Goleopterological Notices, VII. 319 



California (Los Angeles), also said to occur in Mariposa Co. 

 There is no representative of this species in the material before 

 me, and I have simplj'- transcribed the description of Dr. Horn. 

 It is very distinct among the associates of striatopunctatus, in 

 the oblique sides of the prothorax, but seems to approach punc- 

 tatus in this respect as well as in its dull lustre. 



12. B. symiiietricilS n. sp. — Moderately ventricose, feebly shining, 

 "black, the elytra with a slightly piceous tinge. Head elongate, subtriangular, 

 the vertex smooth ; gense feebly developed, having the usual small angular notch ; 

 supra- orbital ridges well developed, the depression within the supra-antennal 

 portion deep ; antennae rather long, fully % as long as the body, very slender, 

 filiform and only just visibly thinner toward apex than at the second joint, 

 the first feebly thickened, much shorter than the next two, the seta at apical 

 fifth. Prothorax rather small, fully as long as wide, only moderately dilated 

 and very broadly arcuate at the sides anteriorly, rapidly narrowed posteriorly 

 and sinuate, the sides straight and parallel in scarcely basal sixth; base rather 

 more than l^ the maximum width but barely as wide as the head ; angles right 

 and blunt ; disk but very feebly convex, the impressions slight; side margins 

 fine and shallow. Elytra elongate and perfectly elliptical, nearly l^ longer 

 than wide, 2% times as long and 2y^ times as wide as the prothorax, the re- 

 flexed margins somewhat narrow ; disk very moderately convex, rather abruptly 

 declivous at the sides, more flattened broadly above ; strise rather fine but well 

 impressed, finely and obsoletely punctate, the first and second, and sixth and 

 seventh very irregular, the others even ; intervals moderately convex, abruptly 

 much confused in lateral fifth. Length 17.0 mm. ; width 7.0 mm. 



California (exact locality not recorded). 



The intercoxal plate of the mesosternum in the type is rather 

 abnormal, its thickened and elevated side margins posteriorly 

 being continuous vpith the bead of the acetabula,the anterior por- 

 tion, which is transversely excavated, being detached ; posteriorly 

 it is deeply sinuate as usual. In the unique male type the dense 

 pad of the first anterior tarsal joint occupies distinctly less than 

 apical half. 



This species is quite distinct from any other in elytral form and 

 sculpture.

Moderately elongate, black, shining. Head elongate, smooth; 

 gense deeply incised. Prothorax somewhat variable in form, 

 usually elongate, cordate ; sides in front arcuate, posteriorly 

 moderately sinuate ; hind angles rectangular ; margin very narrow ;
