Chresmareha pythia, Diakonoff, (wee Meyrick), Zool. Meded. Mus. Leiden, 
vol. 21, p. 142, 1939. 
Distribution: British New Guinea. Owgarra. 
$ 26 mm. Head deep orange-fulvous, face white. Palpus rather long 
deep orange-fulvous, terminal joint minute. Thorax silvery-white, edged 
with deep orange-fulvous anteriorly, prothorax yellow below. Abdomen 
glossy, dark leaden-grey, anal tuft pale ochreous- whitish, preanal segment 
ochreous below. Pore wing somewhat broader than in female, with broad 
costal fold reaching to beyond 1 / 4 > 't- s inner edge convex throughout, 
gradually curved, ciliated along apical */ 4 . In all other features similar to 
the female. 
Legs in both sexes black. Female 28—29 mm, fore wing in one specimen 
somewhat broader than in other two. Abdomen very long, corethrogyne 
light fulvous-ochreous, tinged bronze. 
Baliem Camp, 1700 m, November 16—27, 1938, “flying in daytime”. 
Three males, two females. Differs from Meyrick’s description by absence 
of yellow suffusion along costa and of ochreous suffusion in costal cilia, 
the latter being snow-white, but we nevertheless regard this material as 
conspecific. 
Now that we are better aquainted with this large genus, we are satisfied 
that the synonymy published in our above mentioned paper can be 
maintained no longer', and that it is better to regard both pythia Meyrick 
1920 and /Mia Meyrick 1924 as good species, distinct from patarea, 
pending further evidence by close study of the genitalia of the type 
specimens of these species, which are in the British Museum and not 
available to us at present.
