COLEOPTERA OF BAJA CALIFORNIA. 375 



have securiform terminal joints. Spinola has described 

 them very correctly (Clerites, pt. 2, p. 3), thus, "last 

 joint of each of the same form and nearly the same size, 

 slender, conical, and truncate." Lacordaire also states 

 that the antennae have eleven joints, but this has been 

 properly corrected to ten by LeConte. 



Petalium brunneum n. sp. 



Elongate, brownish, opaque, sparsely clothed with 

 short fulvous pubescence. Head coarsely and closely 

 punctate. Thorax broader than long, narrowed in front, 

 a slight sinuation each side in front of middle, disc con- 

 vex, with an oblique impression each side in front, surface 

 rather coarsely and closely punctate. Elytra with the 

 two outer striae entire, the sutural extending one-half 

 from apex, the other striae represented by rows of punc- 

 tures which are coarse and subquadrate near the base, 

 and become gradually finer and indistinct toward the 

 apex, the intervals punctulate. Metapectus rather coarsely 

 punctate. Abdomen finely and closely punctate. Length 

 .06 inch. ; 1.5 mm. 



P. bistriatum Say., the only other species known, is 

 larger, piceous, with extremely feeble elytra! sculpture, 

 and with the lateral and sutural striae by no means as well 

 impressed. San Jose del Cabo. 



Cerotoma Chev. 



Cerotoma furcata Oliv. Ent., vi, p. 643, pi. iii, fig. 50. 



In a review of the species described by Olivier I stated 

 that this could not be a synonym of trifurcata, as given 

 in the " Catalogus." Later, in my synopsis of Galeru- 

 cini (Trans. Am. Ent. Soc, xx, p. 129), I accepted this 

 view. Recently specimens have been collected by Mr. 

 E. A. Schwarz near Brownsville, Texas, agreeing per-
