near his beach house at Malaekahana, near Laie, Oahu, almost 
defoliated by a small, green caterpillar. He exhibited a series 
of this moth which was captured about the tree by Dr. S. C. 
Ball, although no caterpillars were seen at the time. 
Niphidiopsis lita Heb.—A female specimen of this Tetti- 
goniidae was taken by Mr. Fullaway in Honolulu, September 
11, 1923. Hitherto it has been known only from the town 
of Hilo, and vicinity, Hawai, where it appeared first in 1919. 
Nysius delectus White-—Mr. Giffard exhibited a large num- 
ber of these insects, which had been taken at large by Mr. 
Irwin Spalding on the ridge near Green Peak, overlooking 
Nanakuli Valley, on the Waianae Range, Oahu. Mr. Spalding 
reported that, in the latter part of September, 1923, while 
tramping along the thickly vegetated ridge on its windward 
crest during heavy wind and showers, he noticed that the fronds 
of tree ferns, mokehana, and other vegetation, when disturbed, 
caused enormous flights of these heteropterous insects, so 
much so, that their contact with the face and clothing became 
annoying. These facts caused Mr. Spalding to investigate, and 
he reported that certain of the vegetation, more particularly 
the ferns, contained large masses of these insects which, in 
spots, had assembled in millions. As an example he claims that 
on a single frond of tree fern he and his companions observed 
an assemblage of these insects over one inch thick by three 
inches long and two inches wide, from which he captured a 
handful of Nysiuws of which this exhibit forms a part. Mr. 
Spalding further stated that this unusual flight continued for 
half a mile on the ridge and that the insects appeared to be 
quite undisturbed by the wind and rain, but flew in myriads 
just as soon as the bushes were disturbed. No cause for the 
unusually large numbers was advanced by Mr. Spalding and 
no perceptible damage to the vegetation was observed by him. 
Mr. Fullaway reported a similar occurrence at Waikii, Parker 
Ranch, on corn, thickly congregated but not bunched in layers. 
Mr. Bryan had observed a number on Chenopodium bushes on 
Necker Island, all bunched up in several layers.
