outer margins light brown, the costal margin with a triangular tooth 

 of brown beyond the cell, the outer margin more broadly bordered 

 above than below and often tinged next the edge with yellow; 

 hind wings fulvous yellow outwardly, the extreme margin brown, 

 pale gray at base with a median and more obscurely a prebasal 

 transverse white band broadest on the costal margin. Under sur- 

 face ochraceous yellow with the white markings of the upper 

 surface repeated, the prebasal band of the hind wings distinct 

 and brown-edged, the median band more or less broken into un- 

 equal brown-edged sometimes confluent roundish spots. Expanse 

 44 mm. — Texas, September. 



Tribe GYN^ECIINI. 



Butterfly : Heavy bodied. Antennae moderately stout but long, 

 the club slender, elongate, gradually incrassate. Palpi compact, 

 moderately slender, tapering, the last joint rather short. Wings 

 simple, subtriangular, broad, especially the hind pair at its sub- 

 truncate outer margin, entire, the hind pair sometimes with a small 

 anal lobe; cell of both wings closed by a slender vein. Last tarsal 

 joint with two rows of spines beneath. Egg : Conical, with about 

 11 very prominent vertical ribs nearly reaching the pole. Cat- 

 erpillar at birth : Trichomes of body shorter than the segments, 

 straight, delicately clubbed at apex, finely toothed. Mature Cater- 

 pillar : Head thorny, crowned by a pair of thorny spines longer 

 than the head and similar to those of the body, which are long, 

 corneous, surmounted by a whorl of spinelets as important as the 

 terminal thorn, in ranged series, one mediodorsal as important as 

 the others. Feeds on Urticaceoe. Chrysalis : Slender and elon- 

 gate, straight, tuberculate, especially at anterior extremity, bear- 

 ing a rude resemblance to that of Papilio s. s. or Thais, some of 

 the tubercles of the laterodorsal series prominent and directed 

 downward. 



Smyrna Hiibner. 



Butterfly : Body very robust. Eyes naked. Second superior 

 subcostal nervule of fore wings arising before the tip of the cell, 

 the third well before the middle of the wing and extending to the 

 very apex; lowest median nervule of hind wings produced to a short 

 lobe. Caterpillar : Only the second stage is known, showing it 

 to be similar to that of the tropical Gynsecia. (o-fjivpva, myrrh; 

 allusion wholly obscure.)
