The Zygenide (including the pip aie and Gilaucopides of 
Boisduval), the Chalcosiide, the Lithostide and the Arctiide form 
a natural and definite group, which is connected, by means of T7i- 
chosoma and some other genera, with the other great group, which 
contains the Liparide, Psychide, Notodontide, Limacodide, Dre- 
panulide, Saturniide, Bombycide, Cosside and Hepialide. The 
two groups, each of which may be distinguished by a name, mostly 
differ from each other by the following characters :-— 
First group. Flight very generally diurnal. Proboscis or 
maxille very generally developed. Palpi generally elongated. An- 
tenne simple or moderately pectinated. Body slightly or mode- 
rately hairy. Wings with bright and frequently with metallic 
colours or vitreous. Connected with the Hesperiide through the 
Castnit and the Cydimonii, with the Noctuites by some genera of 
Arctiide, and apparently with the Pyralttes and the Tineites by a 
few Lithosiida, and with the following group by means of Tricho- 
soma and Orgyia, &c. 
Second group. Flight very generally nocturnal. Proboscis 
very generally obsolete. Palpi very frequently short and concealed. 
Antenne most often very deeply pectinated in the males. Body, 
with a few exceptions, very hairy. Wings (excluding the Satur- 
ntide) dull or white, rarely thinly feathered or vitreous. Connected 
with the Noctuites through some genera of Notodontide, with the 
Tineites by the Psychide, and closely joined to the 4’geriide by 
means of the Cosstde, which family may also connect them with 
Depressaria and other ’Micro-Lepidoptera.
