Barin.e 505 



The tubulation in the alHed species, hitherto associated with it, is so 

 brief, that it certainly would not have been made the basis for the 

 very appropriate specific name given by Say. 



The short spines and acute tubercles that appear on the proster- 

 num before the coxae in the larger and stout, coarsely sculptured 

 species of the tubulatus type, were overlooked by me in my revision, 

 as stated by Blatchley; they do not appear, however, in the minute 

 forms allied to subcalvus, or in disperses, and it is interesting to 

 note in the latter, the peculiar and extremely dense vestiture at the 

 sides of the under surface, characterizing Haplostethops and Limno- 

 baris, but here it is confined to the last three segments of the 

 abdomen. In the minute densicollis it also appears, but in a looser 

 or less compact and more erect form ; there seems to be no trace of 

 it in any other of the minute species, or in any of the larger forms 

 allied to tubulatus. 



The female appears to be smaller than the male throughout the 

 genus, less stout and sometimes with relatively shorter beak, as is 

 the case in the preceding genus, as well as Limnobaroides; this is a 

 rather singular character to be encountered in the Barinae, which 

 however, constitute a group of the Coleoptera characterized by 

 inconsistencies of all sorts. 



Stethobaris Lee. 

 The eastern smooth species of this genus can be assigned to two 

 well defined sections, one having the prothorax shouldered, that is 

 with feebly converging sides from the base, becoming broadly and 

 strongly rounded anteriorly, and the other having a more conical 

 form of this part, the sides more strongly converging from the base, 

 and feebly and not at all abruptly, if at all, more rounded anteriorly. 

 The language of LeConte (Proc. Am. Phil. Soc, XV, p. 302) "pro- 

 thorax rapidly narrowed in front, very strongly and tubularly 

 constricted near the tip," shows that the prothorax in ovata has the 

 form of the first section just noted. In regard to the interstitial 

 punctuation of ovata, the wording under the original description is 

 "with rows of small but deep punctures," and, under the subsequent 

 reference (p. 303), "the interspaces are narrow, each with a row of 

 fine but distinct punctures." All this seems to show that under 

 my description of ovata (Rev. p. 656), in stating that the inter-
