purplish-brown, with the reniform stigma normal, the orbicular 

 long and narrow, outlined with black and joined to the reni- 

 form ; and the claviform very long and sword-shaped, the 

 sword having a hilt. Hind wings and abdomen very white. 

 So far as I can ascertain, the capture of no second specimen has 

 been established, and this can only be looked upon as an 

 accidental introduction. It is decidedly a South European 

 species, occurring in Southern France, Spain, and Sicily. 

 At Gibraltar Mr. J. J. Walker says of it, " Found occasionally 

 on the Rock at ivy-bloom in October ; also met with in 

 February. It is, however, more plentiful among coarse grass 

 and herbage on the eastern beach (of the Mediterranean) 

 three miles north of Gibraltar, in October. Some very richly 

 marked specimens were seen on the Tangier sandhills in 

 September 1888." To its limited European range may 

 therefore be added some portion of Northern Africa and 

 probably a large extent of Asia, since it is well known to be 

 plentiful in India. That it is a resident in any part of the 

 British Isles is altogether improbable.]

 part of the antenna threadlike ; pale brown. Palpi short,
