To the above type belong various oriental species, 

 viz, Mel. Polysticta and Obtusa of De Haan, Mel. 

 SerricoUis, Picicollis and Coriacea of Hope, as well 

 as Pruinosa of Wiedemann, and at least a dozen 

 other nondescripts in my collection. In the Bank- 

 sian Cabinet there are two specimens named Mel. 

 Serrata ; one with the thorax serrated, the other 

 not ; and as in other respects the insects perfectly 

 resemble each other, probably it is only a sexual 

 distinction.
