A specimen of this species in the Nat. Museum has pinned on it a 

 printed slip, cut from a journal, which reads as follows : " On the 25th 

 of May, I obtained from the Wakarusa bottom a large number of very 

 small larva? that were feeding upon the Waahoo, Euonymus atropur- 

 pureus. These caterpillars were so small when fully grown that they 

 escaped through the wire-topped cage and made their cocoons in the 

 corners of the room, and, ten days later, they hatched and were captured 

 as they flew in the windows. This is the moth which I have named the 

 Waahoo moth, Hypononicuta loakariisa.''^ Across the face of the slip is 

 written " G. F. Gaumer." 



I have nine males, no females, of inultipiinctclla.

This differs from the preceding only in lacking the gray shading. I 

 have seven females, no males, of orbiviaciilella. Both forms, bred from 

 Euonymus americanus, Dept. Agriculture, No. 3406, will doubtless prove 

 to be sexes of one species as determined by Walker.
