 ber of years was Secretary of the Pacific Coast Hardware and

lie was an ardent student of nature, taking up Botany as 

 his special study. He became a member of the Academy of 

 Sciences, and for many years he was Secretary of the Botanical 

 section. He did much valuable work in the local field, having 

 under his charge the Herbarium of the Academy of Sciences, 

 and adding to it a vast number of specimens. His knowledge 

 and deep researches in plant life won for him the recognition 

 and friendship of many of the most noted scientists. Being a 

 deep student of nature, and possessing a brilliant mind, he saw 

 the most beautiful things in life. His gentle, earnest, loyal na- 

 ture won for him many firm friends, and indeed he was loved 

 by everyone who knew him. His life was full of promise until

Notes on the Mimicry of Two Sesiids : Sesia Rutilans 



and Sesia Animosa. 



F. Grinned , dr. 



In the early part of July, 1908, in Strawberry Valley, 

 San Jacinto .Mountains, (iOOO feet altitude, 1 collected specimens 

 of the above-named clear-winged moths. They were observed 

 in a rank meadow composed mainly of a rosaceus plant, the 

 flowers of which proved to be very attractive to most all in- 

 sects, especially the commoner forms of the region. From 

 about 10 a. m. till J p. m. this place was literally swarming 

 with insects of all descriptions, and a stroke with the net at 

 Chrysophanous Xanthoides, which was especially common and 

 conspicuous, would result in the capture of examples of other 

 insect orders. 



I took the first Sesia rutilans on July !», and up to the mid- 

 dle of this month over fifty of this species and only two 

 animosa.
