PARATYPES (IM; 7F; 7P; llL; 6 individual 
rearings) all collected on Guadalcanal, as fol- 
lows: 3L(920-4) Tenaru, Mar. 15, 1945 (JNB, 
M. Cohen); 1FP(932-101) same data as ho- 
lotype and allotype; IMLP (941-32), 4FLP 
(941-31, 33, 34, 35) Kokumbona trail, 8 miles 
from north coast, April 8, 1945 (JNB); IF, 
lP(0-38) Tenaru, Sept. 28, 1943 (P. W. 
Oman); IF, 3L, Tenaru, Oct. 1944 (J. G. 
Franclemont) . 
Uranotaenia wysockii is named in honor of 
F. B. Wysocki in recognition of the many 
valuable collections he made on Guadalcanal. 
Variation 
The small series of adults from Guadal- 
canal, although reared from larvae collected 
in two widely separated localities in different 
plants, show no striking variations. The white- 
scaling of the abdomen is quite variable, and 
there is often a small basal median triangular 
spot on segments 2 to 4 encroaching upon 
the white markings. The head, thorax, and 
legs show very little variation in coloration. 
The variation in the chaetotaxy of immature 
stages is shown in Tables 1 and 2. Again 
there are no constant differences correlated 
with the different origin of the specimens. 
Individuals vary considerably in the branch- 
ing of the hairs but within the same range as 
the other species of Uranotaenia. The follow- 
ing larval hairs are unusually variable in 
branching: 4-C, 1-A, 0-P, 3-VIII, 2-X. There 
is more variation in the number of pecten 
teeth than in any other species studied. The 
pupal stage is about as uniform as in the 
other species. 
The material from Bougainville falls within 
the range of variation exhibited by the speci- 
mens from Guadalcanal without any special 
features or concentration at one or other ex- 
treme. 
Specimens examined: 9M; 25F; 9P; 22L. 
Individual rearings: 7 larval, 1 pupal. 
Taxonomic Discussion 
Uranotaenia wysockii is a very distinct and 
isolated species in the alboannulata-gsou^. 
This group has not been reported previously 
from the Australasian region. The Oriental 
species, U. alboannulata (Theobald, 1905) 
from South India, U. rutherfordi Edwards, 
1922, from Ceylon, and U. trilineata Leicester, 
I9O8, from Malaya are highly ornamented 
with light spots, lines, or bands on the pro- 
boscis (not in U. rutherfordi) and on the fem- 
ora, tibiae, and hind tarsus. U. wysockii 
agrees with these species in having pictured 
wings, a narrow light-scaled line from wing 
root around the front margin of the scutum, 
and the narrow light-scaled line across stp and 
apn connecting with the narrow orbital light- 
scaled line on the head. It differs from the 
Oriental species in the following combination 
of characters: proboscis dark-scaled; all fem- 
ora with an apical white knee spot only; 
all tibiae dark; hind tarsus white-scaled from 
basal third of segment 3; fore and mid tarsi 
cream-colored from basal third of segment 3. 
The immature stages of the Oriental species 
are not known. It is likely that they will be 
found in water collections in living plants. 
It is possible that U. nivipleura Leicester, 
I9O8, from Malaya is related to this group as 
it has the characteristic mesonotal scale bor- 
der and has been bred from pitcher plants. 
It is distinct from the alboannulata- gx.o\x^ in 
having dark wings and dark legs. The record 
of U. nivipleura by Barraud (1934: 76-77) 
from the Western Himalayas does not seem 
correct to me, nor Bohart and Ingram’s (1946: 
57) record from Okinawa. 
It is quite likely that members of the ^Z- 
boannulata-gsovc^ have been collected in the 
Australasian region and in the Philippines but 
have been misidentified as members of the 
nivipes- gsoM^. Both groups have the wing 
patterned in black and white, and the de- 
scriptions of the species of the nivipes- group 
are very misleading as to the nature of the 
light area around the lateral margin and front ' 
of the scutum.
