Described from a considerable number of both sexes troin 

 various sources. It is very common apparently all over India, in 

 hills and plains, and occurs probably in all parts of the Orient. 

 The actual dates recorded run from March to October, but in 

 Java at least it seems to occur during the winter also. Originally 

 described from China. The Uij>es of miticetus, Walk., and anttdotus. 

 Walk, (both males, from China), in the British Museum, are un- 

 doubtedlv normal m-vorum. As noted years ago in manuscript by 

 Major Austen, a d of fnlvipes, Macq., in the Bigot collection is 

 identical, and agrees with Macquart's description.
