AMARIN.E 265 



ately converging anteriorly, parallel in about basal half, the basal 

 angles slightly obtuse or blunt; apex two-thirds as wide as the base, 

 very moderately sinuate, with somewhat blunt angles; impressions 

 very near base and apex and barely visible; foveae rather large and 

 deep, irregularly rounded, with rather coarse punctures; elytra a 

 fourth longer than wide, not two and one-half times or long as the 

 prothorax and very slightly wider, gradually ogivally rounded be- 

 hind the middle, with broadly arcuate sides; striae very fine, impunc- 

 tate, the scutellar moderate, oblique, not free; foveae of the eighth 

 distinctly and sharply interrupted medially; intervals wide, per- 

 fectly flat. Length (9) 6.7 mm.; width 3.2 mm. New York 

 (Staten Island) sodalis n. sp. 



Form oblong-suboval, slightly broader than sodalis and somewhat larger, 

 scarcely so convex, polished and brownish-black, with feeble bronzy 

 lustre, the elytra of the female not less shining; under surface shining, 

 nearly black to dark rufous; legs rufous; head much wider than long, 

 with very prominent eyes, slightly more than half as wide as the 

 prothorax, the strioles fine, only slightly oblique; antennae fusco- 

 testaceous, paler basally, notably short, barely longer than the tho- 

 racic width (9 ), but evidently longer in the male; prothorax short, 

 fully three-fourths wider than long, the sides but slightly converg- 

 ing, distinctly and subevenly arcuate from the nearly right basal 

 angles to the apex, which is almost four-fifths as wide as the base, 

 feebly sinuate, with broadly rounded angles; base becoming some- 

 what sinuate at each side; transverse impressions subobsolete; foveal 

 region slightly punctate, the inner fovea rather broadly impressed to 

 sublinear, the outer smaller, deeper and more oblique; elytra a third 

 to nearly two-fifths longer than wide, ogivally rounded in less than 

 apical half, barely wider than the prothorax, the two bases equal; 

 sides feebly arcuate; striae fine but distinctly impressed, impunctate, 

 much less fine than in sodalis, the scutellar short, oblique, free; 

 lateral series completely interrupted medially; intervals broadly 

 and feebly convex, virtually flat in the female; abdominal apex with 

 two punctures at each side in both sexes. Length (cf 9 ) 6.3-7.3 

 mm.; width 2.8-3.35 mm. North Carolina (Southern Pines), 

 Manee. Ten examples chalcea Dej. 



Form elongate-suboval, narrower than chalcea and deeper black, the 

 upper surface polished, without trace of metallic lustre; under sur- 

 face black, the abdominal tip often rufescent; legs obscure rufous; 

 elytra in the female not perceptibly less shining; head large, with 

 prominent eyes, much more than half as wide as the prothorax; an- 

 tennae short, scarcely as long as the thoracic width in the female, 

 colored nearly as in chalcea; prothorax nearly similar in outline and 

 structure throughout, with the foveal region even less punctured, the 

 inner fovea large, shallow, somewhat punctured, the outer smaller, 

 deeper, rounded, generally almost devoid of punctures; elytra not so 

 broad, similarly ogival posteriorly and even less evidently wider 

 than the prothorax; striation as in chalcea; abdominal apex with a 

 single puncture at each side in the male, two as usual in the female.
