required. On the summit of Snaefell, 2,000 feet high, I found Cidaria 

 populata and Clianeas graiiiinis. In collecting larvae I did not work 

 much, but brought home a good number oi DianthcBCUE in Silene juaritima, 

 which had been gathered for me previous to my arrival. During a visit 

 to the lovely Glen Helen, I noticed larvce oi Abraxas idmata suspended 

 from an elm tree overhanging a waterfall, and, pulling the boughs towards 

 me with some difficulty, I picked off about two score. In my garden, 

 on sallow, I discovered about twenty full-grown larvse of Sphinx populi 

 and Arctia fuliginosa feeding on ragwort. Agrotis ripcc occurred on 

 Chenopodium on the sandy shore, where I dug up about one dozen, 

 but found them much less common than on the opposite coast in 

 Cumberland last year. 



In conclusion, it may perhaps be interesting to botanists to hear that 

 Brassica moneiisis was growing plentifully on the ground above the 

 harbour ferry at Ramsey. — J. Jager, 180, Kensington Park Road,

Zeuzera pyrina (^sculi) in 1890. — I am glad to be able to re- 

 port another successful season with this species. I have again found 

 the moth abundant in the locality mentioned in the Entomologist of 

 September last (vol. xxii., p. 234), and also in Highbury Fields, a park 

 under the control of the County Council. The most remarkable take, 

 however, was from a solitary ash tree in a front garden opposite my 

 own door. This tree with a diameter of only a triQe over three inches, 

 at a height of four feet from the ground, yielded no fewer than twenty- 

 seven specimens. From June 24th, when I found the first moth, till 

 July 26th, I visited all three localities once, and sometimes twice each 

 day, and was thus enabled to be sure that my captures were made 

 within a short time after emergence. In the old locality sixty-eight 

 specimens were found, in Highbury Fields twenty- five, and on the 

 solitary ash tree twenty-seven. In addition to these, a female was 

 observed on the trunk of an oak at Highgate, when sugaring there 

 on July loth, and another was bred on July 15th from a pupa found in 

 my lilac. Warm morning sun seemed necessary to bring out the 

 imagoes. When the mornings were wet and the temperature low, none 

 emerged. When the early morning was bright and warm, followed by 

 rain before mid-day, some emerged, but were all more or less crippled. 

 The proportion between the sexes was curiously different in the three 

 localities. In the two new localities where I believe I captured every 

 specimen that emerged, the results were : in Highbury Fields, four 

 males to twenty-one females, from the solitary ash tree, twelve males 

 to fifteen females ; whilst in the old locality where, however, the 

 height of the trees made it impossible to be sure that every specimen 

 came under observation, twelve males and fifty-six females were 

 obtained. In the old locality the ash was again almost the exclusive 

 home of the insect, one specimen, however, emerged from a privet 

 bush, and there was evidence that the hawthorns were infected. In 

 Highbury Fields, the trees attacked were, without exception, young 

 elms of a diameter of from an inch and a half to three inches ; the 

 young planes which alternated with these were entirely unaffected. 

 The damage to the trees was very considerable ; in the case of the 

 large trees whole branches were killed, whilst the stems of the young 

 trees were so weakened as to snap across in a high wind, and the
