FfGURE 196. — Scenopinula pa'.lidipennis Panimonov, female: a, wing; h, lateral aspect of 

 head; c, d, enlarged lateral and frontal aspects of head; e, ventral aspect of 8th sternum; 

 /, lateral aspect of 8th and 9th segments. 



trichia complex and at present may be composed of as many as three 

 genera. Until more specimens are available for study the exact combi- 

 nations are uncertain. On the basis of wing venation, the condition 

 of the short M 1+2 would place bicornis and complexa together while 

 the genitalia of tlie male would place complexa with qiLodrijida which 

 has a closed petiolate cell. The female sternum of bicornis is quite 

 different from that of quadrifida and dycei which have short blunt 

 sterna, but agrees with longiventris which also has a closed cell. The 

 members of this genus are found in the Australian region.
