AMERICAN COLEOPTERA. 173 



limule and the marginal line is also very slender and may be inter- 

 rupted in some specimens. The middle band is straight, oblique 

 and of uniform width throughout. 



Dr. Horn identified specimens of this variety as prcetextata under 

 which name it is found in some collections; the insertion of the 

 name prcetextata in Mr. Fall's list of the beetles of So. Cal. is based 

 upon this erroneous determination and it should read californica. 



I include with californica provisionally the specimens from S. W. 

 Texas, which have a similar middle band, although the marginal 

 line is entire. Dr. Horn has pointed out that the fauna of the Cape 

 region is allied to that of Mexico and Cent. Amer., and californica 

 is apparently the extreme form of circumpicta in the direction on 

 which these Texas forms have started. 



Severa group. 



Thorax convex, sides rounded ; interocular strise few and very coarse, head behind 

 and between them finely wrinkled ; elytra % convex, 9 much flatter. 



Thorax almost smooth severa. 



Thorax transversely strigose, deeply so at sides striga.

Habitat. — Fla., La., Tex., N. Mex. Prof Wickham records the 

 occurrence of this species at Point Isabel, Texas, on the beach with 

 paniphila. It is, he says, " a most extremely wary species, of very 

 "strong, swift flight, and was met with rarely. It flies in the hot- 

 " test sunshine." 



Dark green or almost black, beneath green ; elytral markings con- 

 sist of a white submarginal dot and a complete apical lunule. In 

 some specimens there is an additional submarginal white dot, repre 

 senting the terminal part of the humeral lunule. Head nearly pol- 

 ished, deeply striate beside the eyes, strise few in number and 

 coarsely cut; between them and behind the eyes the head is finely 

 wrinkled, not hairy ; labrum th ree -toothed ; thorax scarcely rugose 

 at the sides, almost polished, convex, rounded at the sides, slightly 

 constricted behind, impressions not very deep ; elytra near base 

 sparsely but strongly punctured, towards the apex more obsoletely, 

 with a row of foveolce near the suture, apex serrulate ; elytra con-
