250 PROCEEDINGS OF THE 



elevation of about 2000 feet, what turned up but the Blennocam^pa 

 alchemillae, which I described before the Society last session, and 

 published in Part II. of the Proceedings. It was found among 

 AlcliemUla alp'ina. At the same place I found several interesting 

 Oxyura, which I have not yet succeeded in naming, and they are 

 probably undescribed. When the top was gained, I sat down to 

 enjoy the glorious view. I had not been seated five minutes, when 

 lo ! a Saw-fly landed on my trousers. He was instantly 

 pounced upon and safely bottled, when he soon paid the 

 debt of nature. An hour and a half was spent searching for 

 more, but not one was discovered. On coming home this speci- 

 men was found to be undescribed, although closely allied to 

 Nematus hyperhoreus, Thoms. I purpose calling it Clibr'icliellus. 

 During the search for this insect several interesting ichneumons 

 were found. Afterwards a descent was made to a loch in a corry at 

 the foot of the mountain, but nothing of importance was discovered 

 there. Botanically, Ben Clibrich is very poor; scarcely a plant of 

 any rarity was found, and even the common alpine saxifrages, 

 etc., were conspicuous by their absence, or very sparingly re- 

 presented. After the bootless journey to the loch, some time was 

 spent beating the birch and alder bushes along the banks of the 

 Clibrich burn (very much to the astonishment of some natives who 

 happened to be passing at the time), and here another new and 

 very distinct species of Nematus was found. This last discovery 

 is of some interest, as it is the second new species of the luteus 

 group that has been found in Scotland. In the *' Entomologists' 

 Monthly Magazine " for August, 1877, 1 have described it under the 

 name of N. antennatns. An attack was then made on the birches on 

 the banks of Loch Navar, but this turned out to be no easy matter, 

 for all the trees were infested with thousands of a Geometer larva. 

 It literally swarmed on them, especially on the old and scraggy 

 trees, so much so that after only two or three taps of the beating 

 stick I had hundreds not only in my umbrella, but all over my 

 clothes, and as when cast off they hang by a thread, the sub- 

 sequent process of clearing them, and making myself, to say 

 nothing of the umbrella, fit to enter a hotel, was a work of some 

 trouble. Many of the birches had been completely stripped of 

 their leaves by these wretches, and the whole plantation had quite 

 a withered and forlorn appearance. However, the wood yielded 

 some interesting ichneumons, as also Iloplocampa crataegi. Desist-
