ilTEliOGON JUANITA. Nov. Sp 
(PLATE XIK, FIG. 6 tf.) 
Male. Expands 2 inches. 
Head and body olivaceous. 
Upper surface ; primaries, colour and markings much as in P. Clarkice. Secondaries bright yellow, a 
reddish marginal band deepening into brown nearest the outer edge, broader than in P. Clarkice,) a reddish 
spot on abdominal margin towards anal angle. 
Under surface; inner half of wings reddish-brown, outer third pale olivaceous, darker towards margin; 
the basal part of primaries is more reddish than on secondaries. 
Habitat. Mexico or S. W. Texas on borders of the Rio Grande. One example, Mus. Strecker. 
A larger species than P. Clarkice , and with primaries much narrower and more prolonged apically, resembling more, in this re- 
spect, P. Gaurce, Ab. & S., from which it differs, however, in the colour of the hind wings, which are red, margined with black, in the 
latter species. I have seen but the one example which I have portrayed, I trust faithfully, on the annexed plate.

(PLATE XIII, FIG. 8 $.) 
Expands If — 2 inches. 
Head and body above ashen ; thorax shaded with brown ; tw r o rows of dark brown spots on abdomen ; 
anal segment trifurcated ; antennae serrated in male, plain in female. 
Upper surface. Primaries same colour as body, with bands and marks of rich brown of various shades ; 
a pale discal spot and a small white triangular spot near exterior margin. Secondaries reddish; outer margin 
r surface ashen, all wings outwardly, with darker colours ; the small triangular white spot on upper 
surface near outer edge of primaries is repeated. 
Habitat. Middle and New England States, Maryland, Virginia, Ohio, Indiana and doubtless other 
States east of the Mississippi, but nowhere common. 
Mr. John Akhurst, of Brooklyn, N. Y., who raised a number of examples of this species from the lar- 
vae, describes it as being, when full grown, two inches in length, of a fine green colour, caudal horn whitish 
at the tip, head small, body from third segment tapers towards the head. It feeds on the leaves of the grape, 
and of the Virginia creeper, (Ampelopsis guinquefolia ) ; to undergo its transformation it enters the ground, 
but not very deep ; it is frequently found near the side of a wall or the bottom of a fence post, and even under 
a_ board or flat stone ; it is full grown about the last of June, or beginning of July, and is single brooded, the 
perfect insect appearing about the middle of May. Mr. Akhurst made neither notes nor drawings at the time, 
but the above, though brief and lacking in details, in consequence of his having to depend entirely on memory, 
he is sure is substantially correct. 
Harris provisionally placed this species in Pterogon ; Dr. Clemens afterwards made for its reception the genus Deidamia. If, 
however, the (Russian Gorgoniades* is to be retained in the same genus with (Enotherce, then certainly Inscriptum belongs there likewise, 
as there can be no doubt that Inscriptum and Gorgoniades are genetically the same, at least as far as comparisons between the males 
extend. Whether the $ of Gorgoniades has simple antennae like that sex in Inscriptum I can not now say, as I have seen only males of 
the former; hut in that sex both species have the antennse serrated, the eyes sunken, the head produced in a crest, the shape of thorax 
and abdomen the same, the anal segment trifurcated, and the same style of ornamentation on wings and body; and in whatever genus 
systematists may place Gorgoniades, there also Inscriptum belongs.
