NOVITATES ZOOLOGICAE XXIII. 1916. 123 



AI. ant. long. 22-24 mm. 



Hab. Vella Lavella, Solomon Islands, February and March 1908 (A. S. 

 Meek) ; 3 ? ? . 



Near M. melas R. & J. (1903), which it represents, apparently, on the Solomon 

 Islands. It is easily distinguished from melas by the outer margin of the black 

 antemedian band of the forewing being strongly curved proxirnad posteriorly, 

 the postmedian band of two lines being entirely filled in with black, and by 

 the yellow band of the hindwing (which varies very much in melas) being 

 represented by a small, elongate, subcostal patch and an obsolescent, diffuse cloud 

 placed in front of the abdominal margin (in one of our three examples both 

 markings are barely vestigial). Moreover, the yellow basi-abdominal patch of 

 the hindwing extends only halfway to outer margin. 



In the type-specimen there is a trace of a yellow side-spot on the third 

 abdominal segment.

Al. ant. longit. : 22 mm. 



Hab. Near the Oetakwa R., Dutch South New Guinea, up to 3500 ft., October — 

 December 1910 (A. S. Meek) ; 2 ? ?. 



Body glossy blue. Wings velvety black above, with a blue sheen in certain 

 lights ; tips of fringes of both wings greyish white ; on forewing a short streak 

 on the subcostal and median veins, and another, somewhat longer, on the submedian 

 glossy blue, united at the base, an orange {type) or red median band from the costa 

 to hindmargin, the fringe of the hindmargin remaining black, the band just 

 proximal to the discocellulars, the upper angle of the cell being black ; distally 



of the band a few scattered glossy blue scales. On hindwing the band red, 



abbreviated in front, extending forward to the subcostal or a little beyond it ; in 

 the basal area two glossy blue streaks, one on the median, the other on the sub- 

 median, both extending from the base close to the band. 



On underside the forewing nearly as above, the band reddish behind, and the 

 blue scales outside it more numerous. On the hindwing two blue streaks, the first 

 placed on the costal and subcostal, the second on the median vein. 



Veins SC 2 and R 1 of the hindwing (6 and 7) on a very short stalk in type, 

 separate in second specimen.
