the tip where they are abruptly truncate, the angles a little prominent 

 and round. Near the base of this piece is a corneous ridge from which 

 arises a broad hatchet-shaped piece slightly concave at underside. 



With bicarnea ends the section with apices of jirimaries rounded. 

 The remaining species of the first division have the apices at least 

 rectangular and usually somewhat produced. C-nignim is a very well 

 known species common to both continents, distinguished by the dark 

 primaries, and the open V-shaped orbicular, which is reddish. The 

 thorax has distinct but low anterior and posterior tufts. The S geni- 

 talia consist of broad harpes, the tip of which is oblique, the inferior 

 angle somewhat elongated, the inner side of tip spinulated. The infe- 

 rior extension of the tip is corneous, and imitates an oblique corneous 

 ridge extending to upper margin and there produced into a short pro- 

 jecting spur. 



RospitaUs is well defined from the preceding by the reddish-brown 

 color. The 9 only is thus far known. 



Perconflua is closely allied in maculation, but is a broader winged 

 species, with primaries more evidently trigonate, the apices less pro- 

 duced. Of this species also, I have seen no $ . 



With this species ends the first division : the remainder of the species 

 are divided by color and maculation. 



PhyJlophora is a large broad-winged species, bright red brown in 

 color, the maculation well defined, the lines irregular. The thorax is 

 rather indistinctly tufted, the basal tuft evident. The $ genitalia are 

 decidedly peculiar. The harpes are corneous, incurved around the 

 tip, forming a cavity under the rim, partially covered by an irregular 

 horny plate. A reference to the figure will explain better than words. 

 It is certainly the most remarkable structure known to me in any 

 agrotid, 



Bubifera is a smaller, shorter winged species, darker, more sordid 

 brown in color, with very regular transverse lines, and hardly contrast- 

 ing maculation. The getutalia are of a somewhat more normal type. 

 The harpes are broad at base, very abruptly strangulate near tip, the 

 latter oblique, inwardly spinulate, with a bunch of diverging spines at 

 inferior angle. The clasper is distinct, bifurcate, the inferior fork long, 

 stout, regularly tapering to an acute tip. The superior branch is 

 shorter, stouter, curved, also acute at tip. 



Oblata, of which hilUana is a synonym, is a bright species more yel- 

 lowish in color, with contrasting, well-defined maculation. The orbicu- 

 lar is large, oblique, and open sui)eriorly. The thorax is distinctly 

 tufted. The $ antenna? has something of the moniliform type. The 

 joints fringed laterally by stiff, short hair. The genitalia are distinct- 

 ive. The harpes are rounded at tip, furnished with a finger-like pro- 

 jection at inferior margin behind which the piece suddenly widens and 

 becomes somewhat corneous, the widened portion gradually merged
