AMERICAN COLEOPTERA. 77 



viewed directly from above; a basal triangular black spot on each 

 side equally distant from scutellum and angles, larger than the apical 

 s-pot but not joining the margin. The scutellum is velvety black. 

 The elytra are cliithed with brownish black hair with short lines of 

 velvety black rather irregularly placed. At the middle of the elytra 

 and common to both is a moderately wide crescentic band (of which 

 the ends are obtuse) with the concavity forwards ; extending three 

 fourths of the width of each elytron, and clothed with silvery white 

 hairs. Body beneath densely punctured and sparsely clothed with 

 short cinereous hairs. 



This species appears to be rare in Canada West. For two fine 

 specimens in my cabinet I am indebted to Mr. Johnson Pcttit, of 

 Grimsby, Ontario, to whom I take pleasure in dedicating it, as an 

 evidence of appreciation of the services he has rendered science in the 

 investigation of the fauna of his neighborhood. 



Lichnanthe Edwardsi, n. sp. — Body black, head and thorax greenish metal- 

 lic, elytra pale brownish testaceous. Head densely and coarsely punctured, 

 Thorax as broad as long, sides rounded in front, sub-parallel behind, base 

 rounded, disc densely and coarsely punctured except at the hind angles, and 

 rather densely clothed with long black-bi'own hairs. Elytra longer than their 

 conjoined breadth, brownish testaceous, rather coarsely and densely punctured, 

 and sparsely clothed with short black recumbent hairs. Body beneath black, 

 faintly metallic and sparsely clothed with hairs. Abdomen more shining very 

 finely punctured and with fewer hairs ; the last two segments are brownish 

 ferruginous. Legs black, femora and tibise hairy. Length .62 inch ; 15.5 mm. 



The elytra are contiguous along the anterior three-fifths of the 

 suture then strongly divergent. It may be known from all our spe- 

 cies by the hair of the thorax being long and black, the hair of the 

 under surface is somewhat paler and very much less dense. The last 

 joint of the maxillary palpi is very distinctly excavated as in Dasj/dera, 

 and by the increase of the number of species the diflferences between 

 it and Lichnanthe appear to be vanishing. 



For the unique in my cabinet, I acknowledge great indebtedness to 

 Mr. Henry Edwards, of San Francisco, to whom I take pleasure in 

 dedicating it. Occurs in '• Oregon" without more specific designation 

 of locality. 



Serica elongatula, n. sp. — Castancous, or testaceous, brown, elongate oval ; 

 ^ides parallel; sub-opaque, faintly sericeous. Head rather densely punctured 

 in front, sparsely on the vertex, clypeus faintly emarginate, angles broadly 

 rounded, margin rcflexed. Thorax convex, neither coarsely nor sparselj' punc- 

 tured, rather mofe than twice broader than long, sides strongly rounded and 

 fimbriate with long hairs. Elytra elongate sub-parallel, fimbriate on the m.^ir- 

 gin, very convex transversely, faintly striate and with punctures irregularly
