Eljtra more coarsely deeply and sparsely punctate ; antennae 

 stouter ; anterior tibiae of the male shorter, thick, narrowed 

 near the base and less than twice as long as the tarsi, the latter 



more dilated failTeli 



Pronotum more finely feebly and much more sparsely punctured ; 

 discal parts of the elytra more or less indefinitely clouded with 

 a paler rufescent tinge. 

 Elytra shorter, with the sides very strongly divergent, coarsely, 

 very sparsely punctate; abdomen with five exposed segments; 

 border very wide ; size larger, the form broader — 9-

Elytra longer, the sides less divergent ; punctures finer and more 



abundant ; abdomen with scarcely more than four exposed 



segments; border narrower — 9 nul>ilatll8 



Sides of the prothorax oblique and feebly sinuate behind, the base 

 relatively wider ; small species, pale flavescent in color, the punctua- 

 tion fine and sparse ; elytra small, much shorter than wide ; tarsi 



longer and more slender (lebilis 



Pronotum without trace of an impressed median line, almost similar in the 



male and female ; body intense polished black throughout. California. 



Tempora rounded but rather prominent and subrectangular ; prothorax 



wider than long ; punctures smaller and closer ; last joint of tlie 



antennae much longer than the tenth temporalis 



Tempora very convergent and broadly rounded, not at all prominent ; 

 prothorax not distinctly wider than long, nearly as in Orobanus but 

 more convex ; punctures strong and sparse ; last joint of the antennae 

 only just visibly longer than the tenth ; last joint of the maxillary 



palpi smaller IlUIUIJOldtiailllS 



Prothorax transverse, nearly as in Anthophagus, the sides but feebly conver-

 hind angles ; last joint of the maxillary palpi short, subulate ; posterior

G. 'brunneus Say. — Touru. Ac. Phila., Ill, p. 158 ; verticalis Say : Trans. 

 Am. Phil. Soc, IV, p. 4tJ3 ; ctvsus Er. : Gren. Staph., p. 853. 



It is somewhat remarkable that Erichson should have failed to 

 recognize in his ceesvs the species described by Say as brunneus, 

 for the cloud of black near the apex of the tergum, in connection 

 ■with the size of the body — slightly under a quarter of an inch or 

 6 mm. — is very characteristic of the species. Verticalis is prob- 

 ably a smaller female specimen, the great difference in form of the 

 male and female prothorax possibh' not having been noticed by 

 Say.
