Hilgendorf. — A Lint of N.Z. Rotifera. 267 



Bombyx. 



We have here imported three bumble bees, B. virginalis, 

 B. hortorum, and B. hortorum var. harrisellus. While making 

 some investigations into the harm or good that these bees do 

 to the bean-crop I made the following observations that I 

 think worth recording : Of sixteen specimens of B. virginalis 

 that I watched, the whole sixteen bit through the base of the 

 flower to get at the nectar. Of thirteen specimens of B. hor- 

 torum and of seventeen of B. hortorum var. harrisellus, the 

 whole number climbed in through the mouth of the flower 

 and got at the nectar by the legitimate means. It thus 

 appears — and, indeed, it would appear from the structure of 

 their probosces — that, as far as the bean goes, B. virginalis 

 is useless or harmful, while the other two are useful. 



Art. XXVII. — The Rotifera of New Zealand : a Revised and 



Expanded List. 



By F. W. Hilgendorf, M.A., B.Sc. 



[Read before the Philosophical Institute of Canterbury, 26th November, 



1902.] 



The object of this paper is to make numerous corrections in 

 the " Contribution to the Study of the Eotifera of New Zea- 

 land," which appeared in the " Transactions of the New Zea- 

 land Institute," vol. xxxi., p. 107, and at the same time to 

 add to the list the names of some species that I have found 

 since writing my last paper. The corrections referred to have 

 been made largely at the suggestion of Mr. C. F. Rousselet, 

 Curator of the Royal Microscopical Society, and partly as the 

 result of my own further observations.
