The figure was made before I knew that the

g~nus

had alread'y been published by Dr. Gerstaecker. The speCles, hm\,ovo1',

IS

quite new, and is a vel'yintel'esting addition to the genus, as well as to the fauna of the vVhite Nile. The al;rllcture of the rostrum is peculiar; there is a delicate ridge a~ong the 10",:e1' margin, and above is the outer of the three dorsal l'ldgos 01' carlllulro; betweoll the two is a flat surface which, for Dr. GOl'staeckor, is the scrobo.

This,

in

the species before us, would

make

part of the sC1'obo to extend above the eye, a peculiarity,

I

think, without examplo. CU

is well represented in fig. 5 a, PI. VI.) The 1'oal scrobes are, I believe, the short, deep, well-defined fovere at the tip of tho ros- trmn. M. Lacol'daire (Gell, vi. p. 57) takes this view, although

in a

note he puts it the other way "a volonte," at the same time crediting M. Gel'staecker withjust the opposite view to that which he holds as I have hel'e stated. See Berliner Monatsbe- richt, 1855, p. 84, and Reise nach Mossambique, Ins. p.311, 1862.

The FaakY1'ltync7ti here described are mostly due to the re- searches of Dr. Semper in the Philippine Islands, and comprise some of the most beautiful and isolated of the genus. Three species only were found by Mr. Wallace in the Malayan archipe- lago, two of which, derived from Dntch collectors, are described by Van Vollenhoven; the other, P.

aingulat~l8,

is new. The spe- cies vary considerably in colour and the number of spots; the latter are almost entirely formed by scales more or less densely seated in depressions of the derm; sometimes, in some individuals, a few scales may b0 found scattered on the head and prothorax which are absent in others.

P. nigel'; nitidissimus; pl'othol'UX maculis quinque, elytra maeulis numel'osis majoribus (circa 20), quurum duabus eommunibus sutUl'a pone medium sitis, e squamis crel'uleatis roseo-marginatis effectis; capite pedibusqlle omnino glabris, rostro apicem versus subtiBter punctulato leviter transvcrsim sulcato, in medio late lU'ofuncle excavato; pl',?thorace oblongo, antice fortitel' 1'0-

at the apex have two rows of stout black setre.

In Episomu8 the scrobes are confined, so to say, to nearly the point of origin of the antennre, or are marked bebind by a gene- rally broad sballow impression, which entirely disappears in front and before attaining the eye, and is invariably closely covered by sca1es of the same character as the rest of the rostrum. The de- scription of this part is not very satisfactOl'y either in Schonherl' or Lacordaire. The scape in Episomz68 impinges more or less on the prothorax; but here it passes only just within the anterior border of the eye.

is with some hesitation that I place this genus with Mo]y- tinre, the subbasal scrobes being at variance with the

of'the subfamily; it may be only a sexual peculiarity. The ciliate tarsi are found in

the partially ridged margin of the side of the prothorax occurs also in some Anclwni.

The only character by which this genus differs from Gonipte- rinre as defined by Lacordaire is the narrow intercoxal process.

As to the spurs of the tibire, they are well marked in some

Goni-

pte1i, e. g. G. lepidotus, though there is but one to each. The so- litary specimen on which this genus is founded is the sole repre- sentative of the subfamily, of which more than fifty species are fonud in Australia, contained in Mr. -VVallace's Malayan collections.

There is no other genus with bifid claws among the Hylobiinre ; and

in

There are three well-marked species, of which two are described below; all my specimens appear to have been covered with a dull greyish crust or squamosity, in addition to ordinary scales, that seems to be easily detached, except in the punctm'es.

The type of this genus is very like some of the smaller Austra- lian Orfhorini, to which, in fact, it is closely

al~ied,

differing principally in the character of the tibim and of the posterior fe- mora; the latter m'e very remarkable, and can only be paralleled among the Tachygoninre, a subfamily of the Aulacostethous

The diagnoses of this and the following species are drn.Wll up

to contrast with the two described by LacOl'daire. In this spe-

cjes, which approximates to D. lwiZopoitlos, the elytra arc gradually

narrowed to the apex, which is deeply and angn1'trly emal'giuate,

with the outer angle on each side rather produced; the

This species differs from D.

intm'

alia,

in being much stouter in all its parts; in the third joint of the antennre being nearly as long as 1.he two next together, and in the four ter- minal joints being shorter and broader; the apex of' each elytron is obliquely ernarginate 'within; in D.

itltyceroidcs

there is only a single fascicle at the base on each side, and there is no ochl'a- ceous powdery substance on the elytra, the tibire are much thickened at the apex, and in both species the middle of the tibire is covered with white hairs.
