occurred July 2S, the second August 0, the third August 10 to 11, and the fourth August 20 to 22. 
Eiley has found the larva as late as in October, the moths in March, April, and June.

brown in hue. 
Dr. Dyar lias kindly lent me a colored sketch of Walker’s type of Jl, thyatiroides in the 
Oxford ^Museum, received from Colonel Swinhoe, There seems to be little doubt but that it is my
