The gladiolus thrips ( Taeniothrj-ps gladiol i If. 4 S. ) first came to 
to the attention of the entomologists in Hawaii in November. In t*w 
florists' gardens in several parts of Honolulu the infestation was so 
severe as to ruin the entire crop of gladiolus. Examination in other 
districts showed this thrips to be widespread already, although not 
all gardens were infested. Immediate investigations on Maui and Hawaii 
revealed the pest to be present there also. 
The first positive evidence that the oxwarble fly Hypo derma line- 
^taE DeVill. is established in Hawaii was obtained in November, when the 
entomologists' attention vas called to perforated hides freshly removed 
from cattle at the slaughter-house in Honolulu. The cattle were from a 
large ranch on the island of Hawaii, and were said to be island-born. 
Many times warbles have "been found in the hacks of imported dairy cows 
and breeding stock, and they were treated for removal of warbles. The 
men at the slaughter-house said that they had previously found perfora- 
tions in hides, and also the warbles, but at this time they were more 
numerous than they had ever seen them. Sometimes there were as many as 
10 or more in a single hide. 
The horn fly (Haematobia_ i rritans L. ) continues to "be a very trouble- 
some pest on the cattle of the ranches as well as on dairy cows. It breeds 
continuously the year round and is abundant at all times.
