narrow impuuctnte median line ; eyes rather large, prominent, 

 somewhat before the middle ; antennae slender, incrassate, barely 

 as long as the head and prothorax, the joints strongly obconical, 

 tlie tenth snbqnadrate. Prothorax small and narrow, distinctly 

 narrower than the head and longer than wide, coarselj^, moder- 

 ately closely punctate. El3'tra four-fifths longer than wide, two 

 and one-half times wider than the prothorax, gradually narrowed 

 behind the middle and not ver^- broadly rounded at apex ; disk 

 ver}' coarsely, deeply punctate, the punctures separated by rather 

 more than their own diameters, much finer toward apex. Length 

 3.0-3.3 mm.; width 0.85-1.0 mm. 



California, from Sonoma to the southern parts of the State. 

 The male sexual characters are feeble, the fifth segment being en- 

 tirelj' unmodified on the disk and rounded at apex, the genital 

 segment feebly sinuato-truncate throughout its width. The cor- 

 neous sheath of the copulatory apparatus is quite simple, reduced 

 to a flattened fillet, feebly excavated along its under surface, 

 gradually and evenly- narrowed from base to apex, the latter ob- 

 tusely rounded and blunt, not at all enlarged or modified ; viewed 

 in profile, however, this corneous organ is seen to depart some- 

 what from the usual form in curvature, for, instead of being bent 

 downward, it is feebly bent upward toward apex, the entire organ 

 being protruded vertically downward in normal fashion from the 

 abdominal apex ; it is only about one-fourth as long as the abdo- 

 men. 



4. A. hecate n. sp. — Moderately stout and convex, polished, black 

 throughout, the legs and antennte pale flavo- testaceous; elytra each with a 

 large ill-defined spot near the base and another, rounded, at apical fourth, of 

 testaceous, the suture also sometimes feebly suffused with a reddish tinge; 

 pubescence long, coarse, cinereous, rather sparse but conspicuous. Head as 

 long as wide, convex, strongly, somewhat closely punctate, with a broad 

 smooth median line which almost attains the base; eyes large, prominent, 

 rather before the middle; antenntc not quite as long as the head and prothorax, 

 feebly incrassiite, the second joint short, third elongate and distinctly longer 

 than the fourth, tenth as long as wide. Prothorax small, much narrower than 

 the hend, exclusive of the collar not longer than wide, convex, rather coarsely 

 and closely punctate, broadly rounded at the sides anteriorly, feebly narrowed 

 thence to a short distance before the base where the sides become parallel; 

 collar long and strongly developed, finely, densely punctate, finely constricted 

 at base; basal margin subobsolete toward the middle. Elytra nearly twice as 

 long as wide, about two and one-third times as wide as the prothorax, scarcely 

 visibly wider behind the middle than at base, thence gradually narrowed to
