Larger and more elongate, and with finer and more nearly erect 

 elytral setae than in any of the nearly related forms of Nomidus. It 

 is closest to pallidiis, but that species has the prothorax stouter and 

 more coarsely sculptured, the pronotal channel generally broader and 

 deeper, the alternate elytral intervals more prominent, and the even 

 ones with sparser and much stouter setae. In the female of longus 

 the depth of the body at the metasternum is about half the length of 

 the elytra ; in the stouter female of pallid ns, this depth is more than 

 half the elytral length. 



PANSCOPUS (NOMIDUS) BAKERI, n. sp. 



Length, 6-7.6 mm ; width, 2.4-3.7 "''"''' the females longer and 

 stouter than the males. Scales dense, distinctly striated. Derm black, 

 prevailing color of scales cinereous and brown, the pale scales, es- 

 pecially those in the serial punctures of the elytra, often more or less 

 tinged with silvery or pale greenish blue, the brown scales often 

 obscure aeneous and grouped into irregular and asymmetrical elytral 

 brown markings that tend to form oblique bars, some specimens 

 dark, more rarely nearly uniform cinereous ; rostrum with a usually 

 distinct median carina (it may be covered by scales) and occasionally 

 faint lateral ones : antennal scape setose and scaly, reaching middle 

 of eye ; pronotal channel usually broad and deep apically, narrower 

 and shallower, or sometimes obsolescent, in basal half, rest of surface 

 rugose-tuberculate ; sutural (except basally) and alternate elytral in- 

 tervals costate, and with a crowded, in places double, row of blunt 

 setae, the even intervals without setae except second along middle 

 third of its length in some females. 



Rostrum stout, feebly arcuate, somewhat more than twice as long 

 as thick, about as long as prothorax, much thicker and wider apically, 

 upper surface in profile plainly discontinuous with front, densely 

 scaly and sparsely setose except on and behind the well-defined nasal 

 plate, the surface from about apical third to apex usually lightly con- 

 cave, more broadly and deeply so near apex, the median carina usually 

 rather broad and conspicuous basally but finer or obsolescent beyond 

 middle ; interantennal fovea, when present, rather coarse and groove- 

 like ; interocular fovea often groovelike, and frequently produced 

 backward onto the head as a very fine groove or smooth line, which
