p. 2; the pupal cremaster is similar to that of Brephos, but there are few other points of contact between 
the two genera. Several authors consider that there is a real relationship between Alsophila and Pcileacrita 
Riley, which on account of the loss of the 2nd radial of the hindwing is definitely assignable to the Geometrinae, 
further agreeing with Phigalia and a few others of the Riston group, and disagreeing with Alsophila, in the 
spinose abdomen and the non-anastomosis (or incomplete anastomosis) of the costal vein of the hindwing. 
Alsophila is exclusively Plolarctic. 
A. pometaria Pharr. (= restituens Walk., autumnata Pack.) (1 a). The is recognizable at once by pometaria. 
the formation of the postmedian line of the fore wing as well as by the structural characters; it has rather 
more rounded forewing, and of a somewhat deeper tone, than the Palaearctic aescularia and japonensis. The 
9 has the anal tuft less developed than in its European relatives. It is only too well known in Canada and 
the United States, its larva (the “Fall Cankerworm” of American economic entomology) often causing serious 
damage in orchards as well as to shade trees. The moth generally emerges about October, but continues to 
appear in mild weather in the winter and even in early spring. 
2. Genus : Cortixa Schaus 
Build slender. Pace protuberant, smooth. Palpus short. Antenna of $ minutely ciliated. Hindtibia 
with a single pair of spurs. Forewing with the 1st and 2nd subcostals stalked, 1st radial separate at its origin 
from 3rd—5th subcostals, 2nd radial normal, 1st median separate. Hindwing with costal free, somewhat 
approximated to subcostal about the middle of the cell, 2nd subcostal connate with 1st radial, 2nd radial 
slight, scarcely more than a fold, 1st median separate. One species. As with Caenosynteles in the Brephinae, 
we leave this genus in an evidently inaccurate position until some light is obtained on its taxonomy. 
C. aurudaria Schaus. Golden yellow above and beneath, the forewing with costal margin black and aurudaria. 
hindmargin grey above, yellow beneath; fringes black, tipped with grey. “Peru”, without exact locality, only 
the type known. 
3. Genus: Zanclojiieryx H.-Sch. 
Face smooth. Palpus moderate or rather long. Antenna long, in the $ with fascicles of cilia. Legs 
rather long and slender, the hindtibia with a single pair of short spurs. Wings white, thinly and smoothly 
scaled. Fore wing with apex acute, sometimes falcate; subcostal venation somewhat variable, but differing 
from that of the old-world Derambila in that the 1st subcostal arises from the costal. Hindwing with the 
costal closely approximated to the subcostal for a short distance near the base, the 2nd subcostal stalked 
with the 1st radial, the 1st median well separate. Early stages unknown. A small genus, ranging from Mexico 
to Brazil and evidently closely related to Derambila. 
Z. conspersa Warr. Less white than any other Zanclopteryx, the wings densely dusted with dark conspersa. 
fuscous; apex of forewing, even in the strongly falcate, postmedian curved, not oblique; median of hind¬ 
wing strong, slightly curved inward. S.E. Brazil. 
Z. aculeataria H.-Sch. (1 b), the type of the genus, was figured from a 9 and is represented with ex- aculca- 
tremely falcate fore wing, but the only known species for which it can be intended is the well-known one from tana. 
S.E. Brazil here figured. The 9 ? known to me are only a little more acuminate-winged than the <SS- In this 
species the antennal cilia arise from short pectinations. 
Z. mexicana Prout (lb). Generally rather smaller than aculeataria, the brown irroration a little mexicana. 
stronger, the markings weaker, the postmedian often marked with dots on the veins; the continuous terminal 
line of aculeataria is replaced by interneural dots and the fringe is whiter. Antennal pectinations of $ quite 
rudimentary. Central America, Trinidad, Venezuela and Ecuador; perhaps also in E. Bolivia. 
Z„ pundiferata Prout. Again smaller (20 mm), the white wings only faintly speckled with brown distallv. puncti- 
Fore wing with antemedian line wanting, the oblique postmedian consisting of light grey-brown spots on the fcrata. 
veins from 5th subcostal to 2nd submedian, the anterior one small, the succeeding ones forming a slight 
outward curve, the one on SM 2 diffuse, at about 3 / 5 ; cell dot rather larger; termen and fringe as in mexicana. 
Hindwing similar, but with two lines of vein-dots. “Santa Marta” (Bouchard). I was informed that this Santa 
Marta was in Brazil, but now believe it is the wellknown locality on the X. Coast of Colombia. Unfortunately 
confirmatory material is wanting, the type 9> with markedly acute apex, remaining unique. 
Z. uniferata Walk. (1 b) is the most widely distributed species. As large as aculeataria , but plain white uniferata. 
with blackish costal edge and fine terminal line; the veins only appear blackish in rubbed specimens. Known 
from Panama, the Bahamas, Jamaica, Venezuela and the Guianas, Colombia to Bolivia, Paraguay and S.E. 
Brazil. Walkers’ type was from the Amazons (Ega).
