LXXII. TACHYCELLUS Moraw. 1862. (Gr., "swift + footed.") 



Small oblong brownish or pieeons beetles, differing from allied 

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

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

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

 h;ivc 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 Brady cettus by LeConte 

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

 paper on the genus:
