Macrosilia cluentius 1 ). 



Aus einem Briefe an H. Miiller. 



In Nature (vol. viii. p. 223) I have spoken of a Sphinx which, with its pro- 

 boscis of 0.25 m length, would be capable of obtaining nearly all the nectar 

 of Angrecum sesquipedale. Lately my brother, Fritz Miiller (Itajahy, Prov. 

 St. Cathariaa, Brazil), sent me the wings of another specimen of the same species, 

 and Dr. Staudinger, of Dresden, stated by comparison of these wings with the 

 Sphingidse of his collection that the name of the species is Macrosilia cluentius, 

 Cramer.
