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



A. Wings below pale ochreous ; primaries with black 



discal patch divided by a band of the ground-colour ; 

 secondaries with a black spot at end of cell and an 

 oblique bar from anal angle to second median branch. 



a. Black patch on primaries broadly divided, leaving 

 only a narrow bar of black on its inner edge ; spot of 

 secondaries small and anal bar very narrow H. clan'ssima. 



b. Black patch barely divided by a narrow central bar ; 



spot of secondaries elongated, anal bar broad S. violacea. 



B. Wings below ochreous, greyish on costal and apical 



areas ; primaries with a black discal patch enclosing 

 an ovate transverse ochreous spot ; secondaries with 

 a black spot at end of cell ; an irregular, partly mar- 

 ginal, black band from anal angle to just above lower 

 radial vein, its outer edge interrupted by two spots, 

 that nearest anal angle small and angular H.Jlorens. 



C. Wings below ochreous, irrorated with purplish grey 



on costal and apical areas ; primaries with the usual 

 black discal patch represented by two rather broad, 

 abbreviated, parallel, oblique bars ; secondaries with 

 a conspicuous spot at end of cell ; the usual blackish 

 band narrow, irregularly zigzag, broadly expanded 

 at its upper extremity and extending from close to 

 anal angle to second subcostal branch H. deflovata. 



D. Primaries below almost as in B, but the black patch 



bounded below by the first median branch ; disco- 

 ceUular spot quadrate ; the blackish band zigzag, 

 alternately narrow and broad, extending from near 

 anal angle almost to the first subcostal branch. 



a. Secondaries above chiefly ochreous, much more so 

 than in any other described species H. guttiventris. 



E. Wings below with cell of primaries and inner two 



thirds of secondaries bright ochreous, remainder of 

 ground-colour paler ; apical area greyish, the latter 

 and costal border striated with brown atoms ; pri- 

 maries with two broad black bars, converging at 

 their lower extremities. 



a. Secondaries with a short, oblique, narrow, irregular 

 black bar on the discocellulars ; outer border blackish, 

 shading into brown towards costa, becoming paler on 

 margin towards apex and interrupted towards anal angle 

 by an unequal, angular, ochreous, marginal patch towards 

 anal angle , H. andremona, 



h. Primaries with the black bars broader, almost 

 touching at lower extremities ; the inner bar emitting a 

 broad grey streak below the cell almost to the base; 

 secondcaries with the blackish portion of the outer border 

 broader, emitting a black denticle towards the lower 

 extremity of the discocellular bar, interrupted towards 

 the anal angle by two separate marginal ochreous spots. H. subsatura.
