Records and Descriptions of Some Micronesian 
Psyllidae (Homoptera)^ 
Leonard D. Tuthill^ 
Dr. Teiso Esaki of Kyushu University, Fu- 
kuoka, Japan, has very kindly placed at my 
disposal the collections of Psyllidae made 
during his expeditions to the islands of 
Micronesia during the years 1936 to 1940. 
Only a few collections have been made in 
this area and undoubtedly many more mem- 
bers of this family remain to be discovered 
there. A few species which are widespread 
throughout the Pacific are represented in the 
material included. The remainder appear to be 
unnamed and probably represent forms en- 
demic to the island or group from which they 
were taken. All specimens bear the collector’s 
label of Teiso Esaki except where otherwise 
indicated. 
The figures have been prepared by Evan L. 
Gillespie of the Department of Zoology and 
Entomology, University of Hawaii. 
Mesohomotoma hibisci (Froggatt) 
Marianna Islands: Charanka, Saipan, Oc- 
tober 31, 1937. 
Caroline Islands: Paliker-Kolonia, Ponape, 
December 30, 1937, January 16, 1938, and 
July 16, 1939; Nipit-Kapiroi-Reitao, Ponape, 
July 21, 1939; Lelo, Kusaie, November 30, 
1937. 
This species is common on the young 
foliage of Hibiscus tiliaceus L. throughout most 
of the Pacific islands. Esaki notes that it is 
gregarious and that Arbela hibisci Esaki and 
Ishihara, a nabid bug, is found in association 
with it.

Tyora ornata (Kirkaldy) 
Caroline Islands : Kolonia, Ponape, Decem- 
ber 31, 1937; Toloas, Kutua, Truk, July 31, 
1939. 
A single male, without additional data, was 
taken in each of these collections. 
Leptynoptera sulfurea Crawford 
Caroline Islands: Kolonia-Jokaji, Ponape, 
January 9, 1938; Paliker-Kolonia, Ponape, 
January 16, 1938; Kolonia, Ponape, January 
17, 1938; Gatzapar, Yap, September 1, 1939. 
Palau Islands : Akarokuru, Peliliou, August 
12, 1939; Kaishar-Ngardok-Ngiwal, Babel- 
daob, August 15, 1939. 
Esaki reports this species as common in 
Palau, Yap, and Ponape, feeding on young 
leaves of Calophyllum Inophyllum L., gregar- 
iously. 
Arytaina clara (Tuthill) 
Ataenia clara Tuthill, Bernice P. Bishop Mus., 
Occas. Papers 17: 77, 1942. 
Caroline Islands: Kolonia, Ponape, De- 
cember 31, 1937, and January 1, 1938. 
One male and one female constitute the 
entire collection of this species, which is only 
known to occur on Ponape. The host plant 
is unknown. 
This and the following related species be- 
long to a large group of species known from 
the Orient which were assigned to Arytaina 
by Crawford. They are certainly quite far re- 
moved from the type species of Arytaina^ 
bemg much nearer Euphalerus. I am informed 
by G. Heslop-Harrison that he is presently 
revising the many-faceted group that Ary- 
taina has become. In the course of such
