PHALACRID/E 49 



fuscous, the legs pale; head moderate, not quite half as wide as the 

 prothorax, sparsely and rather finely but deeply punctate, broadly 

 trapezoidal, with rounded angles at apex, the eyes well developed, 

 the facets smaller than in the preceding and mutually contiguous; 

 antennae rather long, the funicle slender; prothorax much more than 

 twice as wide as long, with strongly arcuate converging sides from 

 base to apex, the flat basal bead rather wide, distinct; scutellum 

 ogival, only moderately transverse; elytra fully two and one-half 

 times as long as the prothorax, broadly parabolic posteriorly, dis- 

 tinctly longer than wide, very highly polished and smooth through- 

 out, barely at all reticulate even at the extreme tip, the punctures 

 fine but evident, forming widely separated and very regular series; 

 metasternal process very broad, arcuato-truncate at apex and very 

 finely beaded, the mesosternum showing slightly on the antero- 

 lateral slopes. Length 1.8-2.7 mm.; width 1.1-1.45 mm - Rhode 

 Island to Florida and westward to Duluth, Minnesota. One speci- 

 men from Colorado Springs seems identical. Extremely abundant 

 and widely diffused, the series at hand including more than seventy 

 examples. [Phalacrus pallipes Say] pallipes Say 



10 Elytra posteriorly, and especially on the flanks, having fine and close- 

 set, short, irregularly longitudinal scratches, which become subreticu- 

 liform at the extreme tip. Body elongate-oval, gradually rather 

 narrowly rounded behind, black, the under surface and legs ferru- 

 ginous; head moderate, not one-half as wide as the prothorax, 

 finely and sparsely but rather distinctly punctate, the antennae 

 normal, with the third joint equal in length to the next two; pro- 

 thorax slightly more than twice as wide as long, the strongly con- 

 verging sides somewhat strongly arcuate, the basal bead evident; 

 scutellum rather broadly ogival, obtuse; elytra much longer than 

 wide, two and one-half times as long as the prothorax; serial punc- 

 tures very minute, the surface smooth; metasternal process broad, 

 the mesosternum distinct at its sides anteriorly. Length 1.75-2.5 

 mm.; width 1.05-1.28 mm. Utah (southwestern), -Weidt. Seven 

 examples fallaciosus n. sp. 



Elytra polished as usual but, on the flanks, there are very short, fine and 

 somewhat close-set sublongitudinal scratches, nearly as in fallaciosus 

 but very much finer and more restricted to the flanks. Body smaller, 

 narrowly oval, varying in color from piceous-brown to pale brownish- 

 yellow above, always pale beneath; head about half as wide as the 

 prothorax, of the usual form and with very minute sparse punctula- 

 tion; antennae well developed, of the usual form, the third joint 

 nearly as long as the next two combined, the first joint of the club 

 much longer than the second; prothorax unusually long, three-fourths 

 wider than long, the converging sides feebly arcuate, the basal bead 

 distinct; scutellum slightly transverse, sharply ogival; elytra much 

 longer than wide, slightly more than twice as long as the prothorax, 

 the apex moderately obtuse; second stria short, serial punctures 

 extremely minute, becoming larger and slightly lunate very near the
