BREYERIA; CRAMBOMETRA; CAMPYLOCTIS; DIASTEMINA. By M. Gaede. 431 
62. Genus: BSroyei'ia Janse. 
Palpi short, proboscis absent. Antennae with long pectinations as far as the tips. On the thorax and 
at the base of the abdomen a hair-tuft. Costal margin of fore wing almost straight. Veins 3 and 4 distantly 
separated, 6 -)- 7 + 8 + 9 stalked, 10 forming the accessory cell with the stalk of 7 -f- 8 -f- 9. Hindwing 
somewhat triangular, vein 5 feebler, 6 + 7 on a long stalk, 8 close to the cell as far as its end. Accordingly, 
the genus fits theoretically less to the preceding ones, but the external resemblance is great. 
B. dasychiroides Janse (71 d). Thorax and forewing dark greyish-brown with black lines, reniform dasychiroi- 
macula indicated white, fringes speckled. Abdomen light greyish-brown, hindwing white. 29 mm. Transvaal. 
The two following genera almost look like Geo m e t r i d a e. They have large, 
strongly pectinated antennae, and a slim body. In the hind wing veins 6 and 7 rise 
separately. 
63. Genus : Crambometra Prout. 
Proboscis well developed, palpi long, erect. The long antennae strongly pectinated. Forewing narrow, 
vein 6 below the upper cell-angle, 7+8+9 stalked, 10 forming the accessory cell by a bar with the stalk of 
8 + 9. Hindwing large. Vein 5 feebler, 8 close to the cell as far as its centre. 
C. derelicta Prout (71 e). Body and forewing pale ochreous, finely dusted with blackish-brown. A derelictci. 
short blackish-brown radial streak below the cell, and an exterior line which is strongly notched in the cell. 
Hindwing yellowish-white. 36 mm. Natal. 
64. Genus: Campyloetis Janse. 
Palpi porrect, proboscis well developed, antennae large and broad. Forewing broader than in Crambo- 
metra. Vein 6 below the upper cell-angle, 7 + 8 and 9 + 10 on long stalks. Hindwing as in Crambometra. 
€. gladstonei Janse (71 e). Thorax and forewing ochreous. Interior and exterior lines blackish-brown, giadstonei. 
strongly undulated, indistinct. Submarginal line notched, more distinct. In the centre of the cell and in the 
submedian fold a dark radial shadow. Abdomen and hindwing yellowish-white. 40 mm. Transvaal. 
VIII. Antheua-Group. 
Strongly built forms, mostly of yellow ground-colour. The neuration is often rather variable within a species, so that 
the generic differences are not easiliy stated- Consequently species evidently belonging together are placed to different genera 
by various authors. 
65. Genus: IMastemilia nom. nov. (Diastema Aur.) 
Proboscis present, palpi short, erect. Antennae of <$ strongly pectinated, in the $ shorter, at the tips 
dentate. In the fore wing veins 3 and 4 separated, 6 from the centre of the accessory cell, 7 and 8 + 9 from its 
apex, 10 from its anterior edge. In the hindwing veins 3 and 4 separated, 6+7 stalked, 8 close to the cell. 
Type : simplex W kr. 
D. spurcata Wkr. (71 e). Head and thorax orange-brown, patagia and metathorax pale yellow. Forewing spur cat a. 
pale yellow. On the median vein and below vein 4 a strong olive brown radial band almost to the distal margin. 
Hindwing white. Abdomen above black or olive brown, at the end pale yellow. 45—50 mm. Togo, Congo, 
Central Africa. 
D. simplex Wlcr. (71 e) is a very vaviable species. The nomenclatural form simplex (= straminea H.- simplex. 
Schajj.) has an orange thorax, pale yellow forewings with brownish patches between the veins. Hindwing 
white. — cinerea Wkr. is a somewhat darker form with an olive brown abdomen. — sericea Fldr. has on orange- cinerea. 
brown thorax and black abdomen. Forewing dark olive-brown, only at the costal margin and in the submarginal sericea. 
fold pale yellow, as well as single veins more or less light. Particularly dark specimens are: olivaceomicans olivaceo- 
Strd. (71 e). 50—55 mm. Everywhere in West, East, and South Africa. micam 
D. ornata sp. n. (71 e). Head, thorax and forewing orange, abdomen above and laterally black with ornata. 
brown lateral dots, beneath yellowish-white. Forewing with distinct black bands in the cell, the submedian 
fold, and below it, as well as between veins 2 and 7, except above vein 4. Hindwing white, in the $ slightly 
yellowish. 48 mm. Abyssinia. Type in the Berlin Museum. It may be an extreme form of the following species. 
D. trivitta Pimps. Thorax and forewing pale ochreous. Short black streaks from the base at the median trivitta. 
vein, above the inner margin and above vein 3. Hindwing (d) white, at the anal margin somewhat yellow. 
50 mm. Abyssinia. 
D. radiata Aur. Forewing whitish. All the veins dusted with greyish-black, particularly above the radiata. 
base of veins 2 and 3. Hindwing straw-coloured at the base and anal margin. Both wings with a black marginal 
line. 45 mm. Transvaal.
