this country. Mr. Dury also writes me that Miss Brown has 

 lately taken this species at Spring Grove Cemetery, Cincin- 

 nati, Ohio. In Mr. Knab's article it was mentioned as having 

 been taken by Prof. W. S. Blatchley in Indiana, but Prof. 

 Blatchley writes me that the specimens in question prove to 

 be Galerucella dorsata Say. 



The Illinois specimens mentioned by Mr. Knab were reared 

 from larvae found by Mr. Hart feeding on Phlox divaricata and 

 Dentaria laciniata near Urbana, May 12, 1888, the beetles 

 emerging June 16 and 18. In all our observations of the past 

 two years, however, they have been found only on Phlox 

 divaricata. 



In Planzenfeinde, p. 374, Kaltenbach gives the food plants, 

 in Europe, as Centaurea jacea, Cirsium palustre and Scabiosa 

 succisa. 



In the last few years Mr. Hart has collected the larvae at 

 Urbana, Homer, and Muncie, Illinois, and adults at White 

 Heath, Illinois. I have collected larvae at Urbana, Homer, and 

 Muncie, Illinois, and adults at Homer and Urbana — the only 

 places where I have looked for them, during the months in 

 which they occur as adults. All these places are within a 

 radius of thirty miles from Urbana, but the actual range of the 

 species is probably much more extensive. 



All specimens, both larval and adult, were collected at the 

 edge of the woods, or in the woods, where Phlox divaricata 

 grows — this being the only food plant upon which I have 

 found the species. All the beetles which I collected were found 

 around the phlox plants, and usually under leaves at the base 

 of a plant. 



The clusters of phlox plants upon which the larvae were 

 found in Urbana in 1905 occupied an area of not more than 

 ten or fifteen square feet, and in 1906 the larvae were not found 

 beyond this same limited area, although this was not due to any 

 scarcity of the food plant. Similarly, at Muncie, Illinois, 

 about twenty-three miles east of Urbana, the infested plants 

 were limited to an area of a few square yards, an area no larger 

 than that of the year before at the same place (May 14, 1906). 

 Mr. Hart found the larvae abundant at Homer, Illinois, a short
