4J4 NOVITATES ZOOLOQICAE XXV. 1918. 



Hindwing in type rather long : cell rather strongly produced posteriorly 



DC biangulate ; R' rather behmd middle, M' stalked. 



The $ is not certainly known and the genus may prove untenable — ^perhaps 

 a secondary sexual development of Tithraitsles.

 Also occurs in Bolivia.

Extends to S. Peru and Rio ; jrigida (unfortunately the older name) is 

 probably merely a unique aberration of the same.

Genus XVIII. Phanoptis gen. no v. 



Phanoptis Feld., Iteise Novara, Lep. Het. tab. 104. fig. 10. Erkl. p. 8 (indescr.) (type cyanomelas Feld.). 



Face with appressed scales. Palpus shortish, with dense but appressed 

 scaling. Antenna in both sexes pectinate, branches in ? quite short. Pectus 

 scarcely hairy. Femora not hairy. Wings elongate, hyaline (except in fatidica). 



Forewing with cell long, at end narrow, DC long; SC"''''-' stalked, M' 



widely separate. Hindwing with cell long ; C rather remote from SC, R' slender, 



M' widely separate. 



Here begins a group of hyaline-winged genera, reaching to Hadesina.

Mr. Joicey has a more heavily marked example from Guatemala, in addi- 

 tion to the normal Chiriqui form. Mr. Schaus collected the species in Costa Rica. 



Genus XIX. Authyala. 



Authyala Warr., Nov. Zool. .xii. 311 (1905) (type oUiquaria Warr.). 



Differs from Phanoptis chiefly in that M' of the forewing is almost connate 

 with R', not widely separate ; cells less narrowed distally. 

 1. obliquaria Warr., Nov. Zool. xii. 312 (1905) (Peru). 



* Teste Dognin in litt., August 12th, 1918. The name will have priority, but my proffered 

 determiaation is at present too precarious.
