290 MEMOIRS ON THE COLEOPTERA 



Head distinctly larger, a third to two-fifths as wide as the prothorax. . .6 

 6 Body elongate and narrower, very nearly twice as long as wide in the 



male _ 7 



Body stouter, much less than twice as long as wide in either'sex 9 



7 Hind tarsi (cf ) longer, distinctly longer than the tibiae. Body elon- 

 gate-rhomboidal, rather convex, very obscure uniform opaque olive- 

 green above, with a narrow reddish marginal stripe on the elytra, 

 attaining the sutural angles only very narrowly very exceptional 

 character and without the least pallidity on the disk; pronotum 

 with a single marginal bilobed pale spot before the middle; head 

 shining, greenish-cupreous, the medial ridge parallel, not apically 

 modified, the clypeal horn longer than wide, with its sides slightly 

 converging to the truncate apex; prothorax but little wider than long, 

 evenly convex, the apical umbo rather prominent; elytra cuneiform, 

 the apex three-fourths as wide as the base; surface with partial series 

 of very fine punctures; pygidium shining, feebly metallic-green in 

 basal, abruptly testaceous in about apical, half, everywhere with 

 close-set transverse and confluent strigilation; under surface and 

 legs metallic green but not very intense, the parapleura, partially, 

 femora and median impressed line of the abdomen testaceous; each 

 abdominal segment is cuprascent at apex, the sixth testaceous at 

 apex; anterior tibiae slender, the upper tooth small and obsolescent; 

 hind tarsi moderately thick and compressed. Length (cf) 20.5 

 mm.; width n.o mm. A single example from the Levette collection 



labeled "Indiana" longula n. sp. 



Hind tarsi (cf ) much shorter; body smaller and still narrower 8 



8 Outline (cf ) elongate-rhombiform, the hind body long and cuneiform, 

 moderately convex, the upper surface obscure green and opaque, the 

 sides and apex of the elytra with a sharply defined tawny margin, 

 sometimes slightly prolonged forward near the suture and with the 

 region about the scutellum faintly brownish; pronotum with an 

 entire tawny external margin; head with the medial ridge slightly 

 acuminate apically, the clypeal horn broad, not quite as long as wide, 

 parabolic to subquadrate; prothorax but little narrower than the 

 elytra, rather short, wider than long, the sides nearly straight 

 throughout, or only so toward apex, having a feeble axial paler 

 wisp on the basal lobe, the apical umbo very moderate; elytra almost 

 twice as long as the prothorax, the apex scarcely more than two- 

 thirds as wide as the base, sometimes having a few extremely minute 

 scattered punctules; pygidium with the darker basal part rather 

 nubilous, the uneven strigilation unusually sparse, becoming short 

 and very sparse apically; under surface in great part testaceous, the 

 sterna medially and the tarsi dark and metallic green; anterior tibiae 

 with the feeble upper tooth at a great distance from the second; hind 

 tarsi unusually short, scarcely more than three-fourths as long as the 

 tibiae. Length (cf) 18.0 mm.; width 9.75 mm. Virginia (Norfolk). 



Two examples angustula n. sp. 



Outline (cf ) nearly similar but with the hind body rather less cuneate and 

 with the elytra more rounded at apex, dark opaque green, the sides 

 and apex of the elytra, prolonged anteriorly slightly on the disk,
