Mr. A. G. Butler on the Genus Entomogramma. 43 
Described from two male specimens, one darker than the 
other, and differing also in the number of joints of the 
antenne, but in no other particulars. C. scutellata is very 
similar in form and structure, but the antenne are only ten- 
jointed, not cyathiform, and the three terminal joints are much 
less distinctly separated than in C. cyathiformis. 
XII.—Notes on the Genus Entomogramma as_ represented 
by the Noctuid Moths of that Group in the Collection of the 
British Museum. By Axrtuur G. Burier, F.L.S., 
BZ.S., Se. 
WHEN he founded the genus Entomogramma, M. Guenée 
separated the species under distinct groups in consequence 
of their different antennal structure; indeed, no two species 
of the genus as originally constituted are quite alike in 
their male characters, and one of them was considered by 
Mr. Moore to be so dissimilar that he made it the type of a 
new genus. The latter, however, has no higher claim than 
the others to be so distinguished ; and as it would be neces- 
sary for the sake of consistency to found a separate genus for 
every species of the original group, provided that the secon- 
dary sexual characters were taken into account, it seems 
preferable to regard them, as Guenée did, merely as sections 
of one variable genus. 
The practical common sense of this mode of procedure 
being adinitted, Mr. Hampson has called my attention to the 
fact that various other species, differing only from typical 
Entomogramma (in the variability of the same organs in the 
male sex) in a similar though somewhat different manner, 
have been wrongly described in the genera Zhermesia, Phurys, 
&e. By adding these to Hntomogramma I find that a tole- 
rably gradational series is formed, evidently related throughout. 
The species of Hntomogramma in the Museum series thus 
resolve themselves into eight sections, each of which differs 
somewhat from all the others in its male structure, whilst 
that of the female remains almost the same, excepting in the 
case of section g, where the female is the modified sex. 
These sections will now stand as follows :— 
ENTOMOGRAMMA, Guen. 
Section a. TARAMINA, Moore. 
Males with basal third of antenne dilated, outer two thirds
