Melitaea Bollii. 



Female. — Expands 1.5 inch. 



Upper side black spotted with fulvous ; both wings have a submar- 

 ginal row of ochrey-yellow points or small spots, complete on secon- 

 daries except at the angles, but present on primaries only on middle 

 of the wing; preceeding this is a common extra-discal row of small 

 orange spots, largest on primaries, and pale colored next costa ; and 

 this is followed by a common series of long and narrow, pale colored 

 spots, those on secondaries arranged in a regular curve nearly parallel 

 to the hind margin, but on primaries bent at a sharp angle around 

 end of cell ; cell of primaries nearly occupied by fulvous, there being 

 a spot of dark color next the arc, then a pale oblique stripe, and next 

 a dark patch in middle and a small one at base ; below cell a rounded 

 pale colored patch and stripe toward base ; secondaries have the cell 

 fulvous externally, and nearly bisected by a black stripe, and near 

 base and below cell fulvous scales; fringes alternately and equally pure 

 white and black. 



Under side black, spotted with buff and fulvous ; both wings have 

 a submarginal series of large buff spots, square-edged behind and 

 leaving a narrow even black stripe between them and the margins, 

 those of primaries mostly crenated, or at the apex elongated, but 

 those of secondaries mostly sub-quadrate, and at the angles triangular; 

 the other markings on primaries are much as above, but enlarged, and 

 the cell is quite filled with fulvous, except the black edging to the 

 oblique stripe, and a longitudinal curved line near base ; secondaries 

 have an extra discal transverse row of oblong fulvous spots, and a dis- 

 cal series of buff spots of same shade as the submarginal and corres- 

 ponding to those of upper side ; a large deep fulvous patch covers the 

 outer half of cell and extends by narrow offsets to the costal margin on
