fornia, and the north-western great plains regions with a moderate 

 number of peculiar species. 



The flora of Guadalupe has yielded results entirely similar to that 

 indicated by the small series of Coleoptera before me, and an excellent 

 paper by Sereno Watson has been published, (Proc. Amer. Acad. Arts 

 and Sciences, vol. si.), giving the results of the study of one hundred 

 and ten phsenogamous plants, and as far as the distribution of insects 

 and plants is capable of comparison, there is a striking similarity in 

 the relationships of the species which are truly Californian and those 

 peculiar to the island itself. 



The following list of species shows also the various regions from 

 which they were previously known.

An inspection of the above list of twenty-three species shows that 

 the very large majority occur also iu the California fauna, two are 

 ■cosmopolitan, four are entirely new and probably peculiar to the fauna 

 of Guadalupe Island, one was previously known from Lower California 

 only, and two peculiar to the islands near the coast of California. 



Calosnma Palmeri, n. sp. — Black, shining. Body feebly winged. An- 

 tennas piceous, fourth joint slightly shorter than the fifth. Mandibles sparsely 

 punctured with coarse and fine punctures intermixed. Head nearly smooth, 

 with scarcely visible transverse wrinkles and very minute punctures. Thorax
