one is undivided. The inner row of spots on the secondaries 

 are also entirely yellow in P. Asterias, smaller and very differ- 

 ent in form from those on P. brevicanda. The second row of 

 spots is also smaller in P. Asterias, and the red spot at the 

 anal angle paler, with a smaller black dot in it, and a wider 

 crescent of bluish atoms above. The length of the tail, which 

 is one of the most striking points of difference, has already 

 been noticed." 



We have compared some interesting varieties of P. Asterias 

 in the Museum of the Boston Society of Natural History, col- 

 lected about Boston by Mr. Shurtleff, which approach (in the 

 reddish hue of the spots, usually yellow, especially on the under 

 side, and the shortness of the tail) the Newfoundland speci- 

 men kindly sent us by Mr. Saunders, and strongly suggest the 

 inference, with which Messrs. Scudder and Sanborn agree, that 

 P. brevicauda is a very remarkable 

 local variety of P. Asterias. 



The yellow Papilio Turnus Linn, flies 

 in June and July through woods and 

 about lilacs. Its larva feeds on the 

 apple and wild thorn ; it is green with 

 two e3 T e-like spots on the thorax, and 

 pupates in the middle of August. The 

 black dimorphic ? form, P. Glaucus, 

 is found in the Southern States. P. 

 I humus Boisd. (Fig. 180) originally Fi s- 18 - 



fuu iid in Mexico, has been found in Kansas, near the Rocky 

 Mountains, by Mr. James Ridings. He states that it strikingly 

 resembles P. Turnus, but has longer antennae, -with longer, more 

 curved fore-wings, besides differing in other characters. It ex- 

 pands nearly five inches. P. Troilus Linn, appears more com- 

 monly southward. The larva feeds on the sassafras and lilac 

 trees, and was found by Mr. Saunders feeding, rolled up on 

 a leaf, on the spice bush, August 3d. "Its length was about 

 one and three-fourths inches, the body being thickest from the 

 third to the fifth segments. The head is rather small, flat in 

 front, slightly bilobed, dull flesh color, with a faint tinge of 

 brown. The body is bright pea-green, with a yellow stripe 

 across the anterior part of the second segment ; edged behind 

 with dull black. On the fourth segment are two prominent
