270 JOSIODES. By Dr. M. Drattdt. 
a costal-marginal fold covered with hair, and near the base below the cell a prominent scent-spot. Cell of the 
hindwing very short; the lower radial vein anastomoses with the upper median vein; the middle one is absent, 
the upper one anastomoses with the subcostal; on both sides of the costal-marginal vein thick, rough scales. 
The margin of the hindwing is broadly excised below the apex. Only 1 species: 
E. speciosa Schs. (35 g). Body blackish-brown, with a yellow anal tuft, venter grey. Forewings light 
brown, thickly dusted blackish-brown, below the costal margin the darkest. Hindwings blackish-brown, in 
the costal-marginal area lighter, apex black. The scent-scales of the under surface are ochreous-yellow. Expanse 
of wings: 16 mm. French Guiana. 
56. Genus: •fosiodes Fldr. 
One of the more numerous genera, containing mostly bright orange species marked with black, often 
exhibiting similarities with Arctiids and Geometrids. Proboscis developed; the short palpi are porrect; antennae 
of the provided with bristles and cilia. Posterior tarsi with moderately long spurs. On the mostly long and 
rather narrow forewing the upper median vein rises before the cell-angle, the middle radial vein above it, the 
upper one below the upper angle; the two upper subcostal veins come from the cell and terminate into the 
costal margin, the 3 lower ones on a common pedicle. Cell of the hindwing long, the upper median vein likewise 
rising before the cell-angle; the two lower radial veins rise from it, the upper one is petioled with the subcostal 
vein. The species fly in day-time and at night. 
J. myrrha Cr. (— fulvia Clerck) (35 d) is of a bright orange on its body and wings; palpi, forehead, 
antennae, legs, and a dorsal stripe on the abdomen bluish-black. On the forewing the costal margin and 
distal margin, as well as a subapical oblique band are black, like on the hindwing the distal margin which is 
somewhat narrowed near the median veins. Expanse of wings: 34 mm. Surinam. 
J. suapurensis Rothsch. (35 d) resembles myrrha, the black colour on the wings much more extensive, 
the black marginal band of the hindwing projects to the cell and below the submedian fold inwards, at the 
latter almost to the base. The abdomen is almost entirely black, only at the base laterally somewhat orange. 
In the much larger $ the black colour is more reduced, particularly on the hindwing. Epanse of wings: 32 mm, 
$ 38 mm. Venezuela. 
J. intensa Rothsch. (35 e), described according to a §, greatly resembles the $ of the preceding, 
though it is larger, the border of the wings more uniform. Expanse of wings: 40 mm. Surinam. 
J. nigrobasalis Rothsch. (35 e). Head and thorax quite black, also the abdomen, which exhibits some 
orange only on the sides. Forewing at the base black, only the cell remains orange as far as the base. Hindwing 
in the $ quite black, only the proximal margin and a small spot behind the cell orange. The A has orange hind- 
wings with a black border, less black at the base of the forewing, and the orange oblique band in the apex is 
absent altogether. Expanse of Avings: $ 34 mm, $ 46 mm. British Guiana. 
J. indecisa Btlr. (35 d) is similar to the preceding, but the costal margin of the forewing is only 
in the basal third subcostally black, the proximal margin is broader black, and in the submedian space there 
is in the middle above it another black stripe. Hindwings very broadly margined with black. The body is 
entirely black, only on the collar spotted orange, and on the abdomen with narrow lateral stripes. In decisa 
form. nov. the proximal margin is much narrower black and the stripe above it is absent. Expanse of wings: 
40 mm. Amazon. 
J. toxaridia Drc. (35 d) likervise resembles the two preceding species, differing, however, by the 
body being all black with only orange-yellow shoulder-covers and abdominal stripes. Expanse of wings: 
36 mm. Ecuador. 
J. repleta Wkr. (= abscissa Hbn. p.p.) (35 d) is black on its head, thorax and abdomen, anteriorly 
Avith a blue reflection; sides and venter are orange except the 2 last rings. Forewings orange, costal and proximal 
margins black, like the apex and a subapical spot. Hindwings orange with a black costal margin and distal 
margin, with an irregularly dentate, proximal border not reaching the proximal angle. The $ exhibits a broader, 
subapical oblique band. — In striata form. nov. (= ab. 1 Hmps.) there occur black stripes on the hindAving 
in and below the cell, being confluent towards the base. The shoulder-covers sometimes exhibit small orange 
spots , the venter is occasionally quite black or banded black. Expanse of wings: $ 36 mm, $ 44 mm. Amazon. 
J. immutata Wkr. (36 d) is most easily discernible from the preceding by a large, triangular, black 
inner-marginal spot of the hindwing, the distal margin being expanded. The body is bluish-black, on the shoulder- 
covers and sides of abdomen orange. Expanse of wings: 40 mm. Brazil. 
J. fallax Btlr. (35 d) closely resembles immutata from which it differs by its broad black proximal 
margin and proximal angle, the subapical band being uniformly curved; on the hindwing the black is still broader. 
In the $ the orange lateral stripes on the abdomen broader. Expanse of wings: A 36 mm, $ 42 mm. Brazil. 
J. tenuifascia Hmps. (35 e) is smaller, the orange colour on the forewing confined to a narrow median 
stripe, the subapical spot small and irregular. Expanse of wings: 30 to 32 mm. Brazil. 
J. peruviana Schs. Body like in the preceding. On the forewing the narrow, orange longitudinal band 
extends from the base to the transverse vein, then it bends round along the lower median vein almost as far as 
the border; the subapical spot is curved, almost transverse. On the hindwing a narroAv, orange band beloAv
