23. Emesis toltec. nov. sp. 



Upper surface dull reddish-ochreou9 brown ; a broad transverse paler band 

 occupies the middle of both wings, the space between it and the base tra- 

 versed by numerous transverse waved lines, made up of many connected 

 dishes and lunules; beyond the broad ceatral belt there is a confluent row of 

 darker lunules, widest on the costa, aad gradually tapering to the abdominal 

 margin ; after these there is a submarginal row of rounded dark-brown spots, 

 of the same range as the preceding; fringe brown ; expanse 1*5 inches. 



Primaries have the apex produced, and outer margin sinuated ; secondaries 

 rounded. 



Umieiiieath ochreous-yellow, with the spots of above repeated in ferrugi- 

 eous, a large patch of that color at the apex of the primaries, and another 

 acmss their middle; a faint ferruginous tinge at apex of secondaries. 



Hab. Mexico. (Coll. Wm. H. Edwards.) 



Very distinct from any of our described species. 



24. Synchloe qcehtala, nov. sp. 



Upper surface black ; an abbreviated band of four ovoidal white spots runs 

 from the costa across the end of the cell of the primaries ; a transverse curved 

 low of seven minute white spots beyond the short band, and a larger white 

 spot near the middle of the outer margin ; secondaries with a small red spot 

 near the anal angle, sometimes indistinct; fringe black cut with white; ex- 

 panse 1-38 inches. 



Under surface brownish black; primaries spotted as above, but with the 

 markings enlarged and with two additional white spots on the outer margin ; 

 costa red at the base. Secondaries with a broad yellow mesial belt, extend- 

 ing from the costa neatly \o the first median veinlet ; a submesial transverse 

 row of minute white spots, a large red spot at the anal angle, and three white 

 lunes on the outer margin, of which two are close together at the apex, and 

 the third on its lower half. 



j? 0( i,. .,, .,-t B ritpni np black ; legs reddish. 



Hal. Mexico. (Coll. W. H. Edwards.) 



This is the lea?t species of the interesting genus Synchloe ; it approximates 

 most nearly to Hippodrome, although still very distinct, and less than half its 

 Bize. 



25. Papilio Eridamas, nov. sp. 



Male. Upper surface black, faintly glossed with bluish-green ; a long streak 

 followed by an oval spctf, both yellow, or yellowish-green, below the upper 

 third of the costa of the primaries ; a submarginal row of similarly colored 

 spots near the outer border, becoming obsolete towards the apex; primaries 

 sinuate; secondaries dentate, with a short elongated tooth, emarginatious of 

 both yellowish. 



Secondaries with a submarginal row of seven large crimson spots, widely 

 distant from each otlnr, of which the first three are oval; the fourth seuu- 

 ovoid and larger ; the fifth, and largest of all, is almost rectangular, with an 

 indentation upon the lower extremity; the sixth intermediate in size betvyeea 

 the tourtb and fifth ; the seventh is nearly square, about the size of the third, 

 and wi h indentations on both sides; these are immediately followed by, and 

 connected with yellowish spots, largely so after the first and gradually reducing 

 to obsolescence under the last ; expanse 3 5 inches. 



Under surface lustrous brown, paler at the tips of the primaries, upon which, 

 also, the subcostal ovoid of the upper side is indistinctly reproduced. 



Secondaries with three crimson spots at the base, and a submarginal row 

 of small, brilliant spots of the same color, the three nearest the anal angle be- 

 ing chevron-shaped, and the other four semi-lunate. 



Body black ; four spots upon each side of the thorax below, one at the in- 

 sertion of the abdomen, and a continuous series on its lower part, not, how- 

 ever, extending upon the anal valves, all crimson.
