Hind wings pink on the costal region, with no definite lines; outer edge and posterior half 

 colored as in the middle of the hinder part of the fore wings. 



Under side of fore wings half pink toward the inner edge; costa with brown spots and a 

 sinuous row of five isolated irregular distinct lunate dark reddish-brown spots on the outer 

 fourth of the wing; the wing along the scalloped outer edge is deep vandyke brown. Hind 

 wings coarsely mottled with reddish brown and lilac; an irregular extradiscal line of lunate 

 brown spots. 



The female is very different in its shape, size, color, and markings. It differs from the 

 cf in its much larger size, in its antennae having but a single pair of pectinations to a joint, 

 and in its much less falcate wings and uniform dark-brown hue, which is a peculiar dark ash- 

 brown, the color of a very dark dead leaf; the fore wings are not so falcate and the outer edge 

 not so deeply hollowed out as in M. herilla 9 . 



Fore wings with no reddish scales except toward the apical region. A black-brown zigzag 

 basal line situated rather far from the base of the wing, the most distinct angle lying in the 

 discal cell. Extradiscal line parallel to, but far from the outer edge and bent back at a right 

 angle on the costa. 



Hind wings concolorous with those of the .anterior pair; no lines, but a very large roundish 

 cream-white spot on the inner half, not reaching the costal or the inner edge. No discal spots 

 on either wing. 



Under side of fore wings as dark as above; extradiscal line distinct and interrupted by an 

 irregular large elongated cream-white spot; along the inner edge is a wide deep pink area. 

 Hind wings as above but more reddish-ash, the white spot as above. As this species has retained 

 the two lines on the fore wings, it seems to be a more primitive species than M. herilla, in which 

 they are obsolete. 



Expanse of fore wings, d 70 mm.; 9 86 mm. 

 Length of one fore wing, d 35 mm.; 9 42 mm: 

 Breadth of one fore wing, c? 11 mm.; 9 21 mm. 

 Length of a hind wing, <? 22 mm.; 9 30 mm. 

 Breadth of a hind wing, <? IS mm.; 9 21 mm. 



This, like M. herilla, is very obviously protective in the form, colors, and outline of the 

 wings, and shows a remarkable resemblance to a dead, torn leaf. 



Subfamily 5. Etjd^emoniusle Packard. 

 [Endsemoniinx, Packard, Psyche, February, 1902, p. 306.] 



An aberrant group not improbably of full family rank, perhaps belonging after Cyrto- 

 goninse, or near Urotinse. The single genus is remarkable for the excessively long tails of the 

 hind wings, the long slender palpi, the end of the second joint extending just beyond the front, 

 and the third joint very long; and the venation. Head in front squarish; when denuded of 

 scales flat, scarcely narrowing in front. Antennas of <? with but a single pair of pectinations 

 to each joint. Maxillae very slender, not united, but nearly half as long as the palpi. Fore 

 wings short and broad. Hind wings small, triangular, the tail being from three ( 9 ) to five 

 times ( 6") longer than the main portion of the wing. Venation approaching that of TJrota; 10 

 veins in the fore wings, only 7 in the hind ones. The venation of the wings of the hinder pair 

 is evidently affected by the great development of the "tail," which is strengthened by the three 

 veins (III 3 , TV,, IV 2 ), no vein V (internal) detected. The discal veins ("discocellulars") very 

 unlike that of TJrota or any other genus, and together forming a very oblique, bent, or angulated 

 line. The body is slender; the legs long and slender; the fore-tibial epiphysis rather long and 

 about two-thirds as long as the tibia itself; the abdomen slender, that of the 9 clothed at the 

 end with a large singular mop-like mass of dense, short battledoor-like scales, with a lateral 

 tuft on each side. 



The o* genitalia show some remarkable features which we have not met with in this or 

 allied families. While the claspers are in the main like those of Sphingicampa, etc., the suranal
