M. chrysitis Guer. (= iole Druce) (17 b). Most similar to lades (17 a), distinguished by the quite black 
tarsi and the more golden green, not so blue colour, and usually larger size. The black oblique band near the 
base is considerably narrower. Likewise widely distributed and common from Mexico to Rio Grande do Sul. 
-—■ deceptans form. nov. (= ab. 1 limps.). Specimens from Guatemala and Rio Grande do Sul occasionally 
exhibit some white colour at the extremest tips of the posterior tarsi. 
M. laconia Druce (17 b). The wings are unicolorously black, only at the base there are some metallic 
blue scales. Forehead, vertex, collar, sides of thorax, and hips are metallic blue. The black abdomen shows 
on the dorsum and at the sides likewise blue spots, the first two segments being ventrally margined with blue. 
From Mexico and Guatemala. 
M. nordina Schaus looks very much like the .preceding. Body black; outside of the palpi, spots on the 
forehead and vertex, as well as the forehips metallic bluishgreen, of the same colour are spots on the mesothorax; 
at the sides of the abdomen a broad, metallic green stripe. On the black forewings there is at the base of the 
proximal margin a metallic bluish-green stripe. Expanse of wings: 35 mm. Distributed in Mexico (Guadalajara, 
Zacualpan, Cuernavaca). -—- In specimens from West Mexico (Guerrero) there may occur orange colouring on 
the collar and posterior tarsi: altilis form. nov. (17 b). 
M. maroniensis Schaus has a black body; the base of the femora, and forehips are white, ventral valve 
margined with white. The venter exhibits 2 rows of white spots. On the head and thorax there are dispersed 
blue scales; behind the eyes in the distal half of the collar and on the shoulders white dots. The wings are black, 
the forewings lighter towards the apex. Expanse of wings: 24 mm. French Guiana. 
M. evelina Druce (17 c) is the only Macrocneme exhibiting above on the forewings a large white apical 
spot; the blackish-brown ground-colour turns somewhat lighter brownish towards it. Forehips and base of proxi¬ 
mal margin of the forewing with metallic blue spots. Tips of antennae white. Occurs in Mexico and Panama. 
M. immanis Hmps. (17 c) is the largest species and differs from the similar ones by its quite black 
thorax and the absence of the basal white dots of the forewing. Both the wings are uninterruptedly bluish- 
green as far as beyond the cell. Bolivia, also from Ecuador. 
M. thyra Moschl. (17 c) is much smaller than the preceding and besides different by its metallic green, 
not black thorax, and white basal dots of the forewings; the green colour of the basal half is interrupted by 
a black oblique spot below the base of the cell. On the under surface the proximal margin of the forewing and 
the base of the hindwing are white. Chest and venter are white in their whole extent. Expanse of wings: 38 mm. 
Guiana, Brazil to Peru. From Colombia and Trinidad there originates a form with an uninterrupted green 
basal part of the forewing and without any white beneath: intacta subsp. nov. (= subsp. 1 . Hmps.). — In boli- 
viana subsp. nov. the green colour of the wings extends as far as the margin. Bolivia (Rio Songo). 
M. thyridia Hmps. (17 d) has, like the preceding, a coppery lustrous abdomen, but is immediately 
discernible from it by its entirely black, and not white, under surface exhibiting only a middle row of minute 
white spots. The forewings exhibit like in chrysitis and lades a black oblique band in the basal third; the greenish 
golden colour occurring also on. the under surface, is not spread far and varies greatly by being brassy golden 
to copper-coloured. The bases of all the wings are to a small extent whitish beneath. Surinam, Venezuela. 
M. affinis Klages differs from the preceding by its black thorax being subdorsally striped metallic 
blue, and blue-striped shoulder-covers being in the $ not bordered with white. Forehips and posterior tibiae 
striped blue, the latter without any white at the ends. Abdomen like in thyridia. The forewings, with only 
1 white dot at the base of the costa, are striped metallic blue, not green. Expanse of wings: 36 mm. Venezuela. 
M. maja F. (17 c). Black; tips of antennae white; forehead, palpal base, collar, chest, forehips and 
1st abdominal ring dorsally with white dots. The abdomen shows subdorsal, metallic green stripes, lateral 
and ventral rows of white dots. Forewing in the distal half as far as the margin suffused with metallic bluish- 
green, frequently with continuations towards the base below the median and at the proximal margin; at the base 2 
white dots. Hindwings with a bluish-green apical spot. Expanse of wings: 38 mm. Surinam; Amazon (Para). 
M. guyanensis Dogn. Black, thorax and abdomen with a green lustre; palpal base, forehead and 
collar dotted white, so is the 1st abdominal ring subdorsally and sublaterally. Ventral valves black, on each 
side with a white dot. Venter quite black with single green scales. Hips black. Wings black, with subcostal 
green stripes, also below the median and at the proximal margin; in the disc of both wings metallic blue scales. 
Expanse of wings: 31 mm. French Guiana. 
M. cyanescens Dogn. Body black; forehead, collar, shoulder-covers, thorax, hips and legs with metallic 
green spots. The abdomen shows dorsal, subdorsal, and sublateral green spots; ventral valve metallic green. 
Wings black with a deep violettish-blue lustre, at the base a little metallic green. Expanse of wings: 42 mm. 
East Colombia.
