Genus Hamotulus, Schaufuss. 



Tijds. v. Ent. xxx. p. 108. 



This genus has been created by Dr. Schaufuss for his Bryaxis 

 chamceleon from Australia; it includes Tyrus mutandus, Sharp, 

 from New Zealand, and also another new species from Australia. 



It resembles Hamotus, but it differs much in the shape of the 

 maxillary palpi; the first joint is hardly visible, the second is 

 more or less elongate, very slender at base and abruptly clavate 

 at apex; third smaller, shortly pedunculate at base and clavate; 

 fourth large, ovate, very shortly pedunculate at base, more or 

 less obliquely truncate at the. apex, and the membranaceous 

 appendage is inserted in this truncature.
