63. Rusticus battoides Behr (429). 



So far as I am aware but one specimen of this butterfly has been 

 taken in this locality. It was taken by Mr. George Field at Jacumba 

 in July, 1906. Battoides and glaucon may be quite easily confused by 

 one not familiar with both, and I have seen at least one large series 

 of glaucon that had been called by the former name. I am convinced, 

 however, that the species most commonly found in this locality is 

 glaucon and not battoides. That battoides does occur is quite certain, 

 but I am inclined to the belief that it is confined to the more elevated 

 regions back from the coast. 



64. Rusticus melissa Edwards (431). 



Melissa is a very common "blue" in this locality if you know 

 where to look for it. Mission Valley is fine collecting ground for 

 it. At Morena Dam, in July, 1906, it was so thick in a little valley 

 near the dam that I took over a hundred specimens one evening after 

 sundown, picking them off the grass with my fingers, no net being 

 necessary. The specimens in Mission Valley are a little smaller than 

 those taken in the mountains. 



65. Rusticus acmon Doub. & Hewit (434)- 



At times acmon is very common here, though this year it has 

 been rather scarce. It frequents the sunny hillsides, and is not un- 

 common in Mission Valley where it likes to fly about a species of 

 Hosachia. It is quite variable in depth of color and also in size. 

 Some specimens are almost as large as melissa. The larger specimens 

 are usually considerably darker than the small forms. 



66. Cyaniris ladon (var.). 



One specimen taken in July, 1906, at Grapevine Canon. 



67. Everes amyntula Boisduval (441). 



Amyntula is quite common in the canons about the city, espe- 

 cially where the "rattle-weed" grows. I have also one specimen 

 and Mr. George Field has two of a butterfly that has all the appear- 

 ance of amyntula without the tail. These specimens were taken in a 

 canon just back of St. Joseph's Hospital and were supposed to be 

 amyntula when taken. 



68. Hemiargus isola Reakirt (444)- 



One somewhat damaged specimen taken at Jacumba, July, 1906.
