54. Genus: Agyrtidia Hmps. 
This genus containing one of the largest of all the Syntomids known hitherto, is characterized by a 
woolly haired thorax, broad wings in which all the subcostal veins stand on a joint pedicle. The 1st radial rises 
below the cell-angle, the lower radial veins separately. On the hindwings the lower median and lower radial 
veins stand on a joint pedicle. 
A. uranophila Wlcr. (17 a) is easily recognizable by the size and the metallic blue bordering of the uranophila. 
large hyaline spots. The black abdomen exhibits a metallic blue dorsal band, similar, though profusely white- 
dusted subdorsal stripes and an entirely white underside. Brazil, Peru and Bolivia (Coroico). 
55. Genus: Macrocneiiie Hbn. 
This genus contains numerous species of mostly very similar insects difficult to discern, of black colour 
decorated with blue and green metal-colours and very characteristic by the long hindlegs the tibiae and tarsi 
of which are provided with more or less long-haired scales. The erect palpi extend beyond the head. The antennae 
with a thickened median part are in the d long-combed, in the $ mostly serrate-dentate. The neuration does 
not offer any peculiarities. As to the biology, comp, the General Topics (p. 36). 
M. cyanea Btlr. (17 a) resembles the following species, but it has cpiite blue forewings except the cyanea. 
apex. Brazil (Rio de Janeiro); also from Peru. 
M. lades Cr. (= leucostigma Perty, naja Bunn.) (17 a). Easily recognizable by the white tips of lades. 
the posterior tarsi and the expansion of the bluish-green colour on the forewing, extending only as far as the 
cell-end and being crossed by an oblicpie, velvety-black band near the base. The golden green abdomen exhibits 
at the base above 2 white dots, the ventral side being spotted white. A very common species, widely distributed 
from Mexico to Peru and Argentina. — ab. ferrea Btlr. has a metallic blue abdomen, the black oblique band ferrea. 
separating the blue basal colouring from the disc is reduced. Described from Espiritu Santo. — In specimens 
from Peru: chionopus form. nov. -—■ the hairy cover of the whole posterior tarsi is white. chionopus. 
M. cupreipennis WJcr. (17 a) is a larger species easily recognized by coppery lustrous, golden green cupreipen- 
colour covering the whole insect. The tips of the antennae are white, and so are also dots on the forehead, nis - 
collar, base of palpi, forehips, base of femora, on the dorsum of the first abdominal ring and on the ventral 
side of the middle segments. Brazil, the exact habitat not being stated. 
M. caerulescens Dogn. Palpal base in front white; on the forehead 2 white dots; collar with white caerules- 
dots and single blue scales. Abdomen black with a metallic green reflection, on the 1st ring 2 lateral white cens - 
dots. The venter exhibits in the middle a series of white dots. The legs are black with blue scales, at the joints 
dotted white. The black forewings are in the basal half between the veins of a radiant metallic bluish-green, 
so are the hindwings in the disc. Expanse of wings: 37 mm. Venezuela (Merida). 
M. semiviridis Druce. Anterior body black, tips of antennae white, abdomen and legs bluish-black; semiviridis. 
the first abdominal ring with lateral white spots; the venter exhibits a middle row of white spots. Forewings 
black, in the basal half between the veins metallic bluish-green; hindwings bluish-green with a broad black 
margin. Expanse of wings: 50 mm. Colombia. 
M. nigricornis SchrottJcy has a black body with a green reflection, and white spots on the collar, pro- nigricornis. 
thorax, first abdominal ring (subdorsally), chest and the two first ventral segments. Forehips dark blue. Wings 
above with a faint metallic green lustre, beneath dark brown. Expanse of wings: 33 mm. Argentina. 
M. adonis Druce (17 b). Discernible from the similar species with quite black tarsi by the extension adonis. 
of the blue colour on the forewing reaching almost to the margin, here mostly with an intense violet lustre. A 
golden green stripe at the proximal margin extends as far as the base. A metallic blue spot on the hindwing 
is usually more strongly developed than in the allies. Distributed from Mexico to Panama. — The example 
figured in the Biologia from Chiriqui has no blue in the apical part, but instead a blackish stripe runs from 
there to the transverse vein (= ab. 1 Hmps.). 
M. cinyras Schaus (17 b) differs from the very closely allied adonis by the blue colour of the forewing cinyras. 
not forming an extensive surface, but consisting only of stripes between the veins behind the cell from vein 
5 down as far as the proximal margin. In the discocellular itself there is only a narrow blue stripe near the 
upper end. Described from Mexico (Jalapa, Coatepec).
