I was wrong in following Saussure's identification of this 

 insect. Guerin^s type was from New Ireland and has the 

 second recurrent nervure incomplete. This species is 

 represented in Queensland by Scolia {Dielis) subopaca, 

 Turn., which may prove to be absolutely identical with 

 formosa ; but as I have not seen specimens of that species 

 from the typical locality it is possible that there may be 

 subspecific distinctions. Mantero (Ann. Mus. Civ. Storia 

 Nat. Genova, xl. p. 592, 1900) and Schulz (Berlin, ent. 

 Zeitschr. xlix. p. 212, 1904) refer to specimens of formosa 

 from New Guinea, but without noticing the error in 

 Saussure's identification of the Australian species. 



In addition to colour differences, whicli, though small, 

 seem fairly constant, the male tasmaniensis may be dis- 

 tinguished from radula, Fabr., and carinifrons. Turn., by the 

 length of the antennse. Compared with the length of the 

 costa of the fore wing, this is in tasmaniensis as 10 to 14, in 

 radula as 9 to 14, and in carinifrons as 5^ to 10 in milli- 

 metres. The genitalia of tasmaniensis and radula are very 

 different. The antennse of carinifrons ^ are much shorter 

 than in the other species.

Cameron's name is undoubtedly a synonym of this 

 common Mexican species.

King's name hyalina has to be retained for the North- 

 African species, having priority. The name of the well- 

 known S. American species must therefore be changed. 

 Saussure preferred to rename Klug's species kluyiij but this 

 cannot stand.
