STEFANI (1946: 131) accepted this tentative association as definitive, and described his dissimilis as "colore generale de corpo rosso-ferrugineo = dissimilis" and "colore generale del corpo bruno-nero = crassifemorata", characters which for sclerogibbids do not hold at the specific rank. DR. VAN ACHTERBERG (pers. comm.) arrived at similar conclusions dissimilis being the same as crassifemorata, while mancinii is different. 5.

Only in three females from the Tel Aviv area size varies from 3.0 to 5.0 mm. All specimens have, however, tridentate mandibles, but the median tooth in the female is sometimes very small, inconspicuous. Antennae with 24-26-27 segments (sometimes right side differs from the left). In the largest female, front angle of ocellar triangle much greater than right angle, in smallest female a little less than right angle. POL : OOL in these three females vary from 2.4 to 3.0. Males: 264 specimens examined, varying in size from 2.0 to 4.0 mm. Front angle of ocellar triangle quite invariably less than right angle (it is right angle in C. mancinii and much greater than right angle in S. crassifemorata males). The fore-wing may be strongly infuscated or hyaline. It is curious that sometimes the presence of strongly sclerotized, curtailed vein, which starts from the first sector of the radius, merges halfway toward the articulation of submarginalis on basalis. It may be present on one wing alone or on both wings. The most remarkable variation concerns the shape of the head. This may be transversally ovoidal, with frontal lobe not produced and 1.25X as broad as long, the else definitely tringular in shape, with frontal lobe strongly prominent and then only 1.05 X as broad as long. The two extremes appear as two distinct species. However, all intermediate form occur in series collected at the same time and place. Remarks — The lectotype of embiidarum was examined by RICHARDS, who found POL : OOL to be 2.5, and by KROMBEIN, who found the same rapport to be 3.3 in the same specimen. He described taprobanana because it had POL : OOL only 2.6-2.8. Both of the above authors examined females from Israel, which were sent to RICHARDS by
