MACRONEMA ERICHSONI, sp. nov. 



TYPE. M. C. Z. 10,902. French Guiana: Nouveau Chantier, 

 June (Le Moult). 



Black; palpi, pronotum, and most of legs pale yellowish, the front tibiae 

 and the tips of the others blackish. Fore wings mostly black; two subbasal 

 streaks, an upper median spot, a transverse band before stigma, and two 

 elongate spots in the lower apical part of wing are hyaline. Hind wings with 

 dark veins; the tip, a small costal spot, and extreme base dark. Wings 

 moderately slender, the discal cell of good size, as long as broad; the median 

 cell rather small, three times as long as broad, its tip not beyond tip of discal 

 cell; first fork with short pedicel. In the hind wings the radius runs into the 

 first sector, and the cross-vein is at base of the fourth fork. 



Expanse 22 mm. 



PODOMACRONEMA, gen. nov. 



Related to Plectromacronema, but the spurs are 2, 4, 4, and the front leg 

 (in male at least) has the tibia and basitarsus broad and flattened, as is 

 seen in the middle legs of other genera. Head much swollen in front, ver- 

 tex with triangular plate hardly as prominent as in Plectromacronema; 

 maxillary palpi slender, second 1 joint much longer than the third or fourth 

 which are subequal. Venation much as in Plectromacronema, and the outer 

 side of the fore wing excised near middle. 



TYPE. P. subfuscum, sp. nov. 



PODOMACRONEMA SUBFUSCUM, sp. nov. 

 TYPE. M. C. Z. 10,904. Argentina Misiones, 1909 (Jorgensen). 



Yellowish brown; head more yellow, the swollen face brown; antennae 

 yellow, the joints narrowly dark at tip; thorax dark brown, abdomen yellow 

 brown, darker at tip; legs pale, front femora rather dark, front tibia and basi- 

 tarsus with a dark band. Fore wings brown, some pale patches in the costal 

 area; a long, hyaline streak Behind the radius, several small spots near the 

 anastomosis, and five silvery marks in apical region; an oblique, curved mark 

 over basal parts of second and third apical cells, a small spot beyond of fourth 

 apical cell, two narrow bands from the costa, the outer one the longer, and 

 parallel to outer margin, and a fainter streak in the first subapical cell. Hind 

 wings brownish, darker on tip and along the cubitus. The first sector unites 

 for a short distance with the radius and then separates. 



Expanse 34 mm.
