 Suppl. Catal. Blatt., p. 3. 



"Male. Piceous. Head black; clypeus, palpi and antennse red. 

 Prothorax scabrous, transversely elliptical; anterior half of the border 

 red; some longitudinal impressed lines in the disk. Pectus, legs, sides 

 of the abdomen and hind borders of the segments tawny; femora 

 setose beneath. Fore wings extending for full half the length beyond 

 the abdomen, with numerous minute pale testaceous dots, occasionally 

 with a large pale testaceous patch in the disk near the base. Hind 

 wings pellucid ; veins paler. Length of the body 8-9 lines ; expansion 

 of the fore wings 28-30 lines. The prothorax is regularly elliptical, 

 and thus differs from that of P. Mexicana, in which the hind part is 

 broader than the fore part, and is truncated on each side. a-b. South 

 Mexico." 



This is apparently a member of the genus Homceogamia, but cannot 

 be positively identified. It is possibly a synonym of mexicana, as 

 Walker's knowledge of the latter species must have been limited, as 

 his statement regarding the form of the pronotum in that species is 

 partially erroneous.

"Un seul exemplaire a I'etat de larve. 



"Possedant dans ma collection des individus a divers-degres de 

 developement, je pens affirmer seulement que cette espece ne se rapport 

 pas a H. mexicana Burm., avec qui je I'ai comparee, ni a H. hrasiliana 

 Sauss., bien que cette derniere espece ait ete decrite sur un male a 

 I'etat de nymphe. Le pronotum est convert de granulations mili- 

 aires, ses sillons dorsaux etant remplaces par de simple depressions, 

 ce qui donne a I'insecte un facies un pen different des autres Homceo- 

 gamia. — Caracas. 



" Je crois cette espece nouvelle, mais ne possedant pas des individus 

 bien developpes, je ne la decris pas."
