broadly shallowly 2-lobed. Antenna very small for so large a 

 head, the small sockets remote, nearer to bases of mandibles and 

 to front margin of head than to each other; scape a little over 

 4 times longer than wide, pedicel and flagellum together not as 

 long as scape, the flagellum very pale in color, 8- jointed. Face 

 deeply gradually excavated and finely sparsely transversely 

 striolated. Prothorax as broad as head, with 2 large bristles 

 on each lateral margin and 2 near the hind border; meso- and 

 metathorax taken together shorter than the pronotum and be- 

 coming much narrower. Abdomen very small, narrower than 

 metathorax, and rapidly narrowing to tip. Male claspers long 

 and stout, with 3 stout black teeth at each tip. Fore legs to the 

 tarsi, darker brown, remainder of legs pale yellow. Legs nor- 

 mal for Philotrypesis, but the lobes of first and second joints 

 of hind tarsi with 2 long spines each, these joints together 

 equaling the remainder of the tarsus in length. Body and legs 

 entirely without the dense vestiture of stiff short bristles pos- 

 sessed by P. similis and P. ashmeadii. 



Female. — Flagellum, top of head, meso- and metanotum, entire 

 dorsum of abdomen, and ovipositor, blackish ; remainder of body 

 including pronotum, yellowish. Length of body without ex- 

 tended segments, 3.5 mm. ; of first extended segment, 2 mm. ; of 

 second, 0.5 mm. ; of ovipositor, about 4.5 mm. More similar to 

 P. ashmeadii than to P. similis, having 3 ring-joints in the 

 antennae, and very similar in other characters. 



Occasional in gall figs of F. nota at Los Baiios, P. I. Probably 

 parasitic on Blastophaga. It is very remarkable that 3 such 

 similar species of Philotrypesis should occur in the same figs 

 together, but although the females are somewhat alike the males 

 are very distinct.
