species also described in the current PIM.M. ; and {g) Orepi- 
(lodera hnp)ressa, Fab., a littoral species recently introduced 
to the British list by Dr. Sharp from Hayling Island. 
It has now been found in an exactly similar locality at 
Poole Harbour by Colonel Yerbury. 
Asilid and Prey. —Mi-. G. T. Bethune Baker showed an 
Asilid which be had taken at IMacugnaga in August with a 
dead $ NomkuJes semiargus in its mouth. The Asilid held 
the Lycaenid until it was boxed. At the same time'another 
Asilid was observed with a beetle, which on being captured 
was relinquished and lost in the grass. 
Profe.ssor E. B. Poulton, F.R.S., said that undoubtedly 
the Asilids inject a poison into their prey through the 
proboscis which kills them immediately. 
Ant Host and Guest. —Mr. H. St. J. Donisthorpe showed 
a specimen of Claviger longicornis, Miill., with its 
host Lasius timh'aUis, Nyl., taken by Father Schmitz in 
Germany. He said this species should occur in Britain 
with the same ant, and that Father Schmitz had told him 
that April was the best month in which to look for it in 
the nests of umhrahis under deeply embedded, heavy stones. 
Teratological specimens. —Dr. T. A. Chapman exhibited an 
example of Pterostoma palpma, one of a number of similar 
specimens bred by Mr. L. W. Newman fi-om one brood of 
larvae, and which may be called as a varietal (or aberrational 1) 
name, var. hrevipennis. It is characterised by the extreme 
shortness and (comparatively) great breadth of the wings, a 
forewing measures 15 mm. long and 12 mm. from apex to 
tornus; a normal specimen taken at i-andom has these measure¬ 
ments, 24 mm. long 10 mm. wide. Dr. Chapman expressed 
regret that such specimens, involving structural variation, are 
despised in favour of mere colour fluctuations. In the pi-esent * 
instance there is a remarkable congenital variation tending to 
the formation of a race, by way of discontinuity. For com¬ 
parison a specimen of Libythea celtis with a shortened wing was 
shown. It is impossible in the specimens without the histories 
to say that they were not of identical origin, yet the one is 
congenital (or even racial), the other the result of a displaced 
antenna in the pupa.
