head is not punctate but minutely g-ranulato-reticulate and dull, the 

 l)eak rather robust, very strongly arcuate and a little longer than 

 the prothorax, densely, coarseh^ punctured at the sides. The pro- 

 thorax is nearly one-third wider than long, with the sides evenly 

 and broadly rounded, becoming parallel near the base, the apex not 

 constricted but sometimes with a short prominent carina on the 

 sides at the apical margin, the base transverse and with a very 

 small but prominent median lobe, the disk coarsely, deeply, very 

 densely sculptured in longitudinal irregularly vermiculate rugse, 

 which are in some spots broken up into coarse punctures, and 

 having a fine, more or less prominent, subentire median carina. 

 Scutellum very small, ogival and not transverse. The elytra are 

 strongly narrowed from base to apex, three-fourths longer and but 

 slightly wider than the prothorax, the apex narrowly subtruncate, 

 the disk with rather fine but deep and abrupt, remotely crenulate 

 striae, the intervals flat, wide, finely sparsely and unevenly punc- 

 tate, the yellowish elongate scales forming a large quadrate spot in 

 basal three-fifths, the most prominent feature in the pattern being- 

 two transverse bands, each consisting of tw^o uneven lunules ; else- 

 where the vestiture is very sparse and inconspicuous. Length 

 3.6-4.3 mm. ; width 1.7-2.0 mm. 



Somewhat abundant throughout the eastern and southern Atlantic 

 States. The specimens before me are from Indiana, Pennsylvania, 

 District of Columbia and North Carolina. 



ONYCHOB4RIS. 



LeCoute— Proc. Am. Phil. Soc , XV, p. 294. 



The species of this genus are characterized in general by their 

 excessively densely punctured, rather dull integuments, although 

 there are numerous exceptions having the sculpture as sparse as in 

 Baris. Onychobaris is a widely distinct and somewhat extensive 

 genus, almost exclusively restricted to the desert regions of the 

 southwest, where it replaces Baris in great measure; at least one 

 species extends as far to the eastward as the Mississippi River and 

 another is known from the true Pacific fauna, but the focal centre 

 of the genus undoubtedly lies in the dry regions of Arizona and 

 New Mexico. 



The vestiture consists of short robust semi-erect seta? as in Baris, 

 but is often so abundant, from the density of punctuation, as to 

 give to the surface a grayish-prninose a}>pearance. The generic 

 characters are stated at sufficient length in the table, and there are
