The orthopterous and dermapterous insects taken on the 
above expedition, sent out by the University of Iowa, were mostly 
collected by Prof. Dayton Stoner, who submitted them to the 
writer for determination and report. At first glance the col- 
lection did not appear promising, but upon more thorough ex- 
amination it proved unexpectedly interesting, as will develop, 
the writer hopes, in the following report. Not only are there 
several apparently undescribed forms represented, but certain 
facts of geographical distribution, morphological variation, 
ete., have been brought out by the studies made. 
By previous arrangement the material here reported upon 
is divided between the collection of the U. S. National Museum 
and that of the University of Iowa, uniques, where desired, and 
types of new species going to the former collection. 
In the following pages the original references are quoted and 
also references to Kirby’s Synonymical Catalogue of Orthoptera, 
published by the British Museum, where one interested may find 
other pertinent references. Additional references are sometimes 
given and the more important synonyms are enterd, with the 
original reference to each. 
The entire collection as submitted to the writer consisted of 
334 specimens comprising 31 species, distributed in the various 
families as follows: 
Family No. of species No. of specimens 
Forficulide 2 16 
Blattide 8 50
