g-an in much the same way, these, too, having been blown about by 

 the wind. 



LacJuwstcnia iiiiplicita Horn; Hood, det. June 25. 



A common species, one of the first to emerge in early summer. 

 Found dead, with Lacon rcctangularis, in sandy lane leading to the 

 Devil's Hole. 



Polyphylla lianuinnuii Lee. August 12, 15, 17. 



Hart found one specimen lying dead on bare blowsand in the 

 marginal sand ridge just north of Havana, August 17, 1903. Mr. 

 J. L). Hood took six specimens at the Devil's Hole, August 12, 1907. 

 They were taken at dusk, flying rapidly about four feet above ground. 

 Three days later. Hood took seventeen males flying in the same 

 manner, and one female was found at rest. These are the only 

 records for Illinois. The species is of far-western distribution, and 

 is probably a typical member of the bunch-grass association of the 

 Great Plains. 



Anomala binotata Gyll. April i. 



A member of the subfamily Plcurosticti, which are leaf-feeders. 

 Common from late spring to early summer. Not distinctive of 

 sandy regions, and more or less an insect of cultivated fields. Re- 

 mains of a dead specimen, taken under a log at the border of a field. 



Anomala lucicola Fab. June 24, July 23. 



A common species of early summer. Occurs most commonly on 

 the leaves of wald grape and Virginia creeper. Taken on flowers 

 along roadside, with Strigoderma arboricola (probably breeding at 

 that time) ; also on the leaves of a bog plant at Matanzas Lake. 



Strigodenna arboricola Fab. June 15, 24, July 3, 6, 11. 



Common on flowers. Notes taken June 24: "The first Strigo- 

 denna w^as noticed a few days ago floating down the river. They 

 are now excessively abundant on cactus, wild rose, red clover, timo- 

 thy, elderberry, dewberry, dog fennel. Verbena stricta, wild parsnip, 

 Monarda punctata, Plantago, Sapouaria, Tcphrosia, Brigeron. They 

 are most abundant on prairie plants, being (luite common in the 

 bunch-grass association and along roadsides, very few being found 

 in the forest." July 3 : ''Strigoderma is still fairly abundant on 

 different flowers." On July 6 a robber-fly, Proct acanthus brei'i- 

 pennis, was caught with a Strigoderma in its grasp, which it was 

 in the act of eating. 

 Cotalpa lanigera Linn. June 28, July 2?^, April 4.
