A few solitary specimens of C. -punctulata were found on the upland fields 

 and roadsides. 



Dubois County. May 1, 1916, collections were made in the vicinity of 

 Huntingburg. The race track at the county fair grounds proved to be a choice 

 feeding and breeding spot for C. re panda. The track had been covered with 

 straw to prevent washing. On one side was a steep clay bank, while on the 

 other ran a small stream. The latter furnished a good feeding place for the 

 beetles in dry weather. At the time of collecting, however, the ground was 

 extremely wet and large numbers were to be seen sunning on the banks. 

 Others were feeding on the small insects and worms found in the straw. 



Observations were made tln-ough the lowland districts near to^vn but no 

 beetles were seen. Then the hiU land was studied, with interesting results. 

 After collecting a few vulgaris and one ancocisconensis in a red claj' wheat- 

 field, a point was reached where the public road had been cut through a 

 ridge, leaving the banks on either side about fifteen feet high. A strong 

 wind directed hundred of ('. vuhjaris into this retreat, where they would settle 

 on the warm banks. They were so abundant that they could be captured 

 with perfect ease by swinging the net tlu'ough the air. 



Perry County and neighboring parts of Kentucky. Observations were 

 made in the Adcinity of Rome, Tobinsport, Cannelton, Tell Cit3^ and Troy, 

 Indiana, and Cloverport, and Hawesville, Kentucky. A rather critical 

 study of the sand bars and banks on either side of the Ohio river was made 

 at intervals from Rome, Indiana, to Hawesville, Kentucky, with a view of 

 ascertaining whether or not this stream affected the distribution of Indiana 

 and Kentuckj' Cieindelidae. In tliis comparative study only one species. 

 C. repanda, was found. This, however, was verj^ abundant. In the two 

 different surveys made of this region during the months of May and June, 

 19 IG, no indications were found of the river's acting as a barrier. The same 

 species and apparenth' the same brood that Avas found on the Indiana side, 

 was found at adjacent points in Kentucky. Indications were that these 

 beetles sometimes fly across the river, as manj' were watched for at least 

 half the distance, when they disappeared from sight. 



The ne.xt obsenations were made over the red (-lay hilh^ region of this 

 county from Troy to Bristow, a distance of about thirteen miles. C. purpurea 

 and C. sexgultata and C. vulgaris were found abundantly in damp ravines 

 but rarely in upland regions. 



Spencer County. In the latter part of May, 1916, two different collections 

 were made in the locality of Lincoln City. It so happened that each visit 

 was made during extremely wet weather and thus little data were obtained. 

 A single specimen of C. sexgultata was found on a concrete walk, also a number 

 of C. vulgaris were collected along the muddy roadways and on barren spots 

 in clay pasture fields. These were ver>- sluggish and easily captured, indi- 

 cating that they had been forced from their hiding places either by the ex 

 cessive rain or by hunger.
