412 NOVITAIBS ZOOLOOICAE XXV. 1918. 



Genus XV. Phryganidia. 



Phryganidia Pack., Proo. Ent. Soc. Philad. iii. 348 (1864) (tj-pe cali/omica Pack.). 



Structurally nearest to Section I of Polypoetes, scaling thinner and more 

 hairy, cells rather longer. The only Nearctic genus of the family. The early 

 stages have been rather carefully studied ; see Stretch, III. Zygaen. N. Amer. 

 91 ; Dyar, Journ. N.Y. Ent. Soc. iii. 21; Packard, ibid. 32-34; Kellogg and 

 Jack, Proc. Calif. Acad. Sci. (2) v. 562. A second species, with narrower wings 

 and R' of forewing stalked, is here rather doubtfully added. It is curious that 

 both have been quite independently referred to the Psychidae !

2. naxa Druce, Biol. Centr. Amer., Lep. Het. i. 229 (1887) (Typhonia) (Guate- 

 mala ; Panama). 



Genu.s XVI. Momonipta. 



Stenoplastis Feld., Reise Novara, Lep. Het. tab. 105. fig. 16, Erkl. p. 9 (iiidescr.) (type satyroides Feld.). 

 Momonipta Warr., Nov. Zool. iv. 421 (1897) (type albiplaga Warr.). 



Head not large. Eye moderate or small. Face more or less hairy. Palpus 

 shortish to moderate, second joint rough to hairy beneath, thnd joint small. 

 Antenna in S with fascicles of cilia. Pectus moderately hairy. Femora some- 

 times hairy. Abdomen rather slender. Wings fairly broad. 



Forewing with cell rather less than one-half, DC moderate to long, 

 gQ2,5,3, 4 gtalked, R' from before middle of DC (much before in type species). 

 Hindwing with DC strongly oblique, R' central, M' stalked. 



As at present constituted, the genus only differs positively from Polypoetes 

 in the ciliate 3 antenna, but the vestiture becomes progressively more hairy, 

 and it may jjrove possible to constitute a new genus for the species with hairy 

 femora.

* Momonipta empheres sp. nov. (J, 30 mm. Similar to jipiro as figured by Dognin, Lep. Loja, 

 tab. 9. fig. 13 (unkno\TO to me in nature), possibly a form of it (aberration or subspecies). Differs 

 on the /orewing. in having a yellow- white spot at base of M. SM' and S.\P, vaguer and more extended 

 white marking in cell, white abdominal margin from close to base to beyond middle, narrower 

 spot outside DC, a small yellow, white-mixed spot at branching of SC'i *■ ' ; hindtcing with the black 

 border narrower posteriorly. Santo Domingo, S.E. Peru, 0,000 ft. (G. Ockenden) : November 

 1904, type in coll. Joicey ; October 1902, paratype in coll. Tring Mus. Differs from typical 

 Momonipta in less Jiairy face and larger eye.
