PAPILIO 11. 



brown ; the other tails are entirel\' Ijlack, rounded at end ; the lengths of the 

 three are about as 63 ; oO ; 22 ; fringes of primaries yellow, of secondaries same 

 in the emarginations, the I'est black. 



Under side yellow, the black markings repeated, paler ; the subraarginal yel- 

 low stripe broader, and now a continuous band ; the line of scales more definite ; 

 the interior of tlie second band yellowish-black through its length ; the spots 

 on secondaries much enlarged, all washed red-brown ; above each the ground is 

 dusted yellow, with increasing density towards the top, and the series ends in an 

 elongated narrow metallic blue spot, above which the clear black ground shows 

 in a. small lunation ; the yellow on disk next the marginal band in the median 

 and submedian interspaces washed red-brown. 



Body above black, a yellow stripe passing along thorax from head to insertion 

 of wings ; beneath, thorax yellow ; abdomen yellow, with a ventral black band 

 and lateral line; legs black ; palpi yellow; antennce and club black. (Figs. 1, 2.) 



Female. — Expands 4 to 4.5 inches. 



Like the male, the red-brown on upper side darker. (Figs. 3, 4.) 



Nothing is known of the early stages of this species, nor of the food plant, but 

 probably the larvae feed on plum, cherry, and, in general, the same plants as 

 Daunus. 



One or two examples of Pilumnus were brought fi-om New Mexico by the 

 \Yheeler Expedition of 1871, as Mr. Mead relates. But what the locality was is 

 forgotten. And the late Mr. H. K. Morri.son took one male in Arizona, in 1882, 

 on Graham Mountain, as is believed. I know of no other instance in which the 

 species has been taken within the United States. Its home is in Mexico and Cen- 

 tral America. Hearing that Professor Edward T. Owen of Madison, Wisconsin, 

 had seen PUumnus in Mexico and captured many examples, I wrote him for what 

 information he could give me, and his reply was as follows : " My experience with 

 Papilio PiLUMivus is limited to the region about Jalapa, in the state of Vera Cruz. 

 Some years ago, I took several, mainly at the summit of a sharp liill of two or 

 three hundred feet elevation above the surrounding country. This sunnnit, dur- 

 ing the months of February and March, was a trysting place for quite a number 

 of species of butterflies. They seemed possessed with an instinct for mounting, 

 and on reaching this hill would rise along its slope to the summit. Once there, 

 they circled about till the end of the entomological day. Most species showed
