246 PROCEEDINGS OP THE AMERICAN ACADEMY 



hind wings nowhere approximate. Legs delicate and short, the 

 under surface of last tarsal joint with two rows of spines, the 

 others with four. Egg aud Caterpillar at birth: Unknown. Mature 

 Caterpillar ; Coronal spines of head exceedingly long, briefly and 

 abundantly aculiferous, slender, tapering. Body armed only with a 

 dorsal series of erect tapering filaments on a few segments. Feeds 

 on the Fig family and Anacardiaceoe. Chrysalis : Not very elon- 

 gate; frontal projections consisting of long slender tapering fila- 

 ments, similar ones (flexible ?) crowning the basal wing tubercles, 

 and still others of varying length forming a dorsal series on the 

 abdomen. 



Makpesia Hiibner. 



Butterfly : Body small for the ample wings. Fore wings api- 

 cally produced, often falcate ; second superior subcostal nervule 

 arising at the end of the cell, the third far toward the tip of the 

 wing; hind wings with very long tails. Fore tibia and femur of 

 male of equal length, the tarsus not half so long; fore tibia of 

 female much shorter than either femur or tarsi. Mature Cater- 

 pillar : The dorsal filaments are arranged on alternate abdominal 

 segments beginning with the second, the last on the eighth being 

 curved backward apically (much like the anal horn of a hawk-moth 

 caterpillar) and a little longer than the others. Chrysalis : Com- 

 pact, laterally compressed, with dorsal and anal carinse; head very 

 broad, bearing outwardly a pair of slender filamentous processes 

 much like those of the caterpillar; and similar processes appear on 

 the mesonotal and basal wing tubercles as well as a dorsal series 

 on the second to the eighth abdominal segments, the first abdom- 

 inal, the thoracic, and the cephalic filaments longer than the rest; 

 cremaster bent downwards, the surface of attachment elongate, 

 parallel to venter. (Marpesus, nom. propr. ) 



§ M arpesia proper. Butterfly : Costal margin of fore wings very strongly 

 arched; hind wings emarginate at upper outer angle, but yet with anterior por- 

 tion longer than posterior part of fore wings and about as long as their own 

 inner margin apart from the lobes ; tails subspatulcte. Prevailing colors tawny. 

 Caterpillar feeds on Ficus and Anacardium. 



Marpesia peleus Sulz. (Pap. thetys Fabr. ; Pap. petreus Cram. ; 

 Timetes eleucha Edw.) Butterfly : Upper surface of wings tawny, 

 crossed by three common, straight, slender black or dark ferru- 

 ginous stripes, the inner not reaching the margin of either wing,
