in the Middle and Southern Sierras and is there generally 

 found in company with C. monticola Fall, as is the other with 

 it in the more northern parts of the State. 



Type male and female from Donner Lake, Placer County, 

 California, July 5 and 6. 1916, in my own collection: para- 

 types deposited in United States National Museum, Academy 

 of Natural Sciences of Philadelphia, and California Academy 

 of Sciences. The species is named in honor of my good 

 friend, Mr. H. C. Fall. 



Chrysobothris laricis Van Dyke. 



In a small series of specimens of Chrysobothris received 

 from Mr. G. R. Pilate and collected by him in the Tuolumne 

 Meadows of the Yosemite National Park, July u, 1916, I 

 found five females and one male of the above-named species. 

 These specimens all differ slightly from the typical phase 

 found in Eastern Oregon, in being more cupreous and bril- 

 liantly metallic, by having the transverse punctate areas of 

 the elytra more definitely defined, the sutural elevation more 

 widely explanate near the apex, and the dilated portion of 

 the anterior tibia in the male less broad though of the same 

 type. These differences, however, are simply differences in 

 degree and show that the species, like all of its relatives, is 

 variable. In this more southern area it also most likely breeds 

 in the lodge-pole pine, the dominant tree in the region. The 

 western larch does not extend into California. 



Chrysobothris exesa Lee. 



Within the last few years 1 have seen several specimens of 

 the above-named beetle that were taken in California, one 

 taken in 1912, in Imperial County, by J. C. Bridwell and the 

 others taken at Palm Springs, Riverside County, in April, 

 1917. by G. R. Pilate. These latter were taken on mesquite, 

 Prosopis juliflora D. C., making the sixth species of the genus 

 that I know of that lives on this tree, the others being: C. 

 octocola Lee., C. dcbilis Lee., C. mall Horn, C. merkelii Horn, 

 and C. gennnata Lee. The last, however, has not been re- 

 corded from California.
