FLACILLA; CYMAENES. By Dr. M. Draudt. 983 



D. rubrinota Drc. (189 f). Above blackish-brown, between the veins lighter. Beneath greyish-brown, rubrinoia. 

 on the forewing with a yellowish, black-veined postdiscal area. Hindwing greyish-brown, with black veins 

 and iaternerval streaks with a brick-red costal margin and inner-marginal stripe and a brick-red longitudinal 

 diffuse patch along the lower margua of the cell. Eyes red. The $ is also above postdiscally lighter yeUo\^'ish- 

 white. Peru, Bolivia. — In Colombian specimens: f. acraea Plotz (189 e) there is only the red stripe below the acraea. 

 cell, those at the costal and proximal margins being absent. 



D. pruinosa Plotz (189 e). Above monotonously blackish-brown with a grey stigma. Beneath the pruinosa. 

 forewing, towards the apex at the distal margin, is dusted with violettish-bluish like the whole hindwing except 

 the costal part; some small, postdiscal, brownish diffuse spots. Brazil (Chapada). 



168. Genus: Flacilla G. & S. 



Antennae of two thirds of the length of the costal margin with a slender club and an almost semicircularly 

 bent apex; terminal jomt of the palp long and pointed. Forewing long with a concave costal margin. The (J 

 exhibits a scent-spot from the base of the median to the rise of the lower branch, a stripe below it and a third 

 longer one on the submedian; the hindwing shows long hair in the anal fold. 



F. aecas Cr. (189 d) is easily recognizable by the steel-blue, white-veined ^hindwing beneath with aera.i. 

 a submarginal row of whitish dots; also the costal margin and apex of the forewing is steel-blue; the proximal 

 margin of the hindwing is broad brownish-grey. Panama to Brazil; Trinidad. 



F. coatepeca Schs. Head reddish-brown, collar and thorax violettish-brown.. Wings dark brown, crxdepeca. 

 forewing with a small, white-hj^aline longitudinal spot in the cell, a large spot below it, 2 smaller ones farther 

 distally and 2 subapical, small, quadrangular spots. Beneath dark brownish-red, on the forewing the cell and 

 proximal margin blackish, with the spots as above. Hindwing with a blackish-brown inner-marginal part. 

 Expanse of wings: 42 mm. Mexico (Coatepec). 



F. ergola Schs. Above brown, the basal third of the costal margin of the forewing as well as the anterior ergola. 

 body more red- brown; a large spot between the median veins, and a smaller one above it and farther distally 

 are yellowish-hyaline. Beneath the forewing is black, the costal margm, apex and distal margin are red-brown. 

 Hindwing reddish-brown, at the costal margin darker, with a broad, dark postdiscal shade and a light violet 

 cell. Expanse of wings: 37 mm. Novo Friburgo. 



169. Genus: Cymaenes Scddr. 



Antennae long and slender; terminal joint of the palp long and erect. Body slender, middle tibiae 

 bare, in the ^ a scent-organ. 



C. malitiosa H.-Schdff. (= lycaenoides Plotz) (189 e) is above of a plam blackish-brown, beneath niaUtiosa. 

 lighter, the forewing at the costal margin and apex watered red-brown like the whole hindwing which exhibits 

 a broad, irregular dark transverse band being interrupted in the middle and broadest at the costal margin. 

 Mexico to Costa Rica and Cuba and Trinidad. Very closely allied to silius (189 f) from which, however, it is 

 easily separated by the hindwing beneath. 



C. lutuletlta E.-Schaff. (189 e) is above like the preceding. Beneath lighter, the hindwing whitish luhdenla. 

 and watered with brownish-red, at the costal margin broadly red-brown, in the middle of the lower margin 

 interrupted by a light streak of the ground-colour. Panama to Colombia and Venezuela. 



C. silius Latr. (antistia Plotz) (189 f). Blackish-brown with a reddish-yellow oblique band from the silius. 

 proximal margin before the base to the apex of the forewing, where it ends narrowed. Costal margin strewn 

 with ochreous. Beneath the costal margin is broader reddish-yellow, otherwise the same; the hindwing is 

 dark ochreous-yellow, strewn with blackish- brown. Mexico to Brazil. Allied to lunata, but the reddish-yellow 

 band is narrower, the hindwing beneath lighter. 



C. lunata Plotz (= berus Mob., insidiosa Mob.) (189 f) is very similar, but the reddish-yellow is much lunata. 

 more extensive than in silius, so that only a cellular longitudinal stripe and the dentate margin remam dark. 

 Beneath red-brown, towards the proximal margin light ochreous or grey. Hindwing ferrugmous-brown, in 

 the disc and at the distal margin dusted with lilac-grey. The species is very variable; specimens from Costa 

 Rica are on the forewing beneath analwards ochreous-yellow, on the hindwing beneath with a more or less 

 distinct, narrow, dark band proceeding from the costal margin near the apex. Costa Rica to Brazil. — f . silene silene. 

 Plotz is above darker, the reddish-yellow reduced and more red-brown, beneath also darker, on the forewing 

 without the submedian lighter part. 



C. syraces G. <fe S. (189 f). Forewing above reddish-yellow with a large, triangular basal spot and syraces. 

 quadrangular subapical spot of a blackish-brown colour and a broad, similarly colom-ed margin. Hmdwing 

 below the broad black costal margin in the disc strewn with ferruginous yellow. Beneath the forewing is the 

 same, the hindwing grey or ochreous-yellow, strewn darker, with a dark brown triangular costal-marginal 

 spot and a smaller one below the cell-end; distal margin broadly darkened. Mexico to Guatemala. 



C. pericles Mschlr. (189 g) is above similar, but more extensively yellowish-brown, especially on the perides. 

 hindwing. Beneath quite different, the hindwing being monotonously yellowish-brown with a narrow black 

 marginal line. Forewing coloured and marked as above. Colombia, Venezuela, Trinidad.
