 Frontal tubercle strongly bifid, the points yellow behind,

 with light rufous, surmounted on each side with a purplish 

 mark. Rhinarium, lower part of nasus, and middle and sides 

 of mentum varied with ligiit rufous brown. Face set with 

 short black hair ; mentum very coarsely punctured. Thorax 

 light rufous brown in front and on the sides ; three broad 

 slightly oblique yellow bands on each side, in front of which 

 the rufous colouring is varied with iridescent purple. The 

 space between the wings is rufous brown ; the scapulaj are 

 yellow, corresponding to the first lateral stripes, bordered by 

 a black carina in front, and there are apparently four yellow 

 spots behind, one in the middle of the space between the fore 

 wings, one just behind the fore wings on each side, being the 

 continuation of the second lateral stripe, and one between the 

 front of the bases of the hind wings. Abdomen with the 

 first segment and the base of the second rufous brown; the 

 rest of the abdomen black ; the second segment with a broad 

 yellow band, indented in the middle in front, in front of and 

 slightly overlapping the carina ; the third with a narrow 

 tawny band in front and a broader one in the middle, almost 

 divided by the median line; the fourth, fifth, and sixth 

 similarly coloured, but the second tawny space narrower and 

 more or less connected on the sides with the first ; the seventh 

 segment with the front half tawny, divided on the sides by a 

 narrow black line ; the terminal segments mostly rufous on 

 the sides. Appendages of the second segment rather large, 

 black in front, the last portion yellow ; terminal appendages 

 about as long as the ninth segment, the upper ones yellow, 

 the lower one broad, truncated at the extremity, rather 

 darker yellow, with the sides bordered with brown. Legs 

 long, black, thickly set with long slender bristles ; front legs 

 yellow beneath to three fourths of the length of the femora.
