PTEROGON JUANITA. xNov Sp 



(PLATE XIII, FIG. 6 c?.) 



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 hiind 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 retldish-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 witli priinarits 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, wliicli are red, margined with black, in the 

 lutter species. I have seen but the one example which I have portrayed, I trust faithfully, on the annexed plate.

(PLATE Xin, FIG. 8 J>.) 



Expands 1 J — 2 inches. 



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

 anal segment tril'urcated ; anteiiniB 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 8shet% all wings outwardly, with darker colours ; the small triangular white spot on upper 

 surface near outer edge of i)rimaries is repeated. 



Hal)itat. Middle antl New England States, Maryland, Virginia, Ohio, Indiana and doubtless other 

 States east of the Mississippi, but nowhere common. 



Mr. John Akhurst, of Brooklyn, X. 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, (ylH(^j(/ojj.'*/.s (/uini/uefolia) ; to undergo its transformation it enters the ground, 

 but not very deep ; it is fre(|ucntly found near the side of a wall or the bottom of a fence ])ost, and even under 

 a^ board or flat stone ; it is ftill 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, 

 lie 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 (jorfloniaJes* is to be retained in the same genus with QCtiothera, then certainly Inscriptum belongs there likewise, 

 as there can be no doubt that Inscriptuin and Gor<]oniades are generically the same, at least as far as comjiarisons between the males 

 extend. 'Wlullier the 9 "' Gorgoniades has simple antennae like that sex in Inscriptutn I can not now say, as I have seen only males of 

 the former; but in that sex boih sincies have the antenna' serrated, the eyes sunken, the head juoduccd in a crest, the .shape of thorax 

 and abdomen the .same, the anal segment trifurcaled, and the same style of ornamentation on wings and l)o<ly ; and in whatever genus 

 ^ystematists may place Gorgoniades, there also Inscriptwn belongs.
