This extraordinary Erotylid lias been lon^- known to me 

 from a male and female I obtained from Mr. G. Waterhouse's 

 collection, where it stood as Amhliio2ms testaceuSj Lac, with 

 which, however, it lias nothing to do. While the female 

 presents no peculiarities beyond those of some ordinary 

 yellow Triplacid, the male conveys the idea of some Hetero- 

 merous genus like Gnathocerus. The longer antennse in 

 this sex and the depressed clypeus, with sinuate sides, and 

 an elevated crest in front of the eyes which invades and 

 almost divides them, are unlike anything I have met with in 

 the Erotylidse before.
