PHOEDINUS. 335 



PHCEDINUS, gen. nov. 



Allied to Thorybes, and the male, as in that genus, without a costal fold to the 

 primaries; the terminal joint of the palpi is much longer and more prominent, being 

 distinctly porrect, the hook of the antennae is shorter, the third median segment of the 

 primaries relatively shorter, and the lower discocellular longer. 



The range of the genus extends from Southern Arizona to the highlands of Guatemala.

Alis saturate brunneis ; anticis maculis octo semihyalinis, una transversa cellulari, una rami mediani secundi 

 utrinque, una ultra eas, et quatuor subapicalibus ; anticis ciliis fuscis inter venas pallidioribus, posticis 

 ciliis albis ad angulum apicalem fuscis : subtus pallidioribus, anticis ad marginem externum, posticis undique 

 lineis nigris vermiculatis ; posticis quoque fasciis duabus indistinctis fusco-nigricantibus notatis : palpis 

 albicantibus squamis fuscis intermixtis, segmento ultimo nigro. 



Hab. Noeth America, Arizona 1 . — Mexico, Northern Sonora {Morrison), Orizaba 

 (H. J. Elwes), Acaguizotla {H. H. Smith) ; Guatemala (mus. Staudinger), Polochic 

 Valley {F. B. G. & 0. S.), Duerlas {Champion). 



Dr. Staudinger has kindly lent us a specimen of this species which bears the name 

 Eudamus caicus, H.-S., with the type of which it has doubtless been compared. It 

 agrees with a series of examples we possess from Guatemala and Southern Mexico ; but 

 those from our north-western frontier are rather paler, the palpi are whiter, and the 

 hyaline spots of the primaries are larger. The latter probably belong to Mr. Edwards's 

 Eudamus moschus from Arizona. We hesitate to separate them from the darker 

 more southern forms, especially as the male genitalia do not differ in any way. 



These have a short cleft tegumen, the harpes have rounded ends, and there appears 

 to be no distinct fissure on the dorsal edge. (See Tab. LXXX. fig. 20.) The imago 

 figured is from Orizaba. 



2. Phoedinus aventinus, sp. n. (Tab. LXXX. figg. 21, 22.) 



P. caico aliquot similis, sed posticis longioribus magis productis, ciliis omnino fuscis ; maculis anticarum 

 parvis et magis numerosis, macula cellulari et ea infra cellulam bifidis, altera quoque costali supra 

 cellulam : subtus omnino unicoloribus, posticis vix fasciatis : palpis obscure griseis. 



Hab. Mexico, Dos Arroyos and La Venta in Guerrero (H. H. Smith). 



Having only two specimens of this species, we are in some doubt as to the propriety 

 of assigning them to this genus. They are apparently males, and having no costal 

 fold to the primaries agree with Phoedinus caicus, and the palpi are also elongated. 

 The secondaries are longer and resemble those of Cogia calchas, but there is no trace 

 of a pencil of hairs near the inner margin of the secondaries. The types were captured 

 by Mr. Herbert Smith in the month of September in Guerrero, at elevations of 300 

 and 1000 feet above sea-level.
