tions of Hymenoptera, he had satisfied himself of the identity of 

 the fauna of the San Diego region with that of portions of New 

 Mexico, Arizona, and south California. He mentioned certain 

 characteristic forms, particularly Haltichella and Orasema. Mr. 

 Schwarz remarked that the bulk of the insects in the delta of the 

 Rio Grande belonged to the southwestern Texas fauna. The 

 more tropical species in Texas, just as in Florida, occur in 

 island-like spots. In his paper on the semi-tropical fauna of 

 Florida, he had predicted the probable extinction of this fauna 

 by cultivation. At Lake Worth, according to recent collections 

 made there by Mrs. Slosson and Dr. Hamilton, this had already 

 been brought about. The Texas region is much smaller, and the 

 semi-tropical fauna is sure to disappear from our political boun 

 daries, he thinks, as soon as the railroad reaches Brownsville. 



Mr. Schwarz also spoke of the fact that the palmetto (Sabal 

 mexicana} is characteristic of the semi-tropical in Texas, but not 

 so in Florida, since in the latter state Sabal palmetto extends 

 far up the coast to South Carolina. A propos to this statement, 

 Mr. Howard remarked that the palmetto occurs wild at the mouth 

 of the Mississippi River, and that the finest specimens of the 

 plant he had seen were growing out of doors in gardens in New 

 Orleans, where they had not been hurt by the severe frost of last 

 winter, which destroyed orange trees in New Orleans. He asked 

 whether the palmetto does not occur along the shores of the Gulf 

 from Florida to New Orleans. Mr. Ashmead said that, in his 

 opinion, it does. Mr. Howard gave a brief account of some of 

 his experiences in south Texas north of Brownsville. Mr. 

 Schwarz mentioned the peculiar fact that in Florida the true in 

 sect fauna of the palmetto by no means reaches the northern 

 limits of the distribution of the plant. In the same way in Texas 

 the characteristic fauna of the mesquite ceases at a point far south 

 of the northern range of the plant.
