the female is broader and sinuate medially, the sinus gradual in 

 formation. 



Platandria carolinse n. sp. Moderately stout, convex and subfusoid, 

 shining, the fine separated punctures close and more asperate on the less 

 shining elytra; anterior parts dark and uniform piceous-brown, the abdomen 

 black, the legs piceous-black ; head nearly as in the preceding, the large 

 but not very convex eyes finely faceted and at less than their own length from 

 the base; antennae rather short, slender and pale basally, gradually becoming 

 blackish and much incrassated from somewhat behind the middle, the third 

 joint very much shorter than the second, the fourth slightly longer than 

 wide, the fifth very little, the tenth fully three-fourths, wider than long, 

 obtrapezoidal, the last scarcely so long as the two preceding, stout; pro- 

 thorax transverse, very much rounded at base, the sides distinctly converging 

 from the rounded basal angles to the apex and subevenly arcuate, much wider 

 than the head and nearly as wide as the elytral base, unimpressed; elytra 

 nearly as in the preceding, the flanks not so posteriorly produced, the suture 

 more than one-half longer than the prothorax; abdomen conical, at base 

 slightly narrower than the elytra as in the preceding, finely, moderately 

 closely and subevenly punctate, the fifth tergite not quite three-fourths as 

 wide as the first and (d") with a similar strong cariniform tubercle near the 

 apex, fully one-half longer than the fourth, the edge of which is feebly sinuate 

 medially, the sixth tuberculate along the median line, the posterior edge 

 minutely sinuate medially. Length 1.65-1.9 mm.; width 0.58-0.66 mm. 

 North Carolina (Asheville). 



I took a small series many years ago at the locality cited. The 

 species differs greatly from the preceding in antennal structure and 

 in its smaller size, though the male sexual characters are very 

 similar. 



Platandria truncula n. sp. A little less stout and less fusiform, moderately 

 convex, rather paler, piceous-brown, the head and abdomen black, the punc- 

 tures fine, almost as in the preceding but much denser on the abdomen 

 throughout, the latter less shining; head nearly similar, the antennae similar, 

 except that the fourth joint, as long as wide, is more obtrapezoidal and the 

 fifth and succeeding joints more transverse; prothorax similar but shorter, 

 more transverse and fully as wide as the elytral base, the elytral suture one- 

 half longer than the prothorax, the elytra being a little shorter and more 

 transverse; abdomen at base distinctly narrower than the elytra, the straight 

 sides only feebly converging to the tip of the fifth tergite, which is nearly 

 four-fifths as wide as the first, the sixth (9) broad, gradually and rather 

 deeply sinuate apically. Length 1.9 mm.; width 0.62 mm. Nebraska 

 (Lincoln). 



The abdomen in the female throughout this genus is much more 

 feebly narrowed from base to apex and very much more densely 

 punctate, except basally, than in the male. On comparing the
