37O MEMOIRS ON THE COLEOPTERA 



The following is a distinct species of the bimaculata series, recently 

 taken by Mr. Beutenmiiller: 



Oberea umbra n. sp. Body parallel, feebly convex, extremely 

 slender, deep black, the entire under surface and legs deep black, the 

 anterior part of the prosternum transversely yellow, which tint pervades 

 the lateral part of the pronotum at apex, the remainder of the pronotum 

 and the entire elytra black; tarsi feebly picescent distally; pubescence 

 above everywhere minute and blackish in color, beneath longer, denser 

 and dark gray ; head wholly black, closely, strongly and unevenly punctate; 

 antennae four-fifths as long as the body, filiform, slender and deep black; 

 prothorax a little longer than wide, cylindric, closely, unevenly and rather 

 coarsely punctate, the callous spots small, embossed and polished; 

 elytra more than five times as long as wide, subparallel, slightly inflated 

 basally, at base two-fifths wider than the prothorax, sjightly shining, the 

 punctures very moderate in size, in even close-set rows, becoming con- 

 fused but not at all smaller in about apical fourth; legs short, sparsely, 

 very finely pubescent. Length 9.0 mm.; width 1.4 mm. North Carolina 

 (Black mountains). 



The type is of undetermined sex and the species is not closely 

 allied to any other known to me. 



The following is a rather distinct species of Tetraopes, which 

 may as well be made known at the present opportunity : 



Tetraopes sandix n. sp. Form stout, the size rather large, dark 

 rufous above, the entire under surface, excepting the prosternum, black 

 and extremely densely clothed with very small decumbent slate-blue 

 hairs; legs black, all the femora dull rufous, with black apex, the anterior 

 tibiae sometimes partially rufous; head rather finely, sparsely punctate; 

 antennae stout, black, the basal joint red, black at apex, the second, third 

 and most of the fourth joints very densely and uniformly clothed with 

 minute bluish-gray hairs, the first three also with short sparse erect black 

 setae; outer joints clothed with minute and dense, very dark brown hairs, 

 the base and apex of the joints with gray annuli, the last only at base as 

 usual; inferior fringe long and distinct; prothorax somewhat sparsely, not 

 coarsely punctured, rather transverse, the lateral prominence strong, 

 the umbo strong and abrupt, feebly arcuate at the sides, the four black 

 spots forming a distinctly transverse parallelogram; bristling setae at 

 the sides short; scutellum velvety-black; elytra almost twice as long as 

 wide, feebly tapering, rounded at apex, the sutural angles well rounded; 

 humeri rather prominent; surface finely, sparsely punctate and covered 

 densely with very minute decumbent gray hairs, giving a strong bloom, 

 the sparse erect hairs short and pallid; each elytron has a humeral, 

 anterior juxta-sutural and larger transversely oval post-medial black 

 spot, the post-humeral wholly wanting in specimens at hand. Length 

 14.6-16.7 mm.; width 5.0-6.0 mm. California (Witch Creek, San Diego 

 Co.). 



Two specimens, which display no sexual differences, were very
