Some other parasites and predators liave also been handled 

 in tlie insectary. A Dung Fly parasite (Muscidifurax vorax)y 

 brought by Prof. SilvestTi from South Africa, has been produced 

 by the thousands (76,279 at the close of 1913), and liberated in 

 stables about Honolulu and on all the large cattle ranches on the 

 Islarid. Two other Dung fly parasites (Pteromalus sp. and Spa- 

 langia sp.) brought by the writer from the Philippine Islands in 

 the early part of 1914, were multiplied in large numbers and 

 distributed in similar places, and a coccinellid beetle (8cynnus 

 hipunctatus) feeding on mealy bugs was brought at the same 

 time and liberated at various places around Honolulu. Later on, 

 through an arrangement made with Prof. Silvestri, some work 

 was undertaken on Horn Fly enemies in I*\^orth Africa, and as 

 a result of this the insectary was in receipt during the six 

 months from January to July of various consignments of 8ia- 

 phylinid beetles, wdiich are predatory on Dung Fly larvae and 

 pupae. These beetles came mostly in very poor shape but all that 

 were in a living condition were liberated in cow pastures where 

 the conditions were suitable for their propagation. 



I have recently had tables prepared to indicate the extent of 

 the distribution of the different fruit fly and dung fly parasites, 

 and an examination of these, tables shows that good sized colonies 

 of the parasites have been liberated in the following places :
