30 Second Report on Economic Zoology. 



" big-bud " on tliein. No bushes are grown more than three years, 

 only the stools are kept for the cuttings, of course being cut back 

 every year. 



Mr. E. J. \^'heler, of Alnwick, Commissioner of His Grace the 

 Duke of Northumberland, tells me he has no " big-bud " in his 

 garden, and states that he had little doubt that clean stock could be 

 got in tlie neighbourhood if desii^ed. 



Mr. A. T. Gillanders, of the same district, writes : " I have not 

 seen a single specimen on black currant during the five years I have 

 been here. Further enquiry has shown Northumberland to be 

 practically free. Mr. Wlieler writes me later that the Duke of 

 Northumberland's forester assures him that Northumberland is 

 practically clear of the mite. 



Information obtained in Ireland has shown the " big-bud " to be 

 comparatively scarce, particularly in Armagh and co. Down. I have 

 seen little in Devon or Hampshii'e. Further enquiries have ceased 

 pro tern., owing to the Eoyal Agricultural Societies' zoologist, 

 Mr. Cecil Warburton, reporting on this subject after touring in parts 

 of Great Britain. 



A Red Spider {Tenuipalpus) on Fruit Trees. 



Numerous enquiries have been sent concerning a Eed Spider 

 which is very abundant on fruit trees. The round globular eggs are 

 very noticeable in winter and spring in the axils of the buds and 

 twi<^s. The eggs hatched out in March and April, and specimens 

 were sent at once to Mr. Albert Michael for identification. 



The specimens were identified by Mr. Albert Michael as species 

 of the genus Tenuipalpus — probably T. glaber of Donnadieu — but 

 it is not possil;)le to be certain of the species from immature speci- 

 mens. 



This species can easily be hatched out from the round bright red 

 eijgs which thickly encrust the smaller stems of fruit trees. I have 

 failed to trace any damage caused by these acari, even when they 

 have swarmed over the trees. They reach the mature state in April 

 and then disperse. From a series of observations I am sure they 

 feed upon the spores of various fungi and lichens growing on the 

 frait trees. 



The Wood Leopard Moth. 



The Wood Leopard " Borer " is the larva of the Wood Leopard 

 Moth (Zeuzera sescidi). It has been sent from Eynsford and Goud-
