thorax wider than loii.u; sides strongly margined. The edge 

 finely serrate, with serrations that resenilile elongate beads. 

 Pnnetnres dense and fine. Elytra one and one-half times as 

 long as wide, with punctures dual and dense, the larger ones 

 shallow and shining at bottom. Beneatli densely punctured, the 

 ventral segments coarsely so. The anterior tibiae sim})le at 

 ai)ex. Males without modifications of prothorax or first 

 ventral segment. Length "i-.'yi) mm. Width 1 mm. Three 

 specimens. Linn Co., Oregon. G. F. Moznette. 



Cis pusillus, 11. sp. 



Elongate, oval. Piceo castaneous, shining. Antennae, 

 tibiae and tarsi ])ale. ^>stitlu•e very minute, scant and in- 

 conspicuous. Head with epistoma emarginate at middle, 

 with short blunt processes each side. <;^ntennae 10-jointed. 

 Prothorax with strong imiform punctures. Apex with slight 

 emargination at middle. Punctures of elytra dual, the larger 

 ones foveiform, shallow and shining, the smaller sparse scat- 

 tered and bearing minute bristles. Anterior til)iae slightly 

 everted externally at apex. Male with a fovea just posterior 

 to middle of first ventral segment. Length 1.40 mm. Two 

 specimens. Prof. W. S. lilatchley, Dunedin, Fla. This minute 

 species looks very unlike a typical Cis, but the difference in 

 facics is hardly of generic im})ortance. 



Cis crebberima, Mellie 



The luale has a fovea at middle of first ventral segment. 

 The species is fjuite variable in size and degree of convexity. 

 Otherwi.se the description covers the points of structure. 



Cis falli, Blatchley 



Prof. Blatchley has loaned me his Indiana types of this 

 species, which seems to be abundantly distinct. In addition 

 to the diagnostic points given in the original descrij)tion (Coleop- 

 tera or beetles of Indiana, p. 898). From a fully developed 

 male I note that the last joint of maxillary ])alpi is truncate 

 at tip and somewhat securiform. The third antennal joint is
