FAMILY II. CARABILVE. 



; eupestris Say. Trans. Amer. Phil. Soc, II. 1823, 

 II. 505. 547. 



Oblong, slender. Reddish-brown, shining : the 

 head and disk of elytra usually piceous : an- 

 tennas dusky, the two basal joints and leg* pale. 

 Thorax wider than long, narrowed behind the 

 middle ; basal impressions broad, shallow, coarse- 

 ly punctured; hind angles distinct but obtuse. 

 Elytra! striae deep: intervals convex. Length 

 4.5-5 mm. (Fig. 99. ) 



Throughout the State; common. Janu- 

 ary 6— October 5. On the wing with the 

 species of Agonoderus in early spring. 



LXXII. Tacky cellus Moraw. 3862. (Or., £ ' swift . + footed.") 



Small oblong brownish or piceous beetles, differing from allied 

 genera in having three joints of the antenna? smooth. The .joints 

 may not be entirely hairless, but lack the fine pubescence covering 

 those which follow. Both the front and middle tarsi of the males 

 have two rows of small scales (sqnamules) beneath: body through- 

 out glabrous ; elytra normally striate and with a single dorsal punc- 

 ture. Three species have been taken in Indiana, while a fourth 

 perhaps occurs. They were included with Bradycellus by LeConte 

 in his paper cited under Agonoderus. The following is the latest 

 paper on the genus :
