Triton Oder us varipes n. sp. — J Length 4 mm. — Face finely reticu- 

 lated, the areola? shining, metallic vari-colored. cbamelion fashion, the sculpture 

 gives the face a scaly appearance under a low power lens, clypeus longitudinally 

 finely striate, occiput finely transversely striate. Mandibles broad, armed with 

 four teeth on the truncate apex, the three innermost teeth close together, the 

 outermost tooth separated from the others. Flagellum sericeous. Dorsal aspect 

 of the thorax sculptured much like the face, finer laterally than medially, duller 

 and darker. Mesonotal furrows originating antero-laterally curved inward, 

 hardly reaching to the middle of one-half of the dorsulum. Wings hyaline, 

 submarginal nervure with stiff bristles as long as the distance between one and 

 another, stigmal vein clubbed, the knob with a small appendage, the vein itself 

 nearly as long as the prolongation of the marginal vein on the border of the wing 

 beyond the insertion of the stigmal vein. Abdomen acuminate, elongate, smooth 

 and shining above, dark metallic minutely sculptured ventrally, and keeled at 

 base, ventral slit fringed with black hair, the apical segment sparsely ciliate.
