Introduction 
In 1922 Dr. A. V. Martynov read a paper before the 
Entomological Society of Russia on the interpretation of 
the veins and trachese in the wings of the Odonata and 
Agnatha (Plectoptera) . His manuscript was turned over 
for publication in 1923 and after some delay was finally 
published in Russian the following year (Rev. Russe Ent., 
18(4) :145-174). In connection with my investigations on 
fossil insects, I found it necessary to consult his paper, 
and from the very short French summary at the end of 
the article, I felt sure that the text contained important 
data and discussions which should not be overlooked. I 
therefore employed Miss Olga Jahr, of the Slavic Depart- 
ment of the Harvard Library, to assist me with the trans- 
lation of the Russian. Naturally enough, Miss Jahr was 
unfamiliar with the biological terms, but by working to- 
gether we obtained a complete English translation without 
much difficulty. As the translation progressed it became 
more and more evident that the text was fully as important

the Russian Entomological Society, November, 1922; the manuscript 
was handed to the press in May, 1923.
