P. apicata Hmps. (= dimorpha Dyar) (35 k) is on the silvery grey forewing irrorated with light apicato 
brown and in some places with red-brown, with a triangular dark brown costal-marginal spot in the centre, 
and a large dark brown apical spot; the undulate transverse lines are double, the maculae surrounded with 
red-brown, the strangulated reniform macula dark-centred; undulate line indistinctly light. Hindwing coppery 
brown, before the grey marginal lunae darkened. Panama. 
46. Genus: Matopo Dist. 
To this otherwise purely African genus two South American species have been reckoned of late. Pro¬ 
boscis developed; the frons exhibits a large rounded projection with a horny plate below' it; the thorax is 
scaled and exhibits loose tufts in front and behind, whilst the abdomen only shows a basal tuft. 
M. neotropicalis Jones (36 a). Head and thorax lustrous black, the forewing on the whitish ground neotrojn- 
irrorated with light red-brown, in the apical half of the costal margin darkened by blackish-brown; the anterior 
transverse line and the ring-macula are absent, only a double median line and behind it a whitish distal transverse 
line are present ; the reniform macula is a small whitish luna; in the marginal area the veins and between them 
internerval streaks are dark-striped, in the lower half partly connected in the shape of a very elongate V. 
Hindwing of a pure white. Brazil. 
M. giacomellii Dgn. Forewing grey, in the distal half excej:>t the margins white, this white ground giacomellii 
is traversed by a grey band-shaped line obliquely extending from the apex to the hind-margin, in which line the 
veins are prominently blackened; the maculae are white, the reniform macula in the middle traversed by the 
grey cross-vein. Hindwing diaphanous white. Argentina. 
47. Genus: Delta Sadm. 
Beside African and oriental species, this genus also contains South American representatives recalling 
Cucullia in the long narrow shape of the wings and the somewhat keel-shaped erect collar. The thoracal covering 
is intermixed with scales, the dorsum exhibits a comb-shaped, parted hair-tuft, the abdomen shows tufts on 
the first rings; the legs are long-haired. 
D. goniosema Hmps. ( — ramosula Drc. nec Gn.) (35 k). Forewing light grey, irrorated with reddish- goniosema. 
brown, particularly around the low'er cell-end, with darker striped veins and a black basal ray; the ring-macula 
is very long and oblique, the reniform macula white, centred with reddish, and inwardly produced on the median; 
in the subterminal area there are black internerval streaks, and the ends of the upper median branch and lowest 
radial branch are marked in the shape of a pointed W. Hindwing light brownish. Mexico. 
D. ramosula Gn. (36 a) is very similar to the preceding, larger on an average, the reniform macula ramosula. 
below not produced and thereby easily separated. Canada; Northern. Eastern, and Central States. 
D. stewarti Grt. (36 a) is at once discernible by much darker hindwings which are deep blackish-brown; slewarti. 
also the forewing is on the violettish-grey ground irrorated with a darker red-brown, the maculae are more 
distinctly marked. United States (Washington to California). 
D. nea Drc. (36 a) has much narrower forewings which are irrorated with reddish-ochreous, at the nea. 
costal margin and hind-margin with dark brown; the partly extinct transverse lines are very strongly dentate; 
no maculae except a narrow lunula representing the reniform macula; subapically at the distal margin a brown 
triangular spot. Hindwing yellowish-white, at the margin and on the veins darkened. Mexico to Colombia 
and Bolivia. 
D. albiclava Drc. (36 a) is smaller, much darker red-brown with black-striped veins of the marginal albielaca. 
area, with a black basal ray as far as the very long white coniform macula which is surrounded with black; 
behind the yellowish lunula of the reniform macula there is a distinct black dentate posterior transverse line, 
the apex is parted by a light patch. Hindwing reddish-brown with darker striped veins. Peru. 
48. Genus: Andropolia Grt. 
A large genus of North-American species with a developed proboscis, a short, straightly porrect 
last palpal joint, with hair-fillets on the smooth frons, the thorax clad with scales intermixed with hairs; pro- 
and metathorax with loose tufts, the abdomen which is roughly haired at the base exhibits quite a series of 
such tufts.
