Laclmeids on the other, were very different, both as to their 
movements and their manner of resting, the moths flying by 
night, the butterflies by day; the moths resting with the 
upper-sides, the butterflies with the under-sides of the wings 
exposed. It would be very interesting to know whether in 
the cases exhibited the butterflies and moths both flew by 
day, and both rested in the same manner. This might not be 
difficult to ascertain from the collector who supplied the speci¬ 
mens, and would be of the greatest value. 
Beetle Parasite. — Mr. II. St. J. Donisthorpe exhibited 
examples of Methoca ichneumonides, parasitic on the larva of 
the Tiger Beetle, taken by him in the Isle of Wight. He 
said that it was apparently unknown in this country that 
Methoca ichneumonides is parasitic on this larva. Its life 
history has been worked out by Bonuman (Tijd. voor Entom., 
1909), and Adlery (Arkiv. for Zook, 1906). They record it 
pai’asitic on Cicindela campestris and C. sylvatica. He had 
taken it at Blackgaug Chine, where it would be parasitic on 
C, germanica. With these examples he also showed the 
hosts, C. caiupestris, C. sylvatica, C. germanica, and a Tiger 
Beetle larva. 
Mr. Donisthorpe also exhibited an example of Ptinella 
hritannica, Matt., found in a mole’s nest at Burwell Fen last 
month. This is only the third British specimen yet recorded, 
and apparently the fourth only in Europe, one having been 
reported from France. 
Papers. 
Mr. Norman H. Joa', M.E.C.S., read a paper “ On the 
behaviour of Coleoptera during Floods,” and exhibited living 
specimens to illustrate the remai'kable power of Dianous 
coerulescens in '• skimming ” on the surface of water. 
The following papers were also read :— 
“ A Revision of the genus Diplatys, Serv.,” by Malcolm 
Burr, D.Sc., F.L.S., F.Z.S., etc. 
“ On the Geometridae of the Ai’gentine Republic,” by Louis 
B. Prout.
