68 THE CANADIAN ENTOMOLOGIST. 



bluish at base ; elytra bronzed, but much less brilliant than the thorax, 

 the basal half, excepting the sutural and lateral margins and foveas, dark 

 bluish and more opaque ; body beneath dark bronze, with whitish pubes- 

 cence, which forms denser patches on the meso- and metathoracic side 

 pieces and on the sides of the ventral segments. Antennae greenish- 

 bronze, slightly more slender to tip, third joint scarcely equal to the next 

 two. Front deeply and quite regularly punctured, the punctures sepa- 

 rated by about their own diameters, callosities indistinct, pubescence 

 whitish, conspicuous. Clypeus broadly and obtusely triangularly emar- 

 ginate, angles of emargination not rounded. Thorax about one-half 

 broader than long, front margin slightly bisinuate when viewed from above, 

 anterior angles obtuse, slightly rounded, sides nearly straight, but con- 

 verging a trifle to near the base, whence they are suddenly sinuately nar- 

 rowed to the hind angles ; disc convex, regular, the punctuation deep, 

 well separated at middle, but becoming coarser and more crowded near 

 the lateral margins and at sides of base, where it appears substrigose, but 

 is scarcely confluent, median line obliterated in front, the posterior half 

 smooth and shining, not impressed nor channelled. Elytra distinctly 

 wider than the thorax, sides nearly parallel to about the apical third, 

 whence they are narrowed to the separately rounded tips, serrations fine, 

 numerous ; costa^ obliterated, except the exterior one, which is distinct on 

 the humerus and near the middle of its length, but becomes evanescent be- 

 hind ; impressions deep, arranged thus : a basal bronzed rounded one on 

 each side of the scutellum, exterior t(^ which is a shallower crescentic maik, 

 not bronzed, extending iVom just within the humeral prominence to the 

 suture. Behind this is a transverse bronzed indentation, wider externally, 

 reaching. nearly to the suture, while still posterior to this is another less 

 distinct impression, which fades gradually into the cupreous area behind 

 it. The punctuation of the elylral disc is f.iiily deep and well defined, 

 but becomes scabrous at sides and towards the tips. Body beneath 

 densely punctured, exce])t on the median area of the abdomen, which is 

 more shining. Prosternum lobed, hairy, without median smooth space. 

 Last ventral with serrulate margin, coarsely, closely jumctured, tii) with a 

 rounded emargination. Anterior tibi:« with apical dilatation about as in 

 mail, tooth of femur indistinctly serrulate, middle tibiae slightly arcuate, 

 not angulaily sinuate within, hind tibiic straight. Length, 6.5 mm. 



This species belongs in Horn's group IV., and may be i)laced near 

 mali, from which it differs by the usually small size, contrasting colours,
