 Lepidoptera ; by Mr. Douglas. 



John Lubbock, Esq., of High Elms, near Farnborough, and the Rev. Hamlet 

 Clark, of Northampton, were elected members of, and John Walker, Esq., of Chester- 

 field, was elected a subscriber to the Society. 



The President announced that the prize offered for the best monograph of a genus 

 of Tortrices, had been awarded and sent to Mr. Logan for a monograph of the genus 

 Penthina. 



The President also announced that the Council had appointed Mr. E. W. Janson, 

 Curator to the Society. 



Mr. S. Stevens exhibited living specimens of Gracilia minuta, with the willow 

 basket-lid in which they had bred ; also Sericoris littorana reared from thrift (Statice 

 armeria) growing below Gravesend, and Elachista rufocinerea and E. cerusella taken 

 in copuld. He also exhibited a Psecadia funerella, taken early in June, near Kirkby 

 Stephen, Westmoreland, by Mr. HewitsoD. 



Mr. Bond exhibited several Psecadia funerella from Whittlesea Mere ; also Chilo 

 mucronellus, Nascia cilialis, Eupithecia sparsata, and Zeuzera arundinis, from the 

 same locality. 



Mr. J. F. Stephens exhibited pupa-cases of Zeuzera arundinis protruding from 

 reeds in which the larvae had fed ; and Mr. Bond stated that the pupae, although pos- 

 sessing but small spines, moved up and down the inside of the reeds with as much ra- 

 pidity as the larvae. Mr. Westwood said that he had seen cases of a Dipterous 

 insect, probably a Cecidomyia, sticking out of reeds just in the same manner as these 

 Zeuzerae : they would probably prove to be those of a new species, as this economy was 

 quite new in the history of the genus. 



Mr. F. Smith said that having in former years found Baris laticollis at the roots of 

 Sisymbrium officinale, he searched for it again this season ; but fouud, instead of those 

 insects, some larvae which he supposed to be those of Leiosoma punctata. He also 

 stated that he had observed attached to the posterior segments of the abdomen of a 

 common Hydrobius a receptacle containing eggs, one of which he had examined mi- 

 croscopically, and found in it a living larva. 



Mr. White read part of a biographical notice of Dr. Leach ; and also a letter from 

 Mrs. Hamilton, in which the capture of a Curculio, probably Acanthothorax longicor- 

 nis, in India, was recorded. 



Mr. Westwood exhibited drawings of the larva and pupa-case of Psyche nigricans,
