MICROLEPIDOPTERA OF NEW GUINEA

family, and we can add no new general points to his descriptions, at least 
as far as the present Papuan material is concerned. 
The valva often possesses a small discal projection which with Philpott 
we indicate with the name of ampulla. A second, often long digitoid 
projection can sometimes be found in the middle of the base of the valva. 
The anellus may be equipped with long erect projections and is then 
called furca. The vitta (Philpott), a peculiar terminal filament of the 
aedoeagus, is in our material invariably missing; it is either altogether 
absent or possibly broken. The cornuti may be considerably developed, 
as e.g. in Anomoeosis phanerostigma spec. nov. 
As to the female genitalia, these are of a peculiar development and 
mostly well-differentiated. Ovipositor moderately long, erectile, telescoping. 
Ostium, a broad fold. Limen, often with one or three erect pointed 
projections and sometimes with two more large erect processes ventrally 
from these. Ductus bursae is strongly swollen along its proximal half and 
forms a large sack with retinate or finely papillate surface. Bursa copulatrix 
is large, elongate or even tubular. Signa, two, each with a flattened or 
concave proximal plate, bearing two slender horns with a finely dentate 
inner edge and a curved acute point. 
As Philpott rightly states, this type of the genitalia of the New Zealand 
Carposinidae has nothing in common with the genitalia of the Tortricoid 
families. Also in this respect the present family makes the impression of 
standing quite isolated, as is said above. However, our present knowledge 
of the genital characters of Carposinidae is too fragmentary to allow of 
any certain conclusions in that respect. It is possible that not the prevailing 
type of the genitalia as described above is the type which will be useful 
for phylogenetic hypotheses, but that one will have to look in the direction 
of deviating — perhaps more recent — forms. The male genitalia of 
several Carposinidae from Java and Sumatra, recently described, deviate 
considerably from that “archaic” type and are, therefore, interesting; 
some remind one of a certain type frequent in the Eucosmidae (Metacosmesis 
barbaroglypha Diakonoff, Treubia, vol. 20, p. 49, fig. 6, 1949); others are 
decidedly of a tortricid type (Mesodica infuscata Diakonoff, ibidem, 
p. 44, fig. 7). 
The country of origin of the present family appears to be South 
East Asia, which is supported by the distribution of the “archaic” forms 
i.e. those in possession of a developed vein 6 in the hind wing. One genus 
with this character is known from Australia ( Sosineura ), one from Japan 
(Conmiatarcha ) , one from Java {Mesodica), one from Java and Ceylon 
{Metacosmesis), and three from New Guinea. These last mentioned genera, 
which are described below, viz., Blipta, Xyloides, and Hystrichomorpha, 
certainly possess archaic features and facies ; Hystrichomorpha even forms 
in some respects a connection with the family Copromorphidae. Meridarchis 
which is often also in possession of a developed vein 6 in the hind wing, 
as is said above, is rather wide-spread and occurs throughout India,
