as Its basal width, bearing 4-6 hairs. Hind tarsal joint II about 0.100-0.110 mm long. First tarsal chaetotaxy: 3, 3, 2. (Measurements see in Table 2.) DARWISH (1982 and 1983) Illustrated some remarkable variation in the morphological characters of four Brachycaudus species, in both life and mounted specimens. In this respect, In the first instar larva of B. cardui (L.) the number of antennái joints was 4 versus 5 in B. schwartzi CB., B. amygdalinus (Schout.) and B. hellcheysi (Kalt.). In apterous viviparous females of B.car dui and B. amygdalinus antennái joint III was with 0-4 and 0-13 secondary rhinaria, respectively, versus without any in the other two species. Also the first tarsal chaetotaxy in B. cardui was 2, 2, 2 in all stages contrary to that of B. amygdalinus , where it was 3, 3, 2 In all stages, and 3, 3, 2 for B. helichrysi , except the first instar larva which was 2, 2, 2 or 2, 2, 1 when in B. schwartzi it was 3, 3, 3 in all stages except the first instar larva where it was 2, 2, 2.
