842 MAHOTLS. By Dr. M, Draudt. 



half the costal margin, the middle radial is absent ; the distal margin is feebly undulate or somewhat concave. 

 The posterior tibiae show 2 pair of spurs. 



spatiosa. Y. spatiosa He^v. (164 b) is a large beautiful species, black with a deep hemochrome base of the 



forewing and a larger discal spot of the hindwing, also the thorax and base of abdomen are intermixed with 

 red hair. The forewing exhibits a broad tripartite band of vitreous spots in the middle and 2 shorter and narrower 

 ones behind it, often between the second and third besides 2 minute vitreous spots; the under surface is dull 

 lustrous indigo-blue with a red diffuse spot at the base of the hindwing. Ecuador, Colombia. 



cosyra. Y. cosyra Dree. (164 b) differs from the preceding by yellow-red and less extensive basal spots; the 



2 hyaline dots between the apical and postdiscal bands are always absent ; the abdomen is more conspicuously 

 curled whitish. Bolivia and Peru. 



staudbigeri. Y. staudingeri Plotz (164 b) is likewise very similar, but it has only 2 small hyaline spots, the discal 



one of which is shorter and broader ; the basal spots are of a pui'er red, the under surface of a brighter metallic 



cometides. blue. In the form: — cometides Stgr. (164 b) the apical hyaline spots are also absent, so that there only remains 



the large discal hyaline spot, and besides the red colom: is mostly more or less confined and may be entirely 



absent on the wings. From Peru and Bolivia. 



aspilos. Y, aspilos 3Iab. <&; Boull. (164 b) is without any hyaline spots, it is entirely bluish-black with 



yellow-red basal spots. Peru, Bolivia. 



comeies. Y. coiiietes Cr. (= thelersa Hew.) resembles .staudingeri (164 b) above and has also only 2 rows of 



hyaline spots, the insignificant basal spots are rusty-red. Beneath distinguishable by its reddish ground-colour 

 with black marginal spots on the hindwings, 2 or 3 of which at the proximal angle are pupilled white. Surinam. 



aspitha. Y. aspitha Hew. (164 c) is very much like comete,s, but it has only one small apical hyaline spot 



and yellow-red basal spots; the abdomen is curled white like in cosyra. Para. 



ruhricollis. Y. rubricollis Sepp (164 c) has on the black wings only one tripartite hyaline discal spot, a black 



head and abdomen and red-spotted shoulders. Surinam. 



pedaia. Y. pedaia Heiv. (164 c) differs from rubricollis by its red head and apex of abdomen, whereas the 



shoulders remain black. Amazon. 



hadora. Y. hadora Hew. (164 c) is the same, but it has a black abdominal apex, a red prothorax, and on 



the red head a black transverse streak between the eyes. Ega. 



arinas. Y. arinas Cr. (^ arinus F.) (164 c) has a more intense blue lustre on the wings, with a more 



rounded oval, hyaline discal spot; only the frons and apex of abdomen are black. Fringes of the hindwings 

 white. Surinam. 



assaricus. Y. assaricus Cr. (= alsarius F.) (164c) is a smaller, somewhat more variegated species; beside 



the white discal band of the forewing it has 3 apical hyaline spots and 3 before them, with a red-spotted base; 

 base and disc of the hindwing are red-brown with 2 black spots in it near the proximal margin; the fringes of 

 the hindwing are speckled white. On the under surface the hindwings are spotted blue and white. The abdomen 

 is red and black, whith whitish rings and a red end; the head is black. Guiana. 



parima. Y. parima Plotz (164 d) is likewise smaller and neater with a very concave excision of the distal 



margin of the hindwing. The black forewing exhibits beside the orange-red discal band two rows of hyaline 

 spots, the hindwing a large red anal-angular spot. Thorax and head likewise red-yellow. Surinam to Bolivia. 



5. Genus: lEahotis Wts. 



Closely allied to the preceding genus, but it has only terminal spurs on the posterior tibiae, and the 

 cell of the hindwing is shorter and does not reach the middle of the wing, the distal margin of the hindwing 

 is entire and round ; the upper median and lower radial vein rise together from the lower cell-angle or also short- 

 petioled. 



crida. M. Cfida Dhl. (164 e) may not belong here at all. The wings are black with a discal spot; head and 



apex of abdomen red. Nicaragua. 



nurscia. M. nurscia Sums. (164 d) is above black with a large, brick-reddish, somewhat transparent discal 



spot, the hindwings have some blue macular markings particularly towards the distal margin. Beneath the 

 hindwings are blue with a black marginal band and 2 black basal rays. Ecuador and Peru. 



ynalis. M. malis G. <fc S. (164 d) is above very similar, but beneath quite different, the hindwings being 



black with 3 blue transverse bands, the middle one of which consists of separate spots. Colombia.
