PI. jonesi Barnes & Ben), is similar to nigrita (169 d), but smaller, with shorter antennal pectinations. 
In jonesi , veins 4 + 5 of the forewing are not stalked as a rule. Separated from nigrita by the antennae and 
the genitals. Described according to 20 from Texas. — On the occasion of this description another species 
is mentioned, which may be identical with jonesi or gloveri of which no more material is preserved in the col¬ 
lections. 20 (J bags yielded lepidoptera which had the same antennae as jonesi , but black wings as in confederata, 
without the brown tints of jonesi and nigrita. The larvae fed on blossoms and delicate leaves of Crataegus, but 
neither on leaves of fruit-trees nor on grass. The bags resemble those of gloveri, they are therefore only spun 
over with very fine particles of plants, not with large pieces. 
Of the following three species only the larval hags are known. 
PI. tandilensis Kohler. The bag is 18—22 mm long, covered almost in parallel order with grass-pieces 
of different lengths, some of them being longer than the bag. Diameter 3—4 mm. The larva lives on Gramineae, 
but the adult larva may also feed on the blossoms of the Malvacea Pavonia cvmbalaria. Argentina. 
PI. rngosus Kohler was described from the same district. The bag is just as long, but thicker, spun 
over with obliquely arranged parallel remnants of herbs, not of grasses, though it feeds on grass. 
14. Genus: Oiketicus Guild. 
While the genus is represented only by 2 species in the Indo-Australian Fauna, the American Fauna 
contains 12, some of which occur in the Southern States; of 3 species only the bag is known. In the oblong 
forewing veins 4 -)- 5 and 7 + 8 + 9 are stalked, a few spurs extend from the inner marginal vein to the inner 
margin. Hindwing almost triangular. Anterior tibiae with a long thorn. 
Of the first three species only the bag is known. 
Oi. westwoodi Berg. The bag is about 90 mm long, 25 mm thick, conical, spun over with few particles 
of plants, similar to that of geyeri. According to Koehler, the size is 60 and 18 mm. The larva is similar to 
that of kirbyi but discernible by white dots on the dorsum of the segments 4 to 6, which are hardly noticeable 
in kirbyi. The rest of the body is similarly coloured, only the head is redder. The antennae and parts of the 
month being white in kirbyi are red here. Body with more numerous and more distinct black lateral dots than 
in kirbyi. On species of Piptadenia. Argentina. 
Oi. elegans Kohler. The bag is 22—28 mm long, grey, 4 mm thick, somewhat narrower towa the 
end. Not spun over with particles of plants. On tree-like Leguminosae. The case seems to be very small for 
a species of Oiketicus. Described from Argentina. 
Oi. davidsoni H. Edw. According to Dyar. the species surely belongs to some other genus, since the 
bag is longitudinally covered with branchlets which are partly longer than the bag. Length of bag: 40 mm. 
Oi. geyeri Berg (= tabacillus Weyenbgh.) (169 e). Widely distributed, but much rarer than kirbyi. 
Antennae blackish. Forewing reddish brown, body more yellowish, hindwing lighter, somewhat diaphanous. 
Forewing without any marking, but the bar of the two inner-marginal veins seems to be somewhat lighter. Corre¬ 
sponding to this scheme of markings, which is quite different from that in kirbyi, the larval bag is also different, 
up to 60 mm long, 12 mm thick at its upper end, then slowly getting narrower, 4 mm thick at the end, quite 
smooth, looking at the end as if it were torn. According to Koehler's statement, the does not ermerge at 
this end. but the larva makes an opening for emerging about ] 3 distant from the end. Berg states the bag 
to be 80— 120 mm long, which seems to be rather much. On species of Acacia. The imago, 36—48 mm large, 
is known from Venezuela, Uruguay, Argentina. A very dark specimen which, however, presumably does 
not belong to specter is before me from Blumenau from the Senckenberg Museum. 
Oi. specter Schs. forms a transition to kirbyi and the allied species. Body dark greyish brown, wings 
the same, scantily scaled. Forewing with a paler grey cross-vein, the space in and behind the cell darker grey, 
the same at the base at the inner margin. Hindwing dark grey at the inner margin. 50 mm. Venezuela. 
Oi. kirbyi Guild. (= fugurator H.-Schdff., gigantea Z.) (169 e). Antennae blackish. Body and wings 
dc\rk red-brown. The cell of the forewing is very dark, also the space behind it as far as the bifurcation of veins 
8 + 9 and downward as far as the upper inner-marginal vein. Cross-vein white with feeble outward dents. 
In the copulation the abdomen of the is stretched to 2 or 3 times its length. 38—45 mm. Central America 
to Brazil, also in Cuba. platensis Berg (169 e) is somewhat smaller and of a much lighter ground-colour, but 
the dark places almost just as dark as in kirbyi, thus more contrastingly marked. 35—38 mm. Argentina, 
Uruguay. — mexicanus Heyl. (169 f). I have not seen the description of this form, but only the type in the Berlin 
Museum. It is allied to platensis by the ground-colour being almost just as light, but it differs in the shape 
of the hindwing which is straight at the distal margin in kirbyi, well rounded in platensis, distinctly inserted 
in mexicanus as well as in poeyi. poeyi Lucas (169 e) is somewhat more slender, still darker than kirbyi, the 
margin of the hindwing is strongly inserted. 36—42 mm. Cuba, Portorico, also from Blumenau. —- The bag 
differs from the smooth conical shape of westwoodi and geyeri, it is 45—50 mm long, strongest at 1 of its length.
