Haskell. — Note on an Aphidian Insect. 13 



The cartilaginous portions of the anterior cornua of the hyoid are restored, 

 but the sternal ribs are entirely omitted, as I can find no figure of them, 

 except one of Turner's,* showing the relations of the first sternal rib to the 

 sternum in Balcenoptera sibbaldii. Only one complete set of carpals could 

 be made up. Each of these was divided tangentially, and half used for 

 each manus by being partially imbedded in the cement used to represent 

 the continuous carpal cartilage. 



The skeleton is suspended in the centre of the Museum from girders of 

 railway-iron passing between the capitals of the columns supporting the 

 upper gallery. I am greatly indebted to Mr. W. N. Blair, C.E., Engineer- 

 in-charge for the South Island, for having kindly furnished me with an 

 extremely suitable design for these supports. 



The articulation of the skeleton has been very successfully done by my 

 second assistant, F. J. Bourne, who also designed the whole of the iron- 

 work, with the exception of the girders. 



I have to thank my friend and colleague Professor Scott, M.D., for 

 having made the drawings from which figures 1, 2, and 3 are taken.

Plate VII 



Some four or five years ago the imported pine trees in this country began 



to be attacked by a " blight," (to use the popular term) which has since 



increased to a somewhat alarming extent throughout the colony, at least in 



Wellington, Nelson, and Canterbury. The trees most subject to this pest 



appear to be Pimis halepensis, P. insignis, and P. silvestris. The general 



appearance presented is that of a white, mealy or cottony, fluff thickly 



coating the twigs of the tree but not extending far along the leaf-tufts. 



These last, however, soon become dry and brown, as if scorched, and
