filloil lip wifli lilack sialiiiu: : fliif' i^''»'ii' contrasts in many specimens strongly with 

 tlic jiali'r, nisst't, basal and distal areas. Tbe discal and postdiscal lines are, near 

 ir, less curved than in pctiinuic, but more so than in scxia. The white dots of the 

 I'riu^'e encroaeli sometimes on the wiii<!:, being slightly enlarged basad ; they are 

 often l)arely iudicat<'d and soinethnes quite absent. Antenna obviously slenderer 

 than in sexta, slightly Ihiuuer ilinii in petuniae. First segment of foretarsus, as 

 in pi'tuniae, with fonr long and several small sjiiues exteri(U'ly. Nn pulvillus. 



cT. Tenth abdomiMal tergite rather broad, flattened above Ijefore the convex 

 end, which is hooked and pointed, and here somewhat rounded-dilated laterally ; 

 sternite rounded at end, similar in shape to that of jirtiiiuae, but the turncd- 

 nj) portion of the lateral margin more proximal, the narrowed apex therefore 

 longer. ( 'lasper rather broadly sole-shaped, ventral margin strongly oblique 

 in distal half; harjie (PI. XXXIX. f. 3. 4): ventral ])rocess rather obviously 

 hooked, the tip curving basad ; dentate process large, extending to near, or even a 

 little beyond, dorsal edge of clasper, siekle-shaped, twisted at the end, this narrowed 

 eud-part not constant in size and dentition. Tooth of penis-sheath triangular, 

 horizontal, rather shorter than in pi'tHniae. 



?. Einlitii abdominal terjj'ito not sinuate, mesially not obviously imi)ressed ; 

 sides more strongly chitinised than disc. Vaginal armatnre similar to that of 

 vrcultii, but the antevaginal lobe shorter. 



Larva: with six side-bands aeeoriliug to Peter's tiijure (Ic.) \ correct? this 

 species ? 



Pupa: tongue-case recurved, its cud resting against the nnderslde of the sheath 

 near the base (Peters, I.e.). 



Boisdnval's description of the larva and pupa, I.e., does not agree with Peter's 

 figures. 



Jiab. Costa Rica to Buenos Ayres. 



Two subspecies : 



a. P. liicrf/'i/s nuhila snbsp. nov. 



J?. Forewiug more elongate than in the following subspecies, basal and 

 discal areas much less russet, the black jiostdiscal line less cnrved ; brown bands 

 of the nnderside of the hiudwing feebler marked. 



(J. End of tenth abdominal tergite a little less convex and less hooked. 

 Clasper shorter, ventro-disfally more oblicjue ; harpe much nearer the end of 

 the clasper (PI. XXXIX. f. 3), the dentate lobe u.o;e strongly rounded, and a])ically 

 narrower. 



?. Vaginal armatnre : antevaginal lobe short (not sinuate), the oblique ])roximal 

 ridges strongly turned frontad, almost in a plane with the lobe (PI. XX. f. 5). 



Larva aiid pupa not known. 



Length of fore wing : c^, 40 mm. ; ?, 43 to 44 mm. 



Ilab. Costa llica, 1 c?, 2 ? ?. We have some donbts about the correctness 

 of the locality. 



The dift'erence in the length of the clasper and in the position of tlie harpe 

 between this and the following form is very remarkable ; as we have only one 

 mdividnal of the S sex, we do not know whether the difference is eonstant.
