SliS FAMILY XMJI. PTTNIMO. 



legs not received in cavities; antenna: 1 in repose resting loosely upon 

 the front coxa 1 , usually 11- jointed, the three outer joints more or 

 less dilated and elongated. Two genera are probably represented 

 in Indiana.

(i. Front coxa* only moderately prominent, distinctly separated by the 

 process of prosteruum ; intermediate joints of antennae snbequal.

aa. Front coxae conical, very prominent :ind contiguous; thorax with sharp-

ERNOBIUS. 



IV. XESTOBIUM 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- 

 tenna? longer than those preceding; front coxa? distinctly but nar- 

 rowly separated, the prosternum short before them, and tarsi wide 

 and densely pubescent beneath. One of the two occurs in Indiana.

Elongate-oblong, rather stout, parallel. Dark brown, marked with small 

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

 and thorax, 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 Eughiiul States to Illinois,"' and mentions Indiana as one of 

 the States from which the specimens examined by him were taken. 

 Not seen by me from the State. 



Erir.ib'ntx ntollis Linn., ninth joint of antenna? shorter than the 

 three preceding united, brown, length 4-5.5 mm., is recorded from 

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

 preceding united, piceous-brown, length 4.8-5.5 mm., was described 

 from Michigan, while E. h<l< i/x/mis Lee., ninth joint equal to all 

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

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



Tribe III. ANOBIINI. 



Species of parallel and moderately elongate form in which, dur- 

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

 which is distinctly excavated for its reception; mandibles not reach-
