THE CANADIAN ENTOMOLOGIST. 107 



Eros coccinatus Say is found in April in the Cotton wood under logs 

 in the woods. 



Spkenophorus rj-pwictatus H., common on Rag-weed (Ambrosia 

 bidentata) in August. Common. 



I have taken Eburia quadrigeminata Say in the act of coming out of 

 Hickory trees in July ; they fly in the dusk of evening, and are quite 

 common. 



Dinoderus punctatus is found early in the spring on fences and build- 

 ings near the wood-pile, and I have taken them in great numbers in the 

 stumps of trees that had been grubbed out ; sometimes the small roots 

 would be almost entirely reduced to powder. 



Bostrichus bicornis Web. is found under the dead bark of White Oak 

 posts in August. I think the larva bores in the wood. 



Pledrodera scalator Fab. is found on small swamp Willows in August. 



Toxotas cylindricollis Say is found on wild flowers in July; not common. 



Epicauta convolvuli Mels. is found on May-weed (Maruta cotula) in 

 August, but not common. 



NATURAL HISTORY SOCIETY OF ILLINOIS. 



The Illinois State Natural History Society met at the Opera House, in 

 Bloomington, Tuesday evening, Feb'y 24th. After an address of welcome 

 from the citizens of Bloomington, and an address by Prof. A. H. Worthen, 

 of Springfield, 111., the retiring President, the original officers were re- 

 elected. Various papers and lectures were read before the Society, which 

 adjourned on Thursday; the 26th, having provided for a summer meeting 

 on the grounds of the Lake George Sportsmen's Association, near Chicago, 

 in July. This Society was organized at the Palmer House, in Chicago, in 

 January, 1879, and the Bloomington was its third semi-annual meeting, 

 but it still lacks somewhat in effectiveness for want of the full support that 

 should be accorded by the naturalists of Illinois, its aim being to embrace 

 in its membership every person in the State of Illinois interested in natural 

 science. The officers elected at Bloomington were : A. H. Worthen, 

 Springfield, President ; T. J. Burrell, Champaign, Vice-President ; S. A. 

 Forbes, Normal, Secretary, and H. N. Hibbard, Chicago, Treasurer.
