called augiistana in this country is the exccecana of Herrich Schaffer, and probably 
the cruciana of Linnaeus." The discovery of the true H. augustana in this country 
therefore adds another species to our lists, where the two should how stand as in 
Dr. Staudinger's Catalogue. 
" No. 1037. Cruciana, Linn. Exccecana, H. S. Yiminana, Gu. 
No. 1038. Augustana, H. S. 205. H. S. 262." 
In the hope of re-visiting the spot where I took my specimen and finding more, 
I have, up to the present, omitted to mention the circumstance, but was reminded 
of it by receiving a copy of Dr. Herrich Schafier's work this morning from Mr. Van 
Voorst, which enabled me to compare the specimen with his figure 262, pi. 51. 
I took the insect at High Force, near Middleton Teesdale, in the county of 
Durham, in August, 1866. It seems very distinct from the species which has been 
hitherto accepted as H. augiistana. — Thomas de Grey, Merton Hall, Thetford, Srd

Another Xylina Zinckenii. — The following must be amongst the earliest captures 
of this rarity. A brother collector, a neighbour, lately brought me, as a present, 
what he and his friends at the time (October, 1865) considered a strange example 
of Acronycta psi. At this date it may be borne in mind that Dr. Knaggs had not 
identified anything British born with X. Zinckenii. 
It appears that my friend was out pupas digging in the northern environs of 
London, when, rising from the root of a poplar, he was surprised to observe this 
fine example of what stiuck him as one of a second brood of A. psi at rest upon 
the bark. He had neither pill nor collecting box— merely a small cradle for bis 
" diggings." However, he fortunately found a pin between the walls of his waist- 
coat, and a cylinder hat, in which the illustrioiis stranger was duly installed. Until 
kindly taken out for me, it had ever since remained in his duplicate box. — Edwaed

Tama-mai culture. — I have received the following notes on Tami-mai culture : — 
"I had 22 eggs, and 15 larvge hatched out from May 16th to June 2nd. 
I fed them on the common oak, in a wooden box 18 x 14 x 8 inches, the front 
was wire-cloth, and the branches were inserted through holes in the bottom 
of the box into a basin of water. Fresh food was supplied at first every 1st 
or 2nd day, but afterwards every 3rd or 4th day. There was no thermometer in 
the room, nor fire, nor artificial heat ; a quantity of cotton and woollen cloths and 
yarns were kept in the same room. It has been a very warm season, and the 
temperature would range high ; the attic in which they were kept faced south, and 
measured 21 x 18 x 8 ft., the windows were open by day, the door generally open, 
there was but little draught, and the room was not exposed to the sun's rays. 
I have four cocoons, spun July 16th, 17th, and 20th. The worms seemed healthy 
when hatched ; two died before moulting ; the rest all attained a good age. The 
disease shewed itself by changing the worm to a greenish-white, and the dark 
spots shewed themselves and spread up the worm till they became soft and black 
all over. I have no proof that the disease was infectious ; I tried every means to
