widely-separated localities, I believe G. stygianus, Butler, = G. irro- 

 ratus, Druce, = G. irroratus var. assamensis, Doherty. The type 

 of stygianus is in the collection of the British Museum and agrees 

 absolutely both with the too short description of irroratus by 

 Druce, and with the figure of var. assamensis, Doherty, in the 

 Jour. Asiatic Society of Bengal.

6 ?. Tore wing*: somewhat narrow and elongate ; costa widely 

 arched ; apex acute in d , more rounded in the $ ; termeii 

 straight or slightly convex ; tornus bluntly angulate ; dorsum 

 straight ; cell about half length of wing ; vein 6 from basal third 

 of 7 beyond apex of cell, upper discocellular therefore absent, 

 middle and lower discocellulars subequal ; vein 8 absent, 9 out of 

 7 not far from apex of wing, 10 from upper apex of cell, 11 from 

 apical half of subcostal. Hind wing* : elongate, oval ; costa and 

 dorsum long, very slightly arched ; termen regularly curved, 

 minutely dentate ; apex and tornus not well-marked. Antennae 

 long, longer than half length of fore wing, club gradual ; palpi 

 erect, slender, third joint long, aciculate ; eyes naked ; body long 

 and slender, especially in the <5 ; legs very long and slender, the 

 first joint of the tarsi remarkably so, but not flattened as it is in 

 Gerydus. <$ without secondary sex-marks. 



Key to the forms of Allotiuus. 



a. Fore wing: apex acutely and very narrowly 



produced ; termen conspicuously dentate, 

 tornus acutely produced and curved 

 downwards, dorsum Insinuate A. dnnnila, p. 297. 



b. Fore wing : acute in rf but not produced, 



generally blunt in $ ; termen not den- 

 tate or very slightly dentate, tornus 

 ^ bluntly angulate, dorsum straight. 

 a'. Fore wing upperside : with a curved 

 more or less ill-defined white discal 



fascia A. multintn'ffatus, p. 298. 



b' . Fore wing upperside : with a more or less 

 ill-defined elongate oval spot or broad, 

 short, straight discal streak. 

 n-. This spot or streak comparatively 

 narrow and small, dull white or 

 brownish white A. lorffMdi, p. 299. 



* A. drumila, Moore, a remarkable and very aberrant form, has the outline 

 of the wings somewhat different.
