on the wing. Aside from the general statement made by Delaporte 
de Castelnau and Gory, and by D. Ramon de la Sagra (3) who says 
“Segun M. Laporte, este insecto causa grandes destragos en los limon- 
eros, ” the specimens of the writer are the only ones reared from Citrus. 
Conclusions 
Clytus devastator, a Cerambycid borer, was first described as a serious 
pest of Citrus in Cuba in 1836, and has since been recorded by collectors, 
besides in Cuba, at Key West, Chase, Paradise Key and Palm Beach 
on the East Coast of Florida, and at Perico Island, close to Anna Maria 
Key, at the mouth of Tampa Bay on the West Coast of Florida. It 
has been reared from “ Cuban mahogany/’ pomegranate ( Punica 
granatum) and Citrus (orange), and, according to Mr. E. A. Schwarz, 
has as its preferred host the common mangrove ( Rhizophora mangle). 
Aside from the original statement that it was a serious pest of Citrus 
in Cuba, it has not been reared from Citrus until it was found damaging 
orange trees on Perico Island, Florida, in the spring of 1910. It has 
demonstrated its capacity to become a serious pest in Florida, and with 
the extension of the citrus industry still further south into more trop¬ 
ical portions of the state, or with a rearrangement of its host relation¬ 
ships following further development of the country, it may assume an 
important role as a pest of Citrus.

adults and the burrows of the more mature larvse in the roots, but also the frass- 
plugged channels made in the sapwood by the younger larvse. Note that secondary 
fungus attack has caused a discoloration of the sapwood near the burrows.
