260 THE ENTOMOLOGIST. 
saying that A (who did nothing of the sort) told him to apply to 
the keeper. The master of the keeper may hear of this and be 
naturally displeased with A (with whom he is on friendly terms) for 
attempting (as he supposes) to employ his servants. The master 
of course knows nothing of B. Now though one entomologist is, 
or should be, ready to help another to the best of his power, such 
help cannot be expected to extend to the unsanctioned use of his 
name. It has been my misfortune to have had my name used— 
more than once—in ways similar to those I have sketched above, 
and I wish to know how I am to protect myself in the future. I 
hope that I am as ready as any other entomologist to help my 
brethren, but such help cannot be taken as including the 
unauthorised use of my uame as an ‘Open, Sesame!” to 
forbidden ground—an attempt which I fear will do no good to the 
user and cause some unpleasantness for me. I should not have 
troubled you with this note if it had been a matter which only 
concerned myself, but what occurred to me has doubtless 
happened to others, and therefore concerns the fraternity at large.

An American Butrerrity. — We learn from the ‘ Ento- 
mologist,’ that our American butterfly, Danais archippus, after 
taking possession within a few years of the Sandwich Islands and 
Australia, and while making rapid conquest of the Malayan 
Archipelago, has as well invaded England, and has been taken so 
often that he seems lhkely to conquer and stay. It is rather 
difficult for the great majority of Lepidopterists to recognise him 
under the name of Anosia plexippus, but that is the name that 
the British Museum gives to what the rest of the lepidoptero- 
logical world calls Danais archippus. We suppose, after the 
English fashion (if it be not done already), he will soon be 
dubbed with a ‘common name” as well, and his identity still 
further disguised. But none the less he is an acquisition to the 
English fauna, new, larger than any of the rest of their 
butterflies, brilliant in colour, showy in appearance, easily caught, 
easily reared, novel and beautiful in chrysalis and larva, and 
withal American.—G. D. Hunst; ‘ Entomologica Americana,’ il.
