(exit: ) 
apparently a new species, which resembled a species of 
Amphisternus of the family Hndomychide. 
Lrvinc Luminous Cotroptera.—Dr. G. B. Lonestarr 
exhibited living specimens of the luminous Elaterid Pyro- 
phorus noctilucus, L., brought from Trinidad by Dr. F. L. 
J. M. de Verteuil, R.N. Dr. Longstaff had observed that 
when chloroformed the green lights became very brilliant, 
but were soon eclipsed. As the lights faded in a normal way 
they appeared to pulsate. 
Rare AND New British Cotzoprera.—Mr. H. Sr. J, 
DonisTHoRPE exhibited on behalf of Prof. T. Hupson Brarr 
and himself specimens of Quedius riparius, Kell., and 
Trypodendron quercus, Kich., taken by them at Porlock, 
Somersetshire, on April 16th and 17th. The former insect 
was found somewhat sparingly in flood-refuse caught by 
fallen logs lying in one of the mountain torrents which came 
down from Exmoor; it was to be found only in flood-refuse 
actually over the surface of the water—apparently when the 
flood-refuse is deposited on the banks the insect very quickly 
leaves it. There are only records of the capture of this 
insect—by Mr. Kidson Taylor, in Derbyshire, one specimen 
—aud by Mr. Chitty in flood-rubbish on the river Beauly, 
Inverness-shire, since Mr. Blatch discovered it at Porlock in 
1896. With these the exhibitor showed specimens of Quedius 
kraatzii, new to Britain, taken by him at Chiddingfold in 
1898, but not exhibited before, to compare with Q. ripartus, 
both species having the same habits. It was stated that 
unlike the latter, kraatz/i had never been taken elsewhere in 
Britain, though he had found it on various occasions since in 
the old locality. The 7'rypodendron was found in the bark 
and in the solid wood of a small oak bough; there are few 
records of its capture outside the Sherwood Forest district. 
Also Hydrovatus clypealis, Shp., taken by them on April 14th 
at Worle near Weston-super-Mare. This very local little 
water-beetle is only recorded from Portsmouth by Canon 
Fowler, but has since been taken at Sandown, I.of Wight, by 
Prof. Beare, and in the New Forest by Dr. Sharp. 
Dirreron associateD with ANnTSs.—Mr. DonistHoRPE also 
showed the larva and pupa of a Dipteron of the genus
