together, forming a kind of chamber above the mud — a place where 

 the saltatory powers of Delphax would be of little avail for escape — 

 were great numbers of their sucked skins with gorged individuals of 

 those species ; the Alysiid, however, was more probably in search of 

 a dipterous victim, for no males were apparent. The mortality must 

 be very great and the oviposition of the survivors prolific, for in 

 September perfect Delphax, though not rare, are only in their tens 

 where now the larvae are in their thousands. I fancy other Cocci- 

 nellaB must attack them too, for both Micrasjns 16-imnctata and 

 C. ll-punctata were common, though I saw with careful searching 

 but a single specimen of an Aphid, which was a winged Hyalopterus 

 arundinis, Fab.— Claude Morley. 



On the Habits of Parydropteea discomyzina, Collin (MS.) In 

 the middle of September, 1910, two specimens of this new dipteron 

 occurred to me in a salt-marsh at Southwold ; this was just before 

 dusk. Accordingly at dusk I searched for the species at the same spot 

 on several subsequent occasions, but with no success till the 17th of 

 last July, when four examples were secured, with several the next 

 day. These were only aroused from the salt-marsh plants {Aster, 

 Sueda, Spergularia, Atriplex, &c.) by smoke ; then they would jump 

 from the mud level to about an inch up the pressed-back herbage, 

 and great care was necessary in bottling or a second leap was made — 

 usually downwards, though the insect invariably headed upward. 

 This frequently led to loss, as it was usually effected through some 

 aperture in the stalks and the fly lost to sight ; nor was it often 

 again aroused, even by smoke. Thus I lost nearly half those seen. 

 The appearance when alive is that of a shining and peculiarly convex 

 Salda, for the wings are pressed flat to its back and apically deflexed ; 

 and the saltatory powers are very similar in degree. This time it 

 occurred in the same salt-marsh as formerly, though some hundred 

 yards from the original spot, where a diligent search failed to reveal 

 it. In both situations it was found on ground just too wet to lie 

 upon (though I did !), and yet by no means covered with water ; so 

 salt was this that sand-hoppers and whelks kept Pari/drojHera 

 company. In all I secured some two dozen examples with three 

 hours' close work. — Claude Morley ; Monk's Soham House, Suffolk. 



The Adams Collection op Lepidopteea. — This exceedingly rich 

 and very extensive collection of Lepidoptera is now installed in the 

 Natural History Museum at South Kensington. It is contained in 

 sixty-eight cabinets and numerous store-boxes. The number of 

 specimens probably totals something like one hundred and fifty 

 thousand, among which are hundreds of types. 



The Suppert Collection op Butterflies. — The large collec- 

 tion of African butterflies, with its numerous types, formed by the 

 late Herr B. Suffert, of Berlin, has passed into the Joicey Collection. 

 Entomologists are invited to compare their specimens with the 

 types. — J. J. JoiCEY ; The Hill, Witley, Surrey.
