ANTIRRHAEA. By G. Weymeh. I79 



hind wing is much larger, nearly round, 10 — I'd mm. in diameter, and extemls nearly to the costal margin. 



At the inner margin of the hindwing there is in the ^^ a patch of light ochre-yellow, appressed scale.s 



10 — 12 mm. in length. Under surface yellowish grey, on the forewing with -2 brown lines, contiguous in 



the middle and diverging anteriorly and posteriorly, and with a short ul)liiiue line in the cell, and 3 black 



dots near it. On the hindwing there are 3 black dots basally to the 3 almost .straight parallel transverse 



lines and before the distal margin a row of 5 similar dots. Amazons and Ecuador. — hortensia Flclr. is a horlcnsia. 



local form which is distinguished by narrower wings, smaller blue spots on the forewing and less rounded 



sjiots on the hindwing, which are placed further from the distal margin. From the Eio Xegro. 



4. Genus: Aiitirrhsiea Hbn. 



Medium-sized and large iiutterflies of 65 — lUo mm. in expanse, mostly dark-coloured, only a few- 

 having blue, white or red-yellow markings. The palpi are densely covered with stiff hairs, the antennae 

 tlun, thickened towards the end, without distinct club. In most species the veins of the forewing are not 

 swollen, onh' in archaea the costal vein is somewhat thickened and in hela distinctly swollen. In the hind- 

 wing the costal vein does not arise direct from the base, as in the preceding genera, but on a common 

 short stalk with the subcostal. The precostal also arises at the point of separation of these veins. This 

 is likewise the case in all the following genera of Satyrids. The principal distinguishing character of Aniir- 

 rhaea consists in the scent-organ of the (^(^, a brush of hairs on the underside of the forewing between 

 median and submedian. This differs in size, shape and position in the indi\idual species, being mostly liasally 

 pointed, anteriorly and distally rounded. The hairs are glossy, 3 — 4 mm. long and have th(^ ti]'s bent 

 towards one another. In most species the scent-organ stands out before the costal margin of the hindwing, 

 in single cases, e. g. in gfer!/on, it even remains liidden if the forewing is much brought forward in setting. In 

 consequence of this brush cellule 1 b is very broad between median and submedian, up to 12 mm., and 

 the submedian and inner margin are semicircularly curved posteriorly. In the female the scent-organ is 

 absent and the submedian and inner margin of the forewing are straight. The genus is distributed from 

 Guatemala to South Brazil through Central and South America. 



a) 111 the ,:JcJ the subcostal and upper radial of the hindwing arise near together but separate out of 

 the anterior margin of the cell, converge somewhat for a short distance and then diverge strongly. Hence the 

 upper discocellular is short and only reaches '/« to ','* the length of the middle discoceUuIar. The inner margin 

 of the forewing in the 3S deviates 2 — 1mm. from the rectilinear. In the ?? subcostal and upper radial diverge 

 from the point of origin. Apex of the forewing rounded. Hindwing with obtuse angle at the middle or upper 

 median (AnchijMebia Btlr.). 



A. archaea Hhn. (= girondius Godt.) (43 d). The genus Antirrhaea was founded on this species. The $ nrchcwn. 

 is very similar to the figured (J," except that it has the inner margin of the forewing straight. On the under surface, 

 which is striated with yellow-brown and white-streaked, there are only small white dots instead of the eye- 

 spots. The scent-apparatus of the (J^J consists of a semicircle of yellow-brown, dense hair, 3 — 4 mm. long, placed 

 close above the submedian, the hairs directed anteriorly and w^ith the points bent towards one another. 

 The length of this brush is 10—11 mm. Opposite to the scent-organ on the upper.side of the fore%ving 

 there is an oval spot of flattened scales, which is the same colour as the ground, and hence may easily be 

 overlooked. According to WiLii. JIulleb, who has obtained the young larva from the egg, but was not 

 able to rear it, as it would not touch the grasses, etc., placed before it, the egg is semicircular, the surface 

 divided by raised ridges into regular, hexagonal areas. The body of the larva when first hatched is 

 3.8 mm. long, the tail-fork with the terminal bristle 2.7 mm., thus proportionately very long. Head large, 

 black, rugose, covered with bristles, above with a bipartite process. Body thinner than the head, white 

 with red-brown prothorax and brownish or reddish dorsal and lateral lines. The tail-fork is black. A\idely 

 distributed in Brazil: Bahia, Espirito Santo, Santa Catharina, Rio Janeiro. 



A. taygetina Btlr. Similar to the preceding species, but somewhat smaller, with only 2 smaller lamnihia. 

 ocelli on the forewing, whose pupils are shifted distad and wliich are placed in the ochre-yellow band. 

 Sometimes there is further a third very small ocellus at the costal margin. Ground-colour brown-grey; 

 hindwing in the distal half dark brown "with 2 to 4 light blue or light violet spots. Beneath light ochre- 

 yellow, sometimes rose-reddish with 2 brown median lines, diverging at the costa of the forewing, of 

 which the outer one i--. distally margined with white, with an indistinct, undulate, brown submarginal line 

 and 5 white dots on both wings in an angular row. From Massauary, Teffe, Coary and Pebas on the 

 Amazon. Rare. 



A. hela Fldr. (43 b). Upper surface dark brown. The forewing has before the apex 2 white spots hda. 

 with blue rings and in the posterior half of the wing 3 blue spots, of which the first 2 have white pupils. 

 All 5 spots are placed in a row. In the neighbourhood of these spots the dark brown ground-colour has a 

 blue reflection. Hindwing without markings. The under surface is grey-brown, finely striated with dark
