CHAMAECLEA Gr. (1883). 
Type: C. Pernana Gr. 
Allied to the genera typical of the Stiriinw vy the bulging clypeus and 
Plusia-shaped wings. Front with a slight depression, rising in the middle. 
Vestiture scaly. Tibia unarmed ; in all the examples I have seen the fore 
legs are broken off. Fore wings wide, produced at internal angle. The 
tegule are not deflected ; the thorax short. (i antennee simple. 
1. Pernana Gr. Arizona. This genus is curious for the way in which 
Chameclea Pernana mimics Chariclea Delphinii. The type is figured in 
my Illustrated Essay on the Noctuids of North America, Plate ITI.

PLAGIOMIMIOCUS Gr, (1878). 
Type: P. Pityochromus Gr, 
Front with an empty and exposed cup-shaped protuberance, the frontal 
scales being short and mossy. A. slender terminal claw on front tibia. In 
Leppert the frontal excavation is less prominent, but otherwise this species 
agrees. As compared with allied genera, the three species are slenderer 
and have a casual resemblance to the Heliothid genera Schiniaw and Ly- 
granthecia. Asin Stibadium the labial palpi are short, here they hardly 
reach the top of the more prominent infra-clypeal plate in the more typi- 
peal forms. The species are olivaceous fuscous (Pityochromus, Hupallidus), 
or of a delicate olivaceous green (Zeppert). Both Mr. Morrison and Mr. 
Smith wrongly give the fore tibise of Tepper as unarmed.

HELIOSEA Grote (1875). 
Type: H. Pictipennis rote. 
A small Heliothid allied to Heliophana and Melicleptria. It differs by 
the fore wings being more widened outwardly, and the claw to the front 
tibia being single. Mr. Smith says of it: ‘‘ Very unsatisfactorily distin- 
guished from Heliophana and probably identical with it.’’ I cannot re- 
examine my type at thé moment. When I established the genus, I was 
under the impression that the modifications of the armature of fore tibic 
gave generic characters. With the discovery of numerous Heliothid forms 
this opinion has become modified.

MELICLEPTRIA. Hubn. (1816). 
Type: M. Cardui Hubdn, 
This genus, which I took from Hubner, is equivalent to Lederer’s first 
section of Heliothis as shown by me, and, with the same type, the equiva- 
lent of Guenée’s genus Anthacia. I followed Guenée in including in it
