interstices densely punctured and slightly rugose. Antenna; long, with the outer joints 

 compressed, very gradually shorter. 



Length .36 inch. 



California. 



JT. rngulosus, Loo., Ann. Lye. V, 151. 



A large sub-opaque black species, differing from all our other aiate species in having 

 the outer joints of the antennae compressed and shorter, and the thorax broader behind. 

 The thorax is broader than long, truncate at apex and base, sides rounded, gradually con- 

 verging to the apex. The propionic are finely grooved near the margin and coarsely 

 punctured near the coxa'. The elytra are finely striate, the interspaces transversely 

 wrinkled and finely punctured. 



Length .38.-64 inch. 



California, near San Francisco. 



II. luigustiis, Lee, Proo. Acad. 1850, 77. 



Brownish, not metallic. Thorax as long as broad, truncated in front and behind, sides 

 moderately rounded, disc feebly convex. Antennas elongate, outer joints not compressed, 

 very slightly shorter. Propleuree coarsely punctured. Thorax without thin margin. 



Length .30-.40 inch. 



Fort Tejon, California. 



II. gracilis, Bland, Proo. Eut, Soo. 1863, p. 819. 



Bronzed, sub-parallel, moderately depressed. Thorax not margined, broader than 

 long, truncate at apex and base, sides feebly rounded, anterior angles broadly rounded, 

 hind angles rectangular. Propleurse coarsely and irregularly grooved. Antenme slender, 

 last joint longer than the preceding. 



Length .30-.35 inch. 



New Jersey, Bland. 



II. oalifornicus, Mann., Bull. Mosc. 184:!; Beitrag. p. 287. 



Similar in form to gracilis, but rather more depressed and somewhat broader. The 

 surface is brownish or piccous, shining, but rarely sub-metallic. Thorax rather more 

 transverse and with a-distinct margin, more evident near the hind angles. The propleurse 

 an; very finely wrinkled. The antenme arc slender, the outer joints feebly compressed, 

 sub-equal, the; last joint broadly oval, equal with the preceding. The elytra are feebly 

 striate, the interstices fiat, smooth and very sparsely punctured. 



Length .26-42 inch,
