The Zyganida (including the Procrides and Glaucopides of 
Boisduval), the Chalcosiida, the Lithosiida and the Aretiidce form 
a natural and definite group, which is connected, by means of Tri - 
chosoma and some other genera, with the other great group, which 
contains the Liparida , Psychida, Notodontida , Limacodida , Dre- 
panulida, Saturniicla , Bombycida , Cossida and Hepialida . 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 
maxillae very generally developed. Palpi generally elongated. An- 
tennae simple or moderately pectinated. Body slightly or mode- 
rately hairy. Wings with bright and frequently with metallic 
colours or vitreous. Connected with the Hesperiida through the 
Castnii and the Cydimonii , with the Noctuites by some genera of 
Arctiida , and apparently with the Pyralites 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. 
Antennae most often very deeply pectinated in the males. Body 
with a few exceptions, very hairy. Wings (excluding the Satur - 
niida) dull or white, rarely thinly feathered or vitreous. Connected 
with the Noctuites through some genera of Notodontidce , with the 
Tineites by the Psychidce, and closely joined to the AEgeriidce by 
means of the Cossidce , which family may also connect them with 
Depressaria and other Micro -Lepidoptera.
