close (0.09 mm.) to the base of the segment. 
The spermathecae are distinctive in shape 
(Fig. 31^). They are apparently three in num- 
ber but one specimen studied had four. 
Type male, allotype female, and 115 para- 
types from Atherton Tableland, Queensland, 
ex 'Planchonella sp.(.^), Nov.-Dee., 1949; 30 
paratypes from Julatten, Queensland, ex 
Amorphospermum antilogum, and 2 from Mow- 
bray River, Queensland, ex Capparis lucida, 
Feb., 1950. 
Type, allotype, and a series of paratypes 
are in the United States National Museum 
collection. The remainder are deposited in 
the following collections: Board of Agricul- 
ture and Forestry, Honolulu, T. H.; Bishop 
Museum, Honolulu, T. H.; Hawaiian Sugar 
Planters’ Association, Honolulu, T. H.; 
Australian Museum, Sydney; University of 
Hawaii; Dr. H. K. Munro, Pretoria, South 
Africa; Dr. M. Hering, University of Berlin; 
and Mr. J. E. Collin, Newmarket, England.

This species is readily distinguished by the 
large spots in cell R5, the paler brown macula- 
dons in the wings, and the different colora- 
tion of the abdomen. In general details it will 
fit the above description of R. confusa n. sp. 
The wing maculation is as given in the above 
key and shown in Figure ^2a. The first two 
abdominal segments are yellow to cream. The 
third is yellow in the middle, this mark ex- 
panding posteriorly to cover most of the hind 
margin; a wedge of black extends on each 
side from the lateral margins about one-third 
the distance across the anterior margin. The 
fourth and fifth segments of the male are 
entirely subshining black. The female has a 
narrow yellow mark across the front margin 
of the fourth tergum. Ovipositor: Shining 
black; the visible portion is not quite as long 
as terga 4 plus 5. The extended ovipositor is 
almost identical with that of confusa. No 
satisfactory specific characters have been 
found in the ovipositors. That of pornia 
(Fig. 32^-c) appears to have more distinct 
dentations on the rasper, the longitudinal bars 
in the basal part of the inversion membrane 
appear more heavily sclerotized, and the 
piercer is more straight sided; these may be 
individual variations. 
Length: Body, 5.0 mm.; wings, 5. 5-6.0 mm. 
TYPE LOCALITY: Port Stephens, New South 
Wales. , 
Type in British Museum. 
Specimens were received from Mr. Krauss 
from Gosford, New South Wales, ex "feijoa 
fruit,” Apr., 1950 (Krauss); and Narara, New 
South Wales, "trapped,” Nov. 29, 1933 
(C. P. Hely).
