much narrower and not over a third as wide as the metasternal. 

 The punctures of the elytral series are, on the upper parts of the 

 disk, rather more distant and decidedly more feeble than in politus. 

 It appears to be very rare. 



PHAI.ACROPSIS n. gen. 



Mentum trapezoidal, truncate at apex. Maxillary palpi with the last joint 

 slender, subcylindrical, minutely truncate at apex, slightly narrower than the 

 third, and nearly twice as long. Antennae slender ; third joint as long as the 

 next two together ; club slender, the ninth joint fully as wide as the tenth and 

 slightly longer, eleventh narrower, elongate-oval, and slightly shorter than the 

 two preceding. Prosternal process moderate in width, very feebly concave, 

 inflexed, not ciliate at apex ; metasternal pi-ocess broad, fully three times as 

 wide as the prosternal, projecting to the anterior limits of the coxal cavities, 

 where it is transversely truncate, the truncation very feebly arcuate, the apical 

 bead very fine in the middle, thickened at the lateral angles, and again fine 

 along the coxal cavities. Legs short and very robust ; spurs of the posterior 

 tibiae slender, equal, nearly parallel, projecting distinctly beyond the spinose 

 fimbria ; the corresponding tarsi but very slightly longer than the anterior, 

 nearly as in Phalacrus, with the basal joint less than one-half as long as the 

 second. Pronotum without trace of basal bead in the middle. Scutellum 

 large. Elytra not at all striate, having a very fine sutural bead, the fine stria 

 being continuous with the basal stria along, and almost touching, the scutel- 

 lum ; discal stria entirely obsolete. 



The single species forming the type of Phalaeropsis, is quite 

 peculiar in form, being decidedly more elongate-oval and just per- 

 ceptibly more depressed than in the various forms of Phalacrus. 

 Although remote, it is the nearest ally of Tolyphus in our fauna, 



P. dispar Lee. — Bull. U. S. Geol, Survey, V, No. 3, p. 513. — Castane- 

 ous, evenly elongate-elliptical, fully three-fourths longer than wide, convex, 

 polished. Head rather small, evenly rounded at apex throughout its width, 

 very minutely sparsely and obsoletely punctate. ProtJiorax at base more than 

 twice as wide as the head, polished, without trace of reticulation, very minutely, 

 rather sparsely but distinctly punctate ; base transverse, feebly sinuate at each 

 side of the scutellum. Scutellum large, about twice as wide as long, ogival, 

 very obsoletely finely and sparsely punctate. Eli/tra nearly three times as long 

 as the prothorax, not narrowed behind, broadly, evenly rounded at apex, 

 polished but having very indistinct traces of minute wavy reticulation, which 

 becomes more evident and confused near the sides and apex ; punctures lunate, 

 arranged in rather poorly-defined distant series, the intervals with more con- 

 fused punctures which are nearly equal to them in size, rather large but feeble, 

 much larger, denser and more confused at the sides, where they are very 

 broadly crescentic. Legs and under surface pale testaceous, sparsely, coarsely 

 pubescent. Length 3.0 mm.
