DISMOEPHIA. By J, Boher. 103 



margin itself is very narrowly brown-red and the hindwing only differs from that of arsinoe by the red-brown , 



inner margin. — arsinoides Stgr., from Chiriqui, has the hindwing as in astynomides, but the yellow spots arsinoides.'^'^' 

 of the central row are smaller and widely separated and the inner margin of the forewing is broadly black. 



— praxinoe Dhh, from Mexico, differs from arsinoides in that the white scent-scale-area of the hindwing throws praxinoe. uTi? '^ 

 ; out some teeth into the black distal margin and the colour of the red-brown markings is hghter. — discrepans discrcpcms. 4^5 



v Btlr. (30 c), from Colombia and Ecuador, has only very small yellow spots instead of the yellow median band. 



— meridionalis /orm.. nov., from Bolivia, has only two yellow subapical spots on the forewing and a yellow meridionalis ^c y 

 median band, interrupted in the middle but broad, which does not touch the reduced red-brown markings. 



— amphithea Fldr., from Mexico, is larger than arnphioyie and has larger and broader, more falcate forewing. amphit}ieaAZ^ 

 Unknown to me, probably not different from 'praxinoe. — egaena Bates, from Ega, is in the female very dark egaena. c-^$^ 

 red-brown, has much yellow central and subapical marking and is very similar to Mechanitis polymnia egaensis iz >/ 

 Bates. ^ — rhomboidea Btlr., from Nanta (probably East Peru) (or Nauta, Upper Amazon?), is the largest rhomboideaJ'i/ 

 form. In it the yellow subapical spots are entirely absent, the red-brown markings are much developed and 



in the posterior part of the forewing reach the distal margin, the yellow median band is only represented 

 by some small spots at the costal margin. The $ has red-brown hindwing with black wedge-shaped marginal 

 spots, the yellow median band is very broad and almost reaches the inner angle. Is perhaps a separate species. 

 Only known to me from the figure. 

 -^ D. laia G^&6fe."^Shape and size as amphione. Forewing black with 3 red-brown spots: a long one in lain./ 



^ the cell, another at the inner margin, and the third, a small round one, is placed towards the middle of the " 



wing and sometimes united with the first; in addition the distal half of the wing is distinguished by a band- 

 like spot, divided by the veins. Upper surface of the hindwing broadly glossy white along the costal 

 margin, then red-brown with black, dentate, rather broad margin. Under surface of the forewing glossy 

 white, margined with yellow at the apex, the other markings as above, but larger, under surface of the hind- 

 wing brownish with several lighter patches, the apex margined with red, a row of rather large yellow marginal 

 spots and 2 small spots of the same colour near the distal margin (at the distal angle). Surinam, Cayenne. 

 Only known to me from the description. 



D. astynome Dalm. (= polymela Hhn.) (30 c), from Brazil (Santa Catharina), is very similar to ampliione, astynomi 



but most probably a separate species. Instead of a row of yellow subapical spots astynome has only one such _ i f l'-^ xl 

 spot, occasionally with a dot before it, and this is placed nearer to the apex than the row of spots in ampliione.' ' #*^ 



The inner margin of the forewing is always broadly black. The under surface is essentially different.; — astyocha asiyocha. - r" 

 Hbn., from Bio Grande do Sul and Sao Paulo, differs in the yellow apical spot of the forewing being placed s^ Q l- cLaixA (2- 

 directly at the margin and the under surface being lighter and less marked. ,' '^ ■ .. 



"^ D. dejone Hew. (30 c), from Central America, has the forewing black above with white spots, the anterior dejone. ^^ \ 



half of the hindwing (scent-spot) light grey, shiny, posterior part of the hindwing red-brown with black margin. ' 



Under surface of the hindwing grey-brown with a transverse row of yellow spots in the middle and a few 

 other vellow spots and dots. 2 unknown to me. 



/ D. sororna Btlr. (30 d), from Costa Rica and Chiriqui, is a large species. The (^ has black forewing sororna. ■' y-' 



with yellowish apical, subapical and central spots, the larger anterior part of the hindwing (scent-spot) is light ! 



grey, with silky gloss, the posterior part is red-brown, margined with black. The $ resembles the Lycorea- \^ 



.species; it has black forewing with the same rows of spots as the ^, in addition a red-brown transverse band 

 on the proximal half of the forewing, the hindwing is red-brown with black distal margin and some small , 



yellow marginal spots. The under surface resembles the upper. — hagaresa Btlr., from Costa Rica, is pro- hagaresa.f' >- 

 bably nothing more than a less marked form of sororna (seasonal form?). ' — 



•D. Cordillera Fldr. (30 d), from Colombia and Chiriqui, though specifically separated by Butleb from cordillera. '*•" 

 sororna, appears really to belong to it as a seasonal form. The yellow spots of the forewing are larger, in the (J 

 the posterior part of the hindwing is yellow and the $ also has lighter markings, hence the hindwing is 

 almost yellow. The under surface resembles the upper in markings and colouring. 



D. orise Bdv. (30 e), from Guiana and Bolivia, but probably also occurring elsewhere, is very similar orise. f^ < 

 to Thyridia psidii L. and confusa Btlr., especially in the female. The perfectly transparent wings have black ^ 



margin and black median band, which, however, in the J only reaches the middle of the wing on account of 

 the scent-scale on the anterior half of the hindwing. j«^ J>( 



D. rhetes Rew., from Colombia, differs from hewitsoni Kirhy (30 e, f), from Ecuador, only in the Hght ^hewitsoni 

 spots on the distal part of the forewing and on the hindwing being white (glassy), not bluish. This species 

 bears a general resemblance to several of the larger Ithomiids. 



D. theonoe Hew. (30 e), from Eeuaior, is very similar to Ithomia flora Cr. It is transparent and has theonoe. / - ^ 

 t)lack margins and markings. — melanoe Bates, from the Upper Amazon, has broader black margins and bands; melanoe.'i'/ 

 it is regarded by Bates as a mimic of Ithomia onega Hew. J ^ 



D. siloe Hew. (30 e), from Colombia, has the posterior half of the hindwing red-brown. It has the general siloe. ji^ i 

 aspect of an Ithomiid, but is not specially like any particular species. '■.X'
