species of Corydalis was described and figured by Prof. Wood-Mason

 Mr. Smith, of Tresco Road, Peckham, was elected a member. Mr. 

 Drury, F.R.H.S., presented to the Society's collections a large number 

 of the species of the smaller Lepidoptera. Mr. Ashdown exhibited 

 several specimens of the earwig, Forficula auriculuria, showing con- 

 siderable variation in the shape and size of the forceps. Mr. Burr 

 said that the example with unusally small forceps was a very rare 

 aberration. Mr. Harrison, photographs of Morpho epistrophis taken at 

 short intervals after emergence until the wings were fully expanded. 

 Mr. Edwards, a male and four forms of the female of the polymorphic 

 Papilio memnon, a very fine specimen of P. segonax, with the closely 

 allied species P. ulysses. Dr. Chapman, several species of Psychids 

 and their cases, Lycccna orion, Setina aarata, with strong black markings, 

 Gnophos variegata, Acidalia marginepunctaria , &c, taken the first week

 special reference to British species." In a chatty manner he discussed 

 the bibliography of the group, and remarked on the present backward 

 state of our knowledge of it. He referred to the present workers and 

 the work they were doing. The various sections and genera in the 

 group were distinguished at some length and where possible examples 

 were given from the English fauna. After giving many interesting 

 personal observations made in various parts of Europe, he pointed out 

 particularly the directions in which members could aid in the fuller 

 investigation of this neglected order.
