ONCOPERA; TRICTENA. By R. Pfitzner f and M. Gaede. 
jordani. Ch. jordatii Pf. (73 b). With this species which is unlike any other Charagia and which I have deno¬ 
minated in honour of Dr. Jordan (Tring) I conclude the seiies. I received only a single $ from West- 
Australia (Mornington) and have placed it to the Charagia for the present. I simply repeat here my de¬ 
scription in Iris XXII, p. 138: Size 96 mm. Apex damaged on both sides. Nevertheless it is easily noti¬ 
ceable that the forewing had originally the well-known falciform apex of the Charagia-<$<$. Considering this, 
the real expanse must have been 100—110 mm. Length of the body: 45 mm, projecting but little beyond 
the anal angle. Thorax white above, with dull bluish-green hair beneath. Abdomen brownish-yellow, legs 
above bluish-green, beneath yellowish-brown. Hair-pencil on both sides cinnamon-brown. Head brownish-white, 
antenna filiform, 3 mm long, brownish. Wings broad, distal margin of forewing uniformly rounded. Relatively 
densely scaled. Upper surface: colour (excepting the rubbed-off places) uniformly chalky white. Erom the 
centre of the inner margin of the margin a yellowish olive brown line, about one millimeter broad, slightly 
curved in its upper part, extends into the costal margin, ending 10—15 mm before the apex; another similar 
one, though indistinct, is parallel to the distal margin. It is apparently uniformly bent and, provided its com¬ 
pleteness, it would unite with the line mentioned first, forming the figure of an arc, the first line representing 
the chord. Beneath as above, but the veins more or less intensely bordered with brownish olive, especially at 
the costal margin of the fore wing, which is broadly covered with brownish hair. The dark transverse lines 
are distinctly noticeable. The hairs of the bases of the wings exhibit a faint bluish-green tint. The $ of 
this peculiar, quite isolated species is still entirely unknown. It presumably numbers among the largest 
forms of Charagia. Type in the Coll. Pfitzner in the Senckenberg Museum (Frankfort-on-the-Main). 
3. Genus: Oneopera Wkr. (Oncoptera Meyr.) 
Antennae short, only in the typical species ( intricata) club-shaped at the end, almost wire-shaped, with 
a hair-tuft at the base, hanging over the eyes. Palpi moderately large, straight, scantily covered with long 
rough hair. Hind tibiae (of intricata) with a broad long hair-tuft parallel to the abdomen. In the other species, 
the hair-tuft does not extend beyond the tarsi. 
cpargyra. 0. epargyra Trnr. Body blackish-brown, greyish-white at the end. The broad forewing is dark brown, 
brown at the base and costal margin. 4 or 5 dark brown spots at the end of the costal margin. A variably 
large silvery white discal spot at % of the length of the wing, connected with a silvery white oblique streak 
which extends to the inner margin near the anal angle. Sometimes, however, this oblique streak is absent. 
Hindwing with a round apex, blackish-brown, whitish-grey at the apex with 4 dark spots in it. 36—40 mm. 
Queensland. 
brachyphyl- 0. brachyphylla Trnr. Thorax brown, abdomen dark brown. Forewing broad also in this species, but 
?a - the apex not so pointed as in epargyra. Forewing brown, sometimes dusted dark brown; costal-marginal area 
paler, with dark striae. A variable spot, connected with a line, as in epargyra. Besides there is sometimes a 
short faded white stripe extending from the base along below the centre. Hindwing blackish-brown. 35 
to 40 mm. North Queensland. 
intricata. 0. intricata Wkr. (75 d). <d 31—41 mm, $ 48 mm. Brownish ochreous, forewing with a whitish mark¬ 
ing. The habitus is somewhat similar to that of our H. fusconebidosa (velleda ), but the wings are narrower 
and more pointed. Very variable. Victoria, Tasmania, from October to December, common. 
mitocera. 0. mitocera Trnr. $ 32—46 mm, $ 48—59 mm. Head and thorax reddish-brown, greyish-brown in 
the $. Palpi dark brown, antennae filiform, slightly thickened at the end, dark brownish. Abdomen dark. 
Legs black. Forewing elongate and narrowly reddish-brown, darker in the $, marbled dull brown; 
sometimes with scattered whitish spots. Fringe reddish-brown with black rings. Hindwing dark with a whit- 
ish-ochreous blotch at the apex. Margin dark brown with some whitish-ochreous scales. — An aberration 
with a whitish line from the base to the interior angle where it meets a white transverse stripe may be 
turneri. denominated: ab. turner!. Queensland (Kuranda, Atherton, Herbert on). — Some aberrations of this species 
suffusa. have been denominated: ab suffusa Aur. Forewing brownish ochreous with 3 irregular dark brown bands 
hardly reaching the costal margin, but connected at the inner margin. The two first of them are broad, the 
third submarginal band is excurvecl in the middle, all of them are strewn with small white dots. — ab. 
lineata. lineata Aur. is rather uniformly spotted brownish-ochreous and dark brown on the forewing. A white undu- 
vittata. late postmedian line, edged with dark, extends from vein 7 to the inner margin. — ab. vittata Aur. is brown¬ 
ish-ochreous on the forewing. A median band extends almost from the base to the cell-end, from where 
it is expanded into a large spot towards the apex and the anal angle. All the forms from Queensland. 
4. Genus: Trictena Meyr. 
Body and antennae similar as in the Lasiocampidae, but the antennae have 3 rows of pectinations, and 
a row of shorter dents is yet between the two main rows. Palpi very long, straightly porrect, somewhat knobbed
