The new mites, parasitic on rats, which are described in thi^ 

 paper, are : Laelaps nuttalli, from Colombo, on Mus rattus and 

 M. norvegicus ; from Calcutta, on Nesokia {Gunomys) hengalensis and 

 M. rattus ; from Freetown, Sierra Leone, on M. rattus ; from Dutch 

 Guiana, on M. norvegicus. Microthromhidium gliricolens, from 

 Calcutta, found in the inner part of the ear of M. rattus. Schongastia 

 indica, from Calcutta, on Nesokia hengalensis. Schongastiella 

 hengalensis, gen. et sp. n., from Calcutta, in the inner part of the ear 

 of M. rattus. Central Formosa is given as an additional locality for

King (H. H.). Preliminary Notes on the Life-History of Argas brumpfi, 

 Neumann. — Bull. Entom. Research, London, vi, no. 2, September 

 1915, pp. 191-193. 



Argas brumpti has been collected in Somaliland, British East Africa, 

 and the Anglo-Egyptian Sudan. In the last-named province, specimens 

 were taken atGebelein in 1909 and again in August 1913 from crevices 

 between rocks and in caves, -where the ticks live among soil and 

 rotting leaves and twigs. No difficulty was experienced in inducing 

 them to feed on man or a rabbit, even when exposed to strong light. 

 An adult female was given human blood on 21st August, but afterwards 

 was fed on rabbits. Eggs were obtained in March and April 1914, but 

 efforts to rear the resulting larvae failed. A further supply of eggs 

 w^as obtained in October 1914, from nymphs collected at the same time 

 which had reached the adult stage. Pairing apparently takes place 

 at night. The ticks were confined in glass-bottomed pill-boxes con- 

 taining a little dry sand, in which the eggs were deposited. If 

 undisturbed, the female continued to brood the eggs until hatched. 

 In one case the incubation period was 26 days. The larvae do not feed 

 readily until about 10 days old. Those under observation attached 

 themselves promptly to a nestling sparrow and pigeons, but after 

 becoming partially gorged on these hosts they died, without dropping 

 off. Efforts to feed the larvae on adult sparrows, wild doves and bats 

 were not successful. Guineafowls proved suitable hosts, the larvae 

 becoming attached round the ear and on the upper part of the neck. 

 Nineteen larvae attached themselves on 13th December 1914 and 30 

 more two days later ; 26 were recovered between 21st December and 

 1st January. These larvae were fed on rabbits and at the time of 

 writing had moulted 4 times. Further details of the life-history are 

 leino[ secured.
