DESCRIPTIONS OP NEW SPECIES. 195 



color is singularly bright ; the sculpture of the elytra is curious, 

 being composed of large closely placed punctures, so shallow as 

 to appear obliterated. 



CAULICHROM A LATK. (emend. SEKV.). 



515. C. cobalt in urn. Laete cyaneum, prothorace transversim minus 

 rude rugoso, antennis pedibusque nigris, femoribus posticis abdomine- 

 que ferrngineis. Loug. 25 36 mm. 



Cape San Lucas, Lower California. Related to the Texan G. 

 plicatum Lee., but the transverse ruga? of the prothorax are not 

 so coarse, the anterior transverse constriction more regular and 

 stronger, the color of a beautiful blue (not green), and finally the 

 front and middle thighs are black. 



SCH1ZAX LEC. 



Body elongate, clothed with short coarse pubescence, flying 

 hairs sparse at the base of the antennae and legs ; head rather 

 small, front short, deeply impressed transversely ; mandibles 

 obtuse and subemarginate at tip, though the outline is concealed 

 by the pubescence ; gena? short, rounded ; eyes large, finely 

 granulated, broadly divided, lobes nearly equal in size, rounded 

 triangular ; palpi stout, short, last joint truncate, impressed ; 

 antenna? ( ) twice as long as the body, ? about one-third longer 

 than the body, slender, punctured, and pubescent, with a few 

 flying hairs near the base, llth joint longer, slightly curved at 

 the tip in both sexes. Prothorax narrowed in front and behind, 

 with an acute lateral spine one-third from the base. Scutellum 

 moderate in size, elongate, triangular, acute ; elytra parallel, 

 broadly rounded at tip. Prosternum broad between the coxae, 

 which are not angulated externally ; mesosternum broad, protu- 

 berant, truncate behind, coxal cavities open externally ; metas- 

 ternuni with side pieces rather broad, scent pores distinct.

 hind pair longer; hind thighs $ extending to the tip of the 

 elytra ; hind tarsi with the 1st joint, as broad as, and equal to, 

 the two following united.
