in Muncie, Delaware Co., July 25, 1916; a female was taken hawking just 
before sundown in my home yard in Bluffton on August 1, 1917, and a 
male was taken August 15 early in the morning clinging to vines in the 
same yard; April 12, 1919, a male was taken in the Union Savings and Trust 
Company, Bluffton; a number were taken in stores and houses in Bluffton 
in April, May and June, 1920. 
88. Macromia illinoiensis Walsh. Salamonie River, Huntington Co., 
August 5, 1917; on June 4, 1918, a female was caught on a window screen at 
the Wells County Bank building, Bluffton. 
84. Macromia pacifica Hagen. On August 26, 1917, two friends and 
myself hunted Macromias along the Wabash River above Bluftton. It was 
a cool windy day, altogether unfavorable for Macromias but we took an even 
dozen—eight of pacificu, two of wabashensis and two of illinoiensis. One 
or two identified on the wing as taeniolata were not captured. One pacifica 
was found crippled and unable to fly in the weeds along the river; one 
hind wing was broken at its base in the thorax and the body juices were 
exuding. Another of the same species was floating alive on the water with 
the front wing broken off near the base. It is probable both injuries were 
caused by birds. At Howe, Lagrange Co., on Sept. 3. 1916, I was asked to 
identify the birds which had nested in a blue bird box in the hotel yard 
during that year. A description of the birds by my informants left no 
doubt that they were great crested flycatchers. The birds were new to the 
parties observing them and the feeding of the young was especially inter- 
esting. They reported that they never saw the old birds carry in any other 
food than large dragonflies. An examination of the nest showed a quan- 
tity of bits of dragonfly wings and legs. I was able to identify a bit of 
wing of Libellula pulchella but the bulk of the material was parts of Macro- 
mias. There is no doubt that dozens of the-e insects had gone to supply 
this one nest. Martins are very numerous in boxes placed for them in 
Bluffton. The birds spend many hours over the river and the abandoned 
adjacent quarries near Bluffton. That they feed on large dragonflies is 
no question though I have been able to certainly identify only Libellula 
pulchella. But in many years’ collecting along the Wabash I have seen 
only one Macromia near Bluffton. On the other hand, Gomphus occurs 
within the city limits in apparently as large numbers as elsewhere. But the 
Gomphi have a relatively short sensonal range, they burst their exuviae by 
hundreds or thousands almost simultaneously, and their eggs are laid and 
their aerial life ended before their predaceous enemies could gather in 
numbers to attack them. The longer seasonal range of Macromias, by 
reason of which the brooding mother bird and later her offspring, from 
hatching to leaving the nest, could be fed on this one species of insect, 
obviously invites danger. The pair of great crested flycatchers at Howe 
doubtless became expert Macromia catchers by the time their offspring took 
wing. 
85. Macromia taenioiata Rambur. At a bayou two miles west of Merom, 
Sullivan Co., July 23, 1918, one male captured and one or two more seen. 
Later, on August 3. we found the species in numbers at the Tennessee River 
ferry between Jasper and Chattanooga, Tennessee.
