 one to three pale, dentate crossbars. Antennae reddish-brown, their form 

 as in Mcolor, but slightly longer. Thorax cylindrical, one-half longer than

Eyes emarginate in front, coarsely granulated; maxillary palpi 

 cylindrical ; last joint of labial palpi dilated, scarcely transverse ; 

 tarsi short, apparently 4- jointed, claws simple. Two species are 

 known from within our faunal limits, one of which is found in 

 Indiana,
