G. discors, Lee. Proc. Phil. (1861). p. 341. — Elongate oval, sub-opaque, 

 black, legs rufescent; thorax faintly sculptured sides rounded, broadly mar- 

 gined, posterior angles obtuse; elytra longitudinally strigose, the striae anas- 

 tomosing; body beneath strigose, posterior coxae strigose, tibiae punctulate and 

 finely transversely aeiculate, the spurs shorter than the first joint of the tarsi, 

 the last joint of the tarsus markedly longer than the fourth. % anterior tar- 

 sal claws sinuate and elongate. % surface opaque. L. - 40 inch. 



Oregon. Vancouver's Island. (Leconte.) 



Prosternal process with a very acute carina, claws very small. 



G. lutosus, (Lee. MSS.) sp. n. — Ovate, convex, black, above bronzed ; legs, 

 epiplenrae and margins of ventral segments rufescent; thorax short, sides 

 rounded, broadly margined, posterior angles obtuse; elytra sub opaque closely 

 covered with short anastomosing strise, dorsal series visible, confused behind ; 

 posterior femora sparsely punctulate, tibiae punctate, tarsi with the last joint

Slave Lake, Kansas, Lake Superior. (Leconte.) Posterior claws

 reticulate, dorsal punctures evidently irregular, but not confused; anterior 

 tibiae rather long, spinulose; posterior coxae punctulate. tibiae with a sub-dor- 

 sal row of deep punctures. % anterior tarsi with the claw obtusely dilated. 

 L. '45 inch. 



California. (Leconte, Horn.) 



Laciniae of the metasternum sub-linear, tibial punctures confluent, 

 forming an impressed line. 



G. intersectus, (Lee. MSS.) sp. nov.— Elongate, sub-parallel, black, de- 

 pressed, above shining, slightly bronzed; thorax with the sides suddenly 

 rounded before the apex, posterior angles obtuse; elytra finely reticulate; su-
