 of thorax slightly rounded, rather strongly margined, posterior angles not 

 acute; elytra finely and closely reticulated throughout, appearing punctulate

Pennsylvania, Lake Superior. (Leconte.)

 c. (1853), p. 159.— Ovate, sub-parallel, sub-depressed, shining, black, above 

 greenish bronzed, antennae, legs and epipleura rufescent; thorax with the 

 sides straight, finely margined; elytra very finely and lightly reticulate, the 

 areolae small (the intersections are deeper and give the appearance of a fine 

 punctuation); the dorsal punctures evident, confused behind; prosternal pro- 

 cess broad, rather convex, the mesosternal emargination rounded and short; 

 posterior femora and tibiae smooth, spurs short, last joint of tarsi longer than 

 the fourth. % tarsal claws simple. L. "28 inch. 



Sitkha, Vancouver's Tsland. (Leconte, Horn.) 



This is determined from a typical specimen sent by Maklin; but 

 Mannerheim's description is not very applicable. His A. irregularis 

 however, suits exactly. 



G. lugens, Lee. Ann. Lye. v., 203.— Broadly ovate, rather depressed, black, 

 above faintly bronzed, elytra with a very faint yellow lateral spot beyond the 

 middle; thorax with the sides straight, rather broadly but not strongly mar- 

 gined ; elytra closely and very finely reticulate, the areolae extremely small, 

 the dorsal punctures well marked, rather irregular, but not confused at the 

 apex; posterior coxae faintly punctulate, tibiae with a sub-dorsal row of deep 

 punctures. % tarsi with the claws simple. L. -38 inch. 



San Diego. (Leconte, Horn.) 



G. suturalis, sp. nov. — Regularly ovate, black, above slightly bronzed, 

 sub-opaque; thorax with the sides hardly rounded, posterior angles rectangu- 

 lar; elytra closely reticulate, the sutural region nearly smooth, dorsal punc- 

 tures evident, irregular, the yellow spot beyond the middle is but little 

 evident; body beneath strigulose, posterior femora obsoletely punctulate, tibiae

ANISOMEKA. Brulle, H. N. V., p. 205. (Type bistriata.) 



Thorax coarctate behind (as in Carabidse), prosternum convex, 



metasternum hardly emarginate, but with a shallow groove in front, 



laciniae broad, sub-triangular, episterna reaching the coxal plates ; legs 



long, femora narrow, elongate, tarsi elongate, last joint of posterior
