.s;/,,;>/Ki«.s;- M. simplicissimus H.-ScMff. (= nigritulus 3Iab., insignis Pl&z. facilis Ploiz) (187 k) is the same, but 



'""■•'■• without a stigma, with shorter palpi beneath mixed with golden yellow. Fringes dark grey. South America, 

 widely distributed as far as Trinidad. 

 hirida. M. lufida H.-Schiiff. (187 g). Above monotonously blackish-brown. Beneath the costal-marginal 



part of the forewing is somewhat reddish, the distal margin of both wings is brightened up by a somewhat duller 

 brown. Basal part and disc of the hindwing dark red-bro^\ Ji, at the co.stal margin extended to the apex. Described 

 from Brazil. 

 chn/s(iiiliri/s. M. chrysophrys Mab. is likewise very closelj- allied, but it has somewhat longer antennae, bright yellow 



fringes, and an indistinct, bipartite stigma. Expanse of wings: 21 mm. Colombia. 



149. Genus: lliiasalcns G. d: S. 



Antennae of ^/g the length of the costal margin, club stout with a long apex. The ^ shows a tripartite 

 stigma: a scent-stripe on the median between both veins, a short one below it, and a triangular part in the 

 middle of the submedian. 

 iiiiifoniiis. M. uniforniis Btlr. Monotonously blackish-biown, beneath somewhat biowner, with a lighter proxi- 



mal margin of the forewing. Palpi haired blackish-brown. Costa Rica; Tiinidad. 

 iniuitiila. M. amatala 8chs. Above dark brown, also at the base of the hindwing with an oblique scent-scale 



spot. Beneath likewise brown. Costal margin of forewing for two thiids, cell and basal lialf of the pioxin:al 

 margin darker, distally to it a row of indistinct, lighter spots. Hindwing dark violettish-brc^vn in the basal 

 2 thirds, with some small postdiscal. indistinct, light spots. Expanse of wings: 31 mm. Novo Friburgo. 



circiUiita. M. circellata Plotz (187 h) according to the figure by the shajoe of the scent-organ belongs hereto and 



is perhaps to be combined with amatala. Above blackish-brown, fringes somewhat ochreous-brownish. Beneath 

 browner, basally darkened, on the fore- and hindwings with some small, postdiscal, light indistinct spots, the 

 hmdwing also shows a cellular dot. Brazil. 



150. Genus : Maxtor G. (fc 8. 



Antennae half as long as the costal margin. Costal margin of foiewing at the base convex. Middle 

 tibiae spined. The (J has an oblique scent-stripe from the rise of the upper median vein to the middle of the 

 submedian (the stigma is absent in M. perigenes). 



amibia. M. anubis G. <£■ S. (= perloides Plotz) (187 g). Blackish-brown with a stigma of the same colour; 



beneath the same, palpi intermixed with golden yellow hair; the base of the antennal club beiieath and distally 

 ochreous-yellow; sometimes there is on the hindwing beneath a postdiscal row of ochreous-yellow dots. Mexico. 



bcllii.'i. M. bellus Edw. (187 h) is easily discernible by the ochreous-yellow fringes of the wings. Arizona, 



plii/lace. Mexico in May. — phylace Edw. (187 g), according to recent reports, seems to be a second stock of hellus. It 



differs by the head and collar being golden yellow, the fringes, however, dirty grey. In this case phylace (187 h) 



would have to be the name of the species, and hellus its first form of generation. From Colorado, Arizona and 



New Mexico in July. 



pcrhi. M. peria Plotz (187 g) is larger, above blackish-brown, with ash-grey fringes and similar hairing of 



the body. Beneath on the forewing somewhat lighter, the hindwing ash-coloured, with fine darker veins, a 

 whitish cellular spot and 4 small postdiscal dots in the apical half. Rio de Janeiro. 



perUjciieH. M. pcrigcnes G. «£• (S*. (187 g) is easily recognizable by the absence of the stigma and the hindwing 



beneath being peculiarly radiantly striped brownish and whitish. Mexico. 



151. Genus: MuasiluK G. <& S. 



Distinguished from the allied genera by a hair-pencil on the forewing above below the submedian. 

 Middle tibiae spined; stigma absent. 



penicilUiiiis. Mn. penicillatus G. & S. (= zalma Plotz) (187 h) somewhat resembles above Metrort chrysogaster 



(187 d), but the ochreous spots form a complete oblique row as far as below the apex. Beneath somewhat lighter; 

 hindwing with 5 lighter dots in a bent row. Mexico to the Amazon and Brazil. 



auan-a. Mn. sucova ScJis. has the hau--pencil below the base of the median and may therefore be best inserted 



here. Above blackish-brown, fringes lighter, forewing with a somewhat darker shade at the cell-end. Beneath 

 the forewing is blackish at the base, violettish-brown at the apex and costal margin; a small Avhitish hair-,- pot 

 behind the lower cell-end. Hindwing violettish-brown with a bent row of small grey diffuse patches behind 

 the cell. Expanse of wings: 29 mm. Petropolis.
