undoubtedly horeaUs. The discrepancy I speak of is this : — In the " Ecvue" it is 

 emphatically stated that " le secteur suhnodal n'est 2yos hifurqu6 sous le pterostigma, 

 ce que se voit, au contraire, chez toutes les autres especes europeennes (excepte 

 chez Virene) ; " and in the " Annual " the same character is mentioned ; yet Brauer, 

 in his most useful work, " Neuroptera Austriaca," p. 20, states that this sector 

 divides under the pterostigma, but that the upper bi-anch is much finer than in 

 other species ; and this exactly tallied with my own examples. Dr. Hagen informs 

 me that, in the specimen sent to him, the sector is furcate in the right fore-wing, 

 and simple in the left (which I had not noticed) ; and that previously to 1858 he 

 had seen no example in which the sector was furcate, but that he has since found 

 that it varies in this respect. Another character mentioned by Brauer is not stable, 

 viz., that between the upper branch of the sub-nodal sector, and the sector above it 

 {sector nodalis of Brauer), there are two rows of cells, whereas, in other species, 

 there is generally only one ; I find both states to exist in my three examples. 



Eespecting the distribution of horeaUs, it may be mentioned that the species 

 appears to be decidedly northern. Zetterstedt states that it is common in 

 Lapland, and occurs in Sweden. It has been found, but rarely, in Silesia and 

 Switzerland, and Dr. Hagen possesses it from Western Siberia and Kussian 

 America? (the example from the latter locality being ^. Sitchensis of Hagen, and, 

 as he informs me, probably identical with borealis.) Brauer includes it in the 

 Austrian Fauna. 



The other Dragon-flies that I found at Rannoch were few in number, the 

 season being too little advanced. Cordulia arctica occurred not uncommonly on 

 the spongy moors, but was difficult to follow without getting most unpleasantly 

 bogged (this species, as British, has only been hitherto found here, and at Killarney, 

 in Ireland) ; Cordulegaster annulatus was quite common in the same localities, and 

 more easy to capture ; Libellula quad/rimaculata was found in some numbers about 

 moor-ponds ; Agrion minium occurred in the same situations, and A. cyathigerum 

 was seen on the shores of the Loch. The beginning of June is undoubtedly too 

 early for a locality in which, at that time, the snow still lies thickly on the tops of 

 the hills. — R. McLachlan, 1, Park Road Terrace, Forest Hill, September 8th, 1865. 



Ilonanthia humuli, Fieber ; a mining Hemipteron. — Prof. August Menzel men- 

 tions in his " life of the late M. J. J. Bremi" (" Forscherleben eines Gehorloscn, 

 Zurich, 1857," p. 29) the latter's discovery, that the larva of Monantliia convergens, 

 Klug. (M. humuli, Fieber,) mines up to the time it casts its first skin, and that this 

 is the only instance where we notice this habit amongst the Hemiptera. 



Messrs. Douglas and Scott tell us, in their recent woi'k ("British Hem, 

 HeteroiJtera, p. 245), on the authority of Professor Burmcister, that the said insect 

 occurs on Myosotitf palustris, and I hope this note will induce some observers to 

 verify Bremi's observation, and to give us further particulars about this singular 

 fact. Perhaps it will also serve as a stepping-stone to the elucidation of the habits 

 of other species of the genus. — Albert Mullek, 2, Camden Villas, Penge, S.E.,

Curious habit of Notoxus monocerus. — I recently picked up a dead specimen of 

 one of the common Proscarabwi, which had been trodden upon in a dusty roadway 

 near this place, and was somewhat surprised to find upwards of half-a-dozen of
