Superfamily Nocrutna. 
Tubercles all free, iv. remote, moved up behind the spiracle, 
except inthe Thyatiride, where this tendency is counteracted by 
the development of a secondary tubercle behind iii.; setz single or 
transformed into warts. Includes the families Notodontide, Thy- 
atiridxe, Dioptide, Geometridae, Brephidze, Drepanide, Agaris- 
tide, Noctuidae, Cymbidz (—Nycteoline of Hampson), Litho- 
siide, Pericopide, Arctiide, Huchromiide (—Syntomide of 
Hampson, Zygzenide Kirby), Lymantriide, Eupterotide and 
Lasiocampidee.* 
In a small section of this group the primitive first larval stage is 
wanting. As several of the families intergrade, not representing 
dichotomous divisions in the line of descent, the families of the 
larvee do not corroborate those of the moths completely. The 
following synopsis will give some idea of how the characters 
run, though it is not exhaustive. Further study may develop 
a better. arrangement. The matter is not simple, as the species 
are numerous.
