256 REVISION OF THE THYNNID^E OP AUSTRALIA, II., 



Hab. — Fremantle, W.A.(Walker). Type in British Museum. 

 This is a very distinct species, and may prove to be generically 

 distinct when the female is discovered. 



This Part includes the whole of the remainder of the Austra- 

 lian Thynnidse at present known. With one or two exceptions, 

 I have refrained from describing females of which the males are 

 unknown, considering that such descriptions would not be in the 

 interests of science. The females are so frequently taken with 

 the males, that the names given to them would soon have to be 

 sunk, whilst the difficulty of certain identification in the Colonies 

 would be much increased. 



Where nothing to the contrary is mentioned, the types of the 

 new species are in my own possession, and will be presented to 

 the British Museum. 



I exclude from the family the genus Anthobosca, which I con- 

 sider to be more nearly related to Myzine. 



The South American species of Thynnidce, with the exception 

 of Aelurus, seem to belong to different genera from any Australian 

 forms. Two species described as Tachypterus by Weijenberg 

 seem to me to be more nearly related to Scotaena, and do not 

 belong to the Diammince. 



Cameron* has recently described a new genus, Adontothynnus, 

 from S. Africa, but the characters he gives are those of Anthobosca. 

 He has been misled by Ashmead, who states that the maxillary 

 palpi are five-jointed in Anthobosca, and has not consulted Guerin's 

 description.
