*33 ( I 3 I ) First funicular segment of antennae as long as or longer than the pedicellus 134 



- First funicular segment of antennae shorter than the pedicellus . . .143 

 *34 (*33) Pronotal collar evenly and sharply, though sometimes finely, margined 



throughout, or except sometimes just at the sides . . . 135 



- Pronotal collar less distinctly and more irregularly margined, the carina only 



at all sharp over the middle third or less . . . . . .136 



*35 ( z 34) Gaster at most slightly longer than broad, barely as long as the thorax ; 

 marginal vein of fore wing at most 1-5 times as long as the stigmal vein, 

 basal cell pilose at least distally ; funicle with all segments except some- 

 times the sixth longer than broad, with (except in dwarfs) very numerous 

 sensilla arranged in two to three rows on each segment. Pronotal collar 

 very short medially (Text-figs. 351-354) . CAPELLIA Delucchi (p. 475) 



- Either the gaster is longer, 1-7 to 4 times as long as broad and at least 



slightly longer than the thorax ; or the marginal vein is nearly to quite twice 

 as long as the stigmal vein ; or the basal cell is bare and at least segments 

 five and six of the funicle are quadrate to transverse. Pronotal collar often 

 relatively long medially . . . . . . . . .136 



x 36 ( J 35) Propodeum with complete plicae, and with the panels of the median area very 

 shiny, smooth or having only traces of weak sculpture ; basal tergite of 

 gaster with a large patch of about 20 hairs on each side ; pronotal collar 

 finely though sharply margined throughout ; spiracular sulci of propodeum 

 distinctly impressed .... TRICHOMALUS Thomson (p. 707) 



- If the median area of the propodeum is shiny and very weakly sculptured or 



smooth, then the plicae are at most indicated posteriorly, the basal tergite 

 of the gaster has fewer hairs at the sides, and the spiracular sulci of the 

 propodeum are very shallow . . . . . . . .137 



*37 ( J 36) Propodeum (Text-fig. 492) shiny and weakly reticulate to virtually smooth, 

 medially usually less than half as long as the scutellum ; plicae absent or 

 indicated only posteriorly. Postspiracular sclerite broad, its upper 

 margin rather longer than the tegula, almost uniformly reticulate 



CHLOROCYTUS Graham (p. 611) 



- Median area of propodeum quite strongly reticulate, sometimes also with 



some coarser wrinkles or rugosity, often more than half as long as the 

 scutellum ; plicae variable, sometimes nearly absent but often nearly or 

 quite complete. Postspiracular sclerite sometimes narrower . . .138 

 z 38 (137) Propodeum (Text-fig. 356) with petiolar foramen deeply, semicircularly 

 excised, bordered by a strongly-raised, crescentic carina which represents 

 the nuchal strip. Gaster ovate, about as long as thorax. Head in dorsal 

 view not notably transverse, about twice as broad as long ; POL equal to 

 or slightly less than OOL. Plicae of propodeum sometimes traceable to 

 base, but often weak or absent anteriorly ; spiracular sulci relatively 

 shallow, smooth or nearly so. Antennal clava in profile appearing sym- 

 metrical MOKRZECKIA Mokrzecki (p. 478) 



- Petiolar foramen of propodeum rarely so deeply excised, or bordered by a 



strongly raised carina ; if so (some Aggelma) then either the gaster is 

 lanceolate and longer than head plus thorax, or else the head in dorsal 

 view (Text-fig. 428) is notably transverse. POL at least slightly greater 

 than OOL. Plicae of propodeum sometimes sharp throughout ; spiracular 

 sulci sometimes deeper and punctate or transversely costulate. Antennal 

 clava in profile sometimes appearing asymmetrical . . . 139 



J 39 ( J 38) Plicae complete, extending to base of propodeum, quite distinct throughout 



although not always very sharp . . . . . . . .140
