" British NoctufBand their Varieties," vol. iv., p. 122, reads as 

 follows : — *' My own captured (jilvago and ocellaris lead me to 

 believe in the identity of these species, as I have one (jilvago 

 with the tips of the forewings acutely pointed, as in ocellaris. 

 All my specimens, both of gilvaxjo and ocellaris, have been 

 taken in the noted poplar avenue of Hamburg, where gilcago 

 is the rarer and ocellaris the commoner species. The freshly 

 emerged specimens were taken on the trunks of poplars during 

 the afternoon." Mr. Tutt said that, in his opinion, the species 

 were abundantly distinct, but that ocellaris was yet so rare as a 

 British insect that one wanted to see more specimens, and to 

 know the life-history of the insect before one could object to 

 Fuchs' conclusion. He also exhibited four specimens of 

 Argyresthia atmoricUa taken by Mr. Atmore last June at Lynn, 

 Norfolk. He also exhibited a pupa-case of Thj/mdicus lineola 

 from the Essex salt marshes. He drew attention to the 

 structural characters exhibited by it, and pointed out that it 

 differed markedly from the pupa of Pamphila comma exhibited 

 at the last meeting. These structural differences led him 

 to suggest that the separation of the old genus Hesperia (as 

 still maintained by some Biitish lepidopterists) into Pamphila 

 and Thymelicus should be insisted upon. Mr. Tutt also 

 exhibited a long series of a Melampias which he had captured 

 at Le Lautaret in the Dauphine Alps, at an elevation of 

 7,000 — 8,000 feet. He observed that the specimens exhibited 

 were peculiar in some very important particulars. The males 

 varied somewhat in size and in the shape of the wings, and 

 the females showed a marked sexual dimorphism. Typically, 

 M. melampiis was looked upon as a somewhat round-winged 

 species, with black dots in the fulvous band and spots of the 

 fore and hindwings, the females very closely resembling the 

 males, but having somewhat paler fulvous (almost orange) 

 markings and spots beneath. M. pharte, on the other hand, 

 was considered to be a longer-winged insect, without black 

 dots in the fulvous bands and spots on the foi'e and hind- 

 wings respectively, whilst the female is characterised by its 

 pale orange (instead of fulvous) bands and spots, both on the 

 upper and undersides, thus making a marked sexual dimor- 

 phism. Further, M. melampiis was generally ccnsilered to
