Pi,bl. 19. IV. 19-21. AMENIS; MYSORIA; YANGUNA. By Dr. M. Draudt. 841 



J. fleximargo Mah. & Boull. is distinguished by its entirely black hindhead; the marginal band fleximargo. 

 of the hindwing is broader between the median and radial veins than the fringes are, on both sides of them, 

 however, narrower; the fringes of the forewing are blackened towards the apex. Bolivia. 



2. Genus: Ameiiis Wts. 



The genus contains animals greatly resembling the preceding in their exterior, chiefly distinguished 

 by the bare posterior tibiae, the wings being generally narrower and the apex of the forewing somewhat prolonged. 



A. piotlia Hew. (162 h) is black with a deep blue metallic reflection, at the anal angle of the hindwing [noma. 

 silvery blue, prominent spots ; in the middle of the forewing there are two red spots below each other. On the 

 under surface particularly the hindwings are blue-white towards the base, the fringes of all the 4 wings are 

 of a pure white; the distal margin of the hindwing is concave in the (J, the anal angle extended in the shape 

 of a lobe. Colombia. 



A. ponina H.-Schdff. is extremely similar, but it has dirty yellow, instead of white fringes, and those ponma. 

 of the hindwings are much longer. Panama. 



A. affinis H.-Schdff. (162 h). Above deep bluish black with white fringes, a carmine ring at the neck, affinis. 

 palpal base and abdominal end ; the sides of the abdomen are striped yellow, the costal margin of the hindwing 

 beneath is narrowly orange-yellow, which colour extends as a fine marginal line before the fringes as far as near 

 the anal angle. Colombia, Brazil, also in numbers from West Mexico (Guerrero). 



A. amra Hew. (= brasiliensis Mah.) (166 c) differs from the preceding by red-striped abdominal sides amra. 

 and by the yellow marginal band of the hindwing beneath being broader than the fringes. Brazil. 



A. proxima Mab. & Boull. has red-spotted abdominal sides and a red costal margin of the hindwing proxima. 

 beneath; the marginal band before the fringes on the hindwing is of the double width of the fringes. The species 

 is besides by one third larger than amra. Distributed from Mexico through Colombia as far as Paraguay. 



A. ambigua Mab. <& Boull. exactly resembles Mysoria venezuelae (162 h) and is only discernible ambigua. 

 by the veins. It has the broadest marginal band of the hindwing, which is more than twice as broad as the 

 fringes. Brazil.

3. Genus: Mysoria Wts. 



Entirely like the preceding genus in the structure except the petiolation of the upper median and lower 

 radial vein of the hindwing, rising from above the lower cell-angle; the posterior tibiae are likewise bare. 



M. sejanus Hpffr. (162 g) is above dull bluish-black with a red abdominal end; hindhead, collar sejamui. 

 and first joint of the palpus are black. Beneath the costal margin of the hindwing is not differently coloixred. 

 Bolivia. 



M. thasus Cr. (162 h) is just the same but it has a red spot on the hindhead and on the middle of thasus. 

 the collar, and a red first palpal joint. Colombia and Peru. 



M. pallens 3Iab. is similar, but it has beneath in front of the white fringes of the hindwing a yellow paUem. 

 marginal band. From BrazU. 



M. decolor Mab. & Boull. differs from the preceding hy the white marginal band of the hindwing decolor. 

 being strewn black, instead of the yellow one, exhibiting traces of a red costal margin of the hindwing. Costa 

 Rica and Panama. 



M. venezuelae Scudd. (= acastus auct. nee Cr.) (162 h) has on the under surface a red costal margin venezuelae. 

 of the hindwing, which grows a little broader towards the base, and a yellow marginal band before the white 

 fringes, which gradually grows narrower towards the anal angle. The fringes of the forewing are of a pure white 

 as far as the apex. Distributed from Mexico to Colombia. 



M. cayennae Mab. & Boull. differs from the preceding species by the fringes of the forewing being cayennae. 

 blackened from the upper median vein to the apex, and besides the red costal margin of the hindwing beneath 

 is equally broad as far as the base. — In the form verbena Btlr. (= phidias F., barcastus Sepp) the otherwise verbena. 

 yellow marginal band of the hindwing is red, like in: acastus Cr. in which form the red at the costal margin acastus. 

 of the hindwing is extinct. Guiana. 



4. Genus: Yaiiguiia Wts. 



This genus contains large, very strong animals. On the forewing the upper median vein rises far behind 

 the middle of the cell, both the lower subcostal veins rising separately ; on the hindwing the cell is longer than
