toward the middle of the flagellum where the joints are about twice as long as 

 thick; joints near the apex shorter and not quite so thick. Seen from the 

 side the upper surface of the thorax is evenly arcuate. Mesonotum with the 

 coriaceous sculpture characteristic of recent species of Limnerium. Metano- 

 tum with the first and second lateral areas separate; the first and second pleural 



areas apparently con- 

 fluent, but the third sepa- 

 rated from the second. 

 Abdomen of the usual 

 form; the petiole gradu- 

 ally thickened, then 

 slightly narrowed just be- 

 fore the tip; three times 

 as long as high. Oviposi- 

 tor as long as the abdomen 

 from the tip of the second segment. Legs stout, especially the hind femora; 

 hind tarsi apparently pale at the base. Stigma and veins piceous; stigma 

 oval-lanceolate, rather narrow; marginal cell wide, the first section of the 

 radius a little more than one-third the length of the second. Areolet 

 large, oblique, rhomboidal, narrowed above to a point but not petiolate.

This is a typical species of Limnerium, quite similar to some of the 

 living forms of this very extensive genus. 



No fossil representatives of the Paniscini have previously been 

 discovered, but I have found species belonging to two living genera, 

 Absyrtus and Parabates in the present collection, and possibly a species 

 of a third, Opheltes. 



Absyrtus decrepitus, sp. nov. (Fig. 61.) 



Sex? (probably a female). Length 7.25 mm. Black, the abdomen beyond 

 the first segment brown with pale bands on the bases of the segments. An- 

 tennae scarcely preserved, but they were 

 probably quite stout and with the joints 

 near the middle of the flagellum quadrate 

 or slightly longer than thick. Mesonotum 

 and pleurae smooth; metathorax areo- 

 lated, at least near the tip. Abdomen 

 long and of nearly even width beyond the 

 first segment which is twice as long as 

 broad and finely longitudinally rugulose; 

 second rapidly widened, as long as broad at the tip; third to sixth
