ZOOLOGY INSECTS. 



1873 obtained in Arizona by Dr. C. Gr. Newberry. The specimens described 

 by Walker and Stal are from Mexico. 



Before leaving this family, I will give a list of the species whose posi- 

 tion is affected by Dr. Stal's work so far as I ana able to do so at present ; 

 but before this can be completed it will be necessary to examine all the 

 species, but, most of my types being now at the Agricultural Department 

 in Washington, I can only give such as are mentioned by Stal and those 

 of which I have specimens before me. I also add the names of the new 

 North American species described by Stal, and in this paper and also those 

 in other papers published since my Synopsis, so as to complete the list of 

 species.
