and is usually rigidly excluded from all dairy factories and all good 

 cheese stores. 



Tyroglyphus farinee, Koch. Wheat Mite 



In 1893 at a meeting of the Entomological Society of London, 

 Mr R. W. Lloyd exhibited specimens of this "wheat mite" which 

 was found in wheat imported from New Zealand. The species was 

 probably introduced into New Zealand from Europe at an early date. 

 Mr W. W. Smith informed me some years ago that it was very 

 common in grain sheds at Ashburton, and it is probably widespread. 

 It is occasionally found on dry cheese, and is recorded as T. siro; 

 but it is considerably smaller than that species. 



Tyroglyphus longior, Gervais 

 Recorded from Wellington; probably widespread. 



Cytolichus nudus, Viz. Internal mite of Fowls 

 Mr D. Miller reports this as first recorded in 1920. 



Glyciphagus prunorum, Hermann {Glyciphagus domesticus, 

 De Geer). Common mite 



This cosmopolitan species has been known in New Zealand fi^om 

 the earliest days of European settlement. This is the cause of" Grocer's 

 Itch." 



Rhizoglyphus sp. 



Mr Howes informs me that an undetermined mite, belonging to 

 this genus, is commonly found attacking bulbs of various species (of 

 Narcissus}) in New Zealand.

Hcemaphysalis bispinosa, Neumann 



Some years ago ticks found in the north of Auckland were classified 

 as Ixodes ricinus. Later on, further specimens from the same locality 

 were sent to Prof. Nuttall of Cambridge, who advised the Agricultural 

 Department that they belonged to the genus Hcemaphysalis. More 

 recently, other specimens submitted to Cooper, a co-worker with 

 Nuttall, were classified as H. bispinosa. 



Dr Reakes thinks that as Ixodes ricinus is commonly found in 

 most temperate climates and is normally found in Britain, it is quite
