THE BUTTERFLIES OF NEW ENGLAND. 



very slight curve, its concavity outwards ; tlic upper lialf is the most nearly continuous ; 

 there is a narrow, straijrlit, submarfiinal stripe of steel colored scales, distant by lialf 

 an interspace's width from the outer border, edged with a few discontinuous blackish 

 scales on the inner side and occasionally a few on the outer side; following it 

 inwardly is a series of black dots like those of the upper surface; fringe as 

 above. Hind wings with four series of black streaks like those above and similarly 

 situated, the first indistinct; the fourth commences in the costo-subcostal interspace, 

 just beneath the tip of tlie costal, crosses the upper subcostal interspace by a full 

 interspace's width further outward, resumes its former course in crossing the lower 

 subcostal and again leaps to the same extent outwardly at the subcosto-median and 

 upper median interspaces, after which it again returns to its former direction and con- 

 tinues interruptedly but with a uniform direction to the middle of the inner border; 

 there is a transverse series of moderately slender, interruptedly continuous, steel col- 

 ored lunules, scarcely bordered with black, one in each interspace, in the same rela- 

 tive position as the transverse series of lunules in the fore wing; as tliere also, the 

 scries is Ijent at the middle median nervule and the general direction of either half is 

 a slight curve, its concavity outwards ; a submarginal steel colored stripe, followed 

 inwardly by a row of black dots, just as in the fore wing; fringe as above. 



Abdomen above blackish mingled with grayish scales, below briglit saffron. Male 

 abdominal appendages (34: 10, 11) with the lateral arms of the upper organ bent 

 strongly, the basal portion stout and swollen, the distal tapering with great regu- 

 larity to a fine point, bent slightly upward. Apical half of clasps bent about the 

 middle so as to be directed straight backward, instead of slightly upward and inward 

 as previously, the tip Ijlnnt and rounded ; basal finger about as slender as the distal 

 portion of the lateral arm above, but bluntly pointed. 



Described from 2 S . 



Secondary sexual distinctions. On the upper surface of the wings I have 

 found, in the male and not in the female, a very few untoothed scales so closely re- 

 sembling others in similar situations in the lower Nymphalidae that I think it prob- 

 able they are androconia (46: 17); they are of a quadrangular form, scarcely 

 enlarging apically , three times as long as broad, the apex truncate with rounded angles, 

 the basal lobes distinct, broad, well rounded; they measure .15 mm. in length or 

 are slightly larger than the normal scales. 



This very rare butterfly has only been recorded from two or three 

 localities, but these are so widely distant that we may hope for its 

 detection at any point within tlie limits marked on our map (22 : 8). It 

 was first discovei'ed by Messrs. Grote and Robinson in Coldenham, 

 Orange Co., N. Y., and has since been taken in Michigan (Austin in 

 coll. Univ. Mich.), the township of Ohio, 111. (Morrison), New Jersey 

 (Edwards) and Coalburgh, W. Va., a single specimen or two (Edwards). 

 I have also seen specimens from Tehuantepec (Sumichrast, Mus. Bost. 

 soc. nat. hist. ) which seems indistinguishable and which in all probability 

 is Godman and Salvin's laverna, an uncharacterized species, which they 

 rc|)ort from Mexico (Presidio), Honduras, Panama (Volcan de Chiriqui,
