the 7th and the anal brush of the same colour, ventrum light yellow. Legs chiefly yellow, hut lighter than the 
body, the tibiae and the tarsi of the hindlegs with thick and long hair-tufts varying between a lighter chrome- 
yellow, brown and blackish. Forewing transparent with a yellow spot at the base, the broad costa and the 
likewise broad, obliquely cut off distal margin as well as the veins brownish black, the distal area with four 
veins. Hindwing transparent, veins and margin bronze brown. Fringes of all the wings greyish bronze. 41 mm. 
Amazons, Iquitos. Owing to the beautifully haired legs, the size and the shining body, the insect numbers 
among the most beautiful species of Melittia. 
M. pauper Le Cerf (180 a). Head greyish brown, white before the eyes. Palpi white at the base beneath, pauper. 
yellowish outside and above, with a few brown scales in the middle of the 2nd joint (antennae absent). Collar 
and thorax greyish olive, beneath with a white spot on each side. Abdomen greyish olive, all the segments 
finely margined with whitish, ventrum dingy yellow. Anal tuft small, yellowish. Legs yellowish white warming 
into olive grey. Hind tibiae and tarsi rather long, with yellowish grey hair. Forewing transparent, costal and 
distal margins as well as the discal mark rather broadly olive grey, a sharp longer dent of the same colour ex¬ 
tends from the discal vein inwardly into the hyaline area. Hindwing transparent, veins and the narrow margin 
olive grey. Fringes of all the wings dull grey. 32 mm. Peru, Lima. March. 
M. riograndensis Breth. has been described in: Anales de la societad rural argentina 54 (1920), to which riogranden- 
there was no access. 
(29a.) Genus: Xjeuthiieria dalla-Torre. 
L. ruficincta Fldr., named and figured as Eublejoharis Fldr. in: Reise der Novara Zool. 4, pi. 75, fig. 4 ruficincia. 
(1874), described in Seitz Vol. 14 (Africa), p. 531 as Melittia (Sudan); the statement “South America" 
in Junk's Cat. 31 Aegeriidae remains unintelligible. It has thus been twice introduced, once as Melittia and 
once as Leuthneria for Africa and for America. The unique insect does not make the impression of a Melittia 
in Felder’s work, for which reason dalla-Torre proposed a new description of Leuthneria ; there exist, how¬ 
ever, neither descriptions for Eublepharis , nor for Leuthneria. 
30. Genus: Clallitlifa Le Cerf. 
Antennae of medium length, thin at the base, thickened before the end. Palpi rising, small and pointed. 
Proboscis well developed. Thorax convex, abdomen delicate and rather short with a small anal brush. Feet 
long, especially the posterior ones, their tibiae with dense and long hair in the last quarter, which decoration 
is also continued on the tarsi. Forewing: vein 1 fine, not divided at the base, 2 and 3 arise before the interior 
angle of the cell, separated at the base, 4 from the interior angle of the cell, 7, 8 and 9 stalked, proceeding from 
the anterior angle of the cell. 10 and 11 separated at the base and then nearing each other. Hindwing: 1 a short, 
2 and 3 before the interior angle of the cell, 4 from the angle, 6 absent, 8 confluent with the costal vein, no 
anal lobe. Type: C. oberthuri Le Cerf. 
C. oberthuri Le Cerf (180 a). Head blackish bronze, white behind, a few white scales below the base oberthuri. 
of the antennae. Palpi erect, black, white in front. Antennae black, the apex above and the club beneath 
brownish red. Collar brownish bronze. Thorax shining black, metathorax the same with two yellow lateral 
spots. Abdomen dark chocolate brown, the margins of the segments black, the two last quite black, the anal 
brush almost black. Metathorax beneath yellowish, the two first segments black, the following ones yellow. 
The posterior margins of the 1st and 3rd segments above very finely light yellow. Forelegs black, reddish 
beneath, femora and tibiae of the middle legs black with little yellow. Hind femora black, white beneath, a 
few white hair-scales above at the beginning, a light yellow spot outside, almost in the middle. After this the 
Melittia-Yike hair begin, passing over to the tarsi the last joints of which, however, are hairless. Forewing deep 
chocolate brown, hindwing transparent, opalescent blue, margins and veins chocolate brown. 34 mm. Cundina- 
marca, Colombia. Le Cerf, in 1900, had only 1 at hand for examing this species; later on, Fassl brought 
a larger number from Muzo (Colombia), but unfortunately also only all of which exhibit somewhat less 
distinct yellowish white markings than the $ of Le Cerf. 
31. Genus: Calasesia Beut. 
Palpi erect with appressed scales, extending to the height of the head, 3rd joint long and narrow. 
Antennae gradually thickening towards the apex, then short and pointed towards the end. Legs scaled, hind¬ 
legs with small hair-tufts on the spurs of the tibiae, tarsi tuftless. Abdomen tapering, anal tuft small. Fore¬ 
wing remarkably round at the apex, with 10 veins: 3—6 from the cell, 7 and 8 grown together, 10 from the 
base. Hindwing: vein 2 from the cell, 4 and 5 from the end of the cell, 6 from the middle, 7 and 8absent. 
Type: C. coccinea Beut. 
C. coccinea Beut. (180 b). Head black. Palpi yellow, black in front. Collar whitish in front. Thorax coccinea. 
and abdomen blackish bronze with a metallic reflection. Antennae brownish black. Thorax beneath with
