FIELD NOTES ON TIGER BEETLES OF INDIANA. 453 



old pasture field, near Winona Lake. In addition to collecting food, the fe- 

 males were depositing eggs, while the males busied themselves in finding 

 receptive mates, or in attacking their opponents. The ground was so 

 hard and dr3% that the females were unable to penetrate it with the ovipositor, 

 and thus since they could not construct the usual ceU, they were compelled 

 to deposit their eggs in small cracks and other unfavorable places. All this 

 time they were continuaUy annoyed by the males attempting copulation. In 

 one instance a male forced a female to submission by clasping her between the 

 pro-and mesothorax with his powerful mandibles. After copulating about 

 five minutes, he remained in position over thirty minutes without seeming to 

 disturb the female in her feeding and egg laying habits. 



The food of this colony consisted of small ants and worms which were 

 collected under the vegetation. The feeding habits here were comparatively 

 the same as those noted with the repanda near Chile. 



Elkhart County. The afternoon of June the 9th was spent east and south- 

 east of Elkhart. The only Cicindelidse found was a large colony of repanda 

 in a gravel pit, southeast of town. The environmental conditions were es- 

 pecially advantageous to both larvae and adults. The high banks were 

 covered with sandy loam and turf favorable for larval gi'owth and adult 

 hibernation. The banks also gave protection from the cold while the various 

 insects attracted to the water at the bottom of the pit, furnished an abund- 

 ance of food. 



On account of the small feeding, area in comparison to the number of 

 Cicindelidse, close observation of the beetles while feeding was possible. Ants, 

 small beetles, flies and worms seemed preferable. One repanda continued 

 to cling to a large green worm until after he was caught in the net and trans- 

 ferred to a collecting bottle. 



Observations were made near Goshen, at the mouth of Rock Run Creek, 

 but since repanda was the only species found, no new data were obtained. 



St. Joseph County. On June 10, 1916, a careful survey was made along 

 the St. Joseph River between Spring Brook Park and South Bend, and also 

 through the uplands on the opposite side of the river from the city. Here 

 again only repanda were collected. On account of the dense vegetation 

 along the river banks, the beetles were confined in small colonies to the sandy 

 deltas of the small inlets. At these points, however, they were very abundant 

 and easily captured. 



Laporle County. Collections were made June 11, 1916, in late afternoon 

 around Pine Lake and among nearby hills, However, only a few specimens 

 of repanda were secured from the sandy lake shores. 



SUMMARY 



One or more Cicindelidse collecting trips were made in the twenty-one 

 counties indicated on the map, and specimens were received from a number 

 of other points.
