species is a subject of great interest, and one about which but very httle 

 is known at present. 



I have in my possession a male Papilio turmis which has only two 

 wings. An examination shows that the hind wings are undeveloped ; on 

 one side the membrane is pushed out and rounded at the end about as large 

 as the head of a pin, and on the other side the membrane is no longer, but 

 is broader and somewhat flattened, showing plainly that the wings have 

 not been broken off, but have never developed. This specimen was cap- 

 tured on the wing, while hovering over lilac blossoms, and appeared to fly 

 as well as perfect specimens. 



In the summer of 1884, I captured a male Papilio tur?ms which differs 

 very much from any I have ever seen or read of The outer half of the 

 upper side of all the wings is black, except the row of yellow spots on the 

 outer margin of the wings. These are round or nearly so, instead of 

 elongated, and there are only six on the fore wings. The inner half of 

 the fore wings is like the ordinary P. hirtms, except that the two black 

 streaks are united from the costa down about half their length. The 

 under side of the fore wings is like the upper side, but slightly dusted 

 with yellow. The under side of the hind wings has the blue extended 

 nearly as far in as the black upon the outside, and, together with its black 

 border, is very strongly curved or toothed towards the base. All the 

 yellow on the wings is darker than on the common form, and the insect 

 when flying looked more like a male P. astej-ias, except in size, than like 

 a P. turnus. 



It was captured in June on the bog where Chionobas jutta, Chryso- 

 p/ianus epixanthe, and several other rare lepidoptera are found.

During the past two years, but more especially this season, we have 

 been very much troubled and annoyed by the attacks of the Buffalo Tree- 

 hopper (C. btcbalus Say) on the young trees in the orchard. Most of the 

 trees have been seriously injured by having the bark cut up by the 

 ovipositors oi these insects, when depositing their eggs. These incisions
