MtTL ouis B. Prout on the 
most limit yet recorded ; northwards I am not able to 
indicate so precisely its known range, but it is certainly 
frequent in the eastern United States, and Packard 
(“ Monograph,” p. 335) gives several localities in Massachu¬ 
setts, etc., and one or two even in Maine. I formerly 
attempted to keep the more desh-coloured and the more 
greenish forms specifically distinct as msMfearm, Guen., and 
asthenaria. Walk., respectively, but I cannot find that the 
colour difference is even locally constant, except that I 
think all the southern ones belong to the green-tinted 
form (asthenaoHa). M. Dognin has furnished me with two 
records for Tucuman, one as Deptalia asthenaria. Walk., 
the other as Ptychopoda insulsaria, Guen., but I have no 
further note on the material in his collection. 
21. Dichromatopodia sigillata (Walker). 
Pyrinia sigillata. Walker, List Lep. Ins., xxvi, 1491 
(1862). 
Tucuman and Los Vasquez, in coll. Dognin. 
Walker’s type was from Santarem. 
22. Dichromatopodia concomitans (Warren). 
Dichromatopodia concomitans, Warren, Nov. ZooL, xiv, 207 
(1907). 
Tucuman, in coll. Rothschild (type) and in coll. Bastel- 
berger. 
23. Ptychopoda piperata (Warren) (?). 
Ptychopoda piperata, Warren, Nov. ZooL, viii, 456 (1901). 
Gran Chaco, near Florenzia, October 1902, in coll. Br. 
Mus. 
Warren’s types (^ and $) were from Sao Paolo, S.E, 
Brazil. They were missing from the boxes of types \vhen 
I studied these a few years ago; but the presence of topo- 
types in the British Museum collection and in that of 
Mr. E. Dukinfield Jones has enabled me to examine it, 
and to confirm Warren’s reference of it to the genus 
Ptychopoda. I am not absolutely certain that the Gran 
Chaco insect is specifically identical; its postmedian line 
on the forewing is somewhat incurved near the inner 
margin.
