cave, shining but minutely alutaceous; elytra not fimbriate at sides, 

 the base not distinctly margined. Metasternum smooth, shining, 

 slightl}'' depressed at middle, median line fine, impressed, scabrous at 

 extreme sides with a fine, more or less obsolete line extending inward 

 behind the middle coxae. Abdominal segments shining, very minutely 

 alutaceous, especially at sides, weakly convex, very finely margined 

 posteriorly and with a fine, distinctly alutaceous line anteriorly at 

 suture, a few small but distinct granules in a transverse median line 

 at each side. Pygidium apically smooth with a few long setae around 

 the edge. Anterior femurs finely margined in front, posterior surface 

 uneven, alutaceous, a few scattered, setigerous punctures, the setae 

 very short. Middle and posterior femurs with marginal lines aluta- 

 ceous, visible from behind, surface with scattered, setigerous punctures 

 with short setae anteriorly and over apical half, three or four widely 

 placed, longer hairs along posterior edge; posterior femur about twice 

 as wide as middle femur and subequal in width to length of meta- 

 sternum. Middle and posterior tibiae without oblique ridges but with 

 longitudinal rows of tubercles along edges. Posterior tibia 2K times 

 as long as wide at apex. Tarsal joints triangular, spurs narrow, the 

 long spur about equal in length to first two tarsal joints combined. 

 Length 3 to 3.5 mm., width 1.5 to 1.7 mm. 



Type: Probably in "Naturhist. Museum, Braunschweig" or Zo- 

 ologische Museum, Berlin. 



Type locality: Konigsberg, Germany. 



Specimens examined: 21. 



Distribution: United States: New Jersey: Browns Mills, Atsion. 

 Peimsylvania: South Philadelphia. 



Season: April 28 to June 11. 



Remarks: I have no record of this species having been previously 

 recorded from the Western Hemisphere. The oldest label data from 

 the United States reads "S. Phila, Pa. 4-28-06," the most recent, 

 "Atsion, N. J., VI-1 1-45, J. W. Green." This species is slightly smaller 

 and darker than Psammodius laevipennis A. Costa and basalis (Mul- 

 sant and Rey). It is easily recognized by the club-shaped setae 

 around the pronotum.
