there Mr. Evans says: "It is quite common, and presents many curi- 

 ous examples of black and yellow blended and mixed in the same insect. 

 I took one in which the left wing and half body were yellow, and the 

 right, black. I saw another last season that seemed to be equally black 

 and yellow, the two colors being almost evenly distributed over the whole 

 insect. There are about half as many glaucm as turnw in the county." 

 In Indiana turnus is double brooded and winters in the chrysalis.

This is our largest and rarest Papilio. Its range, as given by Edwards, 

 is " Southern and Western States, but moving east and north " It is re- 

 ported as rare by most of the persons who have sent in lists. During the 

 six years which the writer has collected in the State he has seen but two 

 living specimens, one in Montgomery, the other in Wabash County. 

 The food plants of the larvse, Ptelea trifoliata, L., and. Xanthoxylum 

 Americanum, Mill (Hop tree and Prickly Ash), are not rare in Monroe 

 and Vigo Counties, yet the butterfly has not been seen in either, although 

 a constant outlook has been kept for it. Where found it is usually near 

 streams, and flies swiftly and high in air, thus rendering its capture 

 difficult.
