REVIEW OF SOME SPECIES OF LOXOSTEGE HUBNER 
AND DESCRIPTIONS OF NEW SPECIES 
(LEPIDOPTERA, PYRAUSTIDAE: PYRAUSTINAE) 
By Haun W. Capps! 
The purpose of this paper is to provide means for reliable identifi- 
cation of the species of Lozostege Hiibner, to correct invalid synonymy 
and nomenclature, and to provide names for undescribed species. 
Some nomenclature, following Hampson’s (1899, p. 207) error in 
treating Lozostege as a nomen nudum and synonym of Phlyctaenodes 
Guenée (1864, p. 173), needs correction. Although Hampson (1918, 
p. 189) corrected the error, the generic placement has not been cor- 
rected for those new species described in the interim from Mexico, 
Central and South America because there has been no subsequent 
revision involving them and because lists of American Lepidoptera 
published in that period have been restricted to North American 
species. 
In addition to the nomenclatural aspect, zoology is also involved. 
The type-species of Lozostege and Phlyctaenodes are not congeneric. 
Pyralis aeruginalis Hiibner, the type of Loxostege (Hampson, 1918, 
p. 189), differs from Pyralis pustulalis Hiibner, the type of Phlyctae- 
nodes (Hampson, 1899, p. 211), in maculation and genitalia as indi- 
cated below.
