comparison, however, with actual specimens of the latter (speci¬ 
mens in the Milwaukee Public Museum) convinced me of its 
distinctness. 
Viewed from above the main feature of G. cornutus is that 
the superior appendages have two angles, the inner process 
being elongated and meeting on a level with the tips of the outer 
processes. In G. whedoni the superior appendage appears cut 
short with a small inner tubercle left in place of the long process 
of the other. This is shown very well in the figures. 
Described from a $ collected at Iowa City, June 9, 1908, by 
Mr. Arthur D. Whedon. Holotype in the collection of Milwau¬ 
kee Public Museum. Measurements the same as for G. cornutus. 
The nearest relative of this species, as already stated, is 
Gomphus cornutus Tough. I take great pleasure in dedicating 
this species to its discoverer, Mr. Arthur D. Whedon. 
Mr. Whedon writes of it as follows: “The spring of 1908 
was extremely cold and rainy, interfering constantly with collect¬ 
ing. The dragon flies had no chance to transform as the sloughs 
and ponds were abnormally flooded and the streams were roily 
torrents. Especially was this true of the first week of June. On 
the 9th, however, the skies cleared, the sun came out and the 
insects again began to move. 
“About the middle of the forenoon on this date the writer 
took a little run out to the ponds along the R. C. I. & P. Railway, 
a mile or so west of Iowa City. So cold was it that scarcely any¬ 
thing was on the wing until after 10:30, when a few benumbed 
Libellulidce were put to flight by sweeping the vegetation and 
a Gomphus fraternus 9 was captured as she sunned herself on the 
short grass of the pasture adjoining the slough. 
“At 11 o’clock I crossed the railroad embankment to a small 
pond between steep hills covered with hazel brush and other 
shrubs. There was no wind here and the sun beat in warmly. 
Many male L. pulchella were patrolling the shores, dashing around 
my net or rustling their wings in encounters with P. lydia at the 
point of some little promontory. A few Ischnura and Bnallagma 
skimmed the marginal waters. 
“Suddenly a medium sized Gomphus shot across the pond and 
appeared to dart without diminution of speed into a tall shrub
