Callophrys ruhi, which for the most part resembled C. rubi, 

 but the knobs of the antennae had the red underside as in 

 C. avis, and the androconial brand was rather of the C. avis 

 form than that of C. ruhi, but intermediate. The white eye 

 borders were a little less brilliant than in C. rubi, and the 

 white line on the underside, though distinctly that of C. rubi, 

 was slightly nearer the base than usual in that species. The 

 specimen was taken where the species flew together at Amelie- 

 les-Bains, in April 1909. The specimen is now in the Museum 

 at S. Kensington. 



A NEW British Elater. — Mr. Donisthorpe exhibited two 

 specimens of an Elater, from Ireland, not in the British list. 

 One was taken by Mr. F. Bouskell and the other by himself 

 in Co. Kerry, in June 1902. They had been recorded as 

 Elater pomonae, Steph., but neither of the captors had ever 

 been satisfied that they were that species. Mr. Donisthorpe 

 suggested that they were either E. praeustus, F., or a new 

 species. In the general collection at the British Museum were 

 similar specimens mixed in the series of E. ])raeustus, the 

 latter either being a very variable species, or an undescribed 

 species was mixed with it in the National Collection. 



He also exhibited a specimen of E. pomonae for comparison ; 

 this particular specimen being of interest because it has a 

 fungus parasitic on it. 



Reappearance of Sunset Insects at Dawn. — Mr. Collin 

 said that he had observed that certain Diptera usually to be 

 seen about sunset were also on the wing about dawn, and 

 enquired whether the same fact had been observed in other 

 Orders. Dr. Chapman said that he was not aware that the 

 fact had been observed with regard to Lepidoptera, and 

 Mr. Green said that when he had been working light for 

 moths all night, he had never found the early evening moths 

 return in the morning; Mr. Buxton and Mr. Main, however, 

 both observed that Hyria auroraria flies both at dusk and 

 dawn. 



The " Death-watch " Beetles. — The President asked 

 whether any Fellow could state from his personal knowledge 

 that Anobium domesticum taps in the manner known as the 

 '■ death-watch." Xestobium tessellatum and Alropos divina-
