44 WOODPECKERS IN RELATION TO TREES. 
THE SENNA FAMILY (c.ESALPINACE^E). 
Two of the 12 native species of trees of this family are attacked by 
sapsuckers, and one of them at least is much disfigured. One West 
Indian species also is punctured by the sapsucker. 
LIST OF OESALPINACE^E ATTACKED. 
Water locust {Oleditsia aquatica). — This tree is very commonly 
attacked by sapsuckers near Longbridge, La., and swollen girdles are 
produced similar to those figured for the honey locust. 
Honey locust (Oleditsia triacanthos) . — Near Longbridge, La., 
nearly every tree is attacked by sapsuckers and protruding girdles are 
usually formed. One tree (fig. 5 and PL IV, fig. 3) was remarkably 
deformed, having shelflike girdles, some of which extend halfway 
around the tree and project 4 inches. 
Logwood (Hxmatoxylon campechianum) . — Bahama Islands, Moore. 
THE PEA FAMILY (FABACE^). 
Ten arborescent species of this family occur in the United States, 
of which two are known to be attacked by sapsuckers. 
LIST OF FABACE.E ATTACKED. 
Locust (Robinia pseudacacia) . — Randolph County, W. Va. (F. 
73108). 
Sonora iron wood (Olneya tesota). — Arizona (A. M. 1«54).

THE MAHOGANY FAMILY (MELIACEJE). 
The single native tree of this family, the valuable mahogany, is 
attacked by sapsuckers. 
Mahogany (Swietenia mdhogani). — Dr. Hopkins obtained speci-

on one of the Florida Keys has numerous pecks in the hark (A. M. 141), 
TIN-: SPURGE FAMILY (eUPHORBIACE^).
