214 Dr. Fritz Miillcr's Notes on 



progenitor of the group, and that it has been but recently 

 transmitted to the females of Thyridia. 



Subfamily 2. Satyrin^. 



The males o^ Antirrltcea Archcea have highly-developed 

 odoriferous organs, and emit a strong odour ; there is a 

 most elegant mane of pale buff hairs on the under side of 

 the front wings, and opposite to it the hind wings bear an 

 odoriferous spot, which has caused a considerable modifi- 

 cation of the neuration of the Aving.* A second much 

 smaller odoriferous spot exists in the angle between the 

 submedian and internal nervures. 



In the allied genus Pierella no trace of odoriferous 

 organs could be found nor any odour perceived. 



Subfamily 4. MoRPniNiE. 



The wings of the males are known to be generally 

 provided with tufts of hairs or with spots of peculiar 

 appearance, Avhich probably will prove to be odoriferous 

 organs. The only genus, the wings of which are deprived 

 of such organs, is Morplio. In compensation the males 

 of all the species of Morplio which I have caught 

 (il/. Hercules, Epistrophis, Adonis, Cytheris, Menelaus, 

 Achilles^ are able to protrude from the end of the abdomen 

 a pair of hemispherical bodies covered Avith short hairs, 

 which produce a very distinct odour. In the splendid 

 M. Adonis and the allied M. Cytheris this odour is most 

 agreeable, resembling vanilla. 



Subfamily 5. Brassolin^. 



Pencils of hairs, capable of being erected voluntarily, 

 or spots of peculiar scales are present on the hind Avings 

 of most genera. Their position varies much, even within 

 the limits of the same genus. In the males of various 

 species of Caligo, Dasyophthalma and Opsiphanes, I 

 found that very distinct odours were emitted by these 

 pencils or spots, the odour being particularly strong in a 

 species oi Dasyoj)hthabna. 



* See Bvfler, Catal. Srxtyrid. Br. Mus. 1809, PL V. fig 3. In Butler's 

 figure of the mane (" plaga pectinatim cirrata") the liairs apjicar to be 

 directed backward, while tlie contraiy is the case ; they are inserted along 

 the submedian nervure and directed forward.
