54. CiRROCHROA TYCHE, FeldeV. 



C5^ Felder, Wieuer, Entom. Monatschr. v, p. 301, n. 13, (1861.) 



Female. Upper surface ochreous brown ; a broad pale belt cros-^es the 

 outer half of the forewings, bordered interiorly by a gradually diuiinisliiu,:^ 

 waved dark brown bar, broadest below the subcostal vein, and becoming obso- 

 lete towards the inner margin ; the outer margin is dark brown, interior to 

 which are two angulated transverse lines, the outer being brownish black and 

 complete, the inner brownish ochreous, and obsolete in its lower portion ; 

 three indistinct brownish spots arise from the inner margin in the pale belt, 

 decreasing in size upward. 



On the secondaries the transverse belt is suffused with the ochreous ground 

 color, and contains six rounde<l or oval black spots — there being none in the 

 discoidal interspace ; the anterior narrow black line, and the posterior 

 lunulate or angulated lines, — three of these on the hind wings, — are all com- 

 plete, extending from the costal to the abdominal margin, an 1 anal angle. 



Underneath pale ochreous, the markings of the upper surface repeated in 

 pale shades; the outer half of the wing glossed with lilacine ; a continuous 

 lilaceous band underneath the mesial brown line. Expanse 2'75 inches. 



Antennae black, bright ferruginous underneath, and upon the club. 



Bab. — Mindoro. (Or. Chan. Semper.) (Coll. Tryon Reakirt.) 



I am indebted for this beautiful species, along with many other rarities, 

 to Mr. Georg Semper, brother of the celebrated collector. 



55. Papilio Burtoni, nov. sp. 



Size and shape of Pap. Leacaspis, Godt. 



Male. Upper surface pale greenish yellow; a very broad, dark brown 

 terminal band along the outer margin of both wings ; along tlie interior edge 

 of which band, on the forewings, is a darker brown stripe, extending from tlie 

 cell to the inner margin ; two wide dark brown belts traverse the fore wings, 

 both merging into the terminal border — one resting over the end of the cell, 

 cuts otf a small lunulate piece of the ground color, the other is a mesial 

 band, running from the middle of tlie costa towards the inner angle. 



Upon the border of the hind wings are several pair of imperfect lunes, 

 composed of lustrous bluish gray atoms ; above the anal angle a yellow 

 lune, and above this a red lune, sometimes two of these ; the brown border 

 is continued some distance along the abdominal margin. The long slender 

 tail teiminates with a large yellowish white patch. 



Underneath mainly as above ; the outer border of both wings is irrorated 

 with lilacine atoms, assuming the form of luuulae upon the lower portion 

 of the liind wings. Expanse 4 inches. 



Head, throat and abdomen, dark brown. 



Antennse black, with briglit orange brown clubs. 



Hah. — Insagasuga, New Granada. (Coll. Tryon Reakirt.) 



This magnificent species was one of a large collection formed by Hon. A. A. 

 Burton, near Bogota, and has most appropriately been dedicated to him. 



56. Dircesna Bairdii, nov. sp. 



Allied to Dir. Jemima, Hiibn. Wiftgs translucent, ochrey-yellowish, with 

 darker semi-opaque spots and border. 



Male. The fore wings are narrower and more acute than in the related 

 species ; the disposition of the ijellucid spots upon these is similar to Jemima ; 

 tlieir hind margin, however, is black instead of orange-orcheous ; the median 

 vein is orange to the end of the cell ; all the others black. 



Hind wings ; the black terminal border does not extend so far upon the 

 ablominal margin, upon which there is an orange brown patch, and is more 

 diffused inwardly ; the basal half of the wing is ochreous, as are also the veins 

 contained therein ; those upon the outer half, which is covered with the black 

 shade, are black. 



Underneath as above, with the addition of three apical silvery white spots
