insect the type of a new genus Druryza, as in many 

 ways it differed from the typical Papilio or swallow- 

 tail butterfly. Both by the nervures, by the habit, and 

 much greater breadth of wing, of any species excepting 

 the Ornithoptera, it seemed to merit generic distinction, 

 since fine specimens measure seven inches across the wings. 

 There are many points of resemblance, however, between 

 this fine insect and the smaller P. Ridleyanus, also from 

 Tropical Africa. Both seem to resemble certain Acrace in 

 form, a group almost peculiar to Africa. Mr. H. D. Wheeler 

 recently sent to his father, Mr. R. Wheeler, of Manchester, 

 six specimens captured by himself in the neighbourhood of 

 the Ogowe River, about 300 miles from the sea. Of these 

 six specimens, five were in very good condition, and one of 

 these I have the pleasure to exhibit this evening." 



Mr. P. Cameron, F.E.S., communicated Part IV. of his 

 Hyvienoptera Orientalis. The PRESIDENT of the Section 

 gave an address on the hive bee ; which was illustrated by 

 diagrams and by a number of anatomical preparations 

 shown under the microscope by Mr. Boyd.
