slightly excurved in centre, undulate. Distally 2 indistinct undulate dark median lines. Reniform stigma small 
with black surround. Postmedian line finely black, angulated outwards below costa and on vein 4, in between 
somewhat inwards, below vein 2 obliquely inwards. Submarginal line indistinct, pale, undulate. Hindwings pale 
ochreous brown; a median and outer line are indicated at inner margin. In $ forewings are more uniformly fus¬ 
cous. 20—25 mm. Algeria, Soudan, East Africa. 
C. balnearia (30 b). A nice large species. Body grey-brown. Forewings darker at base. Antemedian 
line distinct, black, somewhat excurved at submedian fold, otherwise vertical. Median area fulvous with 3 
delicate fuscous lines. Reniform stigma small, quadrangular, with black edge. Outer line black, excurved m 
a small semicircle in centre, impressed behind cell, at vein 2 in a large arc edged by dark shading inwardly and 
narrowly outwards. Marginal area pale grey, enclosing the white dentate submarginal line, that has a darker 
patch distally at apex. Hindwings yellowish, tinged with brown at margin. 26—34 mm. Mashonaland, Trans¬ 
vaal, Tanganyika, East Africa. 
C. polycyma i/mps. (30 h). Thorax and forewings dark reddish brown. Antemedian line black, somewhat 
angulated outwards below costa, then undulate, vertical and somewhat darker proximally. In central area a 
few indistinct dark lines. Reniform stigma narrow with diffuse dark outline and with a line jjroceeding from 
it to inner margin. Outer line distinct and black, angulated inwards behind the cell, above and below in equal 
large arcs outwardly. At vein 2 the large arc extends slightly further inwards than in balnearia. Parallel distally 
a fainter dentate line, the interstice between the two being darker. Submarginal line pale, dentate, somewhat 
darker proximally of it at costa. Hindwings ochreous brown, darker at margin. $ 32— 36 mm. Uganda, Rhod¬ 
esia. Only 2^9 known. 
C. phaeocyma Hmps. (30 h). Body and forewings dark brown. Antemedian line black, rather indistinct, 
bulging forwards in centre. Median line diffuse, double. Reniform stigma whitish, with black edge, elliptical, 
a dark line j^roceeds from it to inner margin. Postmedian line black, distinct, more pronouncedly angulated 
outwards below costa than hitherto, then approximately vertical, slightly incurved behind the cell and below 
vein 4. Submarginal line pale, excurved at vein 7 and in centre. Hindwings whitish, ochreous brown at inner 
margin and dark brown at margin. $ 32 mm. Transvaal. Only the specimen illustrated is known as yet. 
C. vetusta Wlr. (Vol. 3, pi. 62 e). This and the following species differ in appearance by the many 
dentate lines on hindwings. Body and wings brown with yellow scales. Antemedian line on forewings, black, 
double, ixndidate, approximately vertical and diffuse. The black median line is double, proceeding oiitwards 
to median nervure, thence vertically, undulate and rather indistinct. Close distally an annulate mark on disco- 
cellular in fulvous surround. Postmedian line excurved between costa and vein 3, proceeding vertically from 
suljinedian fold. All 3 lines with a fulvous interfilling. Submarginal line fulvous, dentate, excurved at vein 7 
and in centre and with dark edges. Margin grey. On hindwings a double median and postmedian line and 
simple submarginal line. 35—38 mm. Bechuanaland, Soudan, Somaliland extending to India. As it also occurs 
in Syria and Algeria, it was already mentioned in Vol. 3, p. 339. — The name pallidior Strcl. denotes paler 
specimens. 
C. acrosticta Pnglr. (Vol. 3, jih 62 e) is described as a species from Palestine. Typical specimens are 
rather more reddish than shown by the illustration in Vol. 3, pi. 62 e. It also occurs in Egypt and in the Niger 
district; whether it is a form of as Hampson assumed, or whether it is a separate sjoecies, as is the opinion 
of Lord Rothschild, need not be examined here. The lines have a very similar arrangement and form, but 
the ochreous yellow or reddish ground colour give a very different impression. The black spot at apex is very 
striking. 
C. rosacea Rbl. (20 h). According to Warren this is also only a form of vetusta (Vol. 3, pi. 62 e). How¬ 
ever, if Hampson’s illustration is correct (which we are copying here), the markings vary a good deal. Ground 
colour reddish yellow. Antemedian and median lines are more vertical, rather inclined somewhat outwards. 
The postmedian and submarginal lines do not proceed towards the base on costa. On hindwings the formation 
of the lines does not vary. — nigrapex Strd. has a black spot at apex of forewings. 35 mm. Soudan, Socotra. 
C. canescens Wkr. (20 h). This species differs by the oblique formation of the lines. ^ grey-brown, 
$ somewhat darker. Antemedian line blackish, indistinct, very obliquely inwards below the cell. In paler median 
area, a few very indistinct dark lines extending obliquely inwards. Reniform stigma pale, with black surround, 
small and rarely distinct. Postmedian line black, arising near apex, jiroceeding to centre of inner margin, forming 
a large arc behind the cell and a smaller one outwardly on submedian fold. Distally traces of dark lines. Post¬ 
median line on hindwings black, undulate, straight. The space distally somewhat darker, enclosing 2 paler 
lines. 30—36 mm. Widely distributed, but apparently not common in South, South West and East Africa, 
also in Aden. 
Subfamily; Phytonietrinae. 
The usual name for this group of moths, that has been in use for over 100 years, is “Plusia” (= the 
rich.). The denomination was one of tlie happiest for these gold and silver spangled insects, but it has to be 
replaced by the name Phytoruetra according to a rigid observation of tlie rules of nomenclature, although this
