Platynin.e 9 



form, distinctly narrower than the prothorax, the eyes notably 

 large and prominent; front with a small feeble discal indentation 

 near each eye; superciliary punctures small but distinct; mandibles 

 long and slender; palpi ferruginous; antenna? filiform, half as long 

 as the body; prothorax rather convex, very smooth, not as long as 

 wide, strongly rounded and reflexed at the sides, the latter oblique 

 and barely subsinuate basally to the broadly rounded angles; 

 anterior impression deep medially, the posterior feeble and rather 

 indefinite, the median stria fine, interrupted behind the middle, 

 attaining the base as usual; fovese deep, smooth, scarcely traceable 

 to the middle; base unusually narrow, not as wide as the apex and 

 only three-fifths the maximum width; elytra (9) one-half longer 

 than wide, not quite twice as wide as the prothorax, subinflated 

 posteriorly, the sides feebly arcuate basally; sinus long, moderately 

 oblique and very feeble; stri« smooth, very deep, the scutellar 

 coarse, subparallel; intervals strongly convex, very smooth, the 

 third with four punctures; ocellate lateral series rather coarse; 

 abdominal apex (9 ) very obtuse, with two setigerous punctures at 

 each side. Length (9) 14.0 mm.; width 5.0 mm. New York 

 (Adirondack Mts.) aesopus n. sp. 



Body very much narrower and more depressed, smooth and shining, 

 piceous-black, the under surface and legs piceous, the tibiae and 

 tarsi ferruginous; head but slightly elongate, rhomboid, the eyes 

 well developed and prominent; palpi and antennae nearly as in the 

 preceding; impressions of the front near the eyes barely traceable; 

 prothorax fully as long as wide, moderately rounded and strongly 

 reflexed at the sides, which become straight posteriorly, the angles 

 broadly rounded; surface and impressions nearly as in the pre- 

 ceding, the posterior more distinct; base very much wider, fully as 

 wide as the apex and nearly three-fourths the maximum width; 

 elytra notably narrow, nearly four-fifths longer than wide, evidently 

 less than twice as wide as the prothorax, the sides more rapidly 

 rounding basally than in cesopus, the striae and intervals nearly 

 similar, the third interval with four punctures; scutellar stria finer. 

 Male with the first three anterior tarsal joints gradually and just 

 visibly decreasing in wid-th, subparallel, the third two-thirds longer 

 than wide; male abdomen very obtuse at apex, with the usual 

 single puncture at each side; hind tarsi as in hypolithus and others 

 of the genus. Length (cf) 12.5 mm.; width 4.3 mm. New Jersey. 



rhombiceps n. sp. 



6 — Dorsal punctures of the elytra three in number. Form rather narrow, 

 moderately though evidently convex, piceous-black, shining, the 

 legs blackish, paler distally; head slightly elongate, with unusually 

 thick neck, barely three-fourths as wide as the prothorax; eyes 

 very moderate and much less convex than usual; small frontal 

 indentation at each side distinct, the pallid spots not evident; 

 antennae three-fifths as long as the body; prothorax slightly elon- 

 gate, widest well before the middle, the sides moderately rounded, 

 oblique posteriorly; base and apex equal, the angles broadly rounded; 

 surface smooth but with the usual fine transverse rugulae, the im-
