1973 (1 ex). Rufllus triangulus var. croceus var. n. This variety differs from the type form by having the elytra dull yellow, the antennae appear to be shorter. Both specimens are female. Holotype 5 , Madang, 30. xi. 1969; paratype same data. Dibelonetes nigra sp. n. Similar to D

. hornabrookl sp. n., but differs in being smaller and more slender, the reticulation of the head and pronotum are more elongate and particularly on the pronotum forming rugae, the elytra are a little more densely punctured and also the abdomen. - Black, antennae, maxillary palpi and legs pale yellow. Head a little broader than long, strongly elongate-reticulate, eyes rather strongly convex, their longitudinal diameter half the length of the temples which narrow rather sharply to the "neck", antennae with all segments longer than broad, the second about equal to the penulitmate, last segment longer than the penultimate. Pronotum longer than broad, reticulation forming rugae in which are minute granules; broadest at anterior third and from there broadly concave to the anterior margin. Elytra a little longer than broad, moderately densely punctured, parallel-sides, shining. Scutellum punctured. Abdomen moderately densely and strongly punctured, shining, without microsculpture, with scanty pubescence. - Length 4 mm. Holotype $, Okapa, Ii

. Dibelonetes hornabrooki sp. n. This species is smaller than D. bipunctatus sp.n. and D. striglceps Fauv., in all details. The head is more orbicular, the antenna! segments are much shorter, the two central teeth of the labrum are longer, the rugae of the head and pronotum are less elongate. - Black, except mouthparts antennae and legs which are dusky-yellow. Head slightly broader than long (3.5-3.25) orbicular, eyes convex, their longitudinal diameter a little shorter than temples which are evenly rounded, covered with a network of rugae, in the interstices of which are a number of minute punctures. Antennae with all segments elongate, but from the third each a little shorter than the previous, the second segment equal in length to the tenth, last segment longer than the penultimate, each with a few fine setae at the apex. Pronotum longer than broad (2.5:2.0), narrower than head and elytra, with a network of rugae as on the head with minute punctures, broadest near the middle, posterior margin broader than anterior margin at "neck", with rather long lateral setae, three pairs being in the anterior third. Elytra longer than broad (4:3), parallel-sided, shining, strongly punctured, with one or two weak lateral setae. Abdomen shining, as strongly but more sparingly punctured than the elytra, a single rather long seta from each paraterglte. Aedeagus fig. 17. Legs finely pubescent, inner face of anterior tibiae with an indentation from which there are usually two short black bristles. - Length 5-6 mm.

This species is similar in all respects to D.striglceps Fauv., except that the elytra are reddish-yellow with a small circular black spot, in strigiceps they are black with a little more than the posterior third reddish-yellow. - Antennae, mouthparts, legs pale dusky yellow, elytra reddish-yellow with a small circular black spot, otherwise shining black. Head as long as broad, covered with a network of longitudinal rugae, the Interstices having minute punctures; eyes large convex, their longitudinal diameter two thirds the length of the temples, where there are a few weak setae. Labrum with two small central teeth; segment of the antennae very elongate, the
