'I'm: (JENUS FOHIMKIAKIIIS RIlxaVAY. 



terinediiitc but di'liiiiio and very cDUsUiut clianictcrs, which 1 hiive 

 named F. xaiiuuttit^. Of F. crissalis I liavo seen but one specimen; of 

 /'. (Dudi.s only two (pnssiblv three), and mme of F. rnjipecfiis or its near 

 ally (possibly not dilVerent), F. Iliordch-Hx. 



In tlie ease ot lew s])eeiinens of a jiiven form, or wliat are snpjtosed 

 to be tli(^ same form, it is of eouisc, diriicnlt to tell whether certain ob- 

 \ions dirfereiiees represent indi\i<lnal or local vaiiations; bnt, as has 

 so often been theca-so in otlicr instances, it has been Ibnnd tliat tiie 

 larger tiu", series of specimens the nu)re uniform are their characters, 

 and conseiiuently tlu' various local foi-ms thns rei)resented can be more 

 easily dcliiu'd. 



My tliani<s are due for tlie loan of specimens to the authorities of the 

 Museo Nacional de ('oslai IJiea, the IJoslon Society of Natural History, 

 the American Museum of Natural History, New York City, and JNIessrs. 

 Salvin and (Jodman, of London, Enj;land, all of whom have lent me 

 imjiortant speciniens, without w liich no satisfactory eouelusions could 

 Lave been reached. The considerable series of specimens which J have 

 thus been able to brinj^- toj^ether suj^g'ests very stron.yly the probability 

 thati'\ HHal'tH (Lafr. .S: B'Orb.), F. crissaHs (Cab.),-?'', hoffmanni (Cab.), 

 F. monUUjcr Scl., and the three forms which I am obliged to describe as 

 new, are not distinct species, but merely more or less dilferentiated 

 g-eo«;rai)hical races of one widely distributed species, which ranges from 

 scmthern Mexico to l>olivia; and that when we have si )ecinuMis from 

 the very considerable areas of continental tropical America from which 

 exam])Ies of the genus have not yet been examined it will become nec- 

 essary to characterize and nanu' still other forms. However this may 

 prove to be, 1 lind that the ten forms of the F. uuuHh section treated 

 below can easily be made out from the comparatively scant nmtei'ial 

 which 1 liave been able to compare: *
