North American Species of Trorjophloeus. 345 



distance of those in morio, and it may be distinguished from all 

 the others of this portion of the group by its finer and denser 

 elytral punctuation. 



The legs are paler in some specimens, of which the type is one, 

 being reddish-brown ; this character should therefore be used 

 with caution, and only when confirmed by large series of speci- 

 mens. 



19 T. maiicus n. sp. — Moderately slender, black ; legs dark piceous 

 brown ; antennee piceous, apex of first and base ot' second joints paler ; 

 pubescence short, fine, rather dense ; integuments shining. Head four- 

 fifths as wide as the prothorax, feebly convex, minutely and densely 

 punctate ; prominences rather small and feeble ; antennae slender, 

 longer than the head and prothorax, very slightly incrassate ; joints 

 two or four decreasing in length, the latter distinctly elongate, tenth 

 slightly longer than wide ; eyes very large and coarsely granulated, 

 prominent; tempora very short, one-fourth as long, obtusely subangulate, 

 not prominent. Prothorax fully one-half wider than long, widest at 

 anterior two-fifths, where the sides are rather broadly rounded, thence 

 almost equally and rather strongly convergent to base and apex, and 

 very feebly arcuate in the latter sense; base broadly feebly arcuate, two- 

 thirds as wide as the disk, much narrower than the apex; the latter 

 truncate; apical angles obtuse, not distinctly rounded; basal obtuse and 

 slightly rounded; disk distinctly impressed, finely and densely punctate, 

 the punctures separated by less than twice their widths, and becoming 

 rather abruptly slightly larger and closer with the surface strongly, 

 finely reticulate near the sides. Elytra quadrate, a little wider and one- 

 half longer than the prothorax, scarcely perceptibly impressed near the 

 suture, except a very feeble mutual impression at the base, somewhat 

 coarsely but feebly punctate, the punctures separated by nearly twice 

 their own widths. Abdomen much narrower than the elytra, parallel ; 

 sides nearly straight; border rather thin and deep; surface minutely 

 reticulate, the reticulations almost granulose, also minutely and rather 

 sparsely punctate. Legs slender, short as usual. Length 2.5 mm.

This species was identified as memnonius Er. by M. Fauvel, 

 but it probably differs in the antennas, which are described by 

 Erichson as being a little shorter than the head and prothorax ; 

 here they are distinctly longer. 



20 T. §pectatus n. sp.— Very slightly more robust, black; legs 

 and antennae very dark brownish-piceous, the latter scarcely paler at 

 base; pubescence short, very fine, and rather sparse; integuments shin- 

 ing. Head fully four-fifths as wide as the prothorax, nearly flat above,
