 Koebele, of Honolulu, and others. 



A few species are also included from China, Formosa, Trong-, Lower 

 8iam, etc. Six genera and seventy-three species are described as new 

 to science. 



Parts land II of this series of papers were published in the Journal 

 of the New York Entomological Society for 1904, and treated of the 

 superfamilies Sphecoidea, Vespoidea, Proctotrypoidea, Cynipoidea, 

 and Chalcidoidea. The present paper treats of the superfamily 

 Ichneumonoidea.

MATSUMURAIUS, new genus. 



This new genus belongs to the tribe Joppini, and will fall in mj- 

 table of genera, Classification of the Ichneumon Flies, 1900, page 15, 

 next to Eccoptoscvrge Kriechbaumer, but may be easily separated by 

 the following characters: 



Scutellum saddle-shaped, emarginate above Eccoptosarge Kriechbaumer. 



Scutellum convexly rounded, not emarginate Matsvmuraius, new genu.s. 



In the shape of the head, the venation, more or less, the scutellum, 

 and the abdomen, this genus closel}^ resembles Automahis Wesmael, 

 but the metathorax is abruptly truncate posteriori}^ the upper hind 

 margin bounded by a carina, the angles toothed, the lateral and 

 pleural carinas distinct, while the spiracles are large and linear; the 

 areolet of the front wings is large, pentagonal, the discoidal nervure 

 and the second recurrent nervure being broken by a stump of a vein.
