THE CANADIAN ENTOMOLOGIST. 25 



specimens of T. fntcmiptaria. female, expand from 26 to 30 mil. T. 

 Oc/nofuscana. female, expands 25 mil. Besides these, a number of speci- 

 mens in Mr. .Xeumoegen's collection seem intermediate between T. Escaria 

 and T. Pygmeoiaria, but 1 hesitate at present lu describe them. 



Tetracls Vidularia, Grote. 



Two female specimens in Mr. Neumoegen"s collectio]i are more brown 

 speckled about apical region and .smaller than the two typical female indi- 

 viduals. The male has not yet appeared in collections. This is congen- 

 eric with Coloradaria. 



Thamnonoma Perpallidaria Grote. 



A second male from Arizona is of a more reddish, deeper color than 

 my type from New Mexico. The species may be known by the feathered 

 antennai and the two ochre brown straight lines oit primaries arising from 

 blackish costal dots and the fragmentary s. t. line, inclining inwards. 



AZKXIA EDKXrAJA. U. S. 



Male. The infra-clypeal plate prominent. Above it a broad, frontal, 

 projected plate, the outer edge of which is roundedly scalloped instead of 

 forming three sharjj teeth as in A. Implora. As my type of Implora is a 

 female, I thought at first 1 had to do with a secondary sexual character 

 which on other grounds seems improbable. The thick labial palpi lie 

 obliquely along the face, hardly exceeding the clypeal projection. Fore 

 wings dark yellow. There seems to be no marks but a small costal dot ; 

 fringe concolorous. Hind wings fuscous. Beneath yellowish ; fore wings 

 shaded and with a fuscous subterminal band. Thorax and head dark 

 yellow ; abdomen pale. Size small like its congener. Arizona. Coll. B.
