SIX SfEW FSELAPHID.f:. 



BY CHA8. SCHAEFFER, BROOKLYN, N. Y. 



Mounting and rearranging a part of my Pselaphidse, several new 

 species were found, of wiiich descriptions of the more interesting 

 ones are given below. Our species of Batrisn.s are placed in Batri- 

 sodes by Raffray.* 



Batri.sodes beyeri n. sp.—3Tale. — Black, front of head, clypeus, palpi, 

 legs and anteuuse paler. Head, excluding the eyes, as wide as the prothorax ; 

 eyes moderate, convex; geuse feebly arcuate and feebly convergent; surface 

 slightly convex, carinte at sides indistinct; circumambient sulcus deeply im- 

 pressed, obsolete in front; foveee deep, nude; sides and front outside the im- 

 pressed line somewhat coarsely and sparsely punctate, sculpture sub-rugose at 

 sides; front strongly produced, but scarcely declivous anteriorly, lower anterior 

 maigin of the produced portion at middle with two closely placed black spines, 

 on each side of these the margin is oblique, blackish and bordered with yellow- 

 ish silken hairs; below the produced portion the surface is deeply excavate and 

 clothed with long and shorter silken hairs, which obscure more or less the sur- 

 face sculpture and partly the modifications, but there is apparently a spine-like 

 process at middle; clypeus apparently not reflexed at sides. Antennse rather 

 short and stout, slightly longer than the head and thorax; first joint stout, 

 slightly arcuate beneath, second longer and more robust than third, third to 

 eighth equal, ninth wider than eighth, transverse, tenth much longer, globose 

 and with a small rounded fovea on underside near base, eleventh as wide as 

 tenth, ovoidal, acuminate at apex. Protliorax slightly longer than wide, widest 

 before middle, apex narrower than base; median line deeply impressed and ter- 

 minating near base in a deeply impressed fovea, the tubercles on each side not 

 very sharply pointed, lateral grooves deeply impressed, the carina between these 

 and the median groove not very strong. Elytra as long as wide, humeri oblique, 

 not spinose. Abdomen as long as the elytra and as wide as base, basal carina 

 separated by about one-fifth of the abdominal width. Legs long, slender, pos- 

 terior tibiie with apical spine. Length 2 mm. 



Black Mountain, North Carolina. September. 



The female is similar to the male, from which it diifers in the 

 usual manner, by being smaller, the tenth antennal joint not as wide 

 as the eleventh, and the front of head simple, not modified ; the 

 front and clypeus are rather sparsely punctate. This fine addition 

 is dedicated to my friend, Mr. Gustav Beyer, with whom I collected 

 this and other interesting species in North Carolina, Sept., 1903.
