sentative of some seven hundred, showing but trivial variation. — Mr. 

 B. Adkin, a bandless form of Anaitis plagiata, a Eupithecia pumilata 

 with only two transverse lines, with nice forms of Camptogramma 

 bilineata, and other species. — Mr. Kaye, a bred series of Dap/mis nerii 

 from Dalmatia. — Mr. Adkin, a series of Cymatophora duplaris from 

 Rannoch, and contributed notes on the two very distinct forms. Mr. 

 Adkin made some remarks upon insects attacked by verdigris, and a 

 discussion ensued, Messrs. Montgomery, Kaye, South, and others 

 taking part. — Mr. Turner, the butterfly-like moth Synemon parthen- 

 oides, the sexually very dimorphic Ueteronympha merope, and other 

 insects from West Australia. — Mr. Rayward read notes on the curious 

 relations he had observed between ants (Formica flava) and the larva? 

 of Polyommatus icarus, and gave details of his experiments. 



April 25th. — Mr. R. Adkin, F.E.S., President, in the chair. — Mr. 

 Newman exhibited a branch of birch, upon the twigs of which were 

 about a thousand ova of Dimorpha versicolor, laid by females sleeved 

 around it. — Mr. Main, some small scorpions, the larva of a Mantis, 

 and an example of the large Acridium cegypticnm, all living, and sent 

 him from Hyeres by Dr. Chapman. — Mr. Sich, the ova of Lithocolletis 

 concomitella. a species closely allied to the more common L.pomifoliella. 

 — Hy. J. Turner, Hon. Rep. Sec. 



Lancashire and Cheshire Entomological Society. — This, the 

 concluding meeting of the session, was held at the Royal Institution, 

 Colquit Street, Liverpool, on April 15th, 1907. — Mr. W. Mansbridge, 

 F.E.S., Vice-President, in the chair. — Mr. Robert Newstead, F.L.S., 

 F.E.S., lecturer on economic entomology and parasitology at the Liver- 

 pool University, delivered a lecture upon the Tse-tse flies (Stomoxys) 

 and the Glossinas, the latter being the insects which produce sleeping 

 sickness. The lecturer described the life-history and development of 

 these most interesting flies, giving particulars of their habits and dis- 

 tribution, as well as the structural characters available for classifica- 

 tion. The life-history of Stomoxys remained unknown until worked 

 out by the lecturer, partly upon captive specimens, verified by his dis- 

 covery at Rossett, last year, of the fly in every stage. The flies were 

 found laying their eggs upon heating grass mowings, and feeding upon 

 the warm decomposing grass were embryos in all stages of develop- 

 ment. The mouth parts, which form the biting organ, were very fully 

 described by Mr. Newstead, and illustrated by blackboard drawings 

 and microscopic preparations of these — in many respects — remarkable 

 flies. Specimens of eight out of nine known species of the Glossinae 

 were exhibited by the lecturer, together with preserved larvae and 

 pupae, which had not previously been seen in public, the whole 

 showing in a remarkable way Mr. Newstead's great powers of observa- 

 tion and patience in working out the minute details of these previously 

 little known life-histories. — Mr. Joseph Collins, of Oxford, sent for 

 exhibition a box of Coleoptera and Diptera taken from moles' nests in 

 the vicinity of Oxford, and contributed notes. Working on lines sug- 

 gested by the researches of Dr. Joy, of Reading, Mr. Collins found 

 the following species, all of which were shown, viz., Quedius vexans, 

 common ; Q. longicornis, a short series, much rarer than vexans ; 

 Aleochara spadicea, fairly common ; A, succicola, Heterothops nigra,
