“A New Hawaiian Delphacid (Homoptera).” 
BY F. MUIR. 
NOTES AND EXHIBITIONS. 
Ischiogonus sp.—Mr. Muir exhibited specimens of this 
parasite of the Australian fern weevil (Syagrius fulvitarsis), 
sent by Mr. Pemberton from New South Wales, Australia. 
Cocoons of the parasite arrived on May 21, and since then 
4 females and 30 males have issued. Most of them have been 
liberated on Mt. Tantalus, where there are Sadleria ferns 
infested with the weevil. 
Mitrastethus bituberculatus and Dryophthorus distinguen- 
dus.—Mr. Ehrhorn exhibited these two weevils obtained from 
the wood of propagating boxes. The former is a New Zealand 
beetle and was found in the sound wood; the latter was in‘the 
retted wood. 
Vanessa callirhoea—Mr. Swezey exhibited a set of wings 
of this butterfly sent him by Mr. Charles E. Hempel from 
Funchal, Madiera Islands. They have markings more nearly 
like Vanessa tammeamea than has any other species. Each 
species is similarly confined to an isolated group of islands, 
which are separated by many thousand miles. 
Plaiyedra goss\piella—Mr. Swezey exhibited a specimen of 
the pink boll-worm moth reared from the seed capsule of 
Flibiscus youngianus collected by Mr. McEldowney, April 1, 
1921, on the ridge at Waimalu, Oahu. 
Vanessa tammeamea.—Mr. Swezey stated that Mr. Caum 
reported to him the finding of 6 chrysalids of this butterfly 
attached to the leaves of the awa (Piper methysticum) in 
Pukoo Valley, Molokai, February 15, 1921. Butterflies issued 
from 5 of the chrysalids, and a Chalcis obscurata from the 
remaining one. This is the first record of this as a host for 
this parasite. 
Frontina archippivora—Mr. Swezey reported rearing this
