ance and is further characterized by the flat hairy appressed 

 thoracic vestiture with slight tuft of metallic scaling on meta- 

 thorax and no abdominal tufting. In antonito Barnes the thoracic 

 vestiture is loose and composed chiefly of large spatulate scales; 

 there is a slight divided tuft on the metathorax and a small tuft 

 on the basal abdominal segment; the cf antennae show a rather 

 peculiar structure in that they are very strongly lamellate, each 

 ' lamella being considerably excavated centrally, th€ two ends thus 

 projecting far beyond the central portion and presenting to a 

 casual glance the appearance of bipectinations; the fore tibiae are 

 unarmed, the palpi short, upturned, with 3rd joint rather porrect 

 and the tongue is well developed ; the species evidently represents 

 a new generic type for which we would propose the name Mimoba- 

 rathra; besides the cf type of antonito we have six further cf 's from 

 White Mts., Ariz., before us from which we have drawn up the 

 above generic characterization. The so-called 9 type of antonito 

 Barnes labelled "So. Arizona, Poling" does not, as -already men- 

 tioned, belong to this species at all; it has naked eyes, unspined 

 tibise, the fore tibiae however with well developed apical claw on 

 inner side; the thoracic vestiture is composed of loose spatulate 

 scales, but the specimen is too rubbed to determine the nature of 

 the tufting. It would fall into Hampson's subfamily Acronyctinae 

 and according to his tables belong either to the genus Copanarta 

 Grt. or to Leucocnemis Hamp. It is apparently undescribed and 

 bears but little affinity to the already described species of either 

 of these two genera, but as the specimen is considerably worn we 

 dislike to create a new genus for it and place it provisionally in 

 Leucocnemis Hamp, with following characterization: —  



Leucocnemis barbara, sp. nov. 



Head and thorax clothed with an admixture of white, black 

 and pale ochreous scaling; primaries white, heavily sprinkled with 

 smoky, the ground colour almost obliterated and only showing 

 distinctly' in subterminal area; basal area sprinkled with orange 

 scaling, especially before lower portion of t. a. line, which is black, 

 outcurved and lunulate; orbicular round, orange, with dark cen- 

 tre and black outer line; reniform broad, figure-of-eight-shaped, 

 open above and below, with pale centre broadly margined with
