ELYMNIINZ.. 169 
Genus AGRUSIA. 
Imaco.—Male. Forewing very short and broad, triangular ; costa much arched, 
apex obtuse ; exterior margin almost erect and very slightly scalloped, posterior 
angle rounded; posterior margin long, with the middle longitudinally folded wpon 
the upperside and covering a scabrous patch of scales below the submedian vein, the 
patch with an erectile tuft of hairs arismg from the inner end; cell short, very broad. 
Hindwing short, and very broad, triangular; anterior margin arched at the base, 
apex obtuse, exterior margin obliquely-convex and almost even, anal angle obtuse ; 
the normal glandular tuft within the cell ; the cell short and broad. 
Typz.—A. EHsaca. 
The species of this genus are mimics of the Nymphalid butterflies of the 
“protected” section of the genus Huthalia—of which lepidea, ambalika, Diardi, 
Andersonti, etc., are representatives. 
According to Mr. W. B. Pryer (Ann. Nat. Hist. 1887, p. 50) the 4. Esaca is 
found in N. Borneo, ‘in fairly open ground, in sunshine.”

Imaco.—Male. Upperside dark olivescent violet-brown. Forewing with a 
marginal excurved series of lilacine-grey spots, the three upper of which are of a 
lengthened oval form, and the three lower pyriform with the point acute. Hind- 
wing with a broad marginal scalloped-edge lilacine-grey band. Underside pale 
vinous-brown, the apical area of forewings and the exterior marginal area of hind- 
wings whitish ; covered with numerous darker brown more or less confluent strigze, 
which are broadest from the disc to the base. Female unknown. 
Expanse, ¢ 25 inch. 
Hasitat.—Mergui Archipelago. 
This species is, apparently, a mimic of the Nymphalid Huthalia Andersonii. 
Distrisution.—A single specimen was taken by Dr. J. Anderson at Minthan- 
toung, Mergui, in December.
