wing, and they have the apical part of the antenna flattened, appear- 
ing to be clubbed in a lateral view. The corresponding markings of 
females are different in poey2, and the antenna is simple and filiform; 
in klagesi the length of the forewing of the male is 17 mm., that of the 
females 17 to 21 mm. 
Jordan described klagest from three females from Ciudad Bolivar, 
Orinoco [Ciudad Bolivar, Bolivar, Venezuela], July 1898, S. M. 
Klages. I select the specimen he illustrated, plate 11, figure 9, as the 
lectotype. The specimen is in the British Museum (Natural History) 
via the Rothschild collection and has been labeled as lectotype. 
Dyar’s original series of pulverosa was composed of one male and six 
female cotypes from La Chorrera, Panama. The specimens are in 
the collection of the U.S. National Museum. I have selected and 
labeled one of the females as the lectotype. The genitalia of the 
lectotype have been mounted on slide number 294 by J. G. Francle- 
mont, and the specimen is so labeled. 
E. klagesi Jordan is known mainly from the type localities. Jordan 
discusses a specimen from Guayaquil, Ecuador, that is either referable 
to this species or to walkeri tucumanus. It will be necessary to restudy 
the specimen to determine the correct placement. Two females from 
Pernambuco, Brazil, in the U.S. National Museum presumably belong 
to this species but differ slightly as the brown postmedial marking of 
the forewing does not extend as far basad as it does in the females 
from Panama and Venezuela. Obviously more material of klagesi is 
needed to determine its distribution and the extent of its individual 
and population variability. 
Euscirrhopterus walkeri Hampson 
Euschirropterus [sic] valkeri Hampson, 1901, Catalogue of the Lepidoptera Phalae- 
nae in the British Museum, vol. 3, pp. 619, 620, fig. 270.—Strand, 1912, 
Lepidopterorum catalogus, pt. 5, p. 28.—Draudt, 1919, in Seitz, Die Gross- 
Schmetterlinge der Erde, vol. 7, p. 4, pl. 1, row b.— Hampson, 1920, Catalogue 
of the Lepidoptera Phalaenae in the British Museum, Supplement, vol. 2, 
p. 583. 
Hampson obviously named this species after the collector of the 
type series, J. J. Walker, but he deliberately changed the “w” to a 
“vy” as was his usual practice in latinizing scientific names. He usually 
also changed “k”’ to “ce” but did not do so in this instance. Strand 
(1912, Lepidopterorum catalogus, pt. 5, p. 28) suggested that the name 
should be “walkeri.”” I agree with Strand and have emended the 
name accordingly. 
Typical walkeri is known to me only from the description and 
illustration of Hampson. The species was described from a male 
and female from Valparaiso, Chile. Hampson did not indicate 
which specimen was the type and noted no differences in size or
