may be only a seasonal form of the well-known C. inadagas- 

 cariensis. 



There has been much difference of opinion respecting the 

 tailless insect with the head of a Butterfly, originally figured by 

 Drury under the name of Fapi/io rliipJicus, and said to come 

 from Chma. It is usually regarded as a broken specimen of 

 C. madagascariensis, or an allied form, with the head of one 

 of the Eqititidcc attached ; but as we now know that at least 

 some species of the latter Family mimic species of Ahidis, Hiib- 

 ner (Moths belonging to the Sub-family Nyctalemoni7ice, which 

 are closely allied to the Cydimojiincc)^ it does not appear to be 

 quite impossible that an anomalous Butterfly agreeing with 

 Drury's figure may yet be discovered. 



SUB-FAMILY II. NYCTALEMONIN^. 



Egg. — Not described. 



Larva. — With sixteen legs, not hairy, but with short, conical 

 tubercles on each segment, bearing short bristles. 



Pupa. — On the ground, among leaves. 



Imago. — Of large size, and with broad wings, the hind-wings 

 dentated and tailed, the longest tail traversed by the upper 

 median nervule. Flight diurnal. 



There are but two genera of this Family, one, A/cidis, 

 Hiibner, confined to the Moluccan Islands from Amboina to 

 Australia,* while the other, Nyciakmon, Dalman, has a wider 

 extension, from India and China to Australia. The species of 

 AUidis are blue-black Moths measuring four inches across the 

 fore-wings, which are crossed by two green bands, the inner- 

 most broadest ; the hind-wings have one broad central band, 



• The .illcgcd occurrence of A. zoJiuia, Duller, in China must be con- 

 iidcrcd very doubtful.
