by the same author, and as naso is the name adopted in the most 

 extensive monograph of our Rhynchophora, it is preferable to con- 

 tinue it. 



The prosternal groove is very large deep and abrupt, serving as 

 a partial shelter for the beak, which, in repose, is placed in the groove 

 with its apex extending far beyond it and resting on the flat surface 

 of the mesosternum. The strong arcuation of the beak prevents it 

 from touching the bottom of the groove however, and, at the sides, 

 it is in contact only just before the coxae, where there is an internal 

 horizontal projection, not distinctly observable in any other species.

 (Baridius) ; Proc. Am. Phil. Soc, XV, p. 298 (Pseudobaris). 



Almost exactly similar throughout to naso, but rather shorter, 

 relatively stouter, and with the interstitial punctures smaller, much 

 feebler, close-set and subtransverse. The second funicular joint is 

 fully three-fourths as long as the first and as long as the next two, 

 the club small and not longer than the four preceding joints together. 

 The prosternal sulcus is as wide and deep as in naso, but the sides 

 are straight and not broadly sinuate, there being no visible trace of 

 the internal projection just before the coxae referred to under that 

 species. Length 2.5-3.0 mm.; width 1.1-1.4 mm. 



I have seen specimens from New York, District of Columbia, 

 North Carolina and one labeled " California." Dr. LeConte evi- 

 dently limited his attention to the prosternal sulcus only, in placing 

 this species in Pseudobaris.

Similar in form, and in antennal and prosternal structure to 

 pusilla, but distinctly larger, pale red-brown in color, the elytral 

 striae finer, the intervals wider, the punctures broadly confused on 

 the second and third but forming single lines on the others, small, 

 feeble, moderately close-set and slightly transverse. The punctua- 

 tion of the pronotum varies greatly, being sometimes decidedly 

 coarse and at others quite fine; the punctures also vary in density, 

 although usually distinctly separated, and there is a narrow incom- 

 plete impunctate line, which occasionally entirely disappears, as 

 remarked by LeConte. This latter fact is however characteristic of 

 the entire tribe, when the impunctate line is not especially broad and 

 decided or cariniform. Length 3.3-3. 1 mm.; width 1.65-1.8 mm. 



Indiana, Kentucky and Wisconsin. Moderately abundant.
