abundant, and rush to the barren phiees only upon the approach of the 

 observer. 



One C. ancocisconensis was found with these re-panda. No other speci- 

 mens were found throughout the county. 



Upon the bluffs and in level upland fields several C. pimclulata were 

 observed. At points where the banks were sloping the two species were fre- 

 quently found feeding together, but when flushed each took flight in the di- 

 rection of his o'\\'n habitat, namely, the repanda to the damp lowlands and 

 the pundulata to the upland fields. 



Kosciusko County. June 19, 1916, was de^'oted to a close survey of the 

 B. and O. railroad cut one mile east of ]Milford Junction. From the base 

 of the cut flowed a number of small springs, which had washed sediment 

 from the bank and thus formed a sand clay marsh between the bank and the 

 railroad. At a number of points there was sufficient water to form small 

 pools along the track. This gave, Avithin two hundred feet, the following 

 varied environment, wheat and pasture lands, turf overhanging a ten feet 

 perpendicular day bank contiguous with an eroded sand clay bank, level 

 sand clay beds l)ordering upon the marsh, Avater pools and lastly the rail- 

 road track. 



Three species of Cicindelidic were found in al)undan(-e under these con- 

 ditions, and when disturbed each responded to the natural environmental 

 impulse of the species. C. repanda would take flight toward the railroad track 

 and light on the ties over the water, or on the barren spots at the edge of 

 the marsh. C. sexguUala would flj^ in the opposite direction to the top of the 

 cut, or passing on into the fields beyond, while C. ancocisconensis would 

 usually alight on t he sloping banks. 



The CicindelidtP are comparatively scarce in central Kosciusko county, 

 due no doubt, to the unfavorable physcial conditions of the land. The bor- 

 ders of the lakes and waterAvays are either marshy fields or rolling hillsides 

 covered with dense vegetation, presenting unfavorable breeding places. 



With the exception of C. punctulata, the specimens from this county were 

 collected here and there and not found in large colonies. This was also the 

 case in many other counties. A few scattering specimens of sexguUata. 

 repanda and ancocisconensis were found in June and earlj' July, after which 

 they disappeared. The ncAv brood of the last two species appeared in late 

 July, aliout the time of the coming of the single brooded punctulata. 



C. punctulata became abundant in dry pathways and open fields by the 

 first of August. They were especially numerous in sandy potato patches, 

 where they were attracted by the smaller of the potato beetle larvae. They 

 were ofttimes seen on the leaves of the potato plant enjoying their tender 

 food. This is the onlj' species that I have observed securing its food from, 

 or even perching upon, vegetation of any kind. 



August 19, 1916, was spent in studying the life habits of a formerly se- 

 lected colony of C. punctulata. These inhabited a semi-barren spot in an
