the cell, four others resting on the branches of the median and 

 on the radial nerviu-e, the outer of these small, the others succes- 

 sively larger, except the last, -which is almost linear. Cilia all 

 spotted with white. 



Head black, palpi and occiput red. Thorax black, with a red 

 collar below spotted with red. Abdomen fuscous, two spots on 

 each side near the base, and margin of last segment below red. 



From Trinidad.

Above. — Anterior wings black, with a narrow macular whitish 

 band commencing indistinctly upon the costa, traversing these 

 wings considerably beyond the discoidal cell, and terminatmg on 

 the disc of the posterior wings, where the last spot is divided into 

 three parts by the disco-cellular and the last branch of the me- 

 dian ner\Tire. Posterior wings black, sprinkled beyond the mid- 

 dle with a few bluish scales, deeply dentate, the third tooth from 

 the anal angle prolonged into a long spatulate tail, marked, in 

 addition to the white fascia, with three somewhat rose-coloured 

 spots placed transversely between the abdominal margin and the 

 termination of the macular band, which is here slightly tinted 

 with rose-colour. Beyond these arc three lunules of the same 

 colour, one above the anal angle, the others close to the margin, 

 between the first, second and third branches of the median ner- 

 vm'c, succeeded by two sigmoid red spots, and near the anal angle 

 by a whitish one. Anal angle itself red. Cilia white, except at 

 the extremity of the dentations. 



Below paler than above, and in addition to the markings of the 

 upper sm-face there is a narrow white line near the outer margin 

 of the anterior wings, extending from the fourth branch of the 

 median nervure to the anal angle, and on the posterior wings an 

 indistinct macular Hexuous white band preceding the marginal 

 series of lunules and spots. 



Head black ; palpi yellow ; thorax black, spotted below with 

 yellowish ; abdomen fuscous, v.ith a yellowish lateral line. 



From the west coast of America (probably of New Granada or 

 the Ecuador) . Closely allied to P. Hectorules, but may be easily 

 known from it as the macular white baud begins nearer the apex 

 of the anterior wings, crosses the Aving at some distance beyond 

 the discoidal cell, and is continued nearly in a direct line to the 

 disc of the posterior wings, only a shght portion being within 

 the discoidal cell.
