16 Mr. A. G. Butler’s Descriptions of new 
wisely says, ‘“‘so far as I know” his words are “ Ks ist 
bis jetzt, so viel mir bekannt, noch Niemandem, selbst 
nicht einmal dem gelehrten Hrn. Grote, eingefallen, aus 
diesem individuellen Unterschieden der 7’. Luna Art- 
rechte herleiten zu wollen und diverse Species daraus 
zu bilden.” 
In the third place, supposing that the whole of Herr 
Maassen’s varieties are reared from the eges of the same 
female, and therefore can without hesitation be regarded 
as abnormally developed sports of the same species; it 
will be noticed that none of them appear to differ in the 
form of the primaries, the whole apparently possessing 
the extraordinary faleate character of JT. luna, since 
nothing to the contrary is noted. 
Lastly, the variability of one species in a genus is no 
certain guide by which to measure the constancy of the 
others; conditions of climate may readily develop 
aberrations in the one case which are quite unknown in 
the others; even the late Mr. Hewitson, whose tendency 
to associate allied forms is well known, saw fit at times 
to limit the variability of species to such an extent as to 
astonish his friends, some of his species of [thomia * and 
Pronophila + being distinguished by the coloration of the 
antenne, or the simple addition of a single white spot 
on the under surface. 
LASIOCAMPIDA. 
29. Hutricha dolosa, n. 8. 
3. Nearly allied to EH. pint; but altogether larger, 
duller, and darker; primaries greyish, the band just 
beyond the cell grey edged with black, of nearly equal 
width, excepting at the first median and lower radial 
branches, where it is abruptly constricted; the disc 
beyond this band dark ferruginous, with whitish external 
margin in the sinuations of the external border; the 
black spots bounding the external border internally very 
ill-defined; secondaries fuliginous-brown instead of 
mahogany-red; the costal area and outer margin 
greyish; the fringe blackish brown; body fuliginous- 
brown; under surface fuliginous-brown; the discoidal 
area of the primaries and an abbreviated streak beyond 
* As, for instance, J. linda. 
+ Compare P. poesia and P. proerna from Bogota.
