24r, 
by black spots which almost disappear in front. Beneath the median band is not white, bnt burning yellow, 
and extends somewhat basad at the costal margin. 
C. restricta Hmps. Forewing only dark chocolate brown. The marking not ])nrely white, but nnn-e nsirirh/. 
flesh-coloured. Costal-marginal band not differently shaped. Median band slightly incnirved on its inner side 
behind the cell, also above the anal angle, with a few red scales there. The narrowly white flesh-colonied margin 
is finely brown outside. Hiudwing red, the marginal band broad as far as vein 4, then 3 decieasing black spots. 
Beneath the Avhite median band of the forewing is faded inside. 4()--42 mm. Niger District. 
42. Genus : Aeaiitlioilelta Hmps. 
Somewhat different from the usual neiiration, since vein 3 arises somewhat farther- basad iir brrth wings 
than in the other genera. All the tibiae s])ined. Only 1 species. 
A. distriga Hrnps. is a rather unicoloured greyish brown s])ecies with a cojrirery gloss, of the size of 
C. euclidica, with relatively lai'ge hindwings. Thorax dull reddish brown, wings and abdomen gi-eyish brown. 
Forewing wdth a black dot at the lower cell-angle. A white streak behind the middle of the cell almost t(r the 
margin, a similar one in the submedian fold, enclosing a black dot behind the middle. Hindwing with an un- 
dnlated dark marginal line. ^ 40 mm. Gape Colony. 
43. Genus : Orammocle;^ Gn. 
This genus and the following ones look again like those preceding AftalJia. Nenration normal. ^Middle 
and hind tibiae sjrined. Type: geometrica F. from Europe. About half of the 14 s])ecies known occur iu Afi-ica. 
Some are distributed over the warmer districts of nearly the whole Earth. 
G. congenita Wkr. (29 e). Greyish brown with a violet reflection. Interior band white, somewhat in- cnugotiln. 
ward, straight, beginning below the costal margin. Broadly blackish before it, narrow'ei- blackish towards the 
costal margin. Median area blackish from below the costal margin to the inner margin. Exterior band olive 
brow-n, edged white inside, bent basad at the costal and inner margins. The band is l)ordered outside by black 
spots which project pointedly outward at veins 6 and 4 as well as at the inner margin. A black spot at the apex, 
bordered outside by a distinct oblique line from the apex, faded towards the base. A whitish submarginal 
shadow behind it from the apex to the inner margin. Hindwing dark brown, blackish at the margin, with an 
extinct white band from the middle of the costal margin to the inner margin near the anal angle. 35—40 mm. 
Africa, to the south of the Sahara, presumably everywhere common. 
G. geometrica F. (Vol. Ill, ]d. 01 d) is larger on an average than the preceding s])ecies. The differences f/comdrica. 
are very slight; perhaps they are forms of one species. Median band of hindwing above broader and more con¬ 
spicuous, not so extinct. Forewing beneath with a stronger white exterior band which is more distinctly tra¬ 
versed by the dark veins. There are specimens in which the white median band on the forewing above is very 
narrow and does not extend in front into the cell, or it is normally broad and of a glaring yellow colour. 
35—45 mm. From Southern Europe to Australia, and throughout Africa. It has been dealt with already in 
Vol. Ill, p. 331, where all the details about the larva are also to be found. 
G. exclusiva Pag. (29 e) is placed by Hampson as a form to congenita (29 e). But it does not differ merely c.vdusiva. 
in a narrow interior band. It is considerably smaller, darker, and above all the exterior line is slightly though 
distinctly inserted between veins 2 and 3, Avhereas it is straight in congenita and geoinetrica. The dark apical 
spot is bordered by a white oblique line from the apex in nearly all the s]>eciniens, which line mostly extends 
at vein 6 to the exterior band. All the typical specimens are from Madagascar, but 1 have also a specimen at 
hand from East Africa, which likeAvise shows the bend of the exterior line. Median l)and of hindwing lighter 
than in congenita. 25—30 mm. 
G. stolida F. (Vol. Ill, pi. 61 f) has a range just as large as that cA geometrica. It has been dealt with doUda. 
in Vol. Ill, p. 331. 
G. euclidioides Gn. (— dubitans Wkr.) (29 f). Forewing so very similar to that of exclasiva that we eKctidhndcs. 
may refer to the description of the latter. Only the hindwing and the under surface of both wings are dark 
orange. Hindwing above with a doidile straight didl brown median line. Submarginal band black, mostly 
broad, but sometimes only at the apex so. Margin likewise black, narrowest behind the cell. 25—30 mm. 
Everywhere common in South Africa. 
G. microgonia Hmps. (29 e) is marked like the Chalciope-species (p. 346) and was originally also described min-ogonia. 
as a Chalciope. Thorax and forewing reddish brown with a slight violet reflection. A velvety black triangular 
spot at the base below the cell, extending at vein 1 almost to the centre of the A\'ing. A similar spot behind 
the middle. One side parallel with the costal margin, the other obliquely parallel with the exterior edge of the 
basal spot, the third vertical to the inner margin. A black oblique line from the a])ex to vein 6, then straight 
on, somewhat inw'ard. On the outside of this line irregular short black notches. The broad margin behind it 
more intensely violet. Hindwing greyish brown, the margin broadly blackish brown. 40 mm. Rhodesia.
