3o8 SOUTH-AFRICAN BUTTERFLIES. 



median nervule at some distance from latter's origin. Hind-wings : 

 large, prolonged inferiorly (especially in ^) ; costa very prominent at 

 base, thence moderately arched ; hind-margin slightly sinuated ; anal 

 angle rather pronounced in ^, rounded in $ ; inner margins forming a 

 complete but not deep groove ; costal nervure extending to apex ; 

 upper disco-cellular nervule rather long, united to second subcostal 

 nervule not very far from latter's origin, bent slightly outward, — lower 

 one slender but quite distinct, gently curved, joining third median 

 nervule just beyond latter's origin ; internal nervure short, not reaching 

 beyond middle of inner margin ; discoidal cell very short. Fore-legs 

 of ^ very slender, scaly, — femur with a fringe of hair beneath, tibia 

 considerably shorter than femur, — tarsus less than half as long as tibia, 

 tufted thinly with fine hairs ; of the $ much larger and thicker, with 

 tarsus distinctly articulated, not at all hairy, fully two-thirds the length 

 of tibia, and spinose near extremity beneath. Middle and hind legs 

 rather long and thick ; femora smooth, slightly curved ; tibia3 spinu- 

 lose above, armed beneath (especially middle pair) with unusually long 

 spines, and with long terminal spurs ; tarsi thick, finely spinulose 

 above, very spinose beneath, with terminal pair of spines on each arti- 

 culation longer than the rest. 



Abdomen short (less than half as long as inner margins of hind- 

 wings) ; very slender in ^. 



I have followed Mr. Kirby (Sgnon. Cat. Diitrn. Lcp., 1871, p. 

 249) in adopting for Dcvdcdus, Fab. (= Meleagris, Cram, and Drury), 

 distinct generic rank from Atcrica under Hiibner's name, Hamanumida, 

 because, on comparison with A. JRahcna, Boisd., the type of Atcrica, I 

 found that the characters of the former (which are those given above) 

 differed very considerably from those of the latter. Besides the closed 

 cell of the hind-wings noted by Westwood {loc. cit.), Dccdalus presents 

 the following differences from Aterica, viz., antennae much shorter, 

 with very much shorter, thicker, more cylindrical, and bluntly-tipped 

 club ; palpi much more hairy both above and inwardly ; thorax longer 

 and more robust; fore- wings less acuminate apically, especially in $, 

 with the third subcostal nervule originating much nearer to apex, and 

 the lower disco-cellular nervule shorter ; hind-wings not so prolonged 

 inferiorly, with costa not at all hollowed beyond middle, and more 

 roundly convex at base, and with the upper disco-cellular nervule 

 much longer, and not forming merely a curved base for the radial 

 nervule ; fore-legs of the $ with tarsal joints more distinct ; middle- 

 and hind legs with the tibiaa much more strongly spined ; and abdo- 

 men shorter. 



I have not had the opportunity of examining the West-Afri- 

 can Veronica, Cram., which (as noted above under Euryphene cceruica) 

 looks much like Deeded us, and cannot, therefore, judge whether Hiibner 

 rightly associated that species with Daxlalus in his genus Hama- 

 numida.
