KEY TO INDIANA GENERA OF DRYOPHILINI. 



u. Front coxtu only moderately prominent, distinctly separated by the 

 process of prosternnm ; intermediate joints of antennae subeqnal. 



IV. Xestobium. 

 aa. Front coxa) conical, very prominent and contignous; thorax with sharp- 

 ly defined side margins; fourth tarsal joint short, emarginate. 



Ernobius. 



IV. Xestobkim Mots. 1845. (Gr., "smooth or dry + live.") 



This genus comprises two oblong, moderately stout beetles, hav- 

 ing the elytra parallel and irregularly punctate ; joints 9 to 11 of an- 

 tennae longer than those preceding; front coxfe distinctly but nar- 

 rowly separated, theprosternum short before them, and tarsi wide 

 and densely pubescent beneath. One of the tw^o occurs in Indiana. 



1G53 (5261). Xestobium eufovillosum DeG., Ins., IV, 1774, 230. 



Elongate-oblong, rather stont, parallel. Dark browu, marked with small 

 patches of sooty and yellowish hairs. AntenniE a little longer than head 

 and thoi'ax, second joint much narrower than and half as long as first, 

 third twice as long as wide, third to eighth subequal in length and gradually 

 wider. Thorax two-thirds as long as wide, margin rather broadly flattened 

 and slightly reflexed, angles all rounded; surface, as well as that of head 

 and elytra, densely granulate-punctate. Length 6-7.5 mm. 



Fall says of this species: "Rather common locally from the 

 New England States to Illinois."'" and ir^entions Indiana as one of 

 the States from which the specimens examined l»y him were taken. 

 Not seen by me from the State. 



Ernobius mollis Linn., ninth joint, of antenna' shorter than the 

 tlii'ee preceding united, ))rown, length 4-5.5 nun., is recorded from 

 Cincinnati; E. lacustris Fall, ninth joint as long as the five or si.x 

 preceding nnitod. piceous-brown, length 4.8-5.5 nnn., was described 

 from Michigan, while E. luieiptnms Lee, ninth joint equal to all 

 preceding in male, reddish or brownish-yellow, length 2.5-4 mm., 

 is known from Ohio and INIichigan. All occur on pine. 



Tribe III. ANOBIINI. 



Sjiecies of i)a.rallel and modei'ately elongate form in which, dur-' 

 iiig repose, the head is received on the under side of the thorax, 

 which is distinctly excavated for its reception; mandi!)]es not reach-
