Description. -Diagnosis as for genus group. Size (in mm): total length, male 20-30, female 28-44. Integument finely rugose. Antenna ensiform, somewhat shorter than combined length of head and pronotum. Head conical, face oblique, straight, or broadly convex; variable even in same locality. Fastigium parabolic with fine medial and lateral carinulae. Frontal ridge sulcate with high carinulae diverging downwards. Dorsum of pronotum flat, wide, with sharp strong carinae; lateral carinae straight, parallel, or slightly divergent backwards; only posterior sulcus crossing dorsum, metazona slightly shorter than prozona, its posterior margin obtuse-angular. Male genital structures as in Fig. 97 ( D. c. phippsi ). Coloration extremely variable in shades of dark to light-brown and stramineous, often with admixture of shades of green and presence of dark lateral fascia. Dorsum predominantly in shades of brown, but occasionally in other colors, including a vivid deep pink pigmentation; sides are frequently green. Discussion. -There is no marked constancy in color patterns; sometimes a local population may exhibit a fairly homogeneous picture, while another elsewhere presents a wide range of variation. This could be a reflection of the ecological conditions of the habitat, but precise observations are lacking. Distribution. -The typical subspecies is by far the most widespread and variable of the three. Occurs in whole Ethiopian region except for deserts; all East African countries including SOMALIA (omitted from COPR (1982) but cited in Johnsen and Schmidt (1982) and Baccetti and Abukar (1987) ); in much of southern Africa replaced by Duronia chloronota curta ( Uvarov 1953 ).
