dash and the shading along the inner margin less heavy. Some speci- 

 mens of incresa show a tendency for the orbicular and reniform to 

 become more or less indistinct but the t. p. line of that species, when 

 visible, is scarcely produced to points on the veins, whereas the t. p. 

 line of heinrichi is produced to longer points than in any described 

 North American species. Messrs. Schaus and Heinrich have kindly 

 compared the type with the National Museum Mexican Collection and 

 inform the authors that the species is unrepresented. 



Type locality: Mohave Co., Arizona. 



Number and sexes of types: Holotype $ , no date, unique. 



SuPRALATHOSEA gen. nov. 



Proboscis fully developed but not long ; palpi obliquely porrect to just 

 bej-ond the frons and fringed with long hair below; frons slightly roughened 

 but without any processes or raised edges, rather flattened, clypeal corneous 

 plate scarcely developed ; antennae of male bipectinate from base to tip, the 

 branches long ; of female simple ; head and thorax mainly clothed with scales ; 

 tegulae produced into a hood which may or may not be erected ; tibiae fringed 

 with rather long hair, unarmed ; tarsi unarmed except for the usual spines ; 

 abdomen with a slight crest on basal segment only, rather smoothly scaled and 

 without fringes of hair. Fore wing long and narrow, the apex somewhat 

 produced, the term.en obliquelj' curved ; veins 3, 5 from near angle of cell ; 6 

 from areole; 7 shortly stalked; 9 from 10 anastomosing with 7 + 8 to form 

 the areole; 11 from cell. Hind wing with veins 3, 4 from angle of cell, 5 

 obsolescent from only slightly below middle of discocellulars ; 6, 7 shortly 

 stalked from upper angle ; 8 anastomosing with the cell near base only. Discal 

 dot on underside of hind wing distinct, small, unconnected to the base of the 

 wing by any black scales. May be placed between Copicucullia and Lathosca, 

 (see 1922, B. & Benj., Contr. N. H. Lep. N. A., V, (1), 28-29). 



SuPRALATHOSEA BABOQUIVARIENSIS sp. nov. 



$ . Head, thorax and abdomen dull grey, mixed with some black and 

 white. Primaries : ground color dull grey more or less suffused and irrorated 

 with white. All ordinary lines and spots more or less obsolescent, not easily 

 distinguishable ; fringe nearly concolorous, obsolescently interlined with whitish 

 and checkered with black. Secondaries: nearly pure white; a faint discal dot; 

 some fuscous scales scattered over the costal region, on the veins, and along 

 outer margin which is also marked by black dots between the veins. Beneath: 

 primaries dull whitish-grey, fringe as on upper side ; secondaries and their 

 fringes as on upper side but with the discal dots black, small, distinct, points. 



9. Similar to the male; darker; more or less suffused with black rather 

 than white; the transverse maculation obsolescent but better marked than in
