 apical half whitish. 



I have found apparently the caterpillars of the same spe- 

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

 Oahu, and always on ^Yil•stroemia: October 25, 1914, on the 

 ridge back of Alewa Heights; April 30, lOl'i, on Waialae 

 Xui ridge; July 0, 1916, on the east side of Mr. Kaala near 

 ilie top. The caterpillars are found 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 habit 

 for the moths of this kind in Hawaii.

Described from a male and female reared from two small 

 caterpillars found on plants of Boerhaavia tetrandra, collected 

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

 ate Shoals, October, 1914. These caterpillars were fed on Por- 

 tidaca oleracea and grew to maturity, and pupated on Jan- 

 uary 5tli and 14th respectively. The moths appeared on Jan- 

 uary 20th and February 8 th.
