and coupled with a development in Tenebrionidse, more like that of the 

 Sonoran region than that of the Atlantic coast. The total absence of the 

 carrion eating Silphidas is apparently well established, as well as a character- 

 istic development of certain genera and tribes, like Leucocera in the Chryso- 

 melidae, Exophthalmini in the Rhynchophora and Solenopterini in the Longi- 

 cornia. 



Mr. Leng said the data were insufficient to attempt any comparison with 

 the fauna of South and Central America, beyond the evident intimate relation 

 between that of the islands and the continent and the comparative paucity of 

 species on the islands. In reference to Florida he spoke of the West Indian 

 colony in southern Florida and the existence of boreal forms like Chlccniiis 

 nigcr in Florida and Cuba, the presence of which might be accounted for if 

 one might assume a former land connection between the two regions. 



Mr. Leng also called attention to the changes in family names, necessary 

 to accord with the most recent catalogues, viz. : 



Cicindelidse become part of Carabidte 



Trichopterygidse change to Ptilidse 



Mycetophagidse change to Tritomida; 



Trogositidae change to Temnochilid^El 



Parnidse change to Dryopidae 



Dascyllidffi part change to Dascillidse 



Dascyllidse part change to Helodidae 



Elateridffi part change to Eucnemidae^ 



Throscidas change to Trixagidse 



Lampyridae split into Lycidas, Lampyridae, Telephoridae 



Ptinidae split into Ptinidas, Bostrichidae 



Lucanidae split into Lucanidae,3 Passalidae 



Cistelidae change to AUeculida; 



Anthicidae split into Pedilidae, Anthicidae, Hylophilidae 



Calandridae change to Cossonidae 



Scolytidae split into Platypodidae, Ipidae 



and said that he hoped to discuss the reasons advanced for each change at a 

 later meeting. 



These remarks were discussed by Dr. Osburn and Dr. Lutz, the former 

 calling attention to the great depth of water in the Florida Straits, the latter 

 vigorously combatting the possibility of such a land connection, as lacking 

 support from palaeontology, geology, botany or any other science. The evi- 

 dence he said was strong that West Indian distribution between the islands 

 and from the mainland had been a matter of sea-drift, winds, hurricanes and 



1 The name Ostomidae is preferred by some authors. 



•2 The Elateridas have been subjected to further subdivisions, in part, per- 

 haps, still open to discussion. 



3 The Lucanidas and Passalidae are by some authors treated as sub-families 

 of Scarabaeidae, which is then split into a number of sub-families.
