Arctiidae 
Pericopidae 
Bombycidae 
Anterior pair of abdominal feet absent. 
Nolidae (Chlamyphoridae) 
These two warts not in line, or only one wart present. 
Lithosiidae 
Euchromiidae 
Three warts present on thorax above stigmatal wart, or the 
upper one rudimentary, rarely absent, in which case wart i on 
abdomen is also'lost; legs of normal number (abdominal ones 
on segments 3 to 6 and 10). 
These three warts usually in line transversely, occasionally 
just as in the following division. 
Without dorsal “ retractile warts ” on abdominal se<r- 
ments 5 and 6. . Eupterotidae (Melalopliidae) 
Lemoniidae 
With dorsal retractile warts.. 
Lymantriidae (Leucomidae) 
The middle one of these warts posterior to the others. . 
Lasiocampidae (Lachneidae) 
Family Drepanidae. 
The species exhibit a great range in development of setae. In 
Eudeilinea we have the simple primitive arrangement, and in 
Drepana falcataria there are almost true warts. This is an 
interesting form, as it exhibits a true transition between the single 
haired tubercle of Noctuidae, etc., and the primitive wart of the 
simpler Apatelidae. It is the only instance known to me at present. 
(Compare my remarks Ann. ]ST. Y. acad. sci., vol. 8, p. 199, note 2.) 
Eudeilinea herminiata, Guen. 
I have already described this generalized form (Journ. N. Y. ent. 
soc., vol. 3, p. 68). 
Cilix glaucata, Scop. 
Thoracic region swollen, a conical elevation of the skin on joints 
3 and 4, bearing tubercle ia, the skin spines more distinct on it. 
Tail short, a thick blunt spine. Setae and tubercles rudimentary, 
i and ii distinct, the rest obscure, normal, no distinct setae associ-
