20 Mr. E. Meyrick's JDescriptions of 



narrow, costa anteriorly gently arched, behind middle somewhat 

 sinuate, apex rounded, termen rounded, rather strongly oblique ; 

 light bronzy-brownish ; an oblique dark fuscous spot on base of 

 costa, nearly followed by a similar larger spot ; beyond this an 

 oblique white patch on costa reaching to i and separated posteriorly 

 by a dark fuscous strigula from an oblique white strigula followed 

 by a dark fuscous patch suffused posteriorly ; beneath the white 

 strigula is some yellowish suffusion ; from between the first two 

 dark costal spots proceeds an oblique irregular-dentate pale partly 

 whitish-tinged line to near dorsum, basal space before this mixed 

 with dark fuscous, with a dark fuscous spot on dorsum ; a thick 

 irregular dark fuscous longitudinal streak from beyond this above 

 middle of disc to |, cut by a curved whitish line about middle and 

 another at f, and limited posteriorly by a deeply curved-dentate 

 white line causing its extremity to be furcate ; an elongate dark 

 fuscous spot on fold before middle, edged with whitish posteriorly ; 

 apical fifth of wing shining silvery-metallic, including a transverse 

 dark fuscous spot beneath costa, below which is a yellowish-white 

 ring resting on lower part of termen but incomplete anteriorly ; 

 a yellowish-white line round posterior part of costa and termen : 

 cilia pale brownish, tips whitish, round apex with a dark fuscous 

 basal shade. Hind- wings fuscous ; cilia whitish-fuscous, with a 

 fuscous subbasal shade. 



Bolivia, Songo; one specimen. 



PSITTACASTIS, n. g. 



Head with appressed hairs ; ocelli present ; tongue developed. 

 Antennae almost 1, in ^ serrate, very shortly ciliated, basal joint 

 elongate. Labial palpi very long, recurved, second joint with 

 dense appressed scales, terminal joint longer than second, moderate, 

 pointed. Maxillary palpi short, filiform, appret^sed to tongue. Pos- 

 terior tibiae clothed Avith hairs above. Fore-wings with lb rather 

 short-furcate, 2 and 3 curved, 2 from near angle, 3 from angle, 4 

 straight, 5 diverging, 7 and 8 stalked or coincident (eurychrysa), 7 to 

 costa, 11 from before middle. Hind-wings 1, elongate-trapezoidal- 

 ovate, cilia f ; 3 and 4 connate, 5 somewhat approximated, 6 and 7 

 remote, rather diverging posteriorly. 



Type F. tricrica, Meyr. Allied to Idioiihantis, Meyr., 

 which it resembles in the peculiar terminal excavation of 

 the fore-wings ; in Idiocrates this acquired character has 

 been again lost, but with some resulting distortion or 

 displacement of the apex of wing.
