found in California outside of the more desert regions of the 

 ^Southeast. The specimen mentioned by Fall, from Texas, 

 having an intermediate type of vestiture, is either a variety of 

 the Arizona species, or a species distinct from either this or 

 guttifera. It cannot be a connecting form, seeing that it is not 

 from intermediate territory but from a region at the extreme 

 end of the distribution of one of the species. 



Type and paratype, both females, collected at Florence, Ari- 

 zona, by C. R. Biederman, in the collection of the American 

 Entomological Society at the Academy of Natural Sciences of 

 Philadelphia. Nine other specimens from the National Mu- 

 seum collection I have also critically examined. Two of these 

 were collected at Catalina Springs, Arizona, April 26 and May 

 5, by Hubbard and Schwarz, one on Jatropha multifida, the 

 other seven at Hot Springs, Arizona, in June, by Barber and 

 Schwarz. One of these was reared from "Palo verde." These 

 nine specimens all have the two anterior discal elytral spots 

 three intervals broad and have five instead of four lateral 

 spots, the additional spot being placed subapically. Four of 

 the Hot Springs specimens I have designated as paratypes, a 

 male and female which will remain in my own collection, and 

 a male and female which will be returned with the five others 

 to the U. S. National Museum. For the privilege of studying 

 the two Florence specimens I am indebted to Dr. Henry Skin- 

 ner and Mr. E. T. Cresson, Jr., and for the others to Dr. E. A. 

 Schwarz and Mr. H. S. Barber. 



Acmaeodera quadrivittata Horn. 



This species is not as constant in marking as Dr. George 

 Horn supposed. The specimens from Southern Arizona gen- 

 erally have but one yellow stripe, the lateral one disappearing 

 in certain cases or coalescing with the discal stripe in others. 

 In the latter case the stripes are of course broad and they also 

 often have one or two black spots. These specimens are also 

 generally larger and more robust than typical specimens.

A series of specimens of this species which were collected at 

 Mojave, California, and which were kindly given to me by the 

 collector, Mr. C. L. Fox, have furnished me with the proof
