DUNG BEETLES. 



Out of three hundred of these collected in Mittagong, New 

 South Wales, a little over one hundred reached us alive on 

 February 7, 1905. That very day they were released upon a 

 cattle ranch near Honolulu. Most of these beetles were what 

 are known as "tumble bugs," because of their habit of rolling 

 dung into spherical pellets and carrying them down into a 

 previously made burrow in the ground. It was hoped that if 

 they increased in sufficient numbers they would disintegrate 

 cattle droppings before the hornfly has had opportunity to 

 develop in them. 



Another consignment of these insects reached us on Febru- 

 ary 28, 1905, but most of these were dead and the few survivors 

 died soon afterwards. 



PAEASITES OF DUNG FLIES (Diptera). 



A large number of dung larvae and pupae was collected by 

 Mr. Koebele in Condong, near Sydney, and reached us in good 

 condition on February 28, 1905. A large number of parasites 

 subsequently issued from these and two strong colonies were 

 located on ranches on Oahu. On two occasions these were 

 visited later, but no evidence was found to indicate that either 

 the parasite or the dung beetle were established. 



ASIATIC LADYBIRD (Chilocorus similis, Rossi).* 



Dr. Nicholas Russel of Olaa, Hawaii, has long been one of 

 the most intelligent and valued correspondents of the Board's 

 Entomological Division. Recently he went to Japan. At the 

 request of Mr. Craw, who supplied him with letters of intro- 

 duction to entomologists in Japan, he undertook to introduce 

 into the Territory what beneficial insects he may come across. 

 On the 8th of September this office received from Dr. Russel a 

 colony of Asiatic ladybirds. In the absence of suitable tubes 

 the Doctor made ingenious use of ordinary lamp chimneys. 

 These he filled with food for the ladybirds and with it placed 

 as many pupae and adults of the ladybirds as he could find.
