abundant on the Guernsey coast; it is also very abundant in 
Sark and Herm. The imagos usually make their appearance 
towards the end of June; but on visiting Herm, on July 30th, 
I was surprised to find a great number of cocoons, from 
which the perfect insect had not yet emerged. ‘The moths 
kept coming out for a fortnight after this date. On August 
11th one emerged, still bearing the head of the larva: this is 
a very rare form of monstrosity (see Entom. v. 268). I think 
Z. Lonicerz is absent from Guernsey and Sark. 
[Great care is necessary in deciding between the two 
species here mentioned. I willingly admit that I am totally 
unable to differentiate them in print; moreover I have almost 
invariably found that the specimens so kindly sent me by 
correspondents in the north’ as one species, when submitted to 
the highest authority in the south are returned to me as the 
other. Can any reader of the ‘Entomologist’ give any 
information as to the pupation of Trifolii? Have Mr. Luff’s 
cocoons been submitted to a critical examination by Mr. 
Birchall, Mr. Doubleday, or Mr. Weir? I should feel really 
gratified, not only on my own account, but on that of those 
who so kindly favour me with their company on Friday 
evenings, if entomologists would send either specimens or 
information concerning the pupa or cocoon of Trifolii. It 
may seem a strange confession, but I am in a state of positive 
ignorance whether this species spins a shuttle-shaped cocoon 
on the culms of grasses, or an oval cocoon low down in the 
herbage, or absolutely enters the earth to undergo its trans- 
formation under ground. Im this case, as in that of the 
almost equally common insect, which I have described under 
the name of Davisellus, and which possessed at least three 
prior names on the Continent, I feel the humiliation of 
exhibiting such gross ignorance. It is no excuse that this 
ignorance is shared by my fellow-countrymen. In both cases 
it is totally inexcusable; and the plea that others are equally 
ignorant is, to say the least, puerile and unavailable.—

Sesia Ichneumoniformis.—I took one at rest, July 6th, at 
the top of the cliff, near Doyle’s Monument, Guernsey.

June.
