54 [April, 1S44. 



Head coarsely punctured, green margined with violet behind, antennae black : 

 anterior margin of the thorax green, punctured ; metanotum coarsely punctured, 

 violet : abdomen polished, violet purple, having a green reflexion, changing its 

 position with the light : legs bright green, changing to violet above, tarsi fus- 

 cous. 



Ttphlopose pallipes. Minutely punctured, dull reddish brown, terminal 

 segments of the abdomen, antennae and mandibles, paler ; legs testaceous. 6 

 mill. long. 



Head subquadrate, narrowing posteriorly ; mandibles widest in the middle, 

 direct, with the tip incurved, inner margin coarsely serrate-dentate : pronotum 

 inflated, with an impressed mesial line: abdomen divided into three principal 

 segments, of which the first is subglobular, the second considerably larger, co- 

 nical, largest posteriorly, terminal segment of equal diameter with the preceding, 

 but twice as long, with a dark indistinct transverse band about the middle: pro- 

 vided with a sting. Found in old stumps in June. 



Eumexes substricta. Black, minutely punctured, abdominal stricture very 

 deep, with a narrow ring of yellow at the extremity of the basal segment above. 

 8 lines long. 



Head large, wings steel blue, with a small yellow spot below the base of the 

 anterior pair ; thorax lightly margined with yellow anteriorly ; tarsi fuscous. 

 Somewhat larger than E. verticalis, Say, and distinguished by the almost uni- 

 form black colour, and the base of the abdomen being fusiform, on account of 

 the depth of the incisure. 



Scaphinotus Jlammeus. Reddish brown, head slightly transversely rugose 

 between the antennas ; pronotum proportionally wider, and the profile flatter 

 above when viewed laterally than in S. elevatus : elytra coarsely punctate striate, 

 sinuate at tip, pale brilliant violet, with the margin, and several tarnished spots 

 of green. 10 lines long. 



An imperfect specimen in the cabinet of the Academy, from Marietta, Ohio. 

 Distinguished from S. elevatus by the wider prothorax and elytra, and lighter 

 colour. Not having seen a female of the latter, I am unable to point out its dis- 

 tinction from the proposed species. 



Scaritf.s substriatus. Black, shining ; antennas, palpi, and tarsi dark tes- 

 taceous : head large, nearly as wide as the thorax ; mandibles wide at the base, 

 inner superior ridge curved with two flexures, intermediate groove very wide at 

 the base : elytra wide, subparallel, convex, with 6 wide distant inconspicuous 

 strice, and a 7th submarginal one obsolete. 13 lines long. 



Scarites dlstinctus. Shining black, palpi, antenna?, and tarsi obscure tes- 

 taceous, frontal impressions profound, groove of the mandibles narrowing gra- 

 dually : elytra wider than the prothorax, slightly narrowed towards the base, 

 flattened, with 6 slightly crenate stria 3 , and a 7th obsolete, 3d with a puncture 

 near the base, another towards the extremity, and a 3d puncture at the extremi- 

 ty of the 3d interstice. 10$ lines long. II ab. Georgia 7 Prof. Hentz. 



Scauites subterraneus, Fabr. General character of the preceding, man- 

 dibular groove narrow and deep, left one continued nearly to the extremity of
