NORTH AMERICAN COLEOPTERA. 287 



short. Last joint of maxillary palpi short, ovate, slightly inijiressed. Claws 

 slightly curved, the tooth acute, moderate in size and median 9 oi" smaller and 

 iutramedian %, . Length .45 —.60 inch ; 11.5 — 15 mm. 



Male. — Antennal club slightly longer than the stem. Abdomen 

 flattened at middle, penultimate segment with a short, transverse, 

 acute ridoe near the anterior border, the last segment with the ante- 

 rior margin elevated and a ridge prolonged backwards at middle. 



Female. — Antennal club as long as the funiculus. Pygidium less 

 transverse than in the male. Tarsi equal in the sexes. 



Varlvtioxs. — As might be expected in a species with such wide 

 distribution there is considerable variation, not only in size and color, 

 but in sculpture. As a general rule northern specimens are larger 

 and more elongate, the southern smaller and more dilated behind. 

 Specimens received from northern Illinois are darker in color, the 

 elytral punctuation quite close, while in the Georgia and Texas 

 specimens the punctures are coarser and stand well apart. In the 

 northern specimens the thoracic punctuation is denser and the sur- 

 face less shining than the southern specimens. 



The southern form has been determined by Dr. LeConte as crlnita, 

 but I have shown elsewhere that Burmeister had another species in 

 view and described it well. 



This species has probably the widest distribution of any in our 

 fauna. I have seen specimens from the entire region east of the 

 Rocky Mountains and from Oregon and Washington Territory.

 reflexed, punctuation coarse, almost cribrate, with very short hair, front crib-
