Holotype, d", Teffe, January 1, 1920 (H. S. Parish). 



Ozodicera triguttata is distinguislied from the other members of 

 the subgenus by its large size and comparatively heavily spotted 

 wings. It is closest to 0. (D.) fwmipennis Loew, likewise from 

 Brazil, in which the male measures between 17 and 18 mm. in length, 

 the antennal fiagellum is almost black, the wings dark yellowish 

 brown with only a smoky black cloud at r-m and with the body 

 coloration different.

Generally similar to the male, differing as follows: Flagellar 

 pectinations a little shorter than in the male, the longest being 

 about as long as the segments that bear them. Abdominal tergites

Ozodicera (Ozodicera) extensa sp. n. 



Antennal pectinations long, each strongly bent at about one- 

 third its length, at the angle with a short spur that bears a bristle; 

 mesonotal praescutum brown, the stripes very indistinct; wings 

 strongly brownish, the costal and subcostal cells darker; a dark 

 brown cloud at the fork of Rs; male hypopygium with the lobes 

 of the tergite provided with brushes of long yellow hairs; each 

 sterno-pleurite produced caudad into a long, slender, chitinized 

 rod that is dilated into a spinulose apex, at the extreme tip bearing 

 a spine. 



Male. — Length 15.5 mm.; wing 13.6 mm. 



Frontal prolongation of the head brown; palpi dark brown. An- 

 tennae uni-pectinate, scapal segments obscure yellow, flagellar seg- 

 ments brown, the pectinations dark brown; flagellar pectinations 

 elongate, each strongly bent at about one-third the length, at the 

 angle with a slight spur that is tipped with a small bristle. Head 

 brown. Mesonotal praescutum brown, the stripes very indistinct;
