 To this genus, as I now understand it, belong several apociesJ, 

 which I publisheil under the genus Malitchim ; such Jia tcmii-

TILL US Fab. 



T.?' TERMiN.\TUS. — Black; terminal joint of the antennae a- 

 long as tlie head and thora.K. 



Inhabits United States. 



Body black, densely punctured and with numerous cinereous 

 hairs : eyes reniform, emargination very prufnund : antonna>, 

 radical joint suboval ; second joint globular ; third, fourth, fifth 

 and sixth, very short, transverse, approximated ; seventh, eighth 

 and ninth, rather larger, serrate ; terminal one greatly elongated, 

 longer than the head and thorax, and about three times as long 

 as all the preceding joints conjunctly, much compressed, linear, 

 with dense minute black hairs, tip and base rounded : labrum 

 rounded at tip: mandibles bifid at tip : thorax cylindrical, hardly 

 narrowed at base, margin rufous : tarsi distinctly five articulate ; 

 first joint longer than the second ; penultimate one bilobatc : 

 nails dentated : abdomen sanguineous; terminal segment black. 



Length rather more than one-f lurth of an inch. 



I obtained two specimens of this curious insect, at the [161] 

 cantonment of Major Long's party near Council Bluff on the 

 Mi.s.souri river. It occurs ulso in Indiana and Penn.sylvania. 



By the form of the tarsi, palpi and thorax, it approaches the 

 present genus ; but the extraordinary conformation of the an- 

 tennae seems to require a separation from the other species, ut 

 least in a distinct subgenus.
