1. Eusphalera satisbonensis spec. nov. 



c? ?. Variabilis, E. semiflacae Jord. (1904) vicina, abdomine supra flavo, capite 

 et tiiorace et ventre nigro-C3'aneis. 



Al. ant. long. : 20-24 mm. 



Hub. Goodenongh I., d'Entrecasteanx Islands, March— May 1913, 2500-4000 ft. 

 (A. S. Meek), a series of both sexes. 



Agrees in the yellow tipper surface of the abdomen most nearly with E. lutescens 

 B.-Bak. (1908), but in the latter species the nnderside of the abdomen is creamy 

 or pale straw-colour. 



The species is very variable, both sexually and within each sex. 



c?. Body black, with a cyaneous gloss, upper surface of abdomen yellow with 

 the exception of segments 1 and 8, the former often having a yellow spot at the 

 apex. Sometimes the yellow area of the abdomen suffused with black. According 

 to the wiug-markings we group the specimens as follows : 



(a) f. satisbonensis. — Forewing, above, basal two-thirds orange-yellow or 

 yellow, extreme base, costal edge, hindmargin and apical third dull black, with a 

 faint purplish sheen on the veins and the fringe in certain lights, and sometimes 

 traces of metallic subapical spots. Hindwing somewhat paler yellow or orange than 

 forewing, costal and distal margins broadly bordered with black, the distal border 



slightly dentate at the veins, extreme base likewise black. Underside : the 



yellow areas paler than above, base of forewing suffused with black in front of 

 hindmargin almost to outer edge of yellow patch. Marginal border of hindwing 

 with more or less distinct blue submarginal spots. 



The yellow area of the forewing aboce sometimes invaded by black from the 

 hindmargin. On underside the hindwing in some specimens with black longitudinal 

 streak. 



(h) f. plagiata nov. — Forewing, above, with bi- or tripartite orange subbasal 

 spot and orange-yellow patch at end of cell more or less distinctly invading the disc 

 proximally to lower angle of cell, the tint variable, but the basal spot deeper coloured 



thau the patch. Hindwing as before. Underside : patch of forewing replaced by 



a more or less abbreviated and strongly tapering band. Hindwing as before. 



In one of the specimens the basal spot is enlarged and, moreover, connected 

 below costa with the median patch ; the latter is continued by some spots 

 forming a narrow diffuse band directed towards hind angle. Transition towards 

 form {a). 



(c) f. fasciata nov. — Like {b), but the median patch replaced by a well-defined 

 oblique band, which does not quite reach hind angle and is broadest anteriorly. 



The genitalia of these three forms are alike. They are characterised by the 

 clasper bearing a large tooth as in E. semijiava, and having the tip of the long 

 slender apical process somewhat broadened, recurved and excavated. 



?. This sex appears in two forms, which are not connected by intergradations. 

 The metallic markings are more conspicuous than in the S , at least below, the first
