ISOSTOLA; JOSIOMORPHOIDES; SAGAROPSIS. By Dr. M. Hering. 
12. Genus: Isostola Fldr. 
Veins agreeing with those of Ephestris, but the 1st and 2nd cubitus of the forewing run parallel or 
diverge towards the margin. All the species are black, with a lustrous blue colour, with whitish hyaline markings. 
They resemble certain Syntomiclae ( Agyrta , Cyanopepla , t. 24), Dioptidae (.Phanoptis ) or Geometridae ( Gonora ). 
divisa. I. divisa Wkr. (61 c). The hyaline spot before the centre of the forewing behind the cell does not 
extend to the base, the hyaline central spot of the hindwing is the broadest before the centre of the wing; — 
vicina. in the form vicina Btlr. the postcellular spot of the forewing extends to the base of the wing, the central 
spot of the hindwing is the broadest in or behind the centre. From Venezuela to South Brazil and Peru. 
flavicollaris. I. flavicollaris sp. n. resembles the preceding, but on the collar there are instead of the white dots 
two yellow spots. The discal band of the forewing is longer, more uniformly broad, in front not pointed. Panama, 
o type from Chiriqui in the Berlin Museum. 
dilatata. I. dilatata sp. n. Wings on the whole broader than in divisa (61 c). The discal band of the forewing 
is very broad, occupying yet a part of the discal cell, at the proximal margin somewhat narrower. Collar with 
two white dots, basal joint of the palpi and prothorax like in divisa below red (in flavicollaris yellow). In this 
species and the following tenebrata the central area of the hindwing is expanded towards the proximal margin, 
so that the black border runs almost parallel to the margin, whilst in the first two species it is widened at the 
anal angle. Panama. $ type from Chiriqui in the Berlin Museum. 
tenebrata. I. tenebrata sp. n. (61 c) resembles dilatata, but the forewing is as far as the discal band uni-coloured 
blackish-blue. The latter does not extend into the discal cell. Bolivia. $ type from Puerto S. Rosa (Garlepp) 
in the Berlin Museum. 
nigrivenata. I. nigrivenata sp. n. (61 c) resembles divisa, but the collar above with 2 red spots, the veins of the 
discal band are broadly bordered with black, like those of the hindwing. Colombia, Ecuador. G, $ type (Colom¬ 
bia) in the Berlin Museum. 
'Philomela. I. philomela Drc. has remained unknown to me in nature. It is said to have the cell quite hyaline, 
without the red spots of the collar, otherwise like the preceding. Central Colombia. 
In the following species the subapical band is absent. 
rhodobron- I. rhodobronclia Fldr. Collar with 2 white spots above, wings black, with a bhie reflection; the forewing 
eha. only with a white discal band, the hindwing with a greyish lustrous central area. Expanse of wings: 46 mm. 
A mazons. 
superba. I. superba Drc. resembles rhodobronclia, the forewing with a basal, the hindwing with a central whitish 
hyaline area. Panama, Guatemala. 
thabena. 1. thabena Dgn. Collar without white spots, with red scales. Otherwise similar to rhodobronclia, the 
veins in the discal band of the forewing broadly black. Hindwing uni-coloured. Colombia. 
I. lydia Drc. ( Phanoptis) is probably a Syntomid. 
13. Genus: «Fosiomor]>hoIcles gen.nov. 
Posterior tibiae with 2 pairs of spurs, in the forewing the 2nd to 5th radial branches are forked (in 
Josiomorpha the 2nd radial rises separately), the 2nd radial rising before the 5th, the 3rd palpal joint but slightly 
shorter than the second. In the hindwing the radial ramus and the 1st median branch are forked, the other 
veins rising separately. The species known resemble Dioptichs (Josia) in just the same way as the species 
of Josiomorpha do. Generic type: (Josia) gigantea Drc. 
gigantea. J. gigantea Drc. (= flammata Dgn.). Body black, with a blue lustre, patagia on the ground and 
collar laterally yellow, thorax above with a yellow median line. Abdomen above and laterally with yellow 
longitudinal lines, beneath whitish. Forewing with a yellow longitudinal line from the base of the proximal 
margin, in the G ending before the margin, in the $ on it. Hindwing likewise black with a yellow longitudinal 
stripe, the abdominal margin yellow. Colombia. —- Size and colouring similar to that of Josiomorpha penetrata, 
p. 431, t, 60 f. 
dognini. J. dognini sp. n. The G mentioned by Dognin as flammata belongs to a different species; from the 
preceding distinguished by broader yellow longitudinal stripes and the absence of the yellow dorsal side and 
white ventral side of the abdomen. Colombia. 
14. Genus; Sagaropsfs gen. nov. 
Chiefly agreeing in the structure with Josiomorphoides, the 3rd palpal joint being a third to a half of 
the second. Black species with yellow markings, the wings being shorter and broader than in the preceding 
genus. The imagines resemble Dioptids in the habitus. Generic type: ( Sagaris) horae Drc.
