 broader than the abdomen. Whole body with numerous short 

 stiff bristles, these occurring in single transverse rows on the 

 abdominal tergites. Ovipositor very short. Postmarginal vein 

 much longer than marginal, the stigmal slightly shorter than 

 marginal. Fore tibiae resembling those of male, about one-third 

 the length of their femora, but the tarsi normally 5- jointed. 

 The hind tibiae about one-half the length of their femora, and 

 at the inner apical angles with a stout spine and a minute 

 bidentate process; hind tarsi very long, the first joint longer 

 than the 2 following; the second to fourth subequal; the fifth 

 about one-half the length of the first. Length, 2 mm. 



Fig. 3. Some anatomical details of fig insects. A, head of Philotrypesia similis (0.6 by 0.8 

 mm.) ; B, head of Philotrypesis collaris, the spined extensions shown at angles 

 of occiput being below (size of head, 0.95 by 1 mm.) ; C, head of Philotrypesia 

 ashmeadii (0.55 by 0.7 mm.) ; D, hind tibia and tarsus of Blastophaga nota; E, 

 fore tibia and tarsus of Blastophaga nota; F, hind tibia and tarsus of Sycoryctea 

 philippinenais. 



This blastophaga is the normal inhabitant of the gall flowers 

 and the active caprifier of Ficus nota at Los Banos, P. I.
