THE CANADIAN ENTOMOLOGIST. 165 



FLORIDA APHORURID^. 



[The following letter was communicated to me by Dr. Leonhard Stej- 

 neger, U. S. National Museum, through Mr. E. A. Schwarz. It is of 

 particular interest, giving new localities for two species and adding one to 

 our faunal list. Alex D. MacGillivray] : — 



During my sojourn in Florida, 1892-93, I happened to collect some 

 small insects, CoUembola, of the family Lipuridse. As I suppose very 

 little, if anything, is known about the representatives of this group from 

 that country, I presume every little contribution to the knowledge must be 

 of a certain interest, and I thus take the liberty of writing you this letter. 

 I have found three species, and my friend, Dr. H. Schott, who is a specialist 

 in this matter, has assisted me in classifying them. The first species is 

 the small white Lipiira^ itierviis, TuUberg, easily recognized as entirely 

 wanting anal spines (" sj>i?ia'. anales "). It was known before this from 

 Sweden, Finland, Sumatra and California, and probably from Germany 

 and Italy. Thus it is widely distributed, but it must, anyhow, be very in- 

 teresting to have it ascertained from a place so far distant from the other 

 ones as Florida. In that State I found it twice. Both times it was 

 walking about on top of the water at the border of a small lake not far 

 from Clarhana, on the Orange Belt Railroad, in Orange county. 



The second species is Anurida Tullbergi, Schott. It is a good deal 

 larger and blackish with a faint blackish tint. Characteristics for this 

 species are that the " organa postantennalia'' show not less than 24-28 

 small rays or corpuscles (even called "tumors" and "elevations," but 

 I do not find those terms expressive). Till this time, strange to say, it is 

 only recorded from Sweden and Finland. I found it at the same place 

 and living together with Lipura inermis. 



The third species is Amcrida tna}-itima, Laboulbene, with only 7-8 

 shorter aiid thicker corpuscles in the organa postantennalia and three of 

 the same kind in the tip of the antenna, which Dr. Schott calls antennal 

 organ. This species is already known from the Swedish West Coast, Eng- 

 land, France and North America. I hardly think from Florida, though, 

 till I found it on Key West. When walking along the shore, turning over 

 stones in the water and looking for Blenniids and other fishes,*! suddenly, 

 under a piece of lime rock, not far from the hospital, found a great num- 

 ber of this little insect. It was high, or at least rising, tide, and they were 



*I have changed this name to Aphorura, Lipura being preoccupied. See Can.
