Pliyllopliaga liorni Smith 



Horni was obtained by us only from central Illinois in the years 

 1908 and 1909, 64 specimens in the first year and 2 in the second, 

 from May 17 to June 21. Forty-six of our specimens were from food- 

 plants, 36 of these from blackberries, 4 from oaks, 2 from poplars, 1 

 from willow, 2 from cherry, and 1 from elm.

 Pliyllophaga praetermissa Horn 



Praetermissa is apparently a distinctly southern species, repre- 

 sented, it is true, in our materials by 55 specimens only, but all of 

 these coming in three different years from the southern part of the 

 state at dates ranging from May 14 to June 22. They were well dis- 

 tributed from Odin, Ashley, and Duquoin to Shawneetown on the 

 Ohio. Only 26 of our specimens were from food-plants, 13 of them 

 from oak, 9 from willow, and 4 from apple. 



Pliyllopliaga prunina Leconte 



Prunina is represented by small scattering collections made dur- 

 ing three years in all parts of the state and amounting to only 33 

 specimens. The fact that 3 were from oaks and 1 from hickory gives 

 us only a hint of the probable character of its food. 



Prunina was surprisingly abundant among May-beetles collected 

 near Chicago for Mr. J. J. Davis in 1914, where 2142 of this species 

 were taken in a total of 16,550. I am informed by Mr. Davis that 

 this is characteristically a species of sandy situations, a fact which 

 will account for its general scarcity in Illinois. 



Pliyllopliaga longitarsa Say 



Longitarsa, represented with us by 15 specimens, was taken only 

 at lights in Grand Tower, Jackson county, July 12, 1909. We have 

 thus no hint of the character of its food. 



Pliyllopliaga arkansana Schaeffer 



Arkansana was represented by a single collection of 11 specimens 

 taken from lights at Ashley, Washington county, May 4, 1908. 



Pliyllopliaga villifrons Leconte 



Our 9 specimens of villifrons came from northern and central 

 Illinois, 8 from lights at Algonquin, June 14 to July 8, and 1 from 

 an oak at Galesburg, June 4.
