The genus Sarcophaga is the most attractive to 
study among the genera ot the Superior Muscoid 
Flies not only on account of the morphology of the 
genitalia, but also on account of the great geogra¬ 
phical range of its members and the role that these 
play in human affairs. The geographical range is 
mainly due to the food 1 of the larva which is putrid 
flesh or decomposing human food and they are liable 
to be carried accordingly in these to different regions 
of the world. 
Eaunistic data on Sarcophaga species are only 
valuable, if such species ha^e been accurately de¬ 
termined by aid of the forms of their male genitalia, 
as pointed out by Böttcher p. 544 (i). The study for 
this reason can only be based on such papers as have 
been published by Böttcher, Kramer, Villeneuve for 
the palaeartic, and Aldrich and B. B. Parker for the 
nearctic region and a small number of species from 
other regions. Descriptions of authors that neglected 
l lie study of the male genitalia can not be used for 
such purposes except where type material has 
been studied. This is the reason why thé student of
