HARRISON G. DYAR. 
Artaxa imjenita Hy. Edwards does not belong in tlie Cochlidia?, 
but is also referable to the Dasychirie.* 
.Moiioloii<>a snlMlciito$«a u. sp (Plate iv, fig. 21) 
Allied to M. semifascia (fig. 20). Thorax and primaries dark waliuit-hrown ; 
abdomen, secondaries and under side paler. A narrow, upright, zigzag, white 
line extends from the middle of internal margin to median vein, l>ut does not 
cross the vein nor extend on to the fringe as does the corresponding mark in 
semifascia. It is twice regularly augulated, more sharply externally. The space 
between this mark and the base of the wing is of a ferruginous brown, paler 
than the rest of the wing and narrowly separated from the white mark by the 
ground color. Expanse 22 mm. 
Type, one 9 > the collection of Mr. Graef 
The species of Monoleuca may be separated as follows : 
Transverse band upright. 
Baud white. 
Baud narrow, preceded by a ferruginous shade osa Dyar. 
Wider; wing coucolorous semifascia Walk. 
Band yellow siiltiirea Grote. 
Transverse baud oblique obliqiia Hy. Edw. 
Genus 1*AC'KARI>I.4 G. and R. 
This genus was characterized by Dr. Packard, in 1864, f as Cyrtosiu, 
but this name, being preoccupied, was sub.sequently changed by 
Grote and Robinson. 
The species are subject to considerable variation, and are usually 
rare. I have examined the male genitalia of three species and I 
cannot find that they offer any characters to afibrd specific separa- 
tion. The supra-anal plate in all narrows ra]fidly, and is extended 
backward in a long, evTii, narrow prolongation that slopes downward 
without curving, being pilose beneath. It resembles the same part 
in Datana, but is much less strongly bent down. The side pieces 
are simple, concave inwardly, slightly tapering, the ends rounded. 
The larvie are small green Limacodes, much resembling Parasa fra- 
terna in general shape, but lacking the spinose subdorsal tubercles, 
'fhe end of the body is ])roduced into a little “ tail” as in Parasa, 
which is often marked with red above, and this constitutes the only 
colored marking. They feed on the leaves of any deciduous tree, 
usually frequenting the central or more shaded parts of the woods. 
Only one brood occurs each year in New York, the larv’je maturing 
in September. 
Dr. Packard has kindly allowed me to see his material in this 
genus, and I believe the following arrangement of species corresponds 
with his opinion.
