Dr. Chapman exhibited and communicated the following note: — 



" 1. A male and female of Tnchvmma tibialis, Stephens = trtnleta, 

 Klug, which Mr. Morice tells me is the correct name of this, our 

 common hawthorn species. I also show two eggs laid beneath the 

 upper cuticle of hawthorn leaves. With a lens and a light behind 

 the leaves it should be possible even in the artificial light of our 

 meeting room, to see the brown-black eyespots of the developing 

 larva), and their weird to and fro movements at short intervals. 



"2. Specimens of Psila rosae, bred from parsnip. This is the 

 ' carrot-fly,' a well-known pest of carrots and to some degree of 

 parsnips. It was interesting to note that a bit of the inside of a 

 parsnip put on damp sand to rear the larva of the fly, developed 

 roots below and leaves above. The roots arise from brownish 

 callosities, whilst similar but greenish callosities have arisen where 

 leaves developed. 



"3. Specimens of the somewhat rare fly Penoinyia hijosrijania, (its 

 parasite and puparia), bred from Datura straiiwnium. Mr. Collin 

 gives me the name and says he has only two specimens, females, 

 that were bred from Atropa belladonna — named from being bred from 

 Hi/oscyannm — all belonging to the atro)>a branch of the Solanacea; 

 (night-shades) — If it attacked potatoes (belonging to the Solanacem 

 branch) it would necessarily be a much commoner insect than it 

 appears to be." 



Mr. R. A. R. Priske exhibited the shells of a number of species 

 of British Water Mollusca, including Linni(ea auncularia from 

 Uxbridge and L. staiinalis from Staines, both species particularly 

 well developed and not worn ; Vivipara contecta from Staines, 

 unusually large and perfect, and F. vivipara from Cheshunt ; 

 Anudonta cy;/nea from West Drayton and A. anatina from Staines ; 

 Vnio tioniduH and U. pictoniin from Shepperton ; a very variable 

 series of Siilucriiim corneioii from Uxbridge ; and N. riricola from 

 W. Drayton. 



Mr. S. R. Ashby exhibited several drawers of his finely mounted 

 British Coleoptera comprising the Ground beetles of the genera 

 Ilarpalus and Pterostichns, the Water beetles of the genera Ariabioi 

 and liliantus, the Lucaniila-, Scarahiridie, Buprestvloi, FAaterida., etc., 

 and the genera Otiorrln/nchnK, Polydrxmin and Phyllobins. 



Mr. H. Moore exhibited a number of cockroaches and earwigs 

 taken alive in a city warehouse, in merchandise from Japan, in 

 April, 1916; the nests of a Weaver-bird (Ploceidfc) from Simons 

 Bay, S. Africa ; and the eggs of the Tropic-bird, PJitrtlion
