This genus diifers from Cijmatophora in the short, i)road, more or less 

 scalloped wings and simple antennte. From Tiqilnoski. it differs in the 

 simple antenna; and larger, broader, shorter wings. From HeinerophUa, it 

 may be distinguished by the simple anteniuE and less scalloped wings. In 

 coloration, tlie species are dull ash-gray, with an indistinct, regularly-curved, 

 extradiscal line and four discal dots. The markings resendjle those of 

 Tephrosia (7'. nnficaria) more than any other genus, but the species want 

 the distinct dark lines. The single species known tVom this countr}. occurs 

 in Colorado, none having been tbund, as yet, east of the great plateau, or 

 plains. It is nearly, but not very closely, allied to the European G. piillata, 

 but is more reddish-ash-colored.
