places in the daytime have generally gray or blackish, protectively col¬ 
ored primaries, of such neutral tints as to deceive the eye in passing rap¬ 
idly over an extended surface. But in Apatela the direction of the 
mimicry, the object copied, differs in the larva and moth of the same 
species. The independent direction of the larval efforts in this respect 
is important evidence in sustaining the view that in metamorphosis the 
stages acquire characters useless to the succeeding, and that here the 
larva 0 {Apatela has attained an* independent perfection as regards ulti¬ 
mate peculiarities of adaptive structure applicable only to the conditions 
of its own particular'stage. 
CORRECTION OF THE TYPE OF AGRONOMA AND 
NOTE ON LASPEYRIA. 
By A. Radcliffe Grote, A. M. 
It has been recently stated by Mr. John B. Smith that the type of 
Agronoma , given by me in the Bremen List, May, 1895, P- 2 3 > viz: 
vestigialis, does not correspond in structure with jaculifera , the type of 
Feltia , inasmuch as the front is not roughened or tuberculate and the 
front pair of tibiae are not heavily armed. Still my reference of Feltia 
to Agronoma will hold. The material examined by me in Bremen in 
1893-4, when writing the list, is no longer accessible to me* and I am 
not sure what species I examined. But Hiibner’s genus Agronoma con¬ 
tains, beside vestigialis , both crassa and exclamationis . I have ex¬ 
amined here, in the Roemer Museum, specimen of crassa. The fore 
tibiae are heavily armed, the front is roughened or tuberculate, the male 
antennae are pectinate. It is therefore a Feltia. Inasmuch as vestigi¬ 
alis is referred as belonging to Agrotis in a restricted sense, and as 
congeneric with the type segetum , as established by me and adopted 
by me in the “Revision,” it follows that the type of Agronoma 
must be changed and crassa , the first species cited, is then the type. 
Hiibner establishes Agronoma for species having the general aspect of 
jaculifera ; the claviform is usually suffused with a darker color. Proba- 
bly the European species exclamationis , corticea, obesa , graslini and 
fatidua belong to Agronoma and share the structure of crassa. The 
name of our common North American species will then remain, as 
claimed by me in the list: Agrotis ( Agronoma) jaculifera Gn. Those 
using my Bremen List will please make the correction and I am much
