Abdomen, as seen from above, conic-ovate, beneath compressed and strongly, triangularly cari- 

 nate, as long as the thorax, segments 2-4 about equal, united not longer than the first, meta- 

 thorax very short, smooth, but with a median carina, the spiracles rounded. 



Tropidogastra Ashmead, g. nov. (type T. arizonensis Ashm.). 



5. Antennae 13-jointed, with tivo ring-joints, inserted on or near the middle of the face 6 



Antennae 13-jointed, with two ring-joints, inserted just above the clypeus Anogmus Forster. 



6. Metathoracic spiracles small, rounded ; flagellum long, filiform ; abdomen oblong-oval, fully as long as 



the thorax ; marginal vein slender, longer than the stigmal vein Eoptrocerus Ratzeburg. 



Metathoracic spiracles large, oval ; flagellum shorter, subclavate ; abdomen oblong-oval, a little longer 

 than the thorax, subcarinate beneath towards base ; marginal vein stout aud not longer than the stig- 

 mal vein with its knob Ur'ella Ashmead. 



Tribe IT. Merisini. 

 This tribe is at once separated from the Isoplatini by having incomplete, never 

 complete, mesonotal furrows, the farrows at the most being indicated only 

 anteriorly.

 the second segment (first body) occupying fully one half or more of the whole surface.
