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



— ■ meridionalis form, nor., from Bolivia, has only twt) yellow suliapical spots on the forewing and a xvWow incridionalis 

 methan band, interi'upted in the middle but br(jad, which does not touch the reduced red-in-own markings.

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



in the posterior part of the forewing reach the distal margin, the yellow median Ijand is only lepresented 



ijy some small spots at the custal margin. The ',.' has red-brown hindwing with black wedge-shaped marginal 



spots, the yellow median band is very broad and almost ii'aches the inner angli'. Is ]>erhaps a sepai-ate species. 



Only known to me from the figure. 



D. laia (/odt. Shape and size as aiHiiJiionc. Forewing black with 3 jcd-biown spots: a long one in hiia. 

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

 wing and sometimes united with the first; in addition the distal half of the wing is distinguished Ijy 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 glossj' 

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

 wing In'ownish with several lighter patches, the apex margined with red. a row of rather lai'ge yellow marginal 

 spots and 2 small spots of the same colour near the distal mai'gin (at tiu-" distal angle). Surinam. Cayenne. 

 Only known to me from the descrijition. 



D. astynome Dalm. (= polymela Hbn.) (30c), from Brazil (Santa C'atharina), is veij similar to avipJilone, (isIjihoukj. 

 but most probably a separate species. Instead of a row of yellow subapical spots astynome has only one such 

 spot, occasionally with a dot before it, and this is placed nearer to the apex than the row of spots in amplilone. 

 The inner margin of the forewing is always broadly black. The under surface is essentially different. — astyoclia uslynchci. 

 Hbn., from Rio Grande do Sul and Sao Paulo, differs in the yellow apical spot of the foi-ewing being placed 

 directly at the margin and the under surface being lighter and less marked. 



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

 luilf 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 tlie middle and a few 

 other yellow spots and dots. $ unknown to me. 



D. SOrorna Bth-. (30 d), from Costa, liica and Chiri(iui, is a large sjiecies. The j" has black forewing aororna. 

 with yellowish apical, subapical ami 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 l>lack forewing with the same rows of spots as the (^, in addition a red-browii transverse liand 

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

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

 baldy notlhng more than a less maiked furm (if sororna (seasonal form"?). 



D. Cordillera Fldr. (30 d), from Colombia and Chiriqui, though specifically separated by Butler from cordiUera. 

 sororna, appears really to belong to it as a seasonal form. The yellow spots of the forewing are larger, in the (5" 

 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 or/.vt>. 

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

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

 the scent-scale on the anterior half of the hindwing. 



D. rhetes Hew., from Colombia, differs from hewitsoni Kirhy (30 e, f). from Ecuador, only in the light h'm-Usoni 

 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 Itliomiids. 



D. theonoe Hew. (30 e), from Ecuador, is very .similar to Ithomiu flora Cr. It is transparent and has Iheonoe. 

 lilack margins and markings. — melanoe Bates, from the Upper Amazon, has broader black margins and bands; melanoe. 

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



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

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