CURRENT STATUS

Argas vespertilionis 1 adult, N's 



& larvae 



Bat ( Scotophilus kuhli ) 



Guindy, Madras, India 



XII. 1912 



Rec'd. from Captain W. S. Patton 



[Nos. 2745 & 2746 used for raising 

 experiments.] 



Note: Capt. Patton writes, 

 19. III. 1914, the N's fed on him 

 26.x. 1913, took 20-48 minutes to 

 feed (shortest & longest time); 

 the larvae were taken off a bat, 

 12. XII. 1912 so that the N's 

 (1st stage) fasted until 26. X. 1913, 

 he finds they can fast nearly 1 year. 

 Without again feeding the 1st stage 

 N's moulted to 2nd stage N's on 

 9. XI. 1913 & these lived unfed for 

 4 months. They do not feed well on 

 pigeons, guinea pigs, etc. On 

 dissection they show Leishmann's 

 granules in the Malpighian tubes, 

 but the bat ( Scotophilus kuhli ) 

 has not been found to have 

 spirochaetosis; he is sceptical 

 regarding the granules. Letter 

 destroyed, G.H.F.M.
