I have fonnd apparently the caterpillars of the same s})e- 

 cies, bnt failed to rear them, at the following places on 

 Oahn, and always on Wilistrocmia: October 25, 1914, on the 

 ridge back of Alewa Heights; April 30, 101 '>, on Waialae 

 jSTui ridge; July 9, 1916, on the east side of Ml. Kaala near 

 the top. The caterpillars are fonnd on their food-plant in the 

 daytime, a different habit from the other species so far as 

 known. Having a tree for food-plant is also an unusual halnl 

 for the moths of this kind in Hawaii.

 by Dr. Wm. Kerr of the U.S.S. ^'Kainbow", on French Frig-
