PTEROGON JUANITA. Nov Sp 



(PLATE XIII, FIG. 6 J'.) 



Male. Expands 2 inches. 



Head and body olivaceous. 



Upper surface ; primaries, colour and markings much as in P. Clarkia:. 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 f>f 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. Oue example, Mus. Strecker. 



A larger species than P. Clarkia, and with primaries much narrower and more prolonged apically, resembling more, in this re- 

 spect, P. Gaura, Ab. & S., from which it difl'ers, 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 g'.) 



Expands If — 2 inches. 



Head and body above ashen ; thorax shaded with brown ; two rows of dark brown spots on abdomen ; 

 anal segment trifurcated ; antennfe 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 

 greyish. 



Under 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 Akhurs*^, of Brooklyn, N. Y., wiio raised a number of examples of this species from the lar- 

 v£e, 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, (^4?7i^je/o;:)si.s quinquefolia) ; 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 l)rief 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 Z)eida?nia. If, 

 however, the Russian Gorr/oniades* is to be retained in the same genus with CEnotherce, then certainly Inscriphim belongs there likewise, 

 as there can be no doubt that Inscriplum and Gorgoniadex are gencrically the same, at least as for 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 ; but in that sex both species have the antenn* 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 

 Bvstematists may place Gorgoniades, there also Inscriplum belongs.
