51. A. lielTiiill!; 11. sp. — Eatlier narrow, subparallel and depressed, dull, 

 pale ochreo-flavate throughout above and beneath ; pubescence even, suberect, 

 verj- short, coarse, dense, the hairs strongly and posteriorly arcuate. Head 

 large, quadrate, as long as wide, truncate and unimpressed at base, the angles 

 rather broadly rounded ; eyes moderately small and convex, about three- 

 fourths as long as the tempora, the latter parallel and very feebly arcuate; 

 disk somewhat finely but strongly, very densely punctate, the narrow im- 

 punctate line obliterated toward base ; antennae about as long as the head and 

 prothoi-ax, feebly incrassate, the tenth joint wider than long. Prothorax 

 rather small and very feebly convex, much narrower than the head, not quite 

 as long as wide, narrowly rounded but not angulate near the extreme apex, 

 the sides oblique and very feebly sinuate thence to the base, the basal margin 

 narrow and feebly defined ; punctures somewhat small but deep and extremely 

 dense, the intersi^aces dull and reticulate. Elytra three-fourths longer than wide, 

 fully twice as wide as the iirothorax, obtusely rounded behind; sides parallel 

 and very feebly arcuate; humeri rather widely exj5osed at base, the scutellar 

 impression and om opiates subobsolete; disk depressed, very deeply and densely 

 punctate, the punctures moderately large. Abdomen fineh* and indistinctly 

 punctate, ahitaceous, the legs very slender. Length 2.2 mm. ; width 0.7 mm. 



California (Lake Co.). 



The single female represents a veiy distinct species, which ma}- 

 be known by its depressed and subparallel form, dull lustre, ex- 

 tremel}' dense and not very fine punctuation, and unusuall}- short, 

 peculiarly recurved pubescence. 



52. A. lutiilentus n. sp. — Moderately narrow, somewhat strongly con- 

 vex, shining, pale ochreo-flavate throughout above and beneath; pubescence 

 moderately long, coarse, subdecumbent, even, not very dense. Head sub- 

 quadrate, as long as Avide, arcuato-truncate at base, the angles rather broadly 

 rounded; eyes somewhat large and prominent, about as long as the tempora, 

 the latter subparallel behind them for a short distance; disk finely, somewhat 

 sparsely punctate, with a narrow but apparently entire impunctate line; an- 

 tennse about as long as the head and prothorax, feeblj- incrassate, the tenth 

 joint rather wider than long. Prothorax quite distinctly narrower than the 

 head, almost as long as wide, rather narrowly rounded at apical fourth, the 

 sides thence oblique and nearly straight to the base, the margin just visibly 

 dilated laterally; apex broadly, somewhat strongly arcuate; punctures fine 

 but deep, well separated. Elytra two- thirds longer than wide, fully twice as 

 wide as the prothorax, not broadly, circularly rounded at apex, the sides 

 X)arallel and feebly arcuate; humeri not very 's\-idely exposed, rounded; scu- 

 tellar impression and omoplates obsolete; punctures small but deep and 

 close-set. Legs moderate in length, rather slender. Length 2.0-2.3 mm.; 

 width 0.65-0.75 mm.
