This extraordinary Erotylid has been long known to nie 

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

 collection, where it stood as Ainhlyopus testaceus, 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- 

 raerous genus like Gnathocerus. '^Die longer antenna3 in 

 this sex and the depressed clypeuSj with sinuate sides, and 

 an elevated crest in front of the eyes which invades and 

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

 the Erotylida3 before.
