Nemestrinidae (Diptera) of Iowa and Missouri. — 
A small collection recently sent by Mr. Jean L. Laffoon, at 
Iowa State College, contains a male of N eorhynchocephalus 
sackenii (Williston) collected at Sioux City, Woodbury Co., 
Iowa, June 10, 1949, by J. A. Slater and J. L. Laffoon. It 
was taken immediately above the mouth of the Sioux River, 
on top of the loess hills which border the Missouri River 
in western Iowa. Mr. Laffoon points out to me that this 
area contains some plants and animals ordinarily found 
only farther west. It is the first record for any of the 
Nemestrinidae in Iowa. Specimens of N. sackenii were 
also collected at Washington University Farm, 7 miles 
southwest of Clarksville, Pike Co., Missouri, by Mr. Robert 
A. Dietz, of the University of Tennessee. N. sackenii is 
now recorded from British Columbia and the states of 
Washington, Oregon, Montana, California, Idaho, Wyom- 
ing, Utah, Arizona, Colorado, New Mexico, Kansas, Okla- 
homa, Arkansas, Missouri, Iowa, Michigan, and Illinois. I 
have seen specimens from Huachuca Canyon, Cochise Co., 
Arizona, August 17, 1950 (R. L. Langston). It is remark- 
able that there are as yet no records from Mexico. — J.
