faces of very large rocks or stones, and mentions their extraordinary agility in 

 locomotion. I am not aware of a similar habitat as the Southern Europe species of 

 the genus having been recorded for maritima. — A. D. Imms, Linthurst, Oxford Koad,

A probable case of miff rat ion in Leucorrhinia duhia, J', d. L. — In the " Field " 

 for June 23rd last, "J. C." records an occurrence at Scarborough of considerable 

 scientific impoi-tance. He says that along the north and south foreshores and cliffs 

 the visitors were surprised by a large number of small dragon-flies (subsequently 

 identified as this species) which frequently attached themselves to people's dresses, 

 greatly to the alarm of many timid individuals. He further states that the general 

 impression is that the fliglit came over the sea, and that one or two keen observers 

 declare that they saw them approach the shore from that source. — Id. 



The habitat of Thaumatoneura inopinata, McLach. — In this Magazine for 

 June, 1897 (2nd series, vol. viii, pp. 130, 131), I described under the name of 

 Thaumatoneura inopinata, from a mutilated example, the locality for which was 

 unknown, a remarkable new genus and species of CalopterygiiKB obtained at a sale. 

 From collateral evidence I ventured to suggest that the insect perhaps came from 

 China or Japan. I have this moment received information from my excellent friend 

 and colleague Mons. Rene Martin (of Le Blanc) to the effect that he has seen a 

 perfect specimen in a collection from Chiriqui (Panama). My hazarded suggestion 

 has proved very wide of the mark, but I rejoice in the fact that the real locality is 

 known.— R. McLachlan, Lewisham, London : July IMh, 1900. 



Dragon-flies in the Island of Alderney : including Lestes barbara, F. — There 

 are only three species of dragon-flies that I can personally verify for certain as 

 occurring in Alderney, namely, Sympetrum flaveoluni, L., and Lestes barbara, F., 

 both of which may be found in considerale numbers round a pond on Longy Common, 

 and of which I have captured accordingly several specimens. The third species is 

 an jEschna {sp. ignot.), seemingly dark and dusky, but of which I have only noticed 

 two or three specimens, in each instance too far away to determine the kind, and in 

 one case flying high up and quickly across the field and out of sight. The one 

 locality in the Island for dragon-flies is the above-named pond. The $ of Sympetrum 

 Jlaveolum is to be found in comparison of the ? in the proportion of ten to one at 

 least. Away from the said pond I have literally only seen two other dragon-flies in 

 Alderney — one flying over one of the fields flanking the Longy Road not far from 

 the Strangers' Cemetery, and which may have been an ^sehna or else Sympetrum 

 Jlaveolum ; I was not near enough to pronounce with certainty. The other was 

 seen in 1897 flying down over one of the valleys near the old lime kilns, and appeared 

 to me then to be Libellula quadrimaculata, L. — F. A. Waleek, Belle Vue Hotel,

\^Leste.i barbara was for long in the British List on the authority of one example 

 said to have been taken in Ireland. Mr. Lucas, in his recent work, relegates the 

 species to the " Reputed British." But Mr. Lucas includes the insects of the Channel 

 Islands as " British," therefore L. barbara should no longer be only " reputed," 

 supposing Mr. Lucas' views to find common acceptance, which they do not. On this
