compartment, and with practice I could always distinguish hese from those 

 which contained the makers. Examined under the microscope, the partitions 

 are seen to be composed of very much contorted cells, but which have never- 

 theless, some resemblance to the regular woody structure. 



As a general rule the inquilines leave the galls some time after the gall- 

 makers ; at least this is always the case with those found in the vernal galls. —

Occurrence of Had ena assimilis in Inverness-shire. — On the first of 

 July last I took in the same locality where I have previously obtained this 

 species, a very rich dark coloured specimen, on the sixth a second, and on the 

 eleventh a third; the two latter were worn, and all are males. Scotch 

 entomologists should try to breed this fine species, and thereby settle the question 

 as to whether it is merely a variety of Cry modes exulis or not. I have taken 

 during the past few seasons 10 specimens, and had a good view of another, which 

 escaped. I have also seen 4 specimens taken in the same locality by a friend, all 

 of which are exactly alike, except the one taken on the 1st ult., which is much 

 darker than the rest, but scarcely to be called a variety on that account. C. exulis 

 is said to vary so much that it is difficult to obtain two specimens exactly alike. 

 It is recorded that it passes the winter in the larva state, making long galleries in 

 the moss, and is easily traced. Mr. Greening of Warrington and 1 have turned 

 up quantities of moss in Inverness -shire without finding any trace of larvae. It 

 has also been stated that the imago of exulis may be found in the evening on 

 grassy slopes creeping up the stems of grass, and in pairs hanging to the long 

 grass. Our assimilis is not to be found so. Exulis is said to fly in the day 

 time, and may be found hovering about flowers in the sunshine: it is not so with 

 assimilis. Only two of the above named specimens are females. — Nicholas 

 Cooke, Gorsey Hey, Mount Pleasant Road, Liscard, nr. Birkenhead. 23d

Ocourrence of Hadena assimilis in Perthshire.— Mr. W. Herd showed 

 me, on the top of Ben-y-Gloe, a living specimen of this rare moth which he had 

 taken the previous evening in Glen Tilt. — F. Buchanan White. 



Pachnobia alpina in Braemar.— When tearing up moss on a hill side in 

 Braerrar last July I found a chrysalis, which on the morning of my departure 

 disclosed a specimen of Pachnobia alpina. This may prove a useful hint to 

 those who have an opportunity of searching for this species. — J. S. Allin, 20 

 Beaumont Square, London. 



Trichiura cratsegi.— When at Braemar in July last year, my neighbour Mr. 

 Garrow found some larvae feeding on heather on one of the hills, and gave them 

 to me. They did not answer exactly to the book descriptions of any larva that 

 I could find, and I had some hopes of finding that I had got something new, 

 which, however, did not prove to be the case. They were full fed in the first 

 week of August, but did not emerge until the beginning of July of this year, and 

 then, they proved to be a peculiarly coloured variety of B. crataigi- very 

 dark ashy-gray or slate coloured, both body and wings, and without any trace 

 of brown. There were four males and one female. All the accounts I can 

 find of this moth concur in saying that the larva is found in May or June, and 

 the moth in September. Have any of your readers experience of its passing the 

 winter in the chrysalis state?— W. Tait, Broomend, Inverurie.
