202 MEMOIRS ON THE COLEOPTERA 



thorax; but in the subgenus Pisalia which does net occur at all 

 in North America so far as known, though the largest division of 

 the Leptusse in Europe they become extremely short, generally 

 but little more than half as long as the prothorax. The two fol- 

 lowing species can be assigned to Pasilia: 



Pasilia virginica n. sp. Rather slender, parallel, convex and shining, 

 pale brownish-testaceous, the elytra somewhat darker, the head blackish, 

 the fourth tergite wholly black, the legs pale testaceous; punctures of 

 the head rather large and close but shallow, of the pronotum much smaller, 

 shallow and indistinct, rather close, of the elytra larger, less close, 

 strongly asperate, of the abdomen fine, asperulate, numerous but well 

 separated throughout, the three deep and subequal impressions im- 

 punctate; pubescence short but rather coarse, pale; head nearly four- 

 fifths as wide as the prothorax, wider than long, evenly oval, the parallel 

 sides strongly and evenly arcuate, the eyes very small, at about the middle 

 of the length, formed of about 22 facets, the carinae strong and entire; 

 antennae infumate, gradually pale and strongly incrassate distally, 

 short, the second joint as long as the first, distinctly longer than the 

 third, fourth nearly as long as wide, obtrapezoidal, fourth to tip very 

 regularly and rapidly thicker and more parallel, the tenth twice as wide 

 as long, the last ogival and fully as long as the two preceding; prothorax 

 nearly three-fifths wider than long, strongly convex, with very obsoletely 

 impressed median line throughout, widest near apical third, where the 

 sides are broadly rounded, thence rather strongly convergent and less 

 arcuate to the very obtuse and somewhat blunt basal angles; elytra 

 transverse, with feebly diverging sides, at base not quite, at apex fully, 

 as wide as the prothorax, the suture equal in length to the latter, the 

 apices broadly and moderately sinuate laterally; abdomen parallel, 

 fully as wide as the elytra, the fifth tergite longer than the fourth; 

 middle coxae narrowly separated, the mesosternal process gradually 

 acute but not finely drawn out, extending beyond their middle, the very 

 free apex moderately distant from the metasternal projection, which 

 is nearly as long as wide, with its apex acutely rounded; hypomera 

 feebly inflexed, flat and fully visible from the sides. Length 1.6 mm.; 

 width 0.38 mm. Virginia (Norfolk). 



No sexual characters are clearly observable in three of the ex- 

 amples before me, but in a fourth, which is much paler in color, 

 a little stouter in form and with aii evidently larger head, the eyes 

 have nearly twice as many facets, although there are no distinct 

 abdominal modifications; this fourth specimen, which was taken at 

 the same locality, is probably the male; there are no differences 

 other than those mentioned distinguishing it from the type described 

 above.
