18 During the summer of 1901 Boyeria vinosa was not rare in the low woods 

 about the Biological Station at Winona Lake. Students collected a large number 

 of nymphs of all sizes at Turkey Lake, July 19, 1901. 



19. A single exuvia ol Basiaeschna janala v/as found along the Tippecanoe 

 River near Warsaw, June 23, 1901, identified by Professor Needham. 



20. On August 24 and 25, 1901, Mr. Kennedy and myself collected several 

 males of Aeschna clepsydra at Shriner Lake, Whitley County. This makes the 

 Shriner-Round Lake list number 47 species. As observed on these two days, 

 clepsydra, as his brighter color pattern would indicate, is a more dashing fellow 

 than his common congener constricta. 



21. Macromia illinoiensis Walsh, Wabash River, Bluffton, June 20, 1901; 

 Tippecanoe River, near Warsaw, June 23, 1901; old canal feeder and St. Joseph 

 River, near Ft. Wayne, July 19 and August 11, 1901. Macromia taeniolala Ram- 

 bur. Old canal feeder and St. Joseph<River, near Ft. Wayne, July 19 and 

 August 11, 1901; associated with itlinoiensis, taeniolata being the most numerous. 

 This large dragonfly, floating idly or cutting through the air without apparent 

 effort, always flashing the sunlight like darts from glimmering wings and metallic 

 body, can not fail to draw the interest and admiration of any idle observer who 

 may wander along its haunts. Its alertness usually brings dismay to the crillector 

 who has waited patiently in waist-deep mud and water for its coming, and whose 

 deep and fervent reproaches follow the beautiful form as it sails away, first tree- 

 top high, then skimming the water with its strong front wings, in pure derision of 

 the impotent wretch who plotted so clumsily against its life. 



22. During the whole of July, 1901, and possibly later, Epicordulia princeps 

 was on the wing along the reed-grown shores of Winona Lake. This species spends 

 more hours per day on the wing than any other species in Indiana. In the gray 

 twilight, before sunrise, while the black bass were noisily gathering their break- 

 fasts in the shallow water, as we sat in the boat ca'ting to right and left with an 

 indigestible, hook-enshrouded minnow, princeps, misty and indistinct, floated 

 by. After sunset, when we went to the shore with the shotgun to snapshot at 

 bats, there he was again, out over the water, hurrying along in the gathering dusk 

 as though his day were not yet completed. 



23. On September 3, 1901, at an old gravel pit near Bluffton, I observed 

 Sympetrum vicinum ovipositing. The male held the female by the head as they 

 hovered a minute in front of a curtain of algae, formed by a mass of the plant 

 clinging to the edge of an old plank as the water had become lower in the pit. 

 This curtain was about nine inches high, the lower edge of it trailing in the 

 water. The dragonflies moved swiftly forward and the abdomen of the female
