over the discal cross vein to the first m. nervule; this band is thrice regularly scalloped outwardly between the ner- 

 vules and includes a white discal dot on the cross vein, situate just below the inception of the discocellular nervule; 

 secondly, more narrowly and nearer the apices, the scales forming an even band extending downward to first median 

 nervule at a point where the usual transverse line crosses the nervule. This transverse line is narrow and distinct, 

 whitish, and is rounded at costa, not oblique and even, and joins the costal edge at a point considerably removed from 

 the apex. The ground color of the median space is a frosted purplish brown, over which the dark costal scales down 

 wardly intrude as above described. The dark scales extend again broadly and more aiffusedly downward from the 

 apex, bordering the transverse line externally and irregularly, widening over the median nervules to internal margin, 

 and leaving the irregular terminal space of the wing of a pale frosted purplish brown, over which the nervules are marked 

 with ochre. 



Secondaries full and rounded. At base thickly clothed with long and very bright ochreous scales. A large black 

 discal ocellus consisting of a broad blackish annulus surrounding a paler center, which contains a black pupil (the discal 

 spot) containing a few white scales. Outside this ocelloid spot are two broad subequal even blackish bands, the outer 

 the broader, and which traverse the wing from costa to internal margin . The pale dull ground color of the wing separates 

 these bands and obtains beyond the outer band, while the even narrow terminal space is concolorous with that on 

 primaries, being purplish brown, frosted, with pale scales, the nervules marked with ochreous. 



Beneath of a clear pale purplish brown. On the primaries the discal mark is seen and a blackish shade band indi- 

 cates the narrow transverse line of the upper surface. Secondaries concolorous with primaries; there is a distinct 

 white discal spot on the cross vein and a faint oblique dark shade band. The ground color of the wings has something 

 of a dead pink tinge beneath; this is especially noticeable on the secondaries below the median nervure. The exerted 

 veins on both wings beneath are covered with ochreous brown scales. 



Length of primary wing (from base to apical angle), 73 mil. Length of body, 44 mil. Width of primary (from 

 apex to internal angle), 50 mil. Length of primary (from base to internal angle), 44 mil. 



This fine addition to our United States faima differs from an allied tropical species determined as "egeus, Cramer 

 sp." in the Berlin Museum, in the shape of the primaries which in that species are produced at apices, the external 

 margin receding suddenly below them. It is also a rather larger, broader-winged, and slighter-bodied species. The 

 narrow whitish transverse line of the primaries is inwardly rounded superiorly to eosta. Hyp. zelleri is also distinguished 

 by the outer rounded band of the secondaries above, being even along its external edge, whereas in "egeus" it ia 

 prominently scalloped; this latter character will also separate it from a more Southern form recently figured by Dr. 

 Felder, who showed us his drawing while we were in Vienna. 



Dedicated to Prof. P. C. Zeller, of Meseritz, the widely known and respected entomologist, whose writings on our 

 subject need no mention of our earnest appreciation to enhance the value of his scientific labors. This dedication 

 commemorates pleasant days we recently enjoyed with the professor at his home, during which our science was dis- 

 cussed with one of its fathers whose personal kindness and consideration to us merits our thankful recognition.]

AUTOMERIS CORESUS (Boisduval).

Larva. — Last stage: Length, 85 mm.; width of head, 6 mm. Closely similar to that of 

 A. illustris in shape, general color and armature, and the lateral lines and colors of the ab- 

 dominal legs. It differs only in the red spiracles being much smaller; in the lack of the abun- 

 dant long white hairs, while the abdominal legs are less dark and red. 



The armature of spines (tubercles) is almost identical; the spines and the long, slender 

 spinules are well developed, pale straw-yellow, and of the same length and thickness as in A. 

 illustris. The double dark brown lateral line incloses a yellowish one. There is a similar row 

 of seven dark oblong patches on each underside of abdominal segments 2 to 8, each patch 

 bearing yellowish granulations varying in size. On each side of abdominal segments 2 to 7 is 

 a subdorsal row of six reddish-brown roundish spots, each situated between the dorsal and 

 supraspiracular spines. On the outer side of the anal and also the other abdominal legs is a 

 reddish patch, with pale or yellowish granulations. It is a very conspicuously marked larva, 

 the bright red spots contrasting with the hue of the body. 



Stage before the last: Length, 50 mm.; width of head, 5£ mm. 



Differs from the full-grown larva only in the tuft-like spines having the spinules a little 

 more spreading, but they are of the same relative length, thickness, and number.
