II. rugulosus, Lee, Ann. Lye. V. 151. 



A large sub-opaque black species, differing from all our other alate 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 propleurae are finely grooved near the mai'gin and coarselj 



punctured near the coxa 1 . The elytra are finely striate, the interspaces transverselj 

 wrinkled and finely punctured. 



Length .38.-64 inch. 



California, near San Francisco. 



II. angustus, Lee., Proc. Acad. 1859, 77. 



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

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

 \ciy slightly shorter. Propleurae coarsely punctured. Thorax without thin margin. 



Length .30-.40 inch. 



Fort Tejon, California. 



II. gracilis, Bland, Proc. Ent. Soc. 1803, p. 319. 



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. Propleurae coarsely and irregularly grooved. Antenna' slender, 

 last joint longer than the preceding. 



Length .30-.35 inch. 



New Jersey, Bland. 



II. californicus, Mann., Bull. M..sr. 1843; Beitrag. p. 2s;. 



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

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

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

 are very finely wrinkled. The antennae are slender, the outer joints feebly compressed, 

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

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



Length .26-42 inch. 



San Jose, California.
