NEOTROPICAL MICROLEPIDOPTERA, III — CLARKE 79 



Described from unique male type. 



This specimen, among others, was sent to Meyrick for determina- 

 tion, presumably by Busck. Attached to it is a note in Meyrick's 

 handwriting which reads: "Sent as second specimen of H. melobaphes 

 with ocherous h.w., but is new, I tlierefore return, h.w. of melo- 

 ba2)hes vary from ocherous to dark fuscous, but never white." I 

 would not describe the hindwing of this specimen as white but it is 

 certainly lighter than that of any of the other species considered here. 



There is some doubt in my mind about placing periphereia in Gonio- 

 nota. Although the genitalia are not dissimilar to those of other 

 species associated with melobaphes and the venation easily permits 

 its retention here, the fact remains that the labial palpus of periphereia 

 differs from those of the other species. Moreover, the third segment 

 is short, about one-third the length of the second, and devoid of any 

 long scaling on the posterior edge. Finally, this is the only species 

 lacking the eversible tuft from the first sternum, but this can, and 

 may, be only a specific character.

Labial palpus ocherous white overlaid with brown, especially on 

 outer side of second segment, sparsely irrorate with fuscous and red- 

 dish ocherous; third segment similarly colored, apex whitish. An- 

 tenna ocherous white ventrally, grayish fuscous dorsally. Head 

 buff yellow mixed with brown and reddish ocherous. Thorax ocher- 

 ous mixed with brown; tegula brown basally. Forewing ground color 

 light brown shaded with fuscous costad and with a faint violaceous 

 tinge in tornal area; basal patch buff yellow mixed with reddish ocher- 

 ous, extending to two-fifths; costal margin of basal patch broadly 

 edged with ground color for nearly its entire length; in cell, at outer 

 edge of basal patch, a blackish spot; several reddish ocherous blotches 

 in center of wing; at apical thh'd costa excised, bordered white; around 

 termen a series of white scale patches preceded by ill-defined fuscous 

 spots; dorsal margin edged with fuscous and with a group of blackish 

 scales at base of dorsum. Hind wing ocherous white shading to 

 brownish ocherous apically; in anal area scattered fuscous scales; 

 cUia grayish fuscous, paler basally. Legs ocherous white lightly in- 

 fuscated; tarsi white with a few fuscous spots. Abdomen brownish 

 dorsally, ocherous white ventrally. 



Female genitalia: Ostium broad, crescentic. Posterior two-fifths 

 of ductus bursae sclerotized and bent anteriorly; inception of ductus 

 seminalis dorsal, near junction of membranous and sclerotized parts of 

 ductus bursae. Signum a small, bilobed, sclerotized dentate plate.
