COLEOPTERA OF BAJA CALIFORNIA. 305 



American fauna and be considered as belonging to that 

 of Central America. 



Although politically a portion of the Republic of Mex- 

 ico, the editors of Biologia Centrali-Americana have not 

 considered the region as properly within their province by 

 reason of the strong claims made for it as a part of the 

 faunal region of our southwest. 



The following pages consist of two distinct parts — a 

 catalogue of all the species known to me as having been 

 collected in Baja Cahfornia, followed by descriptions of 

 new species or comments on new occurrences. 



The catalogue is a systematic one, following the order 

 of the families of our most recent lists. Following each 

 species is a list of localities, giving the general distribu- 

 tion as far as known to me, and in each case the special 

 localities as given by the collectors. A certain number 

 of species are from unknown localities; those of the 

 Xantus series are quoted as from " Cabo San Lucas." 

 In the case of a few in Mr. Ulke's cabinet, and not else- 

 where represented, they are quoted " Baja California 

 (Ulke)." The greater part of the latter are doubtless 

 from the Cape Region, but species are among them col- 

 lected south of San Diego. 



The descriptive part contains descriptions of new spe- 

 cies. The names appear in their proper places in the 

 list, but the descriptions have been separated, so that the 

 catalogue will not be broken up irregularly. 



By the kind permission of the Publication Committee 

 of the Academy, I have added descriptions of a number 

 of new species either from adjacent regions or bv reason 

 of their relationship to those included by right in the 

 paper. 



I must at this time acknowledge the assistance render- 

 ed by Mr. H. Ulke of Washington, in completing the 



2d Ser., Vol. IV. (20) August 3, 1894.
