 Albofasciatus, Sm., is certainly a synonym of tricolor, 

 Westw. If the species noticed by Andre under the name 

 of albofasciatus proves to be distinct it will have to receive 

 a new name. The position of the ocelli in the female of 

 A. tricolor is marked by shallow punctures.

 suggest the above name in its place.

 Var. Thynnus nigrofasciatus, Sm., 1. c, n. 38, $. 



Nigrofasciatus, Sm., seems to be merely a colour variety. 



This species approaches the Australian sub-genus Lep- 

 teironc, but has the hypopygium narrow and slightly pro- 

 duced and the second cubital cell less strongly narrowed 

 on the radial nervure.
