these two names have been treated as one species in recent 

 British literature. 



Walker's synonymy must therefore be looked upon as one 

 of the many quite groundless references made by him, and the 

 synonym removed from devastatrix. 

 Mamestra tincta Brahm. 



This name appears in Smith's 1903 Check List (No. 1996), 

 on what authority I am wholly at a loss to discover. It is a 

 well-known European species, common in the British Isles. It 

 bears some resemblance to our purpurissata, though that has a 

 still nearer old world ally in advena Schifif., of which Stau- 

 dinger lists purpurissata as a North American variety. But 

 whereas our species has male antennae strongly serrate-fas- 

 ciculate, almost pectinate, both tincta and advena have them 

 ciliate merely. 



The Occurrence of the Australian Cattle Tick and 



the Brown Dog-tick in Key West, Florida 



(Acarina, Ixodoidea). 



By F. C. BiSHOPP, U. S. Bureau of Entomology.^ 

 The finding of specimens of the Australian cattle tick, Mar- 

 garopus annulatus australis Fuller, on native cattle in Key 

 West, Florida, by Mr. G. A. Runner, of the Bureau of Ento- 

 mology, is not only of interest but also is deserving of considera- 

 tion from an economic point of view. These ticks were taken 

 on cows in the city of Key West on February 8, 1912. They 

 were examined by the writer and found to be identical with 

 the form of cattle ticks which occurs in the West Indies, Cen- 

 tral America, Australia and other parts of the world, but 

 which has not been previously taken in the United States. 



In 1 90 1 Salmon and Stiles' reported the occurrence of this 

 tick in Porto Rico, and in 1909 the writer found it to be a 

 severe pest of live stock in the vicinity of Tampico, Alexico.'
