^ledian segment aveolated, tlie keels not very distinctly 

 defined ; there are two central arejy, the basal reaches to the 

 middle and is contracted roundly and largely near the base. 

 Areolet slightly oblique; the transverse cubital nervures are 

 united above. The second and tiiird abdominal segments are 

 closely punctured and longitudinally striated at the base ; the 

 ventral keel is largely developed on the second and third 

 segments ; the seventh segment is largely developed all 

 round. 



The wings are hyaline ; the head is large and broad and is 

 well developed behind the eyes, which reach near to the base 

 of the clypeus ; they are margined on the inner side ; the face 

 is flat and is not separated from the middle of the clypeus ; 

 the latter is bounded above on the sides by an oblique 

 furrow ; the mandibles have a longish upper and a shorter 

 stout under tooth, which is curved inwardly. Legs stout ; 

 the tarsi spinose ; the fore tibiae are narrowed and slightly 

 incised at the base and thickly spined ; the abdominal segments 

 are not angled at the apex laterally, but broadly rounded. 



The type of the genus is a stoutly built insect, with a large 

 head and stout short antenna?. The legs are also stout and 

 with large hind cox re ; the hinder trochanters reach to the 

 apex of the third segment ; the last segment above is more 

 than one half the length of the penultimate. The dilated 

 antennae in the female (the only sex known) and the absence 

 of reo-ular arege on the median segment would refer it to the 

 Joppina, and. if anywhere, to the Hemijoppinai DoryphoraB 

 of Kriechbaumer. The distinguishing characteristics are the 

 short, stout, dilated antennae, the quite Hat large sculellum, 

 not keeled laterally, and the three central narrow arege, not 

 clearly separated, on the median segment. The median 

 segment is large and has a gradually rounded slope ; the 

 spiracular area is bounded by two keels.
