P. agassus Mob. Forewing jet-black, hindwing black with a very much indented distal margin. Beneath ayassus. 

 the forewing is black with a violet reflection, in the marginal area bluish-lilac, at the proximal angle lighter 

 ferruginous. Hindwing black, from the cell to the distal margin dark lilac with 4 metallic blue spots behind 

 the cell towards the apex, the 2 lower ones sagittiform, the others .strigiform. Expanse of wings: 26 mm. 

 Massauary. 



P. bobae Weeks is above velvety blackish-brown with an indistinct darker band, hindwing at the holae. 

 costal margin somewhat lighter. Beneath somewhat lighter, thereby the dark bands beccn:e ."lOmewhat more 

 distinct; inner-marginal part very light. Hindwing as above. Expanse of wings: 27 mm. Venezuela (Suapure). 



P. leucopogon Plotz (187 f) has above on the base of the wing and on the body a faint greenish reflection, leucopogon. 

 Beneath lighter brown, on the forewing two basal thirds are darkened, the distal third is lighter, with 3 small 

 light subapical spots. Hindwing with a darkened base and a dark semi-transverse band from the middle of 

 the costal margin to below the cell, behind it projecting somewhat towards the margin. Venezuela (LaguajTa). 



P. corisana Plotz (187 g) is above uni-colouved black; beneath lighter, more brownish, especially on ccrisana. 

 the forewing analwards ; here there are in the disc 2 whitish punctiform spots and above them 3 subapical ones. 

 Hindwing likewise uni-coloured without markings, only at the proximal margin somewhat lighter. From Surinam. 



P. sobrinus Schs. Above dark brown, fringes blackish, distally grey. Beneath dark brown, the fore- solrinvs. 

 wing is lighter, with a postdiscal bent row of very small grey spots; the hindwing shows a postdiscal row of 

 dark ochreous-yellow spots. Expanse of wings: 27 mm. Rio de Janeiro. 



144. Genus: Muasiiioiis G: & S. 



Antennae longer than half the costal margin, body slender. Middle tibiae bare. The ^ shows a tripartite 

 stigma which is rather inconspicuous: a faint scent-stripe along the median between the two veins, a shorter 

 one below it and a longer one on the submedian. 



M. patage G. <b S. (187 g) is above monotonously blackish-brown, beneath somewhat lighter, the pa^"9e- 

 forewing at the proximal margin and anal angle still lighter ; costal margin, apex and hindwing are dusted darlc 

 red. From Mexico and Panama. * 



145. Genus: Metiscus G. & S. 



Different from the preceding by the ^ scent-organ: from the rise of the upper median vein a bent scent- 

 scale stripe runs obliquely to the rise of the lower branch, below it there is a short stripe. 



M. atheas G. ds S. {1 = infuscata Plotzt) (187 f). Above uni-coloured blackish-brown, the narrow aihcas. 

 bent stigma equally coloured. Beneath as above, only the forewing at the anal angle lighter, fringes grey. Mexico 

 to the Amazon, Trinidad. 



146. Genus : Methiou G. cfc S. 



Costal margin somewhat more convex than in the allied genera; middle tibiae bare; the ^ is without 

 a scent-scale stripe. The distal margin of the abdominal fold is long-haired. 



M. melas G. & S. is monotonously blackish-brown, beneath somewhat more reddish, at the proximal melas. 

 margin and anal angle of the forewing lighter. Palpi intermixed with golden yellow hair. From Guatemala. 



147. Genus: Thargella G. & 8. 



The antennae are ^/g of the length of the costal margin; forewing short and broad with a very convex 

 costal margin. Stigma absent. The proximal margin of the abdominal fold is long-haired. 



Th. fuliginosa G. <Ss S. Above blackish-brown, beneath red-brown, the forewing analwards lighter, fuliyinosa. 

 Palpi golden yellow. Nicaragua to Colombia, British Guiana and the Amazon. 



148. Genus : Miiasitheiis G. & S. 



Antennae half as long as the costal margin; costal margin of forewing slightly bent. Middle tibiae bare, 

 a stigma is only present in cepMs: a short stripe above the lower median vein, a longer one below it and a 

 still longer one on the submedian. 



M. cephis G. cfc S. Above uni-coloured blackish-brown, beneath with a somewhat purple tint. Smaller ccphw. 

 than the very similar Mnasalcas uniformis with a different stigma. Distinguished from the folloMing species 

 by a longer terminal joint of the palp and different genitals. Mexico to Guatemala.
