634 MR. W. SCHAUS ON WALKER'S [June 16, 
On Walker’s American Types of Lepidoptera in the Oxford 
University Museum. By W. Scuavs, F.Z.S. 
The following notes on Walker’s American types in the Oxford 
University Museum are to be foliowed by others, wherein the 
complete synonymy will be given of many of the species, and 
references will also be made to those species which as yet remain 
unidentified. My special thanks are due to Prof. E. B. Poulton, 
F.R.S., for the trouble he took in selecting the American Moths 
from the Hope Collection, and sending them family by family to 
the British Museum to be compared with the collections there and 
with my own collection; and to Mr. G. F. Hampson for his 
untiring kindness and assistance. Those species marked with an 
asterisk are represented in my own collection ; those of which I do 
not possess specimens, and which are not in the British Museum 
either, have been figured in duplicate, one set of figures being 
placed in the Entomological Department of that Museum. The 
species described by Walker in parts 27-30 of his Catalogue, and 
in the corresponding portions of the Supplement, as being in 
“Coll. Saunders ” never formed part of the Hope Collection of the 
Oxford Museum, but have lately been purchased by the British 
Museum, where the types are now to be found. 
The references given refer to Walker’s ‘ List of the Specimens of 
Lepidopterous Insects in the Collection of the British Museum,’ 
Vou. II. 
P. 775. *Norape puella described from the Fry coll. is now in the 
Saunders coll., and is the same as Archylus pectoral, 
Walk. 
Von. IV. 
P. 801. Sarsina purpurascens. I have not yet been able to find 
the type. 
P. 895. *Darala falcata=Lonomia submacula, Walk. 
P. 957. Lsychagrapha floccosa. Not identified. 
Vou. V. 
P. 1046. *Naprepa camelinerdes is a distinct species belonging to 
the Notodontide. 
P.1115. Laruma heterogenea is a distinct species, the genus 
being the same as Hydrias. 
P. 1152. Nesara apicalis belongs to the genus Ocha, Walk. 
P. 1155. *Pamea excavata and Pamea notata are the sexes of one 
species. 
P. 1155. *Pamea vittata belongs to the genus Carthara, Walk. 
P. 1170. osema deolis is not Cramer’s species, and I therefore 
propose the name of &. walkeri for it ; the species is 
well described by Walker.
