No. XXX.— VITALITY OF A BUTTERFLY. 



While watching a cluster of about thirty Papilio pMloxenus which were 

 feeding on the flowers of a creeper, I noticed one of these butterflies had 

 a large heavy pin driven through the thorax. It must at some time have 

 been caught and pinned down, afterwards escaping. It was in very good 

 condition and the pin did not seem to interfere in any way with its powers 

 either of feeding or of flight, for when I tried to capture it by taking hold 

 of the pin, it darted away and showed itself as strong on the wing as any 

 other of its kind.

No. XXXI.— THE BED BUG {CIMEXROTANDATUS) ON THE 

 COMMON YELLOW BAT {SCOTOPHILUS KUHLI.) 



Now that the responsibility of the Bed bug f or " Kala azar " has been 

 established, an observation I made in 1907 of the presence of the bug on 

 two specimen of the Common Yellow Bat Scotophilus kuhli gains in impor- 

 tance. The bats were taken singly from holes in two cocoanut palms in a 

 village near Tellicherry and were badly infested. Captain Patton, I. M. S., 

 who kindly identified the bugs as Ciinex rotandatus desired me to collect 

 more bats of the species, but pressure of work of a different kind has left 

 me little leisure to do it and I venture to publish this note in the hope that 

 it will induce others interested to look for the bats and the bug on it. 



I may mention what struck me as curious at the time that the bugs were 

 on the bats themselves, rather an unusual habit for the insect. Perhaps 

 the reason was that it was 7 a.m. when I caught them and the bugs 

 starving over night had started just then to feed. The cocoanut trees 

 were about 30 yards from human habitation. The holes on them could 

 not be examined.

No. XXXII.— FLIES ON SNOW. 



On the snow covered slope of a glacier in Kashmir at appoximately 

 16,000 I noticed that part of it, which I was ascending, was discoloured by 

 what seemed to be a coarse, blackish dust, the snow elsewhere being clean 

 and white. My eyes being fixed on this discoloured snow as I climbed, it 

 suddenly dawned on me that the particles of ' dust ' were in motion, 

 jumping; and constantly shifting position. At first the thought occurred 

 that I must be suff"ering from a severe ' go ' of vertigo or mountain sickness.
