Lyccena found at Djebel Zebayir was not rare here, but very active 

 and hard to catch, as was also a little Pyrgus very like ours ; besides 

 these I saw Pyravieis cardui, but did not take it. I was told that 

 great numbers of moths come over in certain winds, large ones among 

 them, but the biggest which I saw was Deiopeia pulchella ; an Agdistis, 

 mvich smaller than ours, was not rare among the Armeria. Most of 

 the time I was there it w^as blowing very fresh from the southward, 

 which made flying insects very hard to catch. I pinned up a nice 

 little lot of Hymenoptera, and secured some fine scorpions and a 

 Galeodes, a most formidable looking and very venomous spider-like 

 beast, nearly two inches long. Land shells were rare, I could only 

 find two species, and those only as dead specimens, but I collected a 

 nice little set of marine shells from the rocks on the north side of the 

 island. Altogether I do not consider that I did so very badly 

 at Perim. 



9.30 a.m., April 5th. Arrived at Aden half-an-hour ago ; we coal 

 and leave for Colombo (Ceylon) on the evening of the 7th. Iso doubt 

 I shall be able to get a run on shore here (indeed, the Captain is 

 desirous that I should take every opportunity of landing, which you 

 may be sure I am by no means loth to do) ; but it looks a very barren 

 and uninviting place, nothing but black, rugged volcanic rocks, attaining 

 a height of 1700—1800 feet, and with only the very faintest tinge of 

 green here and there, still, I have no doubt that there are things to 

 be got for the working— at any rate, I must have a try before we 

 leave. The heat is very trying (85° in the shade as I write), but so 

 far I have had very good health ever since leaving England.

THE LIFE-HISTORY OF THE NEW TINAOMA {T. BETULM) OP 



THE BIRCH. 



BY JOHN H. WOOD, M.B. 



1 had been in the habit, when searching the birch bushes — that 

 richest of plants for micro larvae — of occasionally finding a leaf from 

 which a small oval piece had been cut out close to the mid-rib, but, 

 thinking it was probably Tinagma resplendellum, making trial of a new 

 food, I took no particular notice, until one day happening to look a 

 little more critically, I was surprised to find that the larva, whatever 

 it might be, had at first lived in the twig, and had only entered the 

 leaf, which it did by passing up the stalk, in order to cut out its case ;
