New Britain (type) and New Ireland. — angustimargo Prout, from the Solomon Islands, has the distal border angusii- 
considerably narrower, in its typical form (from Rendova) measuring only ] y 2 to 2 mm, at the apex of the margo. 
forewing 3 —4mm; its proximal edge scarcely crenulate. Expanse in the <$ 36—42 mm, in the $ 48 mm. 
Remarkably similar to uniformis, which is larger and has the borders more lead-coloured (here blacker); more¬ 
over the present species lacks the whitish line between ground-colour an border. A <$ from Choiseul has the 
borders somewhat less narrow, possibly another race. 
21. Genus: KpicosymMa Warr. 
(See Yol. 16, p. 56.) 
Near Scopula in most characters, but with the <$ antenna strongly pectinate (as in only a few African 
Scopula), the areole of the forewing double, etc. Genitalia of the S much as in Scopula, but with a well deve¬ 
loped uncus. In Africa, the chief home of the genus, there are two sections recognized, according to the 
armature of the hindleg; the Indian forms belong to the section Anacosymbia Prout, i. e. the tibia without 
spurs. 
E. albivertex Swinh. (15 i). Somewhat larger than its African congeners, the <$ hindtibia with a strong albivertex. 
hair-pencil. In tone strongly reminiscent of Organopoda and Discoglypha, the cell-dots simple, the apex of the 
forewing not very acute. The name-typical race is N. Indian, the type from the Khasis; a “Pulo Laut (Do¬ 
herty)” S in the British Museum, from the Elwes collection, agrees so exactly with one from the Naga Hills, 
from the same collector, that I assume an error in labelling. — ancillaria Warr., from S. India and Ceylon ancillaria. 
is on an average smaller and generally of a duller, less reddish brown, not very sharply marked. 
A. conspersa Warr., founded on a $ from Sumba, is probably a further race, though the type has conspersci. 
lost its hindlegs. It and a $ from Portuguese Timor which I associate with it are still smaller than ancillaria, 
similar in tone, vertex perhaps less clear white, postmedian line on both wings perhaps more sharply expressed. 
22. Genus: l^issoblcmma Warr. 
(See Vol. 16, p. 57.) 
This genus is also common to India and Africa, each fauna contributing one species. Very near Soma- 
tvna, perhaps a section thereof. Antenna of the q pectinate (as in few Somatina), forewing with the apex fal¬ 
cate, costa rather strongly arched, 2nd subcostal arising from the cell. Hindtibia of the <$ without spurs. 
L. lunuliferata Walk. (15 i). A relatively large and rather striking insect, which cannot be confused lunuliferata. 
with any other known species. Apparently confined to S. India, the type from Canara. 
23. Genus: Autstiiepsisi Turn. 
Palpus rather short. Antenna of the <$ dentate-fasciculate. Hindtibia of the not dilated, with ter¬ 
minal spurs only ($ probably with 4 spurs). Forewing with areole double, 2nd subcostal from the cell, 2nd 
radial from slightly before the middle of the discocellulars. Hindwing with 2nd subcostal and 1st radial quite 
shortly stalked. Type and sole species: poliodesma Turn. It could perhaps be made a section of Dithalama, 
like Pylarge of Scopula , but the shape and pattern are different. 
A. poliodesma Turn. (15 g). Recognizable by the generic characters and the pale leaden-grey irroration poliodesma. 
and markings. Brisbane. 
24. Genus: Dfthsilama Meyr. 
Characters as given under Autanepsia except that the A hindleg has the tibia flattened and distorted, 
without spurs, and the tarsus much shortened; 2nd subcostal of hindwing somewhat variable, occasionally 
connate instead of stalked, but apparently never separate. Erected for a single species, cosmospila; I have 
left with it 3 others which perhaps fit better into it than into true Somatina, but which have not yet been closely 
studied. All are Australian and of i-ather small size. 
D. punctilinea Swinh. (= tetrasticha Lower) (15 h). Antennal ciliation short. Palpus moderate. A punctilinea. 
whitish species with the lines indicated by 4 series of grey dots, the outermost blacker. W. Australia, Swin- 
hoe’s type from Sherlock River, Lower’s from Derby. 
D. cosmospila Meyr. (15 h) is the most ornate Dithalama, the coloured outer irregular band quite cosmospila. 
characteristic. Described from New South Wales and subsequently recorded from Victoria. Said to frequent 
Eucalyptus.
