differs from it in its larger size, in lacking the yellow points on 

 the dorsal region of the thorax, in not having the wings tipped 

 with brown, and in the yellow markings of the abdomen being 

 restricted to the first two or three segments, whereas A. longi- 

 tudinalis is marked from 1 to 7. The expanse of A . longiludinalis 

 is 75-78 mm., that of A. regalis 85-90 mm. 



I possess ten specimens of A. regalis taken by myself at Cook- 

 town, also a tine pair taken by Mr. Dodd at Kuranda, and one 

 taken by Mr. Allen at Cairns. The species probably extends to 

 Cape York, and specimens from that locality are much to be 

 desired, as they may show intermediate variation between type 

 A. regalis and the New Guinea A. longiludinalis. In spite of 

 the great similarity between these two species, I am inclined to 

 think that A. regalis is deserving of more than subspecific rank. 



The species is peculiar in being an exception to the general 

 rule that the Australian form is generally considerably smaller 

 than the closely allied form from Papua or the Malay Archipelago.
