238 THE ENTOMOLOGIST. 



Stauropus fagi in Eastbourne on July 11th, I should like to say that 

 a large female specimen was taken near Godalming this year. The 

 date was, I think, June 18th. It was resting on a tree trunk, but was 

 not in a quite perfect condition. It laid several batches of eggs, 

 amounting to a total of about eighty. I do not know if this is the 

 full number, as she may have laid some before capture. The eggs 

 were fastened singly or in irregular batches to the inside of the glass 

 jar in which she was confined. They hatched at intervals on 

 June 2Hth probably corresponding to the intervals between the laying 

 of each batch of eggs. I do not know whether Staurojjus fagi is of 

 regular occurrence in the Godalming district, but I have not met with 

 it there myself before. It is by no means a common species, and it 

 would therefore seem desirable to publish the localities in which it is 

 found to occur in order that we may have a better idea of its distri- 

 bution than at present seems to be the case. — H. G. Q. Wales. 



Notes on Papilio demoleus. — This handsome butterfly is 

 common at Eawalpindi, Punjab. It is on the wing there from 

 April till December, and eggs and larvae are abundant throughout 

 this period. Eggs are easily obtained by taking up one's stand near 

 an orange or lime bush and carefully watching the female. She 

 flutters about the bush and settles for a moment here and there, 

 depositing a spherical, light yellow-coloured egg. The eggs hatch in 

 from two to five days. The young larva is dark brown, with irregular 

 white markings, and a number of short spines. The head and two 

 longer spines on the first segment are yellow. The young larva feeds 

 and rests openly on the upper side of a leaf, and closely resembles a 

 bird's excreta. The larva retains this colouring through two or three 

 changes of skin, till about twelve days' old, when it changes entirely. 

 Tlie body becomes smooth and apple green in colour, head and legs 

 brown. On the third body-segment there is a dark eye-like mark on 

 each side, these marks being connected by a brown and yellow trans- 

 verse band. On the fourth segment is another brown and yellow 

 transverse band. The underparts and two spines on the first and 

 two on the last body-segment are yellow. On the seventh, eighth, 

 and ninth body-segments are irregular brown markings edged with 

 white. The larva, when irritated, protrudes from a fold in the first 

 segment, just behind the head, a fleshy V-shaped organ similar to 

 that of Papilio machaon. This organ is orange-yellow in colour, 

 and has a wet, sticky appearance. After about fifteen days from 

 hatching the larva, which is then about one and a half inches 

 long, prepares to pupate. It attaches itself to a twig in an 

 upright position by a silken pad at the claspers and a silken 

 band round the body. A day or two later it turns to a pupa, 

 which is usually green but sometimes brown. The butterfly emerges 

 in about twenty-three days from the hatching of the larva. Larvffi 

 were abundant up to the beginning of December, but I found none 

 during the cold weather. I tried to keep several of the larva) found 

 in December, but only two survived the cold weather. They grew 

 very slowly, and when fully grown were only half the size of the 

 June larvse. One turned to a pupa on March 10th, 1916, and a small 

 deformed butterfly emerged on April 2nd, 1916. Young larvae,
