PACHYNEURIA; PRAXIS; SOSTRATA, By Dr. M. Draitdt. 901 



A. Cyclops Mab. from Colombia and Guatemala has very broad forcwings with a pointed apex, and cyctops. 

 rounded hindwings jorotracted in the middle of the margin, with a slightly lobatc anal part. All the wings are 

 black, tinted reddish; at the apex lighter, traversed by dark bands. In the forewing before the apex a cuived 

 ]-ow of black dot.s from the costa to the middle of the wing, where it often disappears, at the casta centred 

 white and behind exhibiting a whitish macula, and also above the dot very finely jnipillcd white. 



A. colotes G. (£• *S'. (ITIJa). This species established according to but 2 Q''^^ entirely resembles siuiplc.i- roUitcs. 

 (175 h, i) above, but beneath it is very different : greyish-brown, on the hindwing and in the antemarginal area 

 of the forewing lighter; the hindwing exhibits at the cell-end a band-shaped, dark spot and behind it a 

 slightly bent, somewhat longer band, the base and margin being likewise darkened. Nicaragua and Panama. 



A. oiclus Mab. is dark red-brown, the forewing with 2 broad, straight bands touching the proximal oiclus. 

 margin in a right angle, and with 3 small subapical dots; hindwing with a rounded spot at the base, behind 

 it a semicircular band. Beneath lighter brown, the hindwing in the anal half of the distal margin yellow into 

 which colour a piece of the black postdiscal band extends. Panama (C'hiriqui). 



A. orsus 3Iab. This species is unknown to me and its appertaining to this genus is questionable, orsu.s. 

 Above reddish-brown, with 3 small subapical dots and 2 broad, black, faded bands suffused with violet; the 

 hindwing shows a similar cell-spot and a curved median band, the margin being darkened, too. Beneath lustrous 

 lilac-grey, hindwing with 2 curved bands, one postdiscal and one antemarginal band, which terminate before 

 the proximal margin. From Porto Cabejlo. 



28. Genus: Pachyiieiiria Mnb. 



A very peculiar genus deviating by the doubly bent, very strong costal-marginal vein excelling the 

 subcostal vein in thickness, and by the remarkably strong submedian fold. Distal margin nearly just as long 

 as the proximal margin; on the forewing the middle radial vein is much nearer to the upper one than to the 

 lower. Terminal joint of the palpi conical, rather long, set straight forward. Antennae with a long club and 

 a fine, bent apex. Posterior tibiae fringed with 2 pair of spurs. 



P. obscura Mab. (17(5 a) is lustrous olive-grey with thick, black veins and a dentate antemarginal obscura. 

 line. Beneath dull black. Colombia, Peru, Bolivia. 



29. Genus: Praxis Mab. 



The only species known is a small insect with horizontally porrect palpi. Antennae with a fusiform 

 club, bent round in the second third. Distal margin of forewing below the lower median vein with a concavity 

 so that above it a small angle arises. Hindwing somewhat angled. Posterior tibiae with long, fluffy hair and 

 2 pair of short spurs. 



P. quadrata Mab. is dark brown with a black basal stripe and a large, oblicpiely quadrangular spot quadrata. 

 in the disc, one point of which touches the costal margin; apex likewise darkened. HindAving with 2 shortened 

 bands from the costal margin. Beneath reddish-brown, at the proximal margin of the forewing whitish. Described 

 according to 1 ^J from Massauary. 



30. Genus: i^ostrata G. d- S. 



The antennal club is longer than in the preceding genus, the 3rd palpal joint likewise longer. Forewing 

 longer and narrower with a rounded distal margin and costal fold. Posterior tibiae with 2 pau' of spurs. On 

 the whole not dissimilar to the sjDecies of Paches and to some blue Pijthonides. 



S. scintillans Mab. (176 a) is blackish, towards the margin with a lilac reflection, strewn with numerous schifiJIons 

 silvery-blue, small scale-spots, and some narrow-, black undulate bands, some postmedian, rather inconspicuous, 

 small hyaline spots. Beneath lighter brown with darker, undulate transverse lines. Mexico to Brazil. 



?»as. 



S. adatnas H.-Schaff. (= leucorrhoa G. d- *S'.) (17Ca) is above the same, but beneath the anal part ada 

 of the hindwing is bluish-white; also on the forewing the proximal margin is spotted white. From Panama 

 to Colombia. 



S. pusilla 6-'. ci- »S'. (176 a) is considerably smaller, of a purer black and only towards the base puaiUa. 

 strewn with silvery blue; the subapical dots of the forewings are absent. Nicaragua; Panama; Amazon. 



S. plumbago Plotz (= chalybs Mab.) (176 a) is brown with a broad, black transverse band strewn pltinibaijo. 

 with silvery blue. Beneath lighter brown with a yellowish base and proximal margin, the hindwing suffused 

 with a lustrous grey, with a black macular band, in the middle double. From Peru (Chanchamayo).
