apicalis de Meijere which differs by having a 
large apical spot in the wing, siiort yellow 
postsutural stripes, and by lacking infuscation 
over the cross veins. 
Length: Wings, 5. 5-6.0 mm. 
TYPE LOCALITY: Elores. 
Type in the Deutsches Entomologisches 
Institut. 
We have not seen this species. 
Dacus (Striimetd) propinquus n. sp.

This species resembles D. dorsalis very close- 
ly and can be satisfactorily separated there- 
from only by the structure of the ovipositor. 
The costal band is broader than in typical 
dorsalis but is just slightly more developed 
than in dorsalis var. occipitalis (Bezzi). The 
palpi in both sexes of propinquus appear to be 
comparatively more slender and parallel sided 
than in dorsalis, and the cubital cell is con- 
sistently shorter in all the specimens on hand; 
the narrowed portion of the cubital cell, com- 
pared to the portion from the apex to the wing 
margin, is about 37:20 (marks on our mi- 
crometer) in the female and about 38:15 in 
the male, as compared to 31:33 in the dorsalis 
female and 35:18 in the male. We do not feel, 
however, that these characters can be relied 
upon; they appear to be quite variable when 
studied through a long series of specimens. 
There appear to be some slight differences 
in the male genitalia. The peculiar trilobed 
apex of the ovipositor will distinguish this 
from all known related species. This is the 
first time we have seen this character in a 
Dacus {Strumeta) except for D. froggatti (Bezzi) 
and D. latifrons (Hendel) ; in this respect 
propinquus resembles D. {Zeugodacus) trimacu- 
latus n. sp. (Fig. 2^d). 
In the senior author’s preliminary reports 
(unpublished) on the fruit flies which were 
collected in Borneo in connection with the 
biological control of the Oriental fruit fly 
project, these specimens were confused under 
dorsalis. After more critical examination they 
were found to be a distinct species.

b, extended ovipositor; c, apex of piercer. 
FEMALE. Head: Front about 1.75 times as 
long as wide and with indistinct brownish 
spots at the base of the frontal bristles. There 
are two pairs of inferior fronto-orbital bristles 
and one pair of superior fronto-orbitals. The 
facial spots are large and oval in shape. The 
third antennal segment is slightly longer than 
the face; the hind portion of the occiput 
varies in coloration from entirely yellow rufous 
to brownish. Thorax: Mesonotum predom- 
inantly black; lightly gray pollinose; the post- 
sutural yellow vittae are comparatively broad 
and extend to just beyond the inner supraalar 
bristles; the supraalar areas to the side of the 
yellow vittae are black. Scutellum all yellow 
except for a narrow band of black across the 
base. The metanotum is predominantly black, 
slightly reddish in the median portion. Legs: 
Femora chiefly yellow to rufous; the front 
pair have a black spot on the upper apical 
portion. The tibiae are reddish brown; the 
tarsi are yellow except for the brownish apical
