Geometridae of the Argentine Rejntblic. 
brown, darker spotted, beneath white ; antenna basally white above, 
otherwise brown, ciliation very short. Wings white. Forewing 
above between costa and vein C fuscous to beyond one-half; mark¬ 
ings light fuscous brown ; antemedian line scarcely indicated, a spot 
on costa at nearly two-fifths and one on inner margin at nearly one- 
half indicating its position ; a median line or shade indicated by a 
spot on costa at about middle, and one on inner margin beyond 
middle, and faintly traceable in submedian area in fi’esh .«pecimens; 
postmedian line at nearly three-fourths, indicated by a distinct dark 
spot on costa, and a rather indistinct, curved series of vein dots ; 
subterminal area with light fuscous clouds, the smaller being across 
R*, the larger almost continuous, band-like, from above R® to inner 
margin, but really divisible into two spots on R^ and M* and a small 
band starting proximally to these, just above JVP, and reaching to 
inner margin just before tornus ; some more indistinct terminal 
clouding ; cell-spot blackish; marginal line blackish, interrupted at 
vein-ends. Hindwing weakly marked, faint suggestions of post¬ 
median line and sub terminal clouding ; marginal line as in fore- 
wing. Underside with costal margin tinged with brown, less darkly 
than above, but more broadly (about to SC) and reaching to apex; 
cell-spot of forewing usually present; otherwise almost without 
markings ; marginal line of both wings nearly as above. 
Buenos Aires, 3 collected by A. F. Bayne, February 10, 
1903 (type), February 23, 1906, and one without date, all 
in coll. L. B. Prout. A fourth from the same locality, 
in coll. Br. Mus. (H. Wilkinson). 
The ^ is still unknown. The $ has four well-developed 
spurs and the double areole as in Hamcdia', but in the 
hindwing- SC“ and are stalked for nearly one-half their 
length. 
SCELOLOPHIA (Hulst). 
Scelolophia, Hulst, Tr. Amer. Ent. Soc., xxiii, 301 (1896). 
Calyptocome, Warren, Nov. Zook, vii, 148 (1901) (nov. syn.). 
The ^s of this genus can readily be distinguished from 
Hamalia by the tufts or fringes of hair on the hindwing 
beneath, the $s by having the outer median spur extremely 
small, or often wanting. I have found variation in the 
latter point between very close allies; thus it is present in 
Scelolophia phorcuria (Guen.), absent in>S'. roseo/wa (Warn), 
which is sunk at the British Museum to phorcaria ; see 
also Warren, Proc. U.S. Mus., xxx, 437. 
Mr. Warren, in erecting Calyptocome, overlooked Hulst’s
