Distribution of the Genus Anomis, Hiibner. 251 
from Abyssinia, involuta from Ceylon, and dona from Roe- 
bourne, W. Australia ; but there are distinct differences, and 
to my mind it is impossible to believe that localities that 
could not have had any connexion with each other for many 
hundreds of millions of years could possibly contain one and 
the same species of Noctuid, which is not migratory, and the 
larva and pupa of which could not have been carried by any 
commercial agency. 
“The study of the genitalia of Lepidoptera is still in its 
infancy. It may well be that forms of construction overlap 
and resemble one another in species far apart in detail and 
far apart in origin. But this remains to be proved. When 
one bears in mind cases like those of the genus Tephrosia 
biundularia and erepusculata, in which the genitalia differ, as 
far as has been discovered, only in the forms of a few names, 
or in Xy/ophasia, where the three recognized species—mono- 
glypha, sublustris, and lithoxylea,—in which the difference 
appears to lie in the number of certain hairs; or, again, when 
one remembers the number of spines which cannot be sepa- 
rated by the eye, but possess well-marked differences in the 
genitalia, such as the nzcti/ans group of Hydrecta, and the 
Acronicta’s, tridens and pst, it may well be that further study 
is necessary to learn the exact bearing of the genitalia upon 
classification. Any way, it does not so far appear to have 
presented greater uncertainty than have other lines of 
examination.” (Burrows.) 
General Facies of Anomis and Cosmophila. 
Valves delicate, sometimes weakly armed, margins gene- 
rally ragged. Coremata on ninth abdominal segment attached 
dorsally to the tegumental ring, and also to the valves, ex- 
tremely extensile and voluminous. Juxta * usually strongly 
developed. Scaphium generally present, tip minutely bifid, 
generally with tuft of long hairs ventral on eighth abdominal 
segment, connected with strongly developed segmental divi- 
sions. Anellus strongly armed with minute spines, 
SECTION I. 
Juata absent. Anellus exposed. 
Anomis exacta, Hiibner. (PI. TX. fig. 1.) 
Valves narrow, angulated at mid-length, unarmed. 
* Juzxta (Pierce), a plate fused to the front of the anellus.
