TRYPHONINiE. 



Tryphonini. 



Cyphanza, gen. nov. 



Transverse median nervnre in hind wings straight, unbroken, areolet oblique, 

 irregular, petiolated, receiving the recurrent nervure near the apex. Disco- 

 cubital nervure rounded, unbroken, not angled. Transverse median nervure 

 in hind wings received shortly, but distinctly beyond the transverse basal 

 Clypens not separated from the face, its sides above with a distinct fovea. 

 Eyes parallel, not incised ; there is a distinct malar space, ocelli in a curve. 

 Scutellum prominent, its sides not keeled. Metanotum with an elongated 

 central basal area, about 6 times longer than wide, extending from the base to 

 the apex, where it becomes narrowed to a sharp point ; there is a square, deep 

 area on either side of the apex ; outerside there is a larger square area, not 

 clearly defined above, the sides outside the spiracles are bounded by a keel, 

 these 2 keels forming the outer boundaries of the outer apical area. Abdominal 

 petiole longish ; its base half the width of the apex ; the sides at the base, are 

 keeled to the spiracles, which are placed at the apex of the basal third of the 

 segment. Antennae moderately stout, longer than the body ; the 3rd joint is 

 distinctly longer than the 4th calcaria short, as long as the 2nd tarsal joint ; the 

 hinder metatarsus is as long as the following .3 united. 



The radius is short, reaching half way between the apex of the stigma and 

 of the wing ; it issues from shortly behind the middle of stigma. In the 

 hind wings of the longitudinal nervures only the base of the radius is 

 indicated. The temples and malar space are of moderate length. The 

 metapleura separated from the sternum by a distinct keel. Mandibles broad, 

 shortly, bluntly bidentate. There are small round spiracles near the base of 

 the 2nd abdominal segment. Body and legs densely covered with short white 

 pubescence. 



In Ashmead's arrangement (Bull U. S. Nat. Mus. xxiii, 70) this genus runs 

 near to Gensia, Foer. 



Cyphanza nigra, sp, nov. 



Black, densely covered with short, white pubescence, the face yellow, except 

 for a black line on the upper two-thirds, the palpi testaceous ; the 4 anterior 

 tibial and tarsi testaceous. Wings clear hyaline, the nervures and stigma 

 testaceous. 



Length 7 mm. 



August. 



Head and thorax closely punctured, the pleurae more closely and strongly 

 than the mesonotum. 



Apex of elypeus broadly rounded, mesonotum and scutellum shining, the 



latter with a curved furrow at the base, centre of metanotum weakly, the 



sides more distinctly punctured. Pleurse weakly punctured. The recurrent 



nervure is interstitial with the 2nd transverse cubital. The antennae moderately
