gray, light pea-green, faint purplish and peachy grounds, 
and dirty dim colours of various shades, &c. Not “pink, 
or flesh-tint.” 
Sth. On the central segments there is a well-defined 
spade-shaped mark, &c. Nota“ Y-shaped mark.” 
6th. I fail to find that each dorsal segment has four 
yellowish tubercles. 
7th. Spiracular line wavy, spiracles dark, with a distinct 
light ring round each. Not “ yellowish.” 
8th. Head very small, horn-like; corslet small, striate, &c. 
9th. Under side light, inclined to ashy green. Not 
* pinkish white.” 
10th. It feeds exclusively on Knautia arvensis. Not on 
“ling.” - 
Does Mr. Crewe like the reasons, now some of them are 
put before him? But, as I said before, lam not a speculative 
naturalist, and have no particular process of reasoning: I am 
guided by facts-alone; hence I am so little understood by 
people who sit at home and speculate, whilst I am burning 
oil on the moss, the moor, or upon the mountain; or they at 
best go out for a few hours in the sunshine, twiddling into an 
umbrella, or sit twaddling about the dreadful havoc ichneu- 
mons make with their larve; whereas, I take it, the death-rate 
amongst the few larve they can hope to beat off in the day- 
time is mostly caused by the injury they receive as they fall, 
or they are the sickly larve which could not hide away until 
feeding time. 
The tone of the second note (Entom. vii. 291) is such as to 
-preclude a lengthened reply from me. I will, however, show 
how utterly its logic fails when applied to both notes. In 
one case Mr. Crewe makes a Knautia-feeding species a heath- 
eater, though its food belongs to the natural order Dipsacezx, 
—three or four natural orders removed from the natural 
order “ Ericacez,” on which his heath-feeder lives,—yet he 
doubts the possibility of the other species eating the very 
next plant in the same genus to the one he, and I, have 
been told it feeds upon on the Continent. I recently saw a 
cabinet, twenty miles from here, which requires more drawers 
to contain the pugs therein than would accommodate all 
Mr. Crewe’s British Geometrine, pugs included; and yet, 
forsooth, we, who breed pugs by the hundred,—shall I, for
