broadly banded with black; palpi nearly black, tips of the joints whitish; legs pale 

 brownish, tarsal joints marked with dark brown. Abdomen yellowish brown, the 

 penultimate ventral segment with a black spot; fore-wings nearly uniform brownish, 

 but the stigmal region darker, and outer margin rather darker; hind wings grey 

 with darker veins; at anal angle is a spreading fascicle of long hairs, nearly as long 

 as width of fore wings. Fore wings slender, outer margin nearly truncate, discal 

 cell longer than pedicel, the first apical not so far back on the cell as in M. minor; 

 the median vein does not reach outer margin; fork five does not reach as far back as 

 fork one; the hind wings are broad, the anal portion twice as broad as the other 

 part; venation similar to M. minor. The male appendages are long, similar to 

 M. minor, but the tip enlarged, and a pair of upcurved lateral pieces within the larger 

 appendages. Expanse 19 mm. 



From Madeira Mamore River, Matto Grosso, Brazil (Mann 

 coll.). 



Macronematid.e. 



Leptonema crassum Ulmer. 



Camp 43, Madeira Mamore River, Brazil (Mann and Baker coll.) 

 and Manaos, Amazonas, Brazil (Mann coll.). Known from Brazil, 

 Ecuador, Colombia, and Central America. 



Leptonema externum sp. now 



Pale yellowish white, a dark cloud near the stigma, two black dots near costal 

 base of fore wings and a black dot on outer base of basal joint of each antenna, 

 rest of antenna? faintly annulate; vertex tuberculate near base of antenna?, clothed 

 with fine short hair; third joint of maxillary palpi rather more than one-half the 

 length of the second, much swollen below, fourth joint about one-half as long as 

 third. Wings of moderate length, median cell very broad, fifth apical some dis- 

 tance back on the median cell, discal rather longer than broad. Expanse -25 to 30 

 mm. 



From Camp 41, 360 Kilometers from Porto Velho, Brazil (Mann 

 coll.). 



Leptocerid.e. 



Leptoeella jenseni Ulmer. 



One from Camp 43 Madeira Mamore River, Brazil (Mann coll.). 

 Although much rubbed it secerns to agree with cotypes of this 

 species from Argentine. 



(Feet in a sp. 



One specimen, with the anastomosis strongly marked; not (E. 

 excisa, for fork one is quite long pedicellate. 

 From Manaos, Amazonas, Brazil (Mann coll.).
