, 

 twice as wide as the prothorax, the sides parallel and evenly 

 arcuate ; apex rather obtusely rounded ; humeri moderately ex- 

 posed at base, broadly rounded ; disk somewhat convex and finely 

 but strongly punctate, the punctures close but distinctly' separated. 

 Length 1.15 mm.; width 0.65 mm. 



California (San Diego). This is one of the smallest species of 

 the genus. 



41. A. TagaiiS u. sp. — Somewhat narrow, moderately convex, shining, 

 pale flavo-ferrnginous throughout, the pubescence stiff, moderately long and 

 abundant, subdeeumbent. Head subquadrate, feebly convex, truncate and 

 unimpressed at base, the angles rather broadly rounded; tempora parallel and 

 distinctly longer and nearly as prominent as the eyes, the latter moderate in 

 size and not very convex; punctures very coarse, sparse, scarcel3' closer and 

 with the interspaces highly jjolished toward the sides; antenna; somewhat 

 slender, very gradually and feebly incrassate, distinctly shorter than the head 

 and prothorax, the tenth joint slightly transverse. Prothorax trapezoidal, 

 much narrower than the head, not quite as long as wide, widest and narrowly 

 rounded at apical fourth, the sides thence moderately convergent and straight 

 to the base; disk rather coarsely, deeplj', evenly and densely punctate. Elytra 

 three-fourths longer than wide, fully twice as wide as the prothorax, the sides 

 parallel and In'oadly, feebly arcuate; apex moderately broadly rounded; 

 humeri well exposed and rounded; scutellar impression and omoplates com- 

 pletely obsolete; punctures deep and somewhat dense, not much larger than 

 those of the pronotum. Abdomen finely and rather sparsely pxinctate, scarcely
