Three males were found: one was in material from WinchelTs 
Pond, near Kilbourn, Wisconsin; one in material collected by 
Dr. E. A. Birge in Audubon Park, New Orleans; and one was 
found by Dr. R. A. Muttkowski in material from the lakes at 
Madison, Wisconsin. 
Neumania fragilis nov. spec. 
Plate II, figures 7-9 
This is a small and delicate mite. The body is rounded, the 
anterior end narrowed as seen laterally. The braces from the 
first pair of epimera are broad and extend to the middle of the 
fourth pair. The fourth pair of plates are relatively narrow. 
The genital area is faintly outlined, and the plates are narrow 
in the female, with few acetabula. The legs are slender and 
bear feathered bristles; the latter are quite conspicuous on the 
fourth pair. The body length in the female is 0.90 mm. The 
male is unknown. 
Four individuals were examined: one came from a pond at Ep- 
worth Heights, near Ludington, Michigan; and the others were 
found in the lakes at Madison, Wisconsin, by Dr. R. A. Mutt¬ 
kowski. 
Neumania muttkowskii nov. spec. 
Plate II, figure 10. 
This new species is large and dark. The epimeral area is mod¬ 
erately large, the anterior group is separated from the posterior 
by a wide space, and the braces underlying the groups are nar¬ 
row. The genital area of the male is distinct, rounded, and small 
with the acetabula somewhat remote from each other; it is re¬ 
moved from the leg plates and from the posterior end of the 
body. The legs are stout, and the palpi are small and slender. 
Three males were found; the average body length is 1.00 mm. 
One female was found, but not in good condition for study. The 
species is named in honor of Dr. Richard A. Muttkowski who 
found the material in the lakes at Madison, Wisconsin, in May, 
1915.
