FAM. GEOMETRID/ZE 225 
Wings with smooth, glossy scaling. Forewing narrow, costa straight, apex moderate, termen smooth, 
curved, very oblique, cell fully one-half, DC? curved, becoming oblique. SC! from cell, anastomosing 
or connected with C, SC? normal, anastomosing with SC! and then with SC?4, R! stalked, R? from above 
middle of DC, M! separate; hindwing narrow, costa long, apex and termen rounded. tornus not 
pronounced, cell one-half, DC incurved, rather oblique, C closely approximated to cell to one-half, 
SC? stalked, R? characteristic, M! separate. 
Early stages unknown. 
No doubt related to the two preceding genera, yet not very closely. The shape and texture and 
the smoother palpus distinguish it from Mixochroa, otherwise the characters are nearly the same.

Characters. — Face smooth. Palpus in both sexes usually short to quite moderate (only elongate 
in one or two doubtfully-placed species), second joint with moderately appressed scales, third joint in 
both sexes usually small (long in ///iana Q j. Tongue present. Antenna in cf, and usually in Q , bipectinate, 
with apex nearly simple 2). Pectus and femora hairy. Hindtibia in c usually not dilated (dilated, with 
hair-pencil, in rubrimargo and one or two others), in both sexes with all spurs. Abdomen not crested. 
Forewing with costa arched, apex moderate to rather acute, termen moderately oblique, entire, rather 
straight anteriorly, more curved posteriorly. sometimes appreciably gibbous in the middle, cell less 
than one-half, DC deeply incurved, SC! from cell, free or anastomosing with C, SC? normal, R! just 
separate or stalked, M! separate or connate; hindwing with termen rather strongly convex, often elbowed, 
or even shortly tailed at R?, cell less than one-half, DC? deeply inbent anteriorly, oblique posteriorly, 
C approximated to cell to near middle, SC? stalked (usually shortly), M! approximated to short-stalked. 
cf genitalia (cArysoprasaria) : uncus parallel, with socii, gnathos pointed, harpe with clavus extended to 
two strong horns, penis pestillate, vesica with band of small cornuli, eighth sternite terminating in two 
blunt points. 
Ecc. — Very flat, laid in piles of twelve to fourteen, standing out at right angles from twig like a 
small branch (Newman, T/e Entomologist, Vol. 6, p. 168). 
1) Probib!y the majority of synonymists would argue that the present genus was the true /oZis of Hübner, and Hübner's name has been 
employed in that sense by Turner, Proc. Linz. Soc. IN. S. Wales, Vol. 35, p. 579. The species cAxysoprasarra, under tbe name of verzax:a, is placed 
first in Hübner's VerseicAiss, which would weigh with many; while Stephens' restriction (though uncharacterized) has three years' priority over 
Lederer's (characterized) restriction, and eight over Guenée's work. We fihd, however, that a literal application of the International Rules of Nomen- 
clature saves the current usage. Guenée was the first to « select a type » for 7oZ£s, and he selected Zacfearta (Sec. Gén. Lé$. Vol. 9, p. 353, 355). 
2) There is much variability in detail between the different species. We are unacquainted with the O of the type species, but Warren (Jovi. 
Zool. Vol. 1, p. 393) says it is bipectinate, as indeed would have been expected.
