NOVTTATES ZOOLOOICAE XXV. 1918. 409 



DC long, DC'~' somewhat curved, SC"'''''^ stalked, R' from before centre of 

 DC, M' stalked (in caliginosa from just before end of cell, according to a MS. 



note of Warren's). Hindiving with cell nearly one-half, C approximated to 



SC, rather gradually diverging, R^ central or slightly before, M' stalked. Rather 

 variable in length of palpus, size of eye, and some other characters, and needing 

 more thorough revision ; perhaps intergrades with Polypoetes in one du'ection 

 and with Dioptis in another.

* Cells shorter in chloris, though Warren's " chloris " was a misidentification ; see Hadesina 

 caerulescens Schaus. 



■f Tilhraustes latialbata sp. nov. 2. 27 mm. Closely akin to erymas Druce (possibly the same 

 as nervosus H. Edw., which is unknown to me). Palpus whitish, not orange. Antennal pectina- 

 tions apparently shorter (damaged). 



Forewing with termen less oblique ; veins more orange ; white band broader. 3'5 to 4 mm. 



Hindwing more broadly suffused at abdominal margin, the suffusion reaching the cell. Alpayacu, 



Rio Pastaza, E. Ecuador, 3,(100 £t. (M. G. Palmer). Type in coll. Joioey.
