1864 BUTTERFLIES BEYOND NEW ENGLAND. 



costal border is more or less infuscated; the discal stigma consists of two mod- 

 erately broad bars of velvety black, the upper and outer at the extreme base of 

 the lower median interspace, following the median nervure, the lower and inner con. 

 nected with the lower inner corner of the upper at its own upper outer corner, and 

 traversing the medio-submedian interspace in a line nearly parallel to that of the upper 

 portion of the stigma, but bent in the least possible degree downward ; the two por- 

 tions of the stigma are equal and each rounded at either end and about three and a 

 half times longer than broad with slight individual variation. Uiml icings with the 

 disli more or less marked with fulvous tawny in the centre, leaving an extremely 

 broad margin arouud the whole, and invariably cut distinctly by blackisli fuscous ner- 

 vules ; it is occasionally reduced almost entirely to a single longitudinal ray in the 

 subcosto-median interspace, where, when best developed, it is almost always more dis- 

 tinct than elsewhere, and extends from the apex of the cell more than half way to the 

 margin of the wing; the whole disk of the wing is, moreover, heavily clothed with 

 dark tawny hairs; fringe pallid, mixed with brown scales which nearly supplant the 

 paler ones on the upper half of the fore wing. 



Beneath dark brown, more or less enlivened with a sprinkling of tawny scales. 

 Fore wings sprinkled with tawny scales having more or less of an orange tinge, espe- 

 cially above the median nervure, beneath which, previous to the extra-mesial band, 

 which is less conspicuously repeated beneath in both sexes as in the female above, the 

 wing is deeply infumated with blackish or blackish brown, which also follows the 

 inner margin nearly to the tip and suflTuses more or less the apical half of the median 

 and submedian interspaces in both sexes, though tlie latter more commonly in the male 

 than in the female ; outer margin marked with a black brown thread and the fringe 

 concolorous with the wing or a little more pallid on the lower half. Sitid loiyigs hav- 

 ing the same general color as the upper half of the fore wings, excepting that a broad 

 longitudinal belt of yellow tawny follows the subcosto-median interspace from the 

 extremity of the cell more than half way to the margin, beyond which it gradually 

 fades out, and another the whole of the medio-submedian interspace from base to 

 margin, while the inner margin beneath this is slightly yellower than the main ground 

 color; in addition the veins are frequently marked with yellow, but this feature is 

 more common in northern individuals than in southern, those from Florida being fre- 

 quently almost uniformly flecked with fulvous scales throughout, showing little or no 

 sign of the broad yellow rays or of any distinction of nervures. Expanse of wings, 

 S , 39-44 mm. ; ? , 42-49 mm. Described from 5 (J , 5 ? . 



I judge that the description of the caterpillar referred to this species by Chapman does 

 not belong to it because I have received from him named specimens of the imago from 

 Florida which do not belong to this species but to an allied one which is intermediate 

 between Limochores pontiac and Limochores arpa, sent me many years ago by Mr. 

 Edwards under the specific name of pallas, but which has never been described under 

 that name. Specimens of dion, kindly sent me by Professor French, compared with 

 specimens from Florida, which had been compared at the time of its description with 

 the type of Edwards's palatka, show them to be the same species. 



The distribution of this butterfly is evidently little known, since it has 

 been found only in the western Mississippi states — eastern Nebraska, 

 northern Illinois and Indiana — and at Hamilton, Ontario, and then in nor- 

 thern Florida. Nothing is known of its earlier stages.
