Show 1883.] MR. W. L. DISTANT ON THE CICADIDAE. 191 long slender spines on each side. Opercula small and oblique, not passing the base of abdomen. Long. 21 millim. ; exp. tegm. 62 millim. Hab. New Caledonia (Layard). (Coll. Dist.) Other specimens from the same locality in the collection of Dr. Signoret, which I have since examined, are somewhat darker in hue, especially the anterior legs, which are brownish. Montrouzier's description is so slight that I certainly should have failed to identify his species had I not received specimens so labelled from Dr. Signoret. I have therefore given a full description of this insect, which I have placed provisionally in the genus Tibicen. From this, however, it somewhat differs in the ulnar veins at base, which, though distinctly separated, are yet contiguous, thus approaching the genus Melampsalta. MELAMPSALTA OLDFIELDI, n. sp. 2 • Head, pronotum, and mesonotum greenish ; abdomen greenish ochraceous, a central longitudinal castaneous fascia extending from base of head to apex of abdomen. Head with four large black spots on vertex, two at area of ocelli, and two in front of eyes ; mesonotum with pale ochraceous margins to the central castaneous fascia ; central base of abdominal margins blackish. Body beneath pale greenish ochraceous ; face castaneous with its whole central disk black. Tegmina and wings pale hyaline ; tegmina with the costal membrane and basal venation greenish, remaining venation pale fuscous; claval area and that between the postcostal vein and the postcostal ulnar ramus warm ochraceous. Wings with the base ochraceous, the claval area more or less suffused with the same colour, the veins greenish, becoming fuscous towards outer margin. The anal sheaths enclosing ovipositor are fuscous, and project considerably beyond the apex of the abdomen ; the ovipositor is dark castaneous, the last abdominal segment being triangularly excavated at its emergence; the rostrum just passes the intermediate coxae, and has its apex castaneous ; the face is laterally compressed and concave on each side, the central sulcation being very deep. Long. 21 millim.; exp. tegm. 55 millim. Hab. New Holland, sic. (Coll. Signoret.) The broad central castaneous fascia on the upperside of the body of this species renders it very distinct from the other numerous Australian species of the genus. CARINETA CROCEA, n. sp. (Plate XXV. figs. 1, la, 16.) 8. Body and legs dull ochraceous and sparingly pilose. Head above strongly hirsute, with the area of the ocelli infuscated. Pronotum with a short basal longitudinal castaneous spot. Mesonotum with two obconical black-margined spots at anterior margin, on basal sides of which are two small black marginal spots, a castaneous transverse spot in front of the cruciform elevation, on each side of which is a subquadrate black spot. Beneath, the abdomen is rather |
