EITTRICIIITES n. g. (Pselaphida). 



Head trifuveate, anterior fovea smaller, front retuse and declivous; 

 antennre ll-jointed. not approximate, though less widely separated than 

 in Bri/axh ; first and second joints stouter, cylindrical, 3 — 10 smaller, 

 nearly equal, the tenth being a little broader, eleventh oval pointed, 

 one-half longer than wide, and as long as the four preceding united ; 

 the outer half is pubescent with long hair. Eyes rounded, convex. 

 Maxillary palpi nearly as in Bryaxis, second joint long, clavate, third 

 nearly rounded, fourth much longer and wider, ovate pointed, with 

 an apical seta. Prothorax with a transverse impression each side near 

 the base, and a small medial fovea; the base behind the impressions 

 is punctured, the rest of the surface is convex, smooth and sparsely 

 pubescent. Elytra convex, wider behind, punctured and pubescent, 

 basal impression faint, sutural stria distinct, discoidal one wanting. 

 Abdomen with dorsal segments convex, finely margined, the first 

 somewhat longer ; third and fourth ventral segments short; the fifth 

 broadly impressed in % . Legs without spines, hind tibiae longer and 

 more curved in % ; tarsi long, with a single claw. 



Differs from Bri/axis by the ninth and tenth joints of the antennae 

 not enlarged, by the antennae less distant at base, the dorsal segments 

 less broadly margined, more convex and less unequal. The front is 

 less protuberant than in the genera with more approximate antennae, 

 and does not overhang the antennal foveae. 



Eu. Ziinitsei'manni. — Rufous, shining, pubescent; head trifoveate, an- 

 terior fovea smaller and less distinct; prothorax campanulate, slightly trans- 

 versely impressed and punctured at the base, with a small medial fovea. Elvtr;» 

 convex, punctured, with no dorsal but a distinct sutural stria. Abdomen with- 

 out impressions on the first dorsal segment. Antennae as long as the head and 

 thorax, tenth joint scarcely wider than the ninth. Length .08 mm. 



From District of Columbia to Texas. A specimen in Dr. Zimmer- 

 manu's collection was labeled Eu. dixnmus, but I have found no 

 description among. his MSS. 



PSEEAPTUS n. g. (Fselaphidse). 



Head broadly excavated in front, obtusely elevated each side above 

 the antennal fovese, which are distant; front convex but not retuse. 

 AntenniB ll-jointed, first and second joints a little stouter and longer, 

 cylindrical, 3 — 8 shorter, ninth and tenth a little broader and slightly 

 longer, eleventh oval pointed, one-half longer than wide, and double 

 the width of the tenth, outer part pubescent with long hairs. Eyes 

 large, convex. JM axillary palpi as in Brt/axis, second joint long, 

 clavate, third rounded, fourth elongate-oval, acute, with an apical seta.
