[March, 



called augustana 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 bow stand as in 

 Dr. Staudinger's Catalogue. 



" No. 1037. Cruciana, Linn. Exccecana, H. S. Viminana, 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. augustana. — Thomas de Grey, Merton Hall, Thetford, 3rd

Another Xylina Zinchenii. — 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 bom with X. Zinckenii. 



It appears that my friend was out pupsD 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 his 

 " diggings." However, he fortunately found a pin between the walls of his waist- 

 coat, and a cylinder hat, in which the illustrious stranger was duly installed. Until 

 kindly taken out for me, it had ever since remained in his duplicate box. — Edwaed

Yama-mai culture. — I have received the following notes on Yami-mai culture : — 



"I had 22 eggs, and 15 larvae 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 Ist 

 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 eame 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
