This species is very closely related to H. versatus Robertson 

 from which it differs in the dark, not testaceous tegulae, the 

 brownish wings, the lack of paler margins on the abdominal

 bescence, and the dark tarsi. H. versatus is a widely dis- 

 tributed and very variable species; it is therefore not safe to 

 say that the few plicae on the basal area of the metathorax of 

 H. euryceps separates it from H. versatus, although these 

 plicae are usually much more numerous in the case of //. ver-
