OF WASHINGTON. 117 
One female from Santa Barbara, Cal., in collection of Prof, C. V. Riley. 
Eurypelma Hentzii Girard=E. mordax Auss., one of the common " Ta- 
rantulas" of the Southwestern States, differs from this new species by the 
longer legs, the higher eye eminence, the broader mandibles, the spinnerets, 
of which the basal joint is here the longest, and by the spinous armature 
of the legs. 
Eurypelma Steindachnerii Auss., a species which occurs frequently in 
California can be readily recognized by the large velvety-brown spot on 
the otherwise light-colored abdomen. 
Eurypelma caltforntca Dol. Distinguished from our species by the 
smaller mandibles, the narrower sternum, and the blackish-brown color 
of the underside of the abdomen. 
Mr. Howard read a paper, of which he has submitted the fol- 
lowing abstract : 
A MISCONCEPTION REGARDING THE LECONTE EDITION OF SAY. The 
title-page of the two-volume LeConte edition of Say reads: "The com- 
plete writings of Thomas Savon the Entomology of North America," and 
from this wording of the title-page I have reason to believe that the im- 
pression is very general that in this edition LeConte included all of the 
entomological papers written by the father of North American descriptive 
entomology. Such, at least, was my own impression. 
In 1884 I found in the Journal of the Academy of Sciences, .of Philadel- 
phia, for August, 1817, vol. i, page 63, an interesting note by Say, which 
I have republished with comments in Psyche, vol. iv, page 206, August and 
September, 1884. I have recently found two other articles in the Memoirs 
of the Philadelphia Society for promoting Agriculture, vol. iv, 1818, the 
one a letter dated September 28, 1817, published upon page 224, and the 
other a letter dated October 30, 1817, published upon page 236. The find- 
ing of these three articles lead me to the conclusion that the editor intended 
simply to bring together descriptive papers of' Say, and this conclusion is 
verified by a paragraph in Dr. LeConte 7 s preface. The title page is there- 
fore very misleading, and the cause of a general misconception as to the 
scope of the work on the part of entomologists. After the preparation of 
this note I discovered that the two letters of Say referred to have been men- 
tioned by Dr. Hagen in Psyche for March, 1884. The U. S. Department 
of Agriculture possesses a copy of the now rather rare Memoirs of the Phila- 
delphia Society abovs mentioned.
