STAPHYLINID.E. 85 



shorter than two to four, which are equal, the tarsal setae few in number but 

 long and very stiff. Length 2.35 mm.; width 0.58 mm. Virginia (Fort 

 Monroe). 



I am uncertain as to the position of this species but leave it under 

 Aloconota for the present; it differs profoundly from the preceding 

 in the unusually well developed infra-lateral cephalic carinse and 

 in having a deep outer sinus at the apex of each elytron. 



The three following species constitute the subgenus Terasota Csy. 



Aloconota (Terasota) perdita n. sp. Moderately stout, only slightly convex, 

 somewhat alutaceous, the abdomen shining, the punctures fine, feebly as- 

 perulate, dense, the pubescence short, not conspicuous; color piceous-black, 

 the abdomen deep black, the elytra barely perceptibly less dark, the legs 

 pale flavate; head well developed, slightly transverse, the tempora longer 

 and fuller than the eyes, rounded and parallel; carinse completely wanting; 

 antennae very long and slender, scarcely visibly and very gradually incrassate, 

 all the joints notably elongate, the last long, gradually pointed, almost as 

 long as the two preceding, the second and third relatively only moderately 

 elongate, equal; prothorax rather small, moderately transverse, evidently 

 wider than the head but much narrower than the elytra, widest at apical 

 third, where the sides are somewhat prominently rounded, the base and apex 

 equal in width; ante-scutellar impression large, transversely oval; elytra 

 nearly as long as wide, subparallel, much longer than the prothorax, the 

 outer sinus at the apices subobsolete; abdomen narrower than the elytra, 

 parallel basally but evidently narrowing apically, the fifth tergite slightly 

 longer than the fourth; metasternal projection moderate in length, angulate; 

 basal joint of the hind tarsi longer than any one of two to four. Length 

 2.9 mm.; width 0.65 mm. California (Gualala, Mendocino Co.). 



The three species preceding are very heterogeneous, and in a 

 more detailed classification of the Athetids would be assigned to 

 different genera or subgenera, of which Terasota is one. The present 

 species differs from both of the preceding in its very long and slender 

 antennae, w T ith all the joints elongate, which is one of the distinctive 

 characters of the subgenus. The male of perdita has a strong and 

 slender discal tubercle on the fifth tergite, at about the central 

 point of the disk and inclining backward, the sixth tergite with 

 two approximate obtuse swollen median teeth, more approximate 

 than either from a slender lateral process. 



Aloconota (Terasota) brunneipes Csy. Slender, moderately convex, dark 

 piceous, the abdomen blackish, slightly paler apically, the elytra not distinctly 

 paler, the legs pale flavate; head rather small, slightly wider than long, the 

 eyes rather large, prominent, the tempora of equal length and lateral prom- 

 inence, parallel, then broadly rounding to the base, the carinse wholly wanting;
