PTEROSTICHIKLE 355 



Sides behind the much feebler constriction notably short, the basal 

 angles obtuse, though not rounded as a rule 10 



8 Sides of the prothorax more oblique and very moderately rounded 

 from apex to the constriction. Form not very stout, convex, deep 

 black, the under surface and legs somewhat piceous-black; upper 

 surface highly polished, the elytra in the female but slightly aluta- 

 ceous; head large, nearly three-fourths as wide as the prothorax; 

 eyes rather large and prominent, the sulci parallel, deeply impressed; 

 antennae extending slightly behind the thoracic base, piceous-black, 

 gradually ferruginous distally; prothorax scarcely a third wider than 

 long, the sides finely reflexed but with thick bead; base transverse, 

 distinctly narrower than the apex, three-fourths the maximum 

 width, which is near apical third; anterior and posterior impressions 

 obsolete, the latter represented by a depression near the inner fovea, 

 as in some other species of this genus as well as in Evarthrus; inner 

 and outer foveae forming a single deep elongate concavity, the sharp 

 line of the inner curving outward at base to the outer; carina dis- 

 tinct, confluent with the margin basally; elytra oval, nearly three- 

 fifths longer than wide, a fourth (cf) to nearly a third (9) wider 

 than the prothorax, the sides arcuate, the sinus feeble, more evident 

 in the female; marginal stria fine, impunctate, submedial; striae mod- 

 erately strong, sharply incised, finely but distinctly punctate, the 

 scutellar wanting; intervals almost perfectly flat, not alternating in 

 width. Length (cf 9 ) 15.5-17.0 mm.; width 6.0-6.2 mm. Penn- 

 sylvania (Rockville), A. B. Champlain furtiva Lee. 



Sides of the prothorax less oblique, subevenly, strongly and almost cir- 

 cularly rounded from apex to the constriction; marginal stria of the 

 elytra submedial but coarser and punctate 9 



9 Body but very slightly ventricose, only moderately convex, polished 

 in the male, deep black, the legs piceous-black; abdomen and epi- 

 pleura obscure rufous; head rather large though only about three- 

 fifths as wide as the prothorax; eyes moderate, rather prominent, 

 the sulci coarsely and deeply impressed; antennae nearly as in the 

 preceding; prothorax larger, not quite a third wider than long, the 

 sides evenly and rather deeply reflexed; base feebly sinuate except 

 laterally, scarcely two-thirds the maximum width; apex distinctly 

 sinuate; transverse impressions broad and very feeble, the posterior 

 deep only in a depression near each inner fovea, the foveae coalescent 

 somewhat as in furtiva; carina united completely with the side mar- 

 gins, the angles slightly reflexed; scutellum prominently rugulate in 

 basal, smooth in apical, half; elytra elongate-oval, nearly two-thirds 

 longer than wide, only a fifth wider than the prothorax; sides evenly 

 arcuate, broadly reflexed, the sinus broad and very feeble though ob- 

 servable; striae rather coarse, deeply impressed, strongly and rather 

 closely punctate, the scutellar short, forming a fine bipunctured line 

 behind the ocellate punctures; intervals strongly convex, subequal, 

 the seventh toward base becoming prominent, the ridge ending at 

 the omoplate; humeri rounded and not denticulate. Length (cf ) 

 17.8 mm.; width 6.6 mm. Florida sulcata n. sp. 



Body much more ventricose but not very stout, convex, deep black, shin-
