Genus DORYTOMUS Germar. 



DORYTOMUS WILLIAMSI Scudder. 



A single example, in reverse, is contained in the collection. It is 

 somewhat smaller than the Scudder type and I can not be sure that 

 the elytral interspaces were hairy. The abdominal sutures are as in 

 recent Dorytomus, the first only sHghtly curved at middle. The sides 

 of the meso and metasterna are strongly granulate in the present 

 specimen (representing corresponding punctuation) this sculpture 

 also extending on to the first and second abdominal segments but 

 becoming evanescent on those following. The rostrum is shghtly 

 more arcuate than in the type figure, but this character is variable in 

 the genus. Length, excluding rostrum, 3.45 mm.; of rostrum, on 

 chord of arc, 1.75 mm. Height of body about 2 mm. 



Cat. No. 59677, U.S.N.M. 



Genus RHYSOSTERNUM Scudder. 



RHYSOSTERNUM LONGIROSTRE Scudder. 



Three specimens, all side views. Two are in fine preservation, the 

 other is much poorer. 



Cat. No. 59678, U.S.N.M. 



Genus CRYPTORHYNCHUS lUiger. 



CRYPTORHYNCHUS PROFUSUS Scudder. 



Two specimens. 



Cat. No. 59679, U.S.N.M. 



Genus BALANINUS Germar. 



BALANINUS MINUSCULUS Scudder. 



A beautiful specimen of this genus, referred here, differs slightly 

 in measurements from the type as described by Scudder. In view 

 of the known variation in modern species it does not seem wise to 

 give the present example a different name. Total length, excluding 

 rostrum, 4.25 mm.; of rostrum, along chord of arc, 2.20 mm. 



Cat. No. 59680, U.S.N.M.
