Of the Great Basin (small districts in Mono, Inyo, Modoc 

 and L,assen Counties in the south and north), Cicindcla 

 ciuctipcnnis, C. pscndosenilis, Elcodes nigrina, several Auiiiro-

Of the Southern California!! (northern and southern types 

 somewhat mixed), southern forms like Asida, Phheodcs, Zophc-

 Acmceodera and Cantharidse. 



He further stated ' ' these various faunas and subfaunas are 

 of course quite distinctive within certain limits, but along their 

 margins they intermix, constituting the so-called transitional 

 zones. Attention w r as called to the theory of a succession ot 

 migrations of southern types to account for southern species 

 being domiciled within the region of more northern forms, such 

 as the Coniontini, Blapstinus and several Eleodes. 



Mr. Beverly Letcher in a paper on the "Distribution of Cali- 

 fornian Day Fliers," said : Consideration has been given to 

 the distribution of Lepidoptera only, without reference to other 

 orders, and the subject approached as though nothing existed 

 in California but the butterfly. 



One hundred and fifty-eight day fliers out of 225 species 

 credited to the State are considered. Distribution closely fol- 

 lows the coast and Sierra Nevada Mountain ranges ; the inter- 

 vening valleys have no distinctive fauna ; there is, in addition, 

 the Southern California, including Santa Barbara, Ventura, 

 Riverside, L,os Angeles and San Diego Counties w 7 est of the 

 mountains, and the desert in the southeastern part of the 

 State, and the so-called Alaska Maritime and Great Basin 

 faunas, which are not considered for lack for data. 



Information with regard to desert fauna rests on one list pub- 

 lished in the ENT. NEWS. Of 23 species reported, 18 are pe- 

 culiar to the desert. Distribution of others as follows : 



Peculiar to northern coast . . . 22 species.
