PLATYNIN.E 37 



Prothorax subcordiform and similarly narrow but with the basal angles 

 more or less distinctly defined, though not always sharp at tip, 

 obtuse as a rule 15 



15 — Elytra slightly less shining than the anterior parts, due to micro- 

 reticulation. Upper surface moderately convex, deep black, the 

 thoracic reflexed sides diaphanously paler; under surface and legs 

 piceo-rufous; head scarcely longer than wide, nearly four-fifths 

 as wide as the prothorax, with large and remarkably prominent 

 eyes, the anterior impressions short, deep and parallel; antennae 

 long, slender, piceo-ferruginous throughout, about half as long as 

 the body; prothorax nearly a third wider than long, the broadly 

 and strongly reflexed sides broadly rounded, becoming oblique but 

 not sinuate basally, the angles very obtuse though with the tips 

 finely acute and prominent; base arcuate laterally, as wide as the 

 apex, both beaded as usual; apex feebly sinuate, with obtusely 

 rounded angles; surface with feeble transverse rugulae, medially 

 smooth, becoming evidently punctulate in the foveal region, the 

 impressions evident, the posterior very feeble; foveae very large, 

 with the deepest part at some distances from the sides; elytra two- 

 thirds longer than wide, nearly twice as wide as the prothorax, the 

 apices gradually very oblique, with the sinus long and very shallow; 

 striae rather coarse and groove-like, minutely punctulate along the 

 bottom; intervals feebly convex; met-episterna very long, as usual 

 in this section; anterior male tarsi only moderately dilated. Length 

 (d^) ii.o mm.; width 4.0 mm. Connecticut (S. Meriden), — -H.

Elytra polished in both sexes 16 



16 — Elytra with four dorsal punctures. Body rather small, moderately 

 convex, very highly polished, testaceous throughout, the head and 

 pronotum slightly obscure, except at the broadly reflexed thoracic 

 sides, the elytra black, but with diaphanous reflexed edges; head 

 narrow and elongate-rhomboidal, with somewhat narrow neck and 

 moderate though slightly prominent eyes, three-fourths as wide as 

 the prothorax, the short anterior impressions wide and shallow; 

 antennae very slender, more than half as long as the body; prothorax 

 a fourth or fifth wider than long, the sides broadly rounded, oblique 

 posteriorly, becoming gradually just visibly sinuate, the angles 

 obtuse, with rather blunt but evident tip; base arcuate, slightly 

 wider than the sinuate apex having rounded angles; impressions 

 feeble; foveae large, deep, sparsely punctulato-rugose, extending 

 forward beyond the middle; elytra oblong, with parallel arcuate 

 sides, one-half longer than wide, about twice as wide as the pro- 

 thorax, rather abruptly obtuse at apex, with moderately oblique, 

 long and rather deep sinus; striae nearly smooth, rather deeply 

 impressed, the intervals notably convex, the four punctures coarser 

 than usual; legs and tarsi slender. Length (9) 8.5-9.5 mm.; 

 width 3.4—3.5 mm. Pennsylvania (Allegheny), — Hamilton. Three 

 examples parmarginatus Ham.
