stiff hairs, mixed with a slight powdery exudation; head much nar-

Miworevs [ Helopinee]. 
Caput retractum ; elypeus fronte confusus, apice emarginatus. Oculi trans- 
versi, distantes. Palpi mavzillares securiformes; labiales triangulares. 
Mentum antice latum, basin versus angustatum. Antenne breviuscule, 
art. tertio longiore, 4-7 brevioribus obconicis, 8-10 latioribus et com- 
pressis plus minusye obconicis, 11 rotundato. Prothorax transversus, 
ad latera rotundatus, antice angustior, basi bisinuatus, apice fortiter 
emarginatus. Elytra ovata, prothorace latiora, humeri angulis pro- 
thoracis obtecti. Pedes mediocres; tibie apicem versus crassiores, cal- 
caratee ; tarst antici breves, postici elongati tenues. Prosternum pro-

In the character of its antenne this genus is nearer to Misolampus 
and its allies than to Helops, with which it agrees in habit. In 
this respect, however, it still more nearly resembles some species of 
Amara. 
Mimopeus amarordes. 
M. glaber; capite prothoraceque nigris, nitidis; elytris purpureo-brunneis, 
punctato-impressis, subtilissime granulosis; antennis pedibusque ferru- 
gineis.
