STAPHYLINID^:. 61 



and not at all conspicuously dilated posteriorly. Length 3.2 mm.; 

 width 0.66 mm. California (Redwood Creek, Marin Co.). 



Very distinct in its unusually short antennae, with the penulti- 

 mate joints distinctly shorter than wide and in its comparatively 

 large size, rather narrow abdomen and other characters. 



Echidnoglossa leviventris n. sp. Black, highly shining, the legs 

 blackish-piceous, the vestiture rather long and coarse but not dense or 

 notably pale; punctures fine, well separated, larger and stronger but not 

 dense or coarse on the elytra, sparse but evident on the convex parts of 

 the abdomen; head rather small, as long as wide, a little narrower than 

 semicircular behind the somewhat well developed and moderately convex 

 eyes; antennae blackish, piceous basally, long, very slender, only very 

 slightly incrassate distally, the penultimate joints fully as long as wide, 

 the last as long as the two preceding: prothorax small, narrow, distinctly 

 elongate, much narrower than the head, narrowed anteriorly from about 

 the middle; elytra large, quadrate, more than twice as wide as the pro- 

 thorax and fully one-half longer; abdomen slender, very feebly and 

 gradually dilated posteriorly, at the widest part only about three-fourths 

 as wide as the elytra. Length 3.1 mm.; width 0.63 mm. California 

 (Lake Co.). 



Distinguishable by the small narrow prothorax and the unusually 

 narrow and feebly posteriorly enlarged abdomen, shining black 

 integuments and slender antennae. 



Echidnoglossa tenuicornis n. sp. Moderately slender, deep shining 

 black, the abdomen feebly rufescent except posteriorly, the legs blackish- 

 piceous, with paler tarsi; punctures fine, nowhere very close, strong and 

 moderately coarse but evidently separated on the elytra; pubescence 

 short, close and only slightly pale; head nearly as long as wide, a little 

 narrower than semicircular behind the moderate eyes; antennae piceo- 

 rufous, slightly paler apically and basally, long and very slender, very 

 feebly incrassate distally, the eighth and ninth joints longer, the tenth 

 a little shorter, than wide, the last gradually pointed and as long as the 

 two preceding; prothorax well developed, distinctly elongate, barely 

 at all narrower than the head, narrowed anteriorly in but little more than 

 apical third, with the converging sides rounded and the side angles un- 

 usually broadly rounded and indistinct; elytra" only moderately large, 

 quadrate, three-fourths wider and a third longer than the prothorax; 

 abdomen much dilated posteriorly, where it is rather wider than the 

 elytra, slender at base. Length 2.8 mm.; width 0.6 mm. California 

 (Sonoma Co.). 



To be identified very readily by the slender antennae, long and 

 more anteriorly narrowed prothorax, moderate elytra and strongly 

 claviform abdomen.
