tained from corn plants in a field which had lately been plowed 

 from g-rass. As these beetles had often been said to suck the sap 

 of the stalks they pierce, one of these specimens was dissected to 

 determine the nature of its food, and this was found to consist of 

 bits of the characteristic epidermis of g^rass-like plants and of par- 

 allel-veined veg-etation containing- spiral vessels— evidence,of course, 

 that its injuries to corn are done by biting- and swallowing- the sub- 

 stance of the plant and not by sucking- the sap. This specimen 

 was a female, well filled with fully matured eg-g-s. 



On the 24th of May, 1S*)7, at Union Grove, Whiteside county, 

 it was found very abundant on corn below the surface ; and at Ur- 

 bana. May 24, 1889, a specimen was taken from a stem of g-rass 

 which it had punctured throug-h the sheath of the second leaf from 

 the g-round. May 25, l')01, at Knoxville, in Knox county, several 

 specimens were taken from corn g-rowiag- in sod. The beetle was 

 doing- a rather serious injury throug-hout the field. On the 2Gth 

 of Ma3% 1885, one was taken with its beak thrust into a stalk of 

 young- corn about three inches hig-h, the puncture being- made an 

 inch above the g-round. The beetle was so eng-rossed with its feed- 

 ing- that it remained attached after the corn was pulled up and un- 

 til it was forcibly picked away. On the 27th of May, 1887, a speci- 

 men was found under a board on the g-rass, and on the same day of 

 the month in I'XJl another was taken from young- corn at Oneida, 

 in Knox county. On the 28th of May, 1901, specimens were broug-ht 

 in as injuring- young- corn at Buda, Bureau county, and also on the 

 31st of that month in 1887 at Rankin, in Vermilion county. 



June 7, 1884, a beetle was taken near Du Quoin with its snout 

 inserted in a stalk of wheat close to the g-round. June, 8, 14, and 

 16, 1882, it occurred in miscellaneous collections in McLean county; 

 and on the 28th of June, 1900, it was seen at Grig-g-sville, Illinois, 

 feeding- on a corn plant eig-hteen inches hig-h. It was at the sur- 

 face of the g-round with its beak thrust far into the stalk. At the 

 same place on the next day it was taken from timothy, many of 

 the plants at this time being- infested by the larva- of this species. 

 July 1 to 10, 1883, it was collected at Normal, Illinois, and on the 

 19th and 21st of July, 1891, it was obtained at Urbana. On the 

 30th of July, 1900, it appeared in a breeding--cag-e, reared from 

 larva' which had been taken in timothy bulbs at VTrig-g-sville June 

 26, The transformations of this lot of larva; were not yet com- 

 plete July 30, the earth containing on this date eig-ht beetles, one 

 pupa, and four larva all alive. In Aug-ust, 1892, it appeared in a 

 breeding--cag-e of Professor Webster, in Ohio, bred from larvte of 

 that year. September 20, 1893, a specimen was found on the
