apical joint" slender, longer than the second and third com- 

 bined, ungues o£ the hind tarsi almost as long as the apical 

 joint of the tarsi, the other tarsal ungues small.

This belongs to the section of the genus in which the 

 terebra is not exserted and is recurved. In this section the 

 third and fourth joints of the flagellum arc short, their com- 

 bined length l#ing scarcely if at all greater than that of the 

 second joint. In the group of rufa and humeralis i in which 

 the terebra is straight and exserted, the third and fourth 

 joints of the flagellum arc each almost aa long as the second. 

 Except in the presence of two discoidal cells instead of one, 

 this species and its allies nearly approach typical Pseudo- 

 foenus from New Zealand. American and Australia] 

 with the neuration of Pseudofcenus are slender insects much 

 more nearly allied to Fuenus.

This belongs to Flyptiogaster, having- two discoidal cells 

 and the cubital vein springing from the basal nervine. A 

 specimen from Darwin's collection, almost certainly the type, 

 is in the British Museum, but the abdomen is lost. 



Uyptiogaster nitidiuscula, sp. n. 



$ . Brunneo-ferruginea ; mesonoto nigro-suffuso, punctato, haud 

 rugose; alis hyalinis, venis fuscia ; terebra recurvata, haud 

 exserta. 



d . Femime similis. 

 Long. 8-10 mm. 



? . Very similar to II. incequahs, described above, but 

 differs in the following points : — Less robust : front much 

 less convex in the middle, the carina not as strongly raised, 

 the front sparsely punctured. Second joint of the flagellum 

 three and a half times as long as the first, as long as the third 

 and fourth combined. Mesonoturn deeply and strongly 

 punctured, not rugose, the punctures distinctly separated. 

 Ungues of the hind tarsi small as in the other tarsi, hind 

 metatarsus a little longer than the three following joints 

 combined, all the joints normal, longer than broad, only 

 slightly asymmetrical.
