GEOMETRIDAE 
It is with some hesitation that we venture to describe the follow- 
ing species, as it is quite within the bounds of possibility that they may 
prove to be Mexican or West Indian. We have however consulted 
Druce and Guenée as fully as possibly without finding descriptions or 
figures that would suit any of these species; Mr. J. A. Grossbeck has 
also examined the larger proportion of these and pronounced them 
as unknown to him. We therefore consider it better to bestow names 
upon them since the types of the Mexican species are so scattered as to 
render comparison a very long and tedious task; our figures should 
render identification easy, and allow those who have better opportu- 
nities of examining the types than we have to draw their conclusions. 
Unless the species are misplaced generically in our present lists we 
believe there are at present no N. Am. names that we can apply to our 
species. 
XNANTHORHOE COLUMELLOIDES sp. nov. 
é. Palpi, head and thorax ochreous sprinkled with brown, antennae 
strongly bipectinate; primaries crossed by alternate white and brown scalloped 
bands; these in the basal third of wing are rather indistinct and inconspicuous, 
about five in number; the median area of wing is crossed by five brown scal- 
loped lines, the first and fifth corresponding to the antemedial and postmedial 
of other species, the antemedial line is preceded by a broad white line, defining 
the outer boundary of the basal area, lines two and three are widely separated 
at costa but approaches and are more or less conjoined below cell, forming a 
series of two or three pale diamond-shaped patches above inner margin; the 
large costal patch contains a brown spot in the cell; lines 4 and 5 are close to- 
gether, the intervening space filled with pale ochreous, line 5 very strongly 
scalloped and followed by a broad white line; beyond this are three brown 
scalloped parallel lines, the intervening space filled with pale ochreous; this area 
is bordered outwardly by a prominent, broad, white, scalloped, subterminal line; 
terminal area brown, sprinkled with white scales and with broken brown terminal 
line; fringes white, checkered with smoky. Secondaries whitish with lines of 
primaries faintly reproduced in basal 2/3, but strongly marked in subterminal 
area, the white subterminal line and a preceding smoky line being particularly 
noticeable; terminal area even smoky brown with darker terminal line, fringes 
checkered. Beneath, basal portion of costa of primaries ochreous with a few 
brown streaks representing inception of brown lines of upper side; basal por- 
tion of wing smoky, paler along inner margin; subterminally the lines of upper-
