Fig. 24. Dacus {Strumeta) tryoni (Froggatt): a, ovi- 
positor, full length; b, apex of ovipositor. 
positor: Moderately short in in situ specimens; 
the visible portion is about one and one-half 
times longer than the fifth tergum. The ex- 
tended ovipositor (Fig. 2Ad) is about 4.0 mm. 
long. The piercer measures about 1.27 mm. 
long by 0.19 mm. at its widest point. The 
setae are located about 0.09 mm. from the 
apex of the piercer (Fig. 24^), this distance 
being comparable to about four times the 
length of the plate bearing the setae or four 
times the length of the longest setae. The 
apex of the oviduct is about 0.26 mm. from 
the tip of the piercer. The inversion mem- 
brane is about 1.5 mm. long by 0.3 mm. wide 
at its base. The scales of the rasper are broad 
and rather blunt and extend to within 0.45 
mm. from the base of the segment. The basal 
segment is about 1.2 mm. long by 1.07 mm. 
across its hind margin. The spiracles are 
located about 0.28 mm. from the posterior 
lateral margin of the segment. 
Length: Body, 6. 0-7.0 mm.; wings, 5.0- 
6.0 mm.

Wales.
