BRUES: PARASITIC HYMENOPTERA.

the side it appears to be rather evenly curved and swollen at the apex, with the 

 spiracles at the apical third. Seen from the side the body of the abdomen is 

 rather slender, with a stout ovipositor that projects beyond the tip by a dis- 

 tance equal to one-third the length of the abdomen. Wings very faintly 

 brownish, more distinctly so below the stigma. Stigma and veins pale 

 fuscous, the former broad and almost subtriangular. Areolet of only moder- 

 ate size, pentangular in position but open behind. Discocubital vein slightly 

 and evenly curved; submedian cell slightly longer than the median. 



One finely preserved specimen seen in lateral view.

I think this is a true hemiteline although the abdominal petiole at 

 first sight appears to be too stout and evenly curved. I am convinced, 

 however, that this is due to twisting and splitting during the course of 

 fossilization. 



Hemiteles obtectus, sp. nov. (Fig. 29.) 



Female. Length 4 mm. Black, the abdomen shading to fuscous apically. 

 Legs blackish, the hind coxae, trochanters and tibiae, except apex, brownish. 

 Wings tinged with brownish, stigma and veins pale fuscous. Antennae 

 rather stout, the joints of the basal part of the flagellum quadrate. Mesono- 

 tum smooth and shining. Metanotum areolated, at least on the sides. Abdo- 

 men sharply petiolate, the 

 petiole only gradually en- 

 larged behind (in lateral 

 aspect) and bent down near 

 the tip. Remaining segments 

 of nearly equal height, the 

 ovipositor not distinctly pre- 

 served to the tip, but appar- 

 ently nearly as long as the 

 abdomen exclusive of the 

 petiole. Legs stout, unusu- 

 ally so for one of the Hemitelini, the hind femora and tibiae considerably thick- 

 ened. Wings with broad, subtriangular "stigma ; radial cell short and broad, 

 the first section of the radius only one-third as long as the second. Areolet 

 open but pentangular in position. Basal nervure distinctly curved inward, 

 the submedian cell a little longer than the median. 



Three specimens, one with reverse, all without doubt belonging to 

 the same species.
