ARDARIS; METARDARLS; GRANILA; JEMADIA. By Dr. M. Draudt. 843 



6. Genus: Ardaris Wts. 



Distinguished from the preceding genus by a well developed middle radial of the hindwing, rising from 

 the middle of the transverse vein. The posterior tibiae likewise show only 1 pair of spurs. Only 1 species: 



A. eximia Hew. (164 e) is a smaller, very easily recognizable species, above black with an oblique '■.ehiiia. 

 band of 7 reddish-yellow spots and one behind the cell; the hindwings are diaphanous light yellow, in the disc 

 with a slight red-brown tint and a black marginal and discal band. Venezuela. 



7. Genus: lletardaris J\Iab. 



Very much like Ardaris from which it differs by 2 pair of spurs of the posterior tibiae, and the middle 

 radial of the hindwing rising nearer to the lower radial vein. Likewise only one, though variable species: 



M. cosinga Hew. (164e) has light-yellow, more or less grey-dusted forewings with thick black ro.<:hi(j(i. 

 veins, a broad black distal margin and a dentate discal band interrupted between the median veins. The long- 

 haired black thorax shows 2 light-yellow longitudinal stripes; head red, with black spots, anal tuft red. — 

 f. obscura Mab. has entirely black wings, the light yellow {)atches are visible only beneath. — In f. sangulnea ohm-ura. 

 Mab. the cell-spaces are of a deep red instead of light yellow. Bolivia. Peru. sanyuinea. 



8. Genus: Ciiraiiila Mab. 



Greatly approaches the following genim. I emodia, also exteriorly with respect to the colour and marking. 

 The chief difference is the petioled rise of the upper median and lowest radial vein from above the lo\\er cell- 

 angle on the hindwing. Only one, sexually somewhat dimorphous species: 



G. paseas Hew. (= $ albimacula Mab. &• BouU.) (163 a). Above black with light-blue dusting )>oscas. 

 at the base, oblique subbasal band and antemarginal spots; the discal oblique band and 2 spots towards the 

 apex are light yellow in the J, white in the $, like an oblique band in the costal-marginal area of the hindwing. 

 From Brazil. 



8. Genus: Jeniadia Wts. 



A very comprehensive genus, in which it is rather difficult to define the species owing to the extra- 

 ordinary resemblance among one another. Moreover, there are 2 series parallel to each other, one of which 

 shows 4 white dots on the prothorax, the other exhibiting a white transverse streak instead. In order to facilitate 

 the definition we keep to Mabille's division of the groups into ,,punctati" and ,,lineati". The Jemadin are 

 robust animals with white or blue marking and hyaline spots. The hindwings are often remarkably small, in the 

 cj(^ often with tooth-like projections on the inner-marginal and lower median vein, above them mostly with 

 a deej)ly concave excision, and between the upper radial and subcostal vein often with an obtuse projection; 

 more rarely the hindwings are quite round. The middle radial vein is absent, the lower one comes fi'om the 

 lower cell-angle, the upper median vein below it separately.

J, hospita Btlr. (166 b) has, like the following species, a rather round, only feetily undulate distal Iwsitila. 

 margin of the hindwing. A characteristic mark of this species is the hindwing exhibiting on its black ground 

 only one blue discal band and 3 fine, blue inner-marginal rays; the latter are all developed the same, diverging 

 distally, the most proximal ray, extending to the proximal margin, is parted by a fine black longitudinal stripe. 

 From Colombia and Brazil. — f. pseudognetus Mab. from ('olombia is larger, the blue oblique stripes at the p.ti'ii(io,/u<- 

 base of the forewing are extinct, the narrow marginal band coherent; on the hindwing the most j)roximal ray 

 of the inner-margin is shorter than the middle one. — f. imitator Mab. (163 c) (= dorylas Plotz, vulcanus Hew., 

 paulensis Schs.) from Bolivia is above much blacker, the basal bands of the forewing quite extinct or absent, 

 the marginal band brolven up into spots; the postdiscal hyaline spot is absent altogether, or it is replaced by 

 2 minute hyaline dots. On the nearly quite black hindwing the middle inner-marginal ray touches the marginal 

 band. — f. ulyxes Plotz (163 c) represents the species farther up to the north as far as Surinam; on the forewing »^/.ir.s-. 

 the basal oblique band is extinct, the distal one quite narrow and slightly concave distally; the marginal band 

 extends coherently to the postdiscal hyaline spot, then it makes a break and forms 2 small spots as far as 

 the small apical spots; the inner-marginal rays of the hindwing are strong and broader than in the other 

 forms. — Although these 4 forms are reported to exhibit slight differences of the sexual organs, yet I should 

 take them to be a very variable species; the separation grows still more difficult, if there are very large
