 generally iihscnt, sonietinu's also the second. The sp(H:ies is ratlicr variable in 

 pattern individnaily. The jjosterior jiart of the disc of the forewinu;, distally of tlie 

 angulatcd antcniedian hand, is sonictiiues occupied by reddish lirowii jintclies ; tlie 

 pale border of the hindwing is often flnslied with rosy red. 



<S. Antenna shorter than in the other species, pectinate, the branches 

 long, tlie segments short, with the ventral parts strongly conijjressed. Tenth 

 segment of abdomen not essentially different from that of a'risyi, tiie tergite 

 more dilated in the middle ; the lobe of the sternite very slender. Clasper 

 (PI. XXXIV. f. 2Sj narrower than in rfrisi/i, the apex less evenly rounded ; dorso- 

 apical ridge rounded, placed somewhat obli(jue!y, appearing to be much more 

 ventral tlian in cerisi/i owing to the clasper being dilated dorsad; harjie short, rougii 

 with tubercles at the end ; the incrassate proximal part of the ventral edge of tlie 

 ]iarj)e jiroduced into a high triangular ridge, of which tiie edges are turned dorsnd, 

 so that the ridge has the ap])earance of a solid conical ju'ocess in a ventral view. 

 Penis-funnel jjniduced ventrally into a long, pointed ])rocess (PI. XXIX. f. 43) ; 

 penis-sheath strongly chitinised at the end on one side, with ticn strong coincal 

 teeth ; patch of si)ines within the sheath vestigial. 



?. Antenna not pectinate, tiie lateral expansion indicated by a snlnlursal 

 curved carina on each segment ; the segments shorter than broad or higli, laterally 

 somewhat lonnded in a dorsal or ventral view, ventrally carinate ; bristles prominent, 

 ciliae short. Vaginal plate sliort, membranaceous ; vaginal cavity large, transverse, 

 the edge incrassate at the side corners to a subglobose tubercle, anterior edge not 

 elevated. 



According to the number of blue spots in the eye-patcli of the hindwing 

 the following forms liave been distinguished :

The first and second blue spots of the eye-mark absent. 



b'. SjiJi. jamaici'iisis f. norm, yeminatii.^. 

 Synonymy see above. First spot absent, second and third well developed.

First spot very small but not absent, second and third well developed. 



We are not at all sure that the name tri})artitiis refers to this sjiecies. C4rote, 

 when proposing the name, had uo material of this third form, but based the name 

 upon information derived from books quoting verbally from Fernald, who mentions 

 in his Sp/iiiigi(lae oJ.Xeic England, I.e., that ''occasionally a third blue sjjot aj)pears 

 on the black." AVe do not know whether Fernald had himself seen " a third spot,"
