CEDEMERIDyE OF BOREAL AMERICA. 413 



in fact brownish, with a very smooth thorax and with 

 elytra not densely punctured. It probably indicates a 

 distinct species, but, as it is unique and evidently imma- 

 mature, it is passed with simple mention. 

 Two specimens, Arizona. 



Oxacis fragilis n. sp. 



Form slender, yellowish, testaceous, surface with rather 

 coarse not dense pubescence. Head sparsely punctate, 

 rather shining. Thorax as wide anteriorly as long, sides 

 in front rather strongly arcuate, posteriorly narrowed, 

 with slight sinuation, disc not densely punctate, moder- 

 ately shining, the surface somewhat irregular. Elytra 

 slightly more coarsely punctate than the thorax, moder- 

 ately closely, without traces of costse. Body beneath 

 finely punctulate and shining. Length .25-34 inch.; 

 6.25-8.5 mm. 



The last joint of maxillary palpus is distinctly cultri- 

 form, rounded at tip. The spurs of all the tibiae long 

 and slender. This species resembles some of the entirely 

 pale varieties of lacana, but the simple claws distinguish 

 it from that. 



The specimens are from Utah, Arizona, San Diego, 

 California, and San Jose del Cabo. 



Oxacis granulata Lee. New Species, p. 166. 



Slender, pale piceous or brownish. Head closely 

 punctate. Thorax slightly longer than wide, disc some- 

 what concave, closely punctate, more finely at the sides. 

 Elytra granulately punctate, without costae. Length 

 . 25-. 30 inch. ; 6.25-7.5 mm. 



The last joint of maxillary palpus is of elongate cultri- 

 form shape, acute at tip. The claws are feebly dilated 

 at base.
