over the basal 2 is of the length of the pala ; the apical row forms an arch, very strongly curved at the base, then running along the curvature of the outer palar margin. On the single pala, which I have been able to examine, the number of teeth was 20 in the basal row and 19 in the apical one. Fore legs of the 9$ do not show anything remarcable. Unfortunately I had no sufficient material to measure the relative length of the various parts of the intermediate and hind legs. Strigil rather large, elongated, with about 7 partly abbreviated combs (%. 7). Right forceps (fig. 8) wide and hyperbolically prominent on the first curvature, terminated by a long hook-like processus. Left forceps rather wide (fig. 9), bluntly rounded at the end, with numerous short spines, scattered over its outer part, inner sheath of the penis with two terminal appendices. Length 7 mm. The examined specimens were from Baku, Transcaucasia. This species seems to be very closely allied with the following one. Sigara (s. str.) Fussi (FIEB.), 1864. Corisa Fussi FIEBER, Wien. Ent. Mon. VIII, 1864, p. 208. Elongated elliptical, nearly parallel-sided, the 99 somewhat wider about the middle of the hemelytra than the cfcfGround-colour of the pronotal disk and of the hemelytra brown ; head, underside and legs yellow; base of the abdomen from beneath, especially so in the o"cT, and ends of intermediate tarsi darkened. Frontal arch distinctly more prominent in the <f cf than in the 99Head, seen from above, equal in length in the çfçf to about Vs of the length of the pronotal disk, in the 99 the head is almost twice shorter than the pronotal disk. Facial impression of the cfcf very distinct and large, resembling much in shape that of the preceding species. Face nearly glabrous in both sexes. Fourth antennái joint equals in length 48*3 ( 7 0 of the length of the third. Length of the pronotal disk equaling about 2 /a of its breadth. Lateral angles rounded in front, forming a right angle posteriorly. On the pronotal disk about 9 pale transverse lines, partly furcated and confluent. Lateral lobes of the prothorax tongue-shaped, rounded at the apex. Pronotal disk and clavi distinctly hut rather feebly rastrated, corium almost without rastration, membrane smooth. The pattern of the hemelytra (fig. 10) resembling in general that of the preceding species, but the
