2O MEMOIRS ON THE COLEOPTERA. 



piceous-black, the prothorax, elytral apex and humeri and a fine apical 

 border of the basal abdominal segments pale red-brown, the legs very 

 pale; head and pronotum dull, with very fine close sculpture and obsolete 

 punctures, the elytra and abdomen with moderate asperate punctures, 

 close on the former, feeble toward the apex of the latter; pubescence 

 close, pale and evident; head large, slightly transverse, parallel, the eyes 

 rather large and convex, at somewhat less than their own length from the 

 base; antennae short and very stout, piceous, paler basally, the first 

 joint a little longer but not stouter than the second, the third shorter, 

 pedunculate basally, fourth to tenth extremely short and transverse, 

 perfoliate, between two and three times as wide as long, the last obtuse, 

 longer than the two preceding; prothorax but very slightly wider than 

 the head, moderately transverse, parallel, the sides broadly arcuate, 

 straighter posteriorly, the angles obtuse but distinct, the base rounded, 

 the surface unimpressed; elytra distinctly shorter than wide, a third 

 wider and much longer than the prothorax, the apices distinctly sinuate 

 laterally; abdomen narrow, perfectly parallel, with straight sides, much 

 narrower than the elytra, the fifth tergite fully one-half longer than 

 the fourth. Length 1.85 mm.; width 0.33 mm. North Carolina (Tryon). 



Distinct in sculpture and in the very short and stout antennae, 

 well developed head and larger eyes. 



Phloeopora adversa n. sp. Slender, nearly as in the preceding, black, 

 the elytra throughout, and the abdomen apically, pale red-brown, the 

 prothorax brownish-black, the legs brown; sculpture nearly as in liberta, 

 the asperulate punctures of the elytra and abdomen closer, the pale 

 vestiture rather coarse and longer; head well developed, wider than long, 

 the eyes moderate, at rather more than their own length from the base, 

 the tempora behind them rather less prominent, parallel and straight, 

 rounding rather broadly at base; antennae piceous-brown, paler basally, 

 short, the basal joint longer than the second, both cylindric, the third 

 shorter and obconical, fourth moderately transverse, fifth to tenth more 

 strongly and rather rapidly broader, the tenth fully twice as wide as 

 long, the last ogival and as long as the two preceding; prothorax moder- 

 ately transverse, distinctly though not greatly wider than the head, 

 rather widest and more strongly rounded at the sides anteriorly, the 

 sides thence feebly converging and nearly straight to the obtuse but 

 distinct basal angles, the base broadly rounded; elytra about a fourth 

 wider and much longer than the prothorax, parallel, moderately trans- 

 verse, the apical sinuses deep; abdomen slender, parallel, four-fifths as 

 wide as the elytra, nearly as in the preceding. Length 2.4 mm.; width 

 0.38 mm. California (Pomona, Los Angeles Co.), Fall. 



Distinguishable readily from the preceding by its more elongate 

 basal and less transverse outer joints of the antennas, rather smaller 

 eyes and larger size. 



Phloeopora jacobiana n. sp. Nearly similar to the preceding though 

 a little stouter, black, the elytra bright rufous, gradually shading to
