Bulletin of the British Museum (Natural History) Entomology. 403. 404 Figs 402—404 Mallada prasina. 402, fore wing; 403, S gonapsis, ventral; 404, apex of 6 abdomen, lateral. origin, and comprises adamsi, basalis, boninensis, desjardinsi, dierli, dispar, flaveola, flavostigma, khandalensis, morota, nea, noumeana, scolius, serrandi, signata and tripunctata. In these species the basal inner gradate crossvein meets Psm, c2 is relatively long and broad and the radial crossveins in the apical half of the fore wing are usually sinuous or oblique. In males, the apex of the abdomen is gaping; the ectoprocts are compressed caudally and sternite 8+9 is elongate; there is a lateral lobe on sternite 8+9; the gonapsis is scale- like; there are few gonosetae which often have an elongate, swollen base; in most species veins Sc and R in the hind wing are closely apposed or fused and the stigma is thickened. Biology. The biologies and larvae have been described in several species including M. boninen- sis (Okamoto) (Tsukaguchi, 1977; Brettell, 1979; New, 1984), M. burgeonina (Navas) (Tjeder, 1966); M. clathrata (Schneider) (Principi, 1956), M. flavifrons (Brauer) (Lacroix, 1925; Killington, 1937; Principi, 1956; Gepp, 1983), M. innotata (Walker) ((Boros, 1984); M. inornata (Navas) (Lacroix, 1925; Gepp, 1983), M. prasina (Burmeister) (Withycombe, 1923; Principi, 1956; Gepp, 1983), M. ventralis (Curtis) (Withycombe, 1923; Gepp, 1983), M. basalis (Walker) (Adams, 1959), M. cockerelli (McCloud) (Smith, 1926b), M. madestes (Banks) (Mehra, 1966; Dessart, 1973), M. microphya (= basalis) (McLachlan) (Terry, 1908; Zimmerman, 1957), M. signata (Schneider) (Boros, 1984); M. traviata (Banks) (Boros, 1984); M. tripunctata (McLachlan) (Boros, 1984). In most chrysopid species occurring in temper- ate regions it is the pupal stage which overwinters; however, in Mallada it is the third instar larva which goes through the winter (Semeria, 1977; Barnard, Brooks & Stork, 1986).
