of the piercer. The setae are situated just be- 
fore the apex of the piercer; the distal two 
pairs are strongly developed and extend well 
beyond the tip of the piercer (Fig. 2'bd)\ the 
proximal pair is small and inconspicuous.

This species appears to be nearly free of 
parasites in the areas covered in this report. 
Of the many thousands of specimens which 
were sent in by the collectors in the field only 
20 specimens of Opius makii Sonan were reared 
(from Mindanao, Philippine Islands, D. ha- 
geni, ex Trichosanthes sp..^). Opius angaleti 
Fullaway may possibly parasitize this species; 
it has been reared from fruits (in Borneo) 
infested with both hageni and Callantra smier- 
oides Walker.

This species was redescribed by Perkins. 
The original description is very brief, and it 
is possible that Perkins’ male specimen from 
Malaya may be quite a distinct species from 
Macquart’s limbipennis. It agrees with the orig- 
inal description in having the face shining 
black with yellow margins. There are no other 
details in Macquart’s description which are of 
much value in placing the species. In the 
event that these should prove to be distinct 
species, Perkins has proposed the name atri- 
facies for his specimen. 
Dacus limbipennis (as defined by Perkins) 
resembles D. termini fer Walker because of the 
black face. It is distinguished from the latter 
by the presence of three postsutural yellow 
vittae on the mesonotum. 
Length: Body, 5. 5-6.0 mm.; wings, 5.0- 
5.5 mm. 
TYPE locality: Java. 
Type in Paris, according to Bezzi (1913: 74).
