hind tarsi much shorter than the next three combined in the 

 first group of the table, longer and equal to the succeeding three 

 in the second with two to four subequal among themselves. 

 The basal impressions of the first three tergites are moderate 

 in width, rather deep, subequal and nearly always coarsely and 

 conspicuously punctured in single line. The base of the pro- 

 notum is arched over the scutellum but is sinuate from a 

 vertical viewpoint, more strongly so in the middle. Besides 

 the six American species that follow, Falagria will include 

 such European forms as sulcata Payk., and sulcatida

Elytral punctures fine but asperate and distinct. Atlantic dislrictd 2 



Elytral punctures extremely minute, sparse, not at all asperate and scarcely 

 visible; prothorax more elongate and more strongly constricted toward 

 base. SoDoran faunal districts 4 



2 — Abdominal impressions closely punctured. Form moderately stout, 

 black or piceous- black, the elytra generally somewhat paler; legs plceo- 

 testaceous, the antennae piceous-black throughout; vestiture fine, 

 short, sparse and inconspicuous; integuments polished, not at all micro- 

 reticulate at any part; head wider than long, convex, somewhat inflated 

 but, with parallel arcuate sides behind the eyes, which are moderate and 

 prominent; base broadly arcuato- truncate, the angles rounded, the sur- 

 lace minutely, sparsely punctulate, the median line flattened and im- 

 punctate except at base; antennae almost attaining the middle of the 

 elytra, moderately slender, rather distinctly, very gradually incrassate 

 distally, the second joint equal in length to the third but thicker, the 

 subapical joints not quite as long as wide; prothorax distinctly wider 

 than the head, somewhat wider than long, the sides inflated and strongly 

 rounded anteriorly, thence strongly convergent and moderately sinuate 

 to the base, which is three-fifths as wide as the disk, the sulcus deep, not 

 attaining base or apex as usual, the surface convex, finely, sparsely, 

 asperately and equally punctulate; scutellar carlnae strong, acute and 

 entire as usual; elytra moderate, about one- half wider and a fourth 

 longer than the prothorax, convex, the sutural impression behind the 

 scutellum very small and scarcely distinct, the punctures even, rather 

 close-set, the humeri widely and obliquely exposed at base; abdomen 

 parallel with the sides nearly straight, obviously narrower than the 

 elytra, finely, closely punctured, the punctures attended by flattened and 

 elongate asperities, those of the first and frequently of the second im- 

 pression coarse and notably closely crowded, generally with carinulate 

 interspaces. Length 1.9-2.5 mm.; width 0.47-0.53 mm. Rhode Island
