rests. So it happened that in their most favovired haunts comparatively few 

 dragon-flies were seen. Occasionally a single Mschna or Somatoclilora would 

 appear in the open, flying abovit in a rapid, nervous fashion, and more rarely it 

 would be joined by another of its kind ; but after the usual aerial sculfie, both 

 would vanish over the tree tops, leaving the spot deserted for another long 

 interval. In any case, we were rather too late to find jEschna carulea at its best, 

 and of the few examples seen we secured two or three females. With Soma- 

 tochlora arctica we were even more unfortunate, only one or two being observed. 

 A single teneral ^ was found, evidently at the place of its emergence, but my 

 efforts to find the exuviae were of no avail. I marked the spot, however, and 

 later Dr. Calvert was successful in finding the cast-off skin which he very 

 generously gave to me. ^. juncea was the most numerous of the larger rpecies. 

 The only other species seen or taken were Cordulegaster annulatus, Lihellnla 

 quadrimaculata, PyrrJiosoma nijmphula and Enallagma cyathigenim. 



In Grlen Lochay it was interesting to find ^. ccerulea in the glade where I 

 first took it in 1895. Only one ? , however, was secured on the present visit. 

 It was resting on a well-known large boulder which has often before yielded 

 me specimens. Here ^E. juncea was present in some numbers, with one or 

 two C annulatus. 



Dr. Walker in his valuable Monograph alluded to above, refers to the 

 dimorphism existing in tlie females of ^Eschna juncea, which may be either blue 

 or yellow. In the former (homo^ochromatic) the coloiu* differs little from that 

 of the (J , except in the paler shade of blue. In the hetero-chromatic type all 

 the pale markings are green or yellow. He remarks that in a series of British 

 specimens which I sent to him, the postero-dorsal spot varies from blue to 

 greenish yellow, and the lateral spots from pea-green to pale yellowish green. 

 The hetero-chromatic type was well represented in a long series which I took 

 in Carnarvonshire in 1908. It is noteworthy that the nine females taken last 

 July in Eannoch and Glen Lochay are one and all of the blue type. — Kenneth

The name of Mr. H. Eowland-Brown, who has long been recognised as one 

 of our foremost collectors and students of Palffiarctic Butterflies, is a guarantee 

 for the value of the letterpress of this large and handsome volume. Though 

 avowedly of a slight and elementary character, it is written throughout with 

 all the author's well-known lucidity and charm of style, and forms a very 

 pleasant and reliable introduction to the study of the Lepidoptera. The general 

 arrangement of the first part of the book includes the subjects of classifica- 

 tion, nomenclature, distribution, migration, mimicry, protective resemblance, 

 collecting and preserving — all briefly but clearly treated ; while in the second
