 The butterflies of this beautiful group have been removed 

 by Boisduval, Blanchard and Guenee to the Sessiliventres. 

 Guenee's remarks on this subject (Uran. et. Phal. vol. i. pp. 

 1, 2, 3 and 4), like everything that accomplished entomolo- 

 gist has written, are deserving the most attentive study, but 

 to me they are unconvincing. M. Lucas, in a paper just 

 published in the ' Annales de la Societe Entomologique de 

 France,' has made some observations on Urania Rhiphseus 

 which are of great interest, and which my friend Mr. Double- 

 day, with his usual kindness, has copied for me as follows: — 

 " It appears that this species, placed by Latreille with the 

 Diurnes, and arranged on the contrary with the Nocturnes 

 by Boisduval and Blanchard, is not very uncommon in the 

 environs of Tananarrivo: it reposes on the leaves of the 

 Mango, and is then not very difficult to capture. According 

 to the authors who have described the metamorphoses of this 

 splendid insect, the caterpillar is spiny, and is furnished with 

 two retractile tentacles on the first segment ; it feeds on the 

 leaves of the Mango, and changes to a pupa attached by the 

 posterior extremity." These characters seem to point to an 

 affinity between the Cydimonii and the Detegentes suspensi ; 

 but the characters here noticed require confirmation : if 

 correct they seem to disturb all arrangements hitherto pro- 

 posed.
