 both edges finely margined with white, most marked on the outer edge beyond 

 cell ; marginal area edged by deeper lunules below middle, above it .swelling out 

 into a large triangular blotch, the apex of which all but touches the projection

151. Psaliodes tripita ab. corrosa uov. 



P. tripita was described by M. Dognin from a single cJ from Loja, Ecuador. 

 Of nine examples from Santo Domingo, S.E. Peru (four (?(?, five ? ¥ ), most 

 exhibit a marking not noted by him — viz., the filling up of the sjiace between 

 veins 3 and 4 of the forewing, as far as submargiual line, by a more or less 

 developed streak of pale scales ; the ¥ ? , which also have the hindwing darker 

 than the dS, are on the whole darker in the forewing and show this peculiarity 

 least; in the S S the streak is sometimes oclireous, sometimes whitish, and at 

 others orange, and generally veins 3 and 4 themselves, more rarely vein 2 as 

 well, are coloured similarly. In the c? example, to which I give the name corrosa, 

 this tendency is exaggerated ; here the whole space between veins 2 and 4, 

 as well as a slight distance above and below them, is filled with dull white scales 

 nearly reaching the hindmargin, obliterating all the markings, and at first giving 

 the impression of the wings having been rubbed. 



All the examples were taken between November I'.miI and .lanuary I0ii2 in 

 the wet season (Ockenden).
