5 . — Black, yellow and white. Head black, narrowly margined with 

 yellow behind the eyes. Palpi black. Antennae black, finely annu- 

 late on basal half with white. Prothorax black, with a few yellow 

 hairs. Patagia yellow. Thorax and abdomen black, above and be- 

 low. Anal claspers very large, black, hairy. Legs black ; tips of 

 basal joints of tarsi white ; tibiae of two anterior pairs clothed with 

 orange scales. 



Anterior wings deep velvety black, with distinct metallic blue scales 

 on the discal vein, on the basal third of the costal area, and along the 

 submedian vein ; on the latter vein they diminish in number out- 

 wardly. A wedge shaped pale sulphur yellow spot at base, with the 

 outer angle rounded, and divided longitudinally by the black median 

 vein. A small sub-trapezoidal yellow spot in the discal area ; and a 

 transverse band on the median nervules, very pale, almost white, 

 divided into six areas by the black veins ; the sixth of these spots, or 

 the one nearest the costa, is very minute, the others subequal. This 

 band is of nearly equal width throughout, and terminates abruptly on 

 the 4th median vein. The costa is strongly swollen and thickened 

 near the middle, forming a groove apparently for the reception of the 

 antennae, such as we find in many elakridce and curctdionidce. 



The secondaries are also velvety black, with clear while markings. 

 These consist of a basal spot which leaves a wide black margin on the 

 inner border ; is clearly divided into two by the black median vein, 

 and again very faintly divided nearer the costa. An outer band across 

 the nervules divided into five spots by the black nervules. The sec- 

 ond of these spots is the longest, diminishing to the last, which does 

 not reach the fourth median. The costal area is also whitish. 



Beneath, the markings of the primaries are reproduced, but are 

 white with only the faintest tinge of yellow on the basal spot which is 

 enlarged so as to reach the inner margin. Secondaries as above, ex-
