are known from Brazil on\y , coliigu ay œ (Philippi) from Chile. The 

 North American species are : columbianus (Ashmead) [Florida, District of 

 Columbia, New Jersey] ; and ce?ieoviridis Girault (Illinois). Of the six 

 species of the genus, four are South American and two North American, 

 and the genus as a whole is distributed between the meridians of 40.6° and 

 89.2° west longitude, and between the parallels of about 40" south and 42° 

 north latitude.

 (Continued from page 22.) 



Leucania suavis, sp. nov. 



Head and thorax clothed with olivaceous hair; primaries straw- 

 coloured, slightly sprinkled with black atoms, especially along inner 

 margin ; a dark shade extends from base of wing above cubital vein and 

 along vein 5 to outer margin ; veins in outer portion of wing finely lined 

 on both sides with dusky ; an indistinct oblique row of black dots across 

 the wing beyond the cell, not attaining costa; a faint row of black marginal 

 dots, mostly incomplete ; fringes whitish. Secondaries deep smoky in 

 $ , fringes pale, cut by a dark line ; in ? smoky, but much lighter than 

 in c? , an incomplete row of terminal dots and pale fringes without dark 

 line. Beneath primaries smoky, outer margin and a ray extending 

 outwards from discocellular vein pale straw-colour ; secondaries pale, 

 slightly suffused with smoky ; a small discocellular spot and incomplete 

 row of terriiinal dots on each wing. Expanse, 31 mm. 



Habitat : White Mts., Ariz., i c^ , 6 Ç s. Type, collection Barnes, 

 Our single c^ specimen shows a black dot at the inception of vein 2 

 of primaries, and another below it on anal vein ; these are lacking in the 

 V s. The species may easily be separated from all other N. Am. 

 species of the genus Zeucama, as defined by Hampson, by the fact that 

 there are no black lines in the interspaces of the veins in the terminal 

 area. 



Trachea cava, sp. nov. 



Palpi blackish outwardly ; head and thorax clothed with an admix- 

 ture of reddish-ochreous and black scales ; an indistinct black transverse 

 line on tegul?e and a rather more distinct black line before upper margin
