marked characteristic. The front is very much shortened and the 

 lower part })rotrudcd so the pi'oboscis seems to come directly in front 

 of and between the eyes. The venation also is peculiar, 1 1 being 

 on a stem with 7, 8, 9 and 10, and so far out as to be at its base 

 nearer the end of the wing tlian the base of the stem.

MELANCHROIIN^. 



Only one genus, the typical one of this subfamily, has been found 

 in the United States, if, indeed, that has been found here. In our 

 catalogues several species are enumerated, and it is possible all may 

 be found in the extreme south of Florida, but I have been able to 

 find no record of the capture of any of them save ceplme Cram, 

 within our limits. 



This subfamily had always been regarded as Lithosian till its larva 

 was discovered, which showed it to be a true Geometer. It is, how- 

 ever, not typical, as the base of vein 8 of hind wings is scarcely 

 bent, and is not angulated. 



The species are brightly colored, as a ride, and decidedly showy 

 in appearance.
