74 THE CANADIAN ENTOMOLOGIST. 



Clypeus full, rising to a black wrinkled protuberance, circular, a little 

 depressed on top with the rim hardly raised. Wings of the usual Pliisia 

 shape, pointed at tips, and the primaries are rather broad, outer margin 

 full. 



1. Pepita Gi/e/i. ^\ est \'irginia ; Kansas. 



2. Chrysopis Gr. Arizona. 



The first species is larger, fore wings metallic, golden, with fine 

 ordinary lines ; the latter paler, smaller, with a golden lustre over sub- 

 terminal space. The relationship between this and the following genera 

 is expressed by the fine oblique lines crossing primaries. 



Stiria Grote (1874). 



Type : Stiria Rugifrons Gr. 



Eyes naked, unlashed. Front with infra-clypeal plate noticeable and 

 with a cordate impression having a raised tubercle, in the type near the 

 lower edge, and in Sulpliiirca more central. Labial paljji with third joint 

 concealed, less prominent than in Basi/oJes, from which this differs by the 

 character of the frontal excavation. Legs unarmed, tore tibiae with a 

 terminal claw. Wings wide with a Plusia-Wke tooth at internal angle of 

 primaries. Thorax somewhat short and quadrate, like Basihuh's, the 

 tegulae a little more deflected at tips-. The characters are fully given 

 Bull. B. S. N. S., 73, 1874, where I failed to note its resemblance to 

 Basilodes for the simple reason that I did not then know that genus. Both 

 species are yellow with frosted purple patches and terminal space, the type 

 larger and paler. Sulphurea intense yellow, somewhat more lustrous, 

 smaller, and the purply patches hardly frosted.

2. Sulphurea Neuin. Arizona. 



Stibadium Gr. (1874). 



Differs by the infra-clypeal plate being more prominent, the labial palpi 

 shorter. The clypeus is elevated and furnished with a moderate impres- 

 sion, more like that of Basilodes than Stiria. Like Stiria, the primaries 

 are produced at internal angle, but the wing is a little narrower, with 

 straighter costal edge than either of the other genera. The fore tibiae 

 have a terminal claw ; the eyes are naked and full. The characters 

 separating these three genera are mainly comparative, and they may be 

 optionally held to indicate groups in a single genus, which must then take 

 the name of the first genus. The type is uniformly pearly fuscous and
