FROM MEXICO 



BY HARRISON G. DYAR. 



The following larvae have been obtained by the Bureau of 

 Entomology from Mr. W. Gugelmaun, bred by him at Mis- 

 antla, State of Vera Cruz, Mexico. 



PAPILTONID^. 



Papilio belesis Bates. 



Larva. Head rounded, slightly bilobed, shining black, with pale 

 secondary hairs on the lower parts of the sides. Body subcylindrical, 

 uniform; a subdorsal row of short papillae. Black; a large white 

 dorsal saddle on joints 8 and 9, incised before, the points running 

 down to the spiracle on joint 8; two rows of round red spots, stig- 

 matally and subventrally. 



Food plant: Anona. 



NYMPHALIMS. 



Gynaecia dirce Linnaeus. 



Larva. Head strongly bilobed, each lobe with a long apical horn 

 with short, irregular branches; head shining black, with several 

 small inconspicuous horns especially laterally, all these as well at the 

 large apical horn, pale yellow. Body cylindrical, tapering only slightly 

 at the ends; rows of spinose processes, each process with a straight 

 shaft and three or four branches, collected into a subapical crown; 

 joints 2 has only a small subdorsal process; on joints 3 and 4 are two 

 rows, subdorsal and lateral; on 5 to 12, three rows; on joint 13, a sub- 

 dorsal pair only; all the processes paired. Body black, the processes 

 contrasting light yellow; laterally on each segment anteriorly an oval 

 dale yellow patch, small on joints 2 to 4, large on 5 to 12, none on 

 joint 13. 



Eunica modesta Bates. 



Larva. Head angularly bilobed, roughened with conical secondary 

 tubercles bearing pale seise; pale orange color, a broad black band 

 across the mouth, with irregular upper border, reaching nearly to the 

 apex of clypeus. Body cylindrical, slender, a little enlarged at joint 

 12 and the sides of joints 3; at the enlargements are low, degenerate 

 processes, a dorsal cone with short branches and a subdorsal pair on 

 joint 12, a collection of lateral tubercles on joint 3, these colored 

 black. Elsewhere no processes are developed, but the body is rough- 

 ened with scattered black secondary tubercles, bearing rather long 

 dark setae, and arranged in transverse lines. General color dull or-
