A single example. The disk of the elytra is wholly black. 23. ASPIDOMORPHA ARUWIMIENSIS, n. sp. Ovata, nigra; prothorace elytrisque pallide testaceis, his irregulariter (dorso subseriatim) punctatis; illo basi quam elytra angustiore, maculis duabus rotundis nigris, margine antico subreflexo. Long. 12, lat. 9 millim. The body, head, legs, and antennae of this species are wholly black, the latter about as long as to reach to the hind angles of the thorax, their third joint half as long again as the fourth. The thorax has the extreme edge of the margin blackish ; there are a few obsolete punctures on each black spot and on the lobe just before the scutellum. The scutellum is black, but has a yellow mark at its apex, it is indistinctly impressed. The humerus is prominent; the elytra are destitute of marks above or beneath, the extreme edge is very faintly brownish ; the punctuation is distinct but irregular, here and there, as near the suture and in one row starting from the callus, forming series. Two specimens of this insect were obtained by Mr. Bonny in the Aruwimi Valley. It has not very much the appearance of an Aspidomorpha ; the claws are, however, pectinate at their base ; and in general structure it seems to m e to agree better with that genus than with any other known to me. 24. LACCOPTERA INTRICATA, Klug. Laccoptera intricata, Klug, Bohem. Mouogr. iii. p. 59. One example. This species is extremely common at Old Calabar and at other places in Guinea. 25. CASSIDA SIGNATIPENNIS, Bohem. Cassida signatipennis, Bohem. Monogr. ii. p. 345. One specimen. This species is also common at Sierra Leone and in Senegal. 26. CASSIDA BONNYANA, n, sp. Cassidae hepaticae statura et summa similitudine; nigra, prothorace elytrisque brunneis, his vix nitidis, creberrime minute punctatis, illo punctis duobus discoidalibus nigris, margine antico elevato. Long. 13, lat. 9 millim. The inner side of the first four joints of the antennae, the epistoma, and a dot on the crown of the head are rufous ; the thorax and elytra reddish brown, on each side of the middle of the disk of the former is a black dot of medium size, and this together with the rather dull surface will at once distinguish this species from C. hepatica |
