E. tetraspilus Loew. Milwaukee Co. and Washington Co. 2 males 
from Milwaukee have the yellow on the scutellum limited to the tips, 
while in 2 other males from the same locality the greater portion of 
the scutellum is yellow. 
Nemotelus. 
N. unicolor Loew. Milwaukee, Racine Co., Prescott and Maiden 
Rock in Pierce Co. 
EHYPHIDAE. 
Rhyphus. 
Only 4 species are known from North America. One of these, (R. 
scalaris Wiedemann) is of southern distribution (type locality: 
Georgia). R. alternatus and R. fenestralis inhabit the northeastern 
United States, and the latter has been taken as far north as Quebec. 
R. punctatus, the only species occurring in our region has been 
reported from Quebec, the White Mountains in New Hampshire and 
New Jersey in the east; Minnesota and Kansas in the west. It is also 
an inhabitant of Europe, and according to Schiner (Fauna austriaca, 
Diptera, vol. 2, p. 495) it is found in Austria mostly at high altitudes. 
R. punctatus Fabricius. This is to all appearances a species of 
rare occurrence in Wisconsin. There are 3 specimens in the collection 
of the Public Museum of Milwaukee: 2 from Milwaukee Co., and 1 
from Grant Co. These agree with Schiner’s description based on ma¬ 
terial collected in Austria, except that the brown spot opposite the spot 
in the stigma is not confined to the first posterior cell, but invades the 
second posterior cell on one side, and the sub-marginal cell on the 
other, thereby uniting with the stigmatal spot. But the latter is much 
darker than its neighbor, and therefore distinctly outlined. In a speci¬ 
men from Dane Co. (collected by Prof. Wm. S. Marshall) on the other 
hand, the spot in the first posterior cell is clearly separated from the 
stigmatal spot, and both are very light in color.
