  Type data:

   
  Syntype(s) BPBM sex, quantity unknown (coll.: iii-iv.1905), Rewa, Fiji; BPBM sex, quantity unknown (coll.: ii.1905), Navua, Fiji; BPBM sex, quantity unknown, Viti Levu, Fiji
  Comment: Kirkaldy (1907) only mentions females in his description so it is likely there are no male syntypes.

Diagnosis

Allied to C[icadula] rufa (Melichar). but the head is longer, pronotum shorter, legs pale. etc. Bright scarlet; vertex pale testaceous with a mediolongitudinal suffused scarlet stripe which forks at the base of the frons and extends all over the face suffusedly (sometimes the red stripe is obsolete at the fork, the frons then being entirely pale, only the genae and the clypeus. etc.. red.) Apical third of tegmina hyaline, iridescent, veins there pale yellowish. Wings hyaline, iridescent, basal veins pale sanguineous. Tergites mostly sanguineous. Underside and legs pale testaceous, the former sometimes a little suffusedly sanguineous. Vertex longitudinally sulculate, anteriorly somewhat swollen, longer than wide, roundly produced before the eyes. Pronotum scarcely wider than the head and only about one-half of its length, shorter than the scutellum, scarcely emarginate posteriorly, lateral margins short. Tegminal venation that of C. rufa, except that the interior branch of the first apical vein is curved. Female: last sternite very slightly sinuate, the pale part longer than wide. Length 2½ mill. (Kirkaldy 1907).
