DIAPTOMUS SALTILUNUS Brewer, 1898 



Brewer described D. saltillinus from collections made in the vicin- 

 ity of Lincoln, Nebr. It was found by Pearse, 1905, in other locations

 it in the neighborhood of Fort Worth, Tex. Its distribution is 

 shown in Figure 7.

 common to all the Eastern States. Its distribution is shown in 

 Figure 8.
