note on these leafhoppers, from examination of material in the 
British Museum: In looking through unworked material at the 
British Museum, I found three specimens of Perkinsiella Wirk. 
Two of the specimens are P. saccharicida Kirk., one from 
Merebank, Natal (C. P. V. D. Merwe, I-2-18), and the other 
from Mauritius (J. E. M. Brown). The third specimen is 
P. insigmis (Dist.) from Accra, Gold Coast (J. W. Scott Macfie, 
November, 1920). It is possible that P. saccharicida has been 
taken to Mauritius and Natal with sugar-cane. As no damage 
due to this insect has ever been reported from those regions, we 
must presume that parasites keep it in check. 
Allograpta obliqua (Say ).—Mr. Giffard reported that in July 
and August he captured a large series of both sexes of this 
Syrphid fly flying over the flowers of Sweet Alyssum at twenty- 
nine miles, Olaa, near Kilauea, Hawaii. This fly was recorded 
on February 5, 1920, by Timberlake (Proc. Haw. Ent. Soc., 
IV, 3, p. 456, 1921) as a new immigrant on Oahu. In October, 
1920, Swezey also reported it from Kauai. It has not yet been 
reported from other islands than the above. Other Syrphids 
taken at the same time at or near Kilauea were: Volucella obesa 
Fab., Eristalis tenar L,, HE. punctulatus Macq., and Xantho- 
gramma grandicorne Macq. E. tenax was very abundant every- 
where in the neighborhood, but the others were only seen 
occasionally. 
Scotorythra hyparcha Meyr.—Mr. Giffard remarked on the 
overabundance of this nocturnal moth at lights in the Kilauea 
region for the past four or five months. The verandahs and 
porches of the Volcano House and residences in the neighbor- 
hood have been overrun by this moth, possibly 90 per cent of 
the number seen nightly being males. At the hotel, the nightly 
flight was so annoying to guests that the servants were called 
upon to use the vacuum cleaner to sweep the ceilings and walls 
free of these pests. During twelve years and frequent visits 
he had never seen such an invasion of that or any other species 
of moth as occurred this summer. 
Kelisia paludum.—Mr. Giffard reported the collecting of a 
large series of both sexes and nymphs of this Delphacid on a 
patch of Juncus sp. near the’ beach at Naapoopoo, Kealakekua,
