DISEASES OF THE DATE PALM. 137 



For more detailed information regarding this pest, see 

 (a) Memoirs of the Department of Agriculture in India, Ento- 

 mological Series, Volume IT, No. 10, Life-Histories of Insect 

 Pests, III, December, 1911, by C. C. Ghosh. 



(b] Indian Insect Life by Lefroy, and 



(c) Fauna of India, Vol. Coleoptera Lamell, Part I, 

 from which the subject-matter for the above note has been taken. 

 The coloured illustration No. 47 at page 1346 has also been 

 kindly supplied by the Imperial Entomologist to the Government 

 of India and is from (a) above mentiozied. 



I have already found two specimens of a beetle identified 

 for us by the Imperial Entomologist as Oryctes nasicornis. One 

 of these two was found in Dalhousie in early July, 1915, and the 

 other in Lyallpur a few weeks later. This beetle has a horn on 

 its head and might be mistaken by many people for Oryctes 

 rhinoceros. There are other beetles also which might be confused 

 with it ; therefore likely specimens should be sent to the 

 Agricultural Department for identification. 



Scale Insects (Coccidese). 



95. Scale Insects (see illustrations Nos. 49 and 50, pages 

 1366 and 136c) are usually to be found in local date trees in the 

 date-growing districts of the province. They are most commonly 

 found on the leaflets and on the main axes of the leaves, in 

 the angles at the bases of the leaflets. When few, they are 

 usually restricted to the leaflets on the shady side of the trees, 

 or such places. They have attacked the imported trees much 

 more vigorously than the local ones ; indeed they have hindered 

 the growth of the imported trees a good deal in some cases. 

 At Lyallpur, at Multan, or Muzaffargarh, in some years they 

 have even attacked the ripening fruit bunches spoiling the 

 appearance of the fruits. In no case has any of our imported 

 trees been killed by the pest however. It appears to waken 

 up with the rains, increase towards winter, remain evident on 

 the trees all winter, and then decrease as the temperature 

 increases till the rains come.
