(Females)

1. Mesoscutum (Figs 1349, 1352, 1358, 1359) with cellular sculpture that is sometimes slightly obliquely elongate, but not deeper than sculpture on at least basal half of scutellum and usually conspicuously shallower; clava 3-segmented (Figs 1346, 1350, 1356, 1361) ................................................................................................ 2

- Mesoscutum (Figs 1370, 1374, 1379, 1388) with longitudinally elongate striate-reticulate to coarsely striate sculpture that is conspicuously deeper than sculpture on scutellum; clava 2-segmented (Figs 1366, 1372, 1380, 1386) ....................... 4

2 (1) Scutellum (Fig. 1349) completely smooth in apical one-third or so; head very slightly higher than broad in facial view; antenna (Fig. 1346) with F1 subequal in size to F3; linear sensilla on all funicle segments ................... hermippe sp.nov. (p. 537)

3 (2) Dorsum of thorax completely brown (Fig. 1352); antenna (Fig. 1350) with F6 orange, concolourous with rest of funicle and paler than brown clava; F1 and F2 subequal and clearly smaller than F3, F2 without linear sensilla .... isonus sp.nov. (p. 538)

- Dorsum of thorax at least partially orange (Figs 1358, 1359); antenna (Figs 1356, 1360) with F6 brown, concolourous with clava and darker than rest of funicle, or at least proximal funicle segments; F1 clearly smaller than F2, F2 usually with linear sensilla ............................................................................ nigriceps Noyes (p. 540)

4 (1) Hind coxa dark brown .................................................................................................... 5

- Hind coxa white .............................................................................................................. 6

5 (4) Fore coxa dark brown; funicle with linear sensilla present on all segments, funicle (Fig. 1366) with F1 slightly smaller than F2, but F2 equal to F3; propodeum with a group of dense, conspicuous, silvery setae outside spiracle ................................... .......................................................................................... elathes sp.nov. (p. 541)
