46 



mains of dead beetles taken under logs July 28, on the river dune 

 south of Havana; April 4, at the border of a bunch-grass field, on 

 a dune east of Havana. 



Ligyrus gibbosus De G. July 23, April 4. 



A common and widely distributed species often attracted to elec- 

 tric lights. Taken in stomach of a toad with Serica sericea and 

 other insects. The toad was taken in the mixed forest of the river 

 dune, indicating the same habitat for the beetle. A fresh-looking 

 specimen, perhaps recently emerged, was taken under a log in the 

 bunch-grass. 



Euphoria sepnlchralis Fab. August 14, 16, 18, 30. 



Common in southern Illinois; found in prairie flowers, especially 

 Solidago. Hart took specimens at the Devil's Hole, Alatanzas Lake, 

 and other places. 



Euphoria inda Linn. April 9. 



Worn specimens taken at the Devil's Hole, flying about. In 

 April, 1910, these beetles were flying about in the same way in the 

 sand dunes of Lake Michigan, north of Waukegan, Illinois. The 

 larvae feed upon manure or rich soil containing a large amount of 

 humus. 



Trichius pigcr Fab. July 11. 



Found in early summer in flowers. One specimen, taken in a 

 flower of wild rose, along sandy roadside south of the Devil's Neck. 

 A fairly common species of general distribution. 



Batyle suturalis Say. July 25. 



The Cerambycidae are generally adapted to forest life. They are 

 timber-boring insects. A number of fomis are somewhat aberrant, 

 and this group is represented in prairie associations. This species 

 is occasionally found in flowers of Ceanothns, Cornus, and other 

 plants. Taken on Chrysopsis villosa, near border of black-oak for- 

 est, three miles east of Havana. A common and generally distrib- 

 uted species, but never very abundant. 



Strangalia Intciconiis Fab, July 5. 



Occasionally found on flowers; early summer. Two specimens, 

 taken on Chrysopsis Tillosa along a railroad track. 



Piectrodera scalator Fab. July 8, August 13. 



Associated with species of willow and poplar in sand regions. 

 Found at the lower end of Lake Michigan; at Grand Tower, Illi- 

 nois, in the Mississippi sand deposits; at Waukegan, Illinois; and 

 at the Devil's Neck, in Populus. The larvae bore in the trees.
