XVI. On Pyralidina from the Malay Archipelago. 
By Epwarp Meyrick, B.A., F.Z.S. 
[Read May “nd, 1894.] 
THE collection which forms the subject of this paper 
was made by Mr. W. Doherty, and is in the possession 
of Mr. H. J. Elwes, who entrusted me with types of the 
species for examination. The localities from which the 
specimens came comprise the Island of Sambawa, 
Celebes, Pulo Laut (Borneo), and §.E. Borneo. Many 
of the species are new; the large number of new and 
curious species of Oligustigma is especially remarkable. 
The fauna of Sambawa has evidently felt the effects 
of isolation, several of the species that occur there 
varying in a marked manner from the normal type of 
the same species occurring elsewhere. 
PYRAUSTIDA. 
ANISOCTENA, n. g. 
Forehead oblique ; ocelli present ; tongue developed. Antenne 
4,in ¢ with a sinuation at 4, basal fourth with short very uneven 
pectinations, longest on sinuation, twice fluctuating between that 
and base, with a notch above basal joint surmounted by a strong 
tooth. Labial palpi rather long, curved, ascending, second joint 
much thickened with dense projecting scales, terminal joint 
moderate, thick, obtuse. Maxillary palpi moderate, terminally 
dilated with scales. Thorax in ¢ with patagia forming a dense 
central tuft. Abdomen in g with lateral hair-tufts beyond middle, 
and dense black genital tuft. Posterior tibiee with outer spurs 
about half inner. Forewings in g with inner margin densely tufted 
with hairs towards base ; 3, 4, 5 approximated at base, 10 approxi- 
mated to 9. Hindwings densely haired above towards inner margin 
and on lower edge of cell towards base ; 3, 4,5 approximated at 
base, 7 out of 6 near origin, anastomosing with 8 to +. 
Allied to Margaronia, but with many curious characters. 
The hairy margin of cell of hindwings is, of course, 
abnormal in the Pyraustide.
