of butterfly would adopt different resting positions in two 

 parts of its geograpliical range- — attitude depending on the 

 nervous system and being a far more deep-seated character 

 than colour or pattern. Mr. Lamborn had fortunately paid 

 especial attention to the point, and his observations, quoted 

 below, proved that Rutherford's statement was an entire 

 delusion. 



" I must have now seen hundreds of daedalus, for it is the 

 most abundant of all butterflies here, and, in my experience, 

 which Mr. Farquharson can confirm, it never rests on the 

 ground with the wings over its back ; though the few specimens 

 I have seen at night under leaves, in the attitude of sleep, of 

 course have the wings approximated. In the resting position, 

 with expanded wings, the body is inclined at a low angle to 

 the ground. It is rare to see this butterfly settle at all on 

 a green leaf : it prefers the ground, or a dead leaf on the 

 ground." 



It was satisfactory that the resting position of daedalus in 

 the intervals between its flights, as well as during complete 

 repose, had been now settled once for all. The colouring of 

 the under surface — apparently procryptic — was probably of 

 some value during that part of the period of complete rest 

 which fell within the hours of daylight. 



W. A. Lamborn's observations on the habits op the 

 WASP, Belenogaster junceus, F., and the attacks op 

 Tachinid plies upon it. — Prof. Poulton read the following 

 note received recently from Mr. W. A. Lamborn, recording 

 observations made at Moor Plantation, near Ibadan, Southern 

 Nigeria. 



" No. 426. 28th March, 1914. A nest of Belenogaster junceus, 

 F., was constructed under the verandah of my laboratory 

 during October, and in November four or five of the wasps 

 might be seen clinging to the under side, feeding and guarding 

 the larvae. A Tachinid was noticed one morning poised on 

 the wing, first on one side of the nest and then on the other, 

 and making every now and again a feint towards the nest, 

 sometimes actually coming into momentary contact with it. 



" Seeing that the wasps are well armed with a powerful 

 sting, as I know to my cost, and, moreover, that they have
