monstrous horned beetle handed him by Mr. William Weinrich, 
who had collected it on a tree in Guatemala in August of this 
year. 
Oligota sp—Mr. Swezey exhibited a tiny Staphylinid beetle 
probably of this genus, which he had found feeding on the 
sugar-cane leaf-mite and its eggs in the cane fields of Oahu 
Sugar Company, and also at the Sugar Planters’ Experiment 
Station grounds. The larvae were also found feeding on the 
mites. This is apparently the first record of this immigrant 
beetle in the Islands. A similar beetle occurs feeding on red 
spiders in California. It may turn out that this is the same 
species. The mite that they were feeding on here is 7etrany- 
chus exsiccator, the cane leaf-mite occurring in Java. Appar- 
ently this has never been recorded in Hawaii, though it has been 
known for a long time that mites were occasionally found on 
cane-leaves. 
Ereunetis flavistriata—Mr. Swezey mentioned that, while in 
San Francisco in August at the Plant Inspector's office, he 
inquired about the Hyposmocoma sp., which had been reported 
as occurring on coconuts from Honolulu, as per printed reports 
in the California Monthly Bulletin. A more recent identification 
had been made by Mr. Busck as Ereunetis sp. On being shown 
a specimen of the moth concerned, Mr. Swezey was able to iden- 
tify the species as Ereunetis flavistriata, the sugar-cane bud- 
moth, whose larvae are found also on banana bunches, pine- 
apples, and various other plants, chiefly feeding on the dead 
tissues. 
Heterospilus prosopidis—Mr. Swezey reported rearing this 
Braconid quite plentifully from Bruchus chinensis in pigeon 
peas at Kaimuki, September 16, 17, 1922. The peas had become 
infested by the bruchids while still on the bushes. Males pre- 
dominated in those reared, there being nine males and three 
females. 
Pediculoides ventricosus——Dr. Illingworth stated that kero- 
sene was very helpful in relieving the irritation caused by the 
bites of this mite on the bodies of human beings. 
Pseudaphycus sp—Mr. Fullaway exhibited specimens of this 
Encyrtid, introduced from Mexico in April and May, 1922. It
