The third median cell was simple without a looping posterior branch, neither ovate nor quadrangular. In all the jeanneli-group species that we have examined cell im is ovate. Indeed, the form of im in Nesochrysa grandidieri is unique in the Chrysopidae. Therefore, the condition that Navas described for Chrysemosa may be aberrant or restricted to one species (as in Nesochrysa) but in any case it is not of generic significance. It therefore seems to be a reasonable supposition to include the jeanneli group species in Chrysemosa. Biology. Unknown. No insect remains were found in the guts of any of the adults examined during this study. Genus CHRYSOCERCA Weele Chrysocerca Weele, 1909: 75. Type species: Chrysocerca jacobsoni Weele, by original designation and monotypy. [Synonymized with Nineta Navas by Lacroix, 1924: 571; reinstated by Tjeder, 1966: 345] Pseudochrysa Okamoto, 1914: 55. Type species: Pseudochrysa formosana Okamoto, by mono- typy. [Synonymized by Kuwayama, 1966: 137.] Distribution. Uganda, Oriental region. Five species have been described in Chrysocerca and there is a further undescribed species in the BMNH collections. Only one species is known from the Afrotropical region. Diagnosis. Adult. Small to medium lacewings, fore wing (Fig. 287) 9-13 mm; ground colour pale green. Head unmarked or with red or black markings on gena, clypeus, frons and scape; mandibles broad, symmetrical, with basal tooth on both mandibles; galea broad; palps tapered; labrum indented; vertex raised; head width : eye width =
