Mr. A. G. Butler on the Genus Hypocala. 19 



F. Wings below with costal and apical areas smoky prey, 

 the black or blackish bars on the primaries almost 

 united at lower extremity, the outer one diffused ; 

 the black or blackish external belt of secondaries 

 broad, externally and apically diffused, excepting 

 towards anal angle, where it is interrupted by a 

 marginal clavate streak or spot. 



a. Size of H. andremona, secondaries above with pale 

 ochreous markings ; external black border decreasing 

 towards anal angle, deeply excavated just above the 



angle //. Moorei. 



b. The largest known species ; below deep ochreous, 

 the inner black bar of primaries with an external denticle ; 

 discocellular bar of secondaries broad and externally 

 angular ; hind wings above with deep ochreous markings ; 

 external black border very broad before anal angle, 

 moderately excavated just above the angle H. australice. 



c. Similar to b, but with the whole under surface and 

 the upper surface of the secondaries smoky, obscuring 

 the markings, which are also paler and less defined in 

 themselves If. velans. 



Of the above species, all of which are represented in the 

 Museum collection, we possess all three varieties of two species 

 only. For the convenience of students of the group I give 

 the following arrangement of the varieties, classified according 

 to the colouring of the primaries, whether uniform, variegated, 

 or bicoloured : 



Uniform. 



H. subsatura. 

 H. dcflorata. 

 H. guttiventris. 

 H. andremona. 



H. australice. 

 H. velans. 

 H.forem (Mab.). 

 H. clarissima. 

 H, violacea. 



Variegated. 



H. aspersa. 

 H. plumicornis. 

 H. lativitta. 

 H. Pierreti. 

 H. Moorei. 



If. velans. 

 H.Jlorens (Mab. 



Bicoloured. 



H. limbata. 

 H. rostrata. 



H. flvrens (in B. M). 



It seems probable that the first and second forms (which 

 appear to be inconstant and merge into each other) are one 

 brood, and the very distinct-looking third form another; that 

 they represent in fact either spring and autumn or dry- and 

 wet-season forms of the species. Whether this is so or not 

 can only be proved by breeding, and it is worth the con- 

 sideration of those who have the opportunity of obtaining the 

 eggs or larva;.
